Phased Array Pulser Receiver
In the ISONIC 2009 UPA Scope PA Pulser Receiver is controlled through the intuitive operating surface combining classiic user interface of ultrasonic flaw detector and the ray-tracing graphics
Types of waves to be generated in / received from the material are controlled / selected through entering the value of the corresponding ultrasonic velocity in the material. The instrument screen movie below
illustrates an example of switching between longitudinal / shear wave whilst the wedged linear array probe is placed on the IIW-I (V1, K1) block receiving the signal from 100 mm radius concave cylindrical surface (the wedge angle
of 36°exceeds the first critical angle)
The trace of ultrasonic beam, probe footprint, focal points, apertures, etc are truly imaged upon entering thickness, OD, and other data characterizing geometry of the material
Whilst performing inspection with the use of wedged linear array probes according to the S-, B-, or other scan plan it is possible to add a number of additional focal laws to the main sequence.
The calibration for each such focal law is performed through the Phased Array Pulser Receiver dialogue. The instrument screen video below illustrates activation of 0-deg compression wave pulsing-receiving
focal law in order to monitor coupling between the probe and material through evaluation of the back wall echo amplitude (the same focal law allows detection of laminations in the parent material under
the probe at the same time):
Signal presentation and evaluation for the A-Scans obtained through implementing of the desired focal laws is fully compliant with the conventional UT codes and procedures
DAC and TCG may be created through collecting echo amplitude / time of flight data from up to 40 reflectors (points) or through entering dB/mm (dB/inch) factor.The photos and video below
illustrate the use of the typical calibration block for creating a DAC through collection of echoes from the Flat Bottom Hole (FBH) obtained through the half-, full-, 1.5 skip insonification:
The videos below illustrate preparing DAC for the other commonly used reference reflectors, namely, the EDM Notch and the Side Drilled Hole (SDH):
The above allows using of the same concepts and calibration blocks as for conventional UT and extremely simplifies calibration of the instrument prior to the electronic scanning

B-Scan / S-Scan
Cross-sectional insonification and imaging of the material may be provided electronically with use of linear array probes through:
Linear scanning with ultrasonic beam at predetermined incidence angle through reallocating of fixed size emitting/receiving aperture within entire array and composing of B-Scan image
Sectorial scanning with ultrasonic beam produced by fixed emitting/receiving aperture through steering of incidence angle in the predetermined range and composing of S-Scan image
Combining linear and sectorial scanning
etc
The effects of inequality of elements of linear array, varying sound path and loss in the delay line or wedge, dependency of energy of refracted wave and effective size of emitting/receiving aperture on incidence angle should be compensated to equalize the sensitivity over insonified cross-section. The unique feature of ISONIC 2009 UPA Scope is the ability of managing independently adjustable focal laws within the same frame-composing sequence of pulsing/receiving shots so every focal law may me executed with individually adjusted gain, time base, and other core settings providing:
Gain per Shot Correction for B-Scan
Angle Gain Compensation for S-Scan
True-to-Geometry imaging representing actual distribution of ultrasonic beams and true-to-location indication of defects in the cross-sectional view of the material

Frequency Domain - PA Modality: Ultrasonic Spectroscopy
For the significant number of inspection tasks the quality of the material may not be distinguished surely based on the traditional pulse echo technique: the deviation between the typical parameters of ultrasonic signals (amplitude, time of flight)
such as, for example, back wall echo, back scattered noise, etc is not sufficient for the grading of the material quality or GO / NO GO decisions. The frequency domain analysis applied to such signals became a very efficient tool for the
conventional modality based ultrasonic testing (UT), for example detection and sorting of the metals affected by HTHA (High Temperature Hydrogen Damage Attack), characterization of the composite parts and honeycomb panels, and the like. The quality
check and verification of the conventional ultrasonic probes according to EN 12668-2 and ASTM E 1065 involves the frequency domain signal analysis as well. Thus since almost 20 years ago all models of Sonotron NDT smart conventional UT flaw detectors
and the conventional channels of all Sonotron NDT PA instruments are featured with the frequency domain signal display based on the Fast Fourier Transform (FFT) implementation
The main problem of the conventional ultrasonic inspection based on the frequency domain signal analysis is the need in performing of the discrete point-by-point probing: due to the spectrum of the signal is very sensitive to the coupling
deviations the coupling should be stabilized for every new touch of the material surface with conventional probe making the scanning almost impossible so the speed of inspection is very low and practically there is no way to detect the boundary between
the normal and affected area of the material precisely
Since February, 2018 the frequency domain signal analysis became the standard feature of the PA Modality functioning for all portable Sonotron NDT instruments ISONIC 3510, ISONIC 2010, and
ISONIC 2009 UPA Scope and for the high speed automatic PA inspection platform ISONIC PA AUT. The FFT function is applicable to every focal law’s A-Scan obtained
at the calibration, inspection, and evaluation stage bringing the speed and reliability of the material characterization to the significantly higher level. For every frequency domain graph (FFT graph) the signal’s center frequency and bandpass
at the desired level are determined automatically and the corresponding mapping and real time imaging is available. The video below illustrates the typical application example related to the inspection of honeycomb panel with composite skin when
the FFT is applied to the back wall echo and the FD B-Scan (Frequency Doman B-Scan) image is formed for the entire PA probe coverage providing very clear pitch-size-resolution distinguishing between the different quality areas while the
regular B-Scan imaging doesn’t allow the same rapidness and simplicity of interpretation
The next video represents the PA Probe connected to the standard delay line, the front surface of which is free. The FFT is applied to every echo obtained through the reflection from the front surface of delay line whilst the firing / receiving aperture
consists of one element only: in such manner each element of the probe is verified rapidly by the echo amplitude, waveform, and frequency domain so the PA Probe verification document may be issued automatically in less than a minute since the PA probe’s
terminal is plugged in; the results of verification become compatible with the similar analysis performed for conventional probes
The PA probe verification report may be generated in a click then:
The videos below illustrate the rapid screening of the metal structure relating to the evaluation of the tempering quality. The same approach is applicable to the HTHA checking using compression and shear waves, casting nodularity
inspection, and the like:

True To Geometry Coverage and Imaging
True-to-Geometry Coverage and Imaging is the unique proprietary technology of Sonotron NDT, which is explained below based on an example related to the inspection of longitudinal weld
True-to-Geometry Coverage and Imaging Technology is based on the following principles:
the actual outer shape and dimensions of the material are entered into the instrument along with the important internal structure particulars and represented on the screen as the dimensioned drawing (sketch)
the image guided ultrasonic beam-tracing is performed by an operator over the said drawing through varying probe position on the scanning surface and manipulating beam coverage parameters virtually until the optimal scan plan is achieved
the needful calibration of ultrasonic PA pulser receiver and the correction settings corresponding to the designed scan plan are performed then with use of the appropriate calibration blocks
at last the sequence of focal laws providing the desired ultrasonic coverage of the material at the given placement of PA probe is formed; every focal law is characterized by the individually adjusted incidence angle, time base, gain, and DAC
the bulks of A-Scans representing every implemented focal law from the plurality defined by the scan plan are pushed into the focal law memory of the instrument and the image is composed in real time indicating the reflectors in their actual positions independently on the combination of beams providing their detection: the corresponding instrument file is available for download and playing with use of of the freely distributable ISONIC PA Office software package
The main adavantage of the True To Geometry Coverage and Imaging vs regualr sectorial / linear scan coverage is the extremely simple and quick interpretation of the results obtained by the ultrasonic PA flaw detector
The said advantage is illustrated by several videos below illustrating detection of several defects in the butt weld with asymmetrical bevel and in the fillet weld
Note: In order to accelerate the data stream the videos above are linked to the Youtube. In case the YouTube may not be accessed from your location please use the links below
EquPAS – the Equalized (Homogenized) PAUT Sensitivity approach is applicable for the inspections implemented by all portable and automatic ultrasonic PA flaw detectors and systems of Sonotron NDT’s
ISONIC series (ISONIC 3510, ISONIC 2010, ISONIC 2009 UPA Scope, ISONIC PA AUT)
covering the welds and parent material of all types and shapes, shafts and axles, raw materials (forging and casting), composites, etc tested with the use of linear, matrix and other types of PA probes
The EquPAS approach resolves the issue of inhomogeneous sensitivity over cross-section or volume of the material covered through implementing of the desired scan plan (either sectorial, linear, tandem, or 3D) by PA probe in
each position over the scanning trace. Prior to the inspection the instrument’s PA pulser receiver is calibrated in the same manner as the regular conventional ultrasonic flaw detector for one focal law selected from the plurality
to be implemented within the entire scan plan. Whilst implementing the sequence of pulsing receiving cycles following the scan plan each focal law is characterized by the individually settled focal point and time base; the sensitivity
is equalized within entire insonified section of the material through use of the independent mechanisms of Angle Gain Compensation (AGC, sectorial scan) or Gain per Shot Correction (GSC, linear, tandem, or 3D scan) and DAC/TCG acting
simultaneously thanks to the unique ability of ISONIC Series PA instruments: the DAC / TCG mechanism is used purely for compensating the dependency of echo amplitude on the material travel distance while the feature of
varying Gain per Focal Law voluntarily is utilized just for the forming of easy-reproducible AGC (or GSC) plan. Both the DAC / TCG and AGC (or GSC) plans are created with use of the same set of reference reflectors. The color
palette used for the imaging represents dB-to-DAC (TCG inactive) or the echo height (TCG active) value for each signal. As a result the same defect will be represented with the same color and evaluated accordingly independently
on it’s position in the insonified cross-section or volume of the material

FMC/TFM: Full Matrix Capture / Total Focusing Method for the
Data Acquisition, Processing and Imaging
Thanks to the fully parallel architecture the FMC/TFM protocols of data acquisition, processing and imaging are implementable in the ISONIC 2009 UPA-Scope instrument as well as in other ISONIC Series portable PA instruments such as
ISONIC 3510, ISONIC 2010.The FMC/TFM protocol is the standard feature for all suitable modes of operation
The exemplary videos below illustrate the unique ability of ISONIC series PA instruments allowing the on-line toggling between true-to-geometry (true-to-shape) sectorial scan coverage and imaging and FMC/TFM imaging for the inspection of:
butt welds
fillet welds
It is important that ISONIC 2009 UPA-Scope instrument is featured with 100% raw data storage for all inspections performed: for every focal law implemented with the use of some coverage
strategy, such as S-Scan, Linear Scan, etc or a combination of them the resulting A-Scan is formed as an outcome of superimposing with the corresponding phase shifts of
several of primary A-Scans produced by each element of the receiving aperture. As the primary A-Scans are stored into the raw data matrix the TFM image may be reconstructed
from the files created at any time in past using either S-Scan, Linear Scan coverage, etc or a combination of them:
The exemplary videos below illustrate the reconstruction of TFM image from the pure S-Scan files, which were obtained with no angle gain compensation and DAC (or TCG) normalization,
and comparison of TFM images with the EquPAS S-Scan coverage results: the EquPAS approach (Equalized Phased Array Inspection Sensitivity) is based on
the simultaneous use of two independent mechanisms equalizing the inspection sensitivity over entire insonified part of the material, namely Angle Gain Compensation and DAC (TCG) normalization.
All compared results were obtained with the same probe situated at the same position on the material:
As it is clear from the videos the TFM protocol and EquPAS S-Scan improve the coverage and sharpness of ultrasonic imaging significantly comparing to the pure S-Scan. The
detectability and imaging of the planar reflectors, which’s echo amplitudes strongly depend on the insonification direction have been improved very significantly as well
On the other hand comparing to FMC/TFM the EquPAS S-Scan allows using of smaller footprint probes; moreover the significantly less number of focal laws (pulsing/receiving cycles)
should be implemented in order to cover the same portion of the material so generally speaking the EquPAS S-Scan coverage allows scanning with the higher speed requiring the smaller area to be cleaned on the
surface of the material prior to the probe manipulation

with use of a pair of PA probes carrying up to 32 elements each. Use of 2 probes carrying more than 32 elements (up to 64) each is also possible provided the corresponding extension terminals involved
There is no external splitter required for the connecting of 2 PA probes to ISONIC 2009 UPA Scope
The welds inspected with use of the ISONIC DUET Technology may have either symmetrical or asymmetrical bevel
True to geometry coverage and imaging of the weld & HAZ volume is provided for each PA probe separately and in the overlap; each PA probe may implement a number of inosnifications simultaneously in the MULTIGROUP mode
For the first time ever the complimentary TOFD inspection with forming of up to 4 separate shots (depending on the material thickness) may be performed out of the same pair of PA probes:
This novel way of implementing TOFD shots extremely simplifies and lightens the structure of the scanning frame and it is already recognized by the international standard EN ISO 13588:2012 and a number of other national and industry codes;
alternatively the use of up to 4 additional pairs of regular TOFD probes connected to the conventional channels is possible
It is also provided the ability of simultaneous K-Pattern pitch-catch detection of the transversal cracks with use of conventional shear wave probes
Whilst scanning the weld from both sides along the fusion line the instrument performs:
100% raw data capturing
True-to-geometry cross-sectional imaging for each probe separately and in the overlap
Generating of the corresponding strip chart representing top view of the weld and HAZ
Coupling with the material is monitored for each PA probe separately and recorded into the corresponding strips
There is a number of scanners available for implementing of scanning with a pair of PA probes, such as, for example:
In order to prevent the quick damage of the cables of the PA probes carried by the scanner there are various extenders available,
which are connected to the instrument's PA probe terminals at one end and fitted into the scanner frame at the other so the PA probes cables are kept connected reliably

Tandem B-Scan
ISONIC 2009 UPA Scope is featured with the unique Tandem-B-Scan cross-sectional coverage and imaging technique, thanks to which
the reliable detection of the vertical and close to vertical planar defects in the welds, plates, tubes and vessels walls, rails, and the like is provided. 64-elements linear array probes are required for the implementation in compliance with international
standard
ISO 16826:2012
On entering the material thickness and the desired grid size the instrument determines the coverage strategy automatically: for every focal law to be implemented the focal points of the emitting and receiving aperture do match with each other and with the center of the corresponding grid cell
The independent gain per focal law adjustment equalizes the sensitivity over the whole covered cross-section of the material for the variety of implemented incidence angles and corresponding sound path lengths and wedge losses
For each focal law the time base of the A-Scan is settled automatically providing the appearance of possible defect echoes at 50%-position; the echo amplitudes are represented on the Tandem B-Scan by the corresponding color; placing cursor over the desired cell reproduces the corresponding ray trace and the A-Scan
ISONIC 2009 UPA Scope allows forming a group of tandem focal laws and implementing them simultaneously forming a strip chart - this mode of operation allows quick line-scanning of the narrow gap welds with zonal discrimination
DOWNLOAD AND PLAYBACK THE EXEMPLARY INSTRUMENTS FILES:
On completing the download the files should be extracted from the archive and played in the regular PC running under Win'XP, 7, 8, 10, 11 with use of the freely distributable ISONIC PA Office software package
C-Scan & 3D Imaging
For all types of the cross-sectional coverage ISONIC 2009 UPA Scope provides 3D Data Presentation - Top (C-Scan), Side, and End Projection Views through the line scanning either encoded or time-based with use of the linear array probes at rectangle to the elements count direction
There is a large number of various encoders and scanners available for the True-to-Location recording along the scanning line whilst scanning a wide variety of parts and materials - planar and circumferential butt welds, longitudinal seams, composites, raw materials, and the like. Some encoders and scanners for the line-scanning with use of one phased array probe are presented below. For scanning with a pair of phased array probe click on the DUET tab
This simple encoder is suitable for the quick manual scanning of the short sections (up to 1 meter) of the plates, planar butt welds, longitudinal welds, large OD circumefrential welds, and the like
The videos below illustrate 0-deg compression wave scaning of metallic and carbon fiber material - scanning, 100% raw data capturing, C-Scan and 3D imaging with the use of draw wire encoder SK 2001108 PA
The video below illustrates PA inspection of the stringers made of CRFP composite material - scanning, 100% raw data capturing, C-Scan and 3D imaging with the use of draw wire encoder SK 2001108 PA

The video below illustrates inspection of the planar butt weld scanned from both sides in several shots when the probe position was determined with the use of the draw wire encoder SK 2001108 PA
The robust encoder provides stable direction scanning with reliable positioning data. Phased array probe
is fitted into the corresponding probe holder connected to the the encoder. Each probe holder is quipped with the irrigation channel allowing reliable copling along the whole scanning trace
The enccoder 2001116 PA is suitable for the scanning above flat surfaces and pipes with OD of 50 mm and above
The videos below show the use of the encoder 2001116 PA for scanning along the fusion line of the planar and circumferential butt weld with PA probe
Bar encoder SK 2001112 PA
The use of the bar encoder SK 2001112 PA is very efficient for the inspection of long planar and quazi-planar welds, large plates, etc. The encoding element slides along the bar,
which should be placed along the desired scanning line as it is illustrated by the video below
The robust edencoder provides stable direction scanning with reliable positioning data. Phased array probe is fitted into the corresponding probe holder connected to the the encoder. Each probe holder is quipped with the irrigation channel allowing reliable copling along the whole scanning trace
During the line scanning every cross sectional view is recorded along with the complete sequence of raw data A-Scans it is composed of. C-Scan image is switcheable between distance (thickness or defects depth) and amplitude map
Very powerful off-line data analysis toolkit includes:
Playing back cross sectional views and A-Scans
Gain manipulation in ±6dB range for all recorded A-Scans followed by corresponding update of the cross-sectional, Top-, Side-, End- views

Crack Sizing
Internal Cracks
ISONIC 2009 UPA Scope allows detection and high precision sizing of the internal cracks inside the material based on the analysis of the longitudinal wave tip diffraction signals
Narrowing the region of interest shortens the time base for the A-Scans forming the cross-sectional coverage view allowing to distinguish between the upper and lower tip of the crack through 180-deg phase shift of the first half wave. This makes it possible applying of the TOFD technique principles whilst scanning with one probe only:
It is important that both the shear and the longitudinal wave cross-sectional coverage either S-Scan or B-Scan or a combination of them may be implemented simultaneously out of the same wedged linear array probe through running of the ISONIC PA MULTIGROUP utility. At last performing of the shear wave and longitudinal wave inspection with crack sizing in a single pass with one PA probe only became possible
Surface Breaking Cracks
Sizing of the surface-breaking cracks is implemented with use of 64-elements linear array probe. Separated emitting and receiving aperture with matching focal points produce and receive longitudinal wave signals in a sequence containing several pulsing-receiving cycles (focal laws).
The matching focal points of the emitting and receiving aperture are manipulated over the vertical line between the bottom and near surface of the material synchornously.
For each focal law the time base of the A-Scan is re-arranged automatically to provide appearance of every possible tip diffraction echo at 50% horizontal position. Recorded signal heights are represented on the Tip Diffraction B-Scan.
Placing mouse cursor over the desired cell of the Tip Diffraction B-Scan reproduces the corresponding A-Scan and the ray trace. For the detected tip diffraction signal the crack depth and the remaining material thickness are determined with high precision (~0.1 mm) through the triangulation routine
Example of the Tip Diffraction B-Scan obtained with the linear array probe placed above the material without (1) and with (2) a surface breaking crack: 3 - lateral wave (LW) signal mark; 4 - back wall (BW) echo mark; 5 - BW echo representation on the A-Scan; 6 - tip diffraction signal mark; 7 - tip diffraction signal appearance on the A-Scan; 8, 9 - precisely defined crack depth and remaining material thickness
The above noted principle and the procedure for sizing of surface breaking cracks are explained by the video below:

Defects Pattern Analysis
The pattern analysis for the weld imperfections found by pulse-echo technology may be performed by ISONIC 2009 UPA Scope instrument with the use of well-known Delta Technique.
Comparing to the quite bulky traditional embodimet for the Delta-Technique requiring the use of angle beam shear wave and zero-degree compression wave conventinal probes and two different instrument readings to be taken through implementation of
two different calibration sets the phased array technology based solution requires one wedged linear array probe only
In order to distinguish between the low risk volumetric and the critical sharp edge defects there are just two pulsing-receiving cycles (focal laws) focal laws implemented in sequence:
the first focal law provides emitting of the shear wave towards the discountinuity and receiving of the direct shear wave echo (masrked as 1)
the second focal law provides emitting of the shear wave towards the discountinuity and receiving of the diffracted longitudinal wave echo (marked as 2)
The instrument evaluates the above signals automatically and provides the digital readout (marked as 3) for so called KLS value, based on which the defect pattern is recognized
The instrument screen video illustrating the above described defect process of the defect pattern analysis through the comparing of the shear and longitudinal wave echoes is shown below:
The same process may be activated whilst peforming sectorial scan coverage of the material - the instrument screen video is below:

Matrix Arrays
Thanks to the fully parallel 64:64 architecture ISONIC 2009 UPA Scope provides volumetric coverage of the material with the use of
matrix array probes while the M x N active aperture (M, N > 2) may be composed of up to 64 elements. This allows controlling of both
the incidence angle and azimuth angle (beam swiveling angle) simultaneously as is illustrated by the videos below:
Compression wave inspection - matrix array probes with / without delay line
At the calibration stage the phased array pulser receiver is controlled through the operating surface of conventional ultrasonic flaw detector additionally equipped with the 3D ray-tracing guidance.
The 3D region of interest (ROI) is defined then.
The innovative live 3D-Scan L image is composed then at each position of the matrix array probe manipulated over the surface of the material
The principles of the True-to-Geometry 3D-Scan L coverage and live imaging are illustrated by the video below
The typical applications with the use 3D-Scan L coverage are:
• Detection of fatigue cracks in the solid bolts, rods, studs, etc
• Evaluation of spot welds
• Detection of defects in the forged and casted parts
For the shear wave weld inspection the matrix array probe should be coupled to the wedge, which's contact face width covers the desired range of the ultrasonic beam swiveling.
On entering the dimensions of the weld, probe position, and the beam swiveling limits the scanning along the fusion line may be implemented without typical mechanical skewing of the probe with no risk of missing unlikely situated defects.
The innovative live true-to-geometry 3D-Scan S image is formed through implementing of the sequence of focal laws providing the sectorial scan coverage combined with the swiveling and 100% raw data capturing at every lateral position of the probe
so at the postprocessing stage every A-Scan may be played back along with the corresponding Top-, Side-, and End- projection views
Shear wave 3D-Scan S screen for weld inspection: 1 - footprint of the wedge; 2 - limits for the beam swiveling; 3 - heat affected zone; 4 - weld metal; 5 - parent material adjacent to heat affected zone; 6 - defect (lack of fusion); 7 - A-Scan representing defect echo for the desired focal law
For the guided / surface wave inspection the matrix array probe should be coupled to the wedge, which's contact face width covers the desired range of the ultrasonic beam swiveling.
The incidence angle should be optimized for the desired modality then the lateral plane sectorial scan coverage is performed with 100% raw data capturing
Use of 2D Array (Dual Linear Array) Probes
ISONIC 2009 UPA Scope instrument allows the use of two-rows 2D Array probes (also known as DLA - Dual Linear Array probes) organized as up 2 X 32
The wedged dual linear array probes provide significant improving of the signal-to-noise ratio for some applications related to the compression wave inspection of coarse grain materials, for example stainless steel, CRA, and similar welds
For some inspection applications such as defects detection in the tube-to-tubesheet welds of the heat exchangers, corrosion detection, etc the dual linear array probes with the integrated delay lines may improve the near to surface resolution significantly.
ISONIC 2009 UPA Scope allows performing of both S-Scan and B-Scan coverage with use of dual linear array probes
C-Scan and B-Scan images for the 3 mm wall thickness tube with several small imperfections

Use of the Dual Matrix Array Probes (DMA)
ISONIC 2009 provides the ability of working the wedged DMA probes carrying a pair of matrix arrays comprising M x N elements each. DMA probes allow performing of the beam steering in the cross-sectional plane along with the
swiveling. This increases the flexibility of ultrasonic pulsing receiving thanks to the ability of controlling the depth of the common focal point for the emitting and receiving arrays electronically for the same wedge: in such manner the
signal-to-noise ratio may be optimized very efficiently. The control of the ultrasonic beams is illustrated by the short instrument screen video below:
ISONIC Series PA Instruments allow both true-to-geometry (true-to-shape) volume overlay sectorial scan (S-Scan) and FMC/TFM coverage and imaging with use of DMA probes:
The wedged DMA probes allow high performance inspection of the coarse grain welds made of CRA (Corrosion Resistant Alloys), Stainless Steel (Duplex, Super Duplex), and the like through running of
the EXPERT DMA or EXPERT_A DMA Inspection Software Applications:

PA UT (PAUT) Applications
Thanks to it's unique smart, flexible, and "teachable" architecture combined with the outstanding ultrasonic performance ISONIC 2009 UPA-Scope has been an ideal platform for the practically unlimited number of standard and customized inspection software applications, the number of which is increasing permanetly.Each application is dedicated to the resolving of the inspection tasks related to the certain class of parts and materials to be tested (the similar shape parts varying by the overall dimensions and the dimensions of particular segments).
Since the part to be inspected is outlined the scan plan is created just in few moments providing the True-to-Geometry Volume Corrected Coverage and imaging. This makes it possible to inspect complex geometry parts easily while the non Sonotron NDT made phased array instruments are practically not applicable
More details about PA AUT applications:
XY (Raster) Scanning
ISONIC 2009 UPA Scope supports the encoded XY-scanning and recording with PA probe for the variety of the inspection tasks
The typical inspection tasks such as corrosion mapping, detection of the impact damages in in the coposite panels, flaw detection in various materials, and the like are resolved through to the compression wave inspection with use of linear- or 2D-array probes with / without detachable delay lines, etc.
The XY-Scan software application is required for the said inspections; use of various XY-scanners from the simplest Draw-Wire to the high precision is supported
There is 100%-raw data capturing performed while scanning so the inspection results may be presented in the form of the Amplitude- or Depth C-Scan (switcheable), 3D image, various slices either longitudinal, transversal or horizontal, and the like; every cross-sectional view corresponding to the desired probe position and every A-Scan may be played back and evaluated. The data noted above may be reproduced at the various Gain and Gate settings:
The movies below illustrate the examples of simplest embodiment for the encoded XY-scanning, imaging, and recording with use of PA probe
The movie below illustrates some features related to the postprocessing of the XY-Scan data

ISONIC Roverscan
The ISONIC RoverScan technique allows inspecting of the complex geometry parts such as turbine blades, pipe-to-pipe welds, and the like through XY-scanning
In such parts the cross-sectional shape varies along the scanning trace so
the true-to-position material-shape-accommodation of the cross-sectional coverage focal laws is performed by ISONIC 2009 UPA Scope in real time whilst manipulating PA probe over them; in other
words: for every point of the probe trace the focal laws are accommodated dynamically in order to provide the complete true-to-geometry cross sectional coverage
To follow the ISONIC Roverscan technique the 3D-model (CAD, Parasolid, etc) of the part to be tested is used by the instrument in the following way:
At the pre-inspection stage the 3D-model of the part is “implanted” into the instrument's memory as a template
At the scanning stage the coordinates of the PA probe manipulated over the part are taken by the instrument through the appropriate encoding means and the accommodation of the focal laws is performed automatically in real time at every point of the probe trace:
the corresponding true-to-location cross-sectional scan plan (ray tracing) is generated and implemented so the cross-section of the part under the probe is “filled” with the ultrasonic beams accordingly providing the needful coverage
the true-to-geometry imaging of the cross-section is provided so on receiving an echo from an obstacle either geometry or internal discontinuity (imperfection) the reflector is imaged in its real position through settling of the appropriate mark on the image
all cross-sectional views obtained during the scanning are pushed into the 3D-template in the instrument’s memory and stored along with the corresponding raw data (A-Scans) sets
On completion of the scanning the 3D-image of the part with the imperfections found is generated
Interface Echo Start - PA Modality
Interface echo (IE) start of the A-Scan time base is a standard function of ISONIC 2009 UPA-Scope and all other PA instruments of ISONIC series
(ISONIC 3510, ISONIC 2010, ISONIC PA AUT) whilst utilizing PA modality. On switching to the B-Scan coverage and imaging the IE start function is applied to every A-Scan
within entire sequence of the focal laws implemented provided the ability of performing either immersion (IUT) or quasi-immersion with use of water filled array probes with flexible silicon tire as
it is illustrated by the video below:
The exemplary videos related to the PA IUT (Phased Array Immersion Ultrasonic Testing) are present here:

Wedge Verification
Wedged PA probes with flat and curvature contoured contact face are widely used for the shear-, compression-, short range guided wave inspection, and the like
In order to provide precise forming of ultrasonic beams and correct coverage of the material as well as accurate imaging and evaluation of imperfections it is absolutely necessary to enter
parameters of the wedges into the instrument correctly and verify them on regular basis when using because the actual values of wedge parameters may deviate from their nominals:
Wedge Angle depends on the degree of wearing
Ultrasound Velocity in the wedge depends on the ambient temperature and temperature of the part to be inspected, degree of ageing of polymer material it is manufactured of, etc
Position of the First Element above the surface of the material depends on the degree of wearing as well
For that purpose ISONIC 2009 UPA-Scope as well as all other ISONIC series PA instruments such as ISONIC 3510, ISONIC 2010,
and ISONIC PA AUT are featured with the simply implemented precise image guided routine, which is explained by the exemplary videos below recorded for the wedges with
Flat contact face
CU-contoured contact face for the longitudinal insonification of tubulars (looking-axially-inspections)
CUC-contoured contact face for the circumferential insonification of tubulars (looking-circumferentially-inspections)
On completion of the verification / correction of the wedge parameters through just shown quick and simple procedures the precision of the material coverage (scan plan), detection, imaging,
and evaluation may be checked on the suitable performance demonstration block in a touch
The most precise results are well achievable then for the real inspections

Testing Integrity
Along with recording and displaying of the inspection data characterizing the quality of the material the on-line monitoring of scanning performance is provided. The perceptible operative indication is submitted through progressive filling
of the Scanning Performance Strip with green (normal process), red (coupling loss – total data loss), and violet (over-speed – partial data loss) colors urging the operator to rescan the imperfectly passed segments. The scanning performance
data is recorded synchronously with the inspection data and stored into the same file
100% raw data capturing and homogenized inspection sensitivity over entire cross-section (volume) of the material as determined by the scan plan and the scanning performance data monitored on-line and recorded at parallel with the inspection
results bring testing integrity to the highest level
The video below illustrates the scanning process for the inspection of planar butt weld with 100% raw data capturing and recording and imaging of inspection data along with filling of Scanning Performance Strip:
Quantitative evaluation and reporting of scanning integrity may be obtained immediately on the inspection site for each inspected section of the material or at postprocessing stage as it is illustrated by two exemplary videos below
captured when using linear array and dual matrix array (DMA) probes:
In-line with newly appearing standards and norms setting the quality of PA testing the scanning integrity report reflects:
the actually performed scanned length along with corresponding time consumption and average scanning speed
overall length and percentage of coupling loss segments
overall length and percentage of over speed segments

Conventional UT and TOFD Modalities
For the single conventional channel operation ISONIC 2009 UPA Scope provides:
Fully featured A-Scan inspection
Line scanning recording and imaging of the following types:
Thickness B-Scan;
True-to-Geometry flaw detection B-Scan for angle beam and straight beam probes;
Flaw detection CB-Scan for the guided, surface, and shear wave probes inspections;
High resolution flaw detection B-Scan;
Fully featured TOFDinspection
Comprehensive postprocessing toolkit
This fully corresponds to the scope of functionality provided by the very popular Sonotron NDT's portable ultrasonic flaw detector and recorder ISONIC 2005 / ISONIC STAR / ISONIC 2020
ISONIC 2009 UPA Scope instruments equipped with 8 or 16 channels additionally provide the multi-channel strip chart recording with forming all known types of strips such as:
B-Scan (Map);
PE (Amplitude + Time of Flight);
TOFD;
Coupling
The comprehensive off-line analysis and data reporting toolkit for all kinds of data captured using conventional UT and TOFD modalities is built-in
This fully corresponds to the scope of functionality provided by the very well known Sonotron NDT's portable multi-channel ultrasonic flaw detector and recorder ISONIC 2008
In the ISONIC 2009 UPA Scope instrument conventional channels and phased array channels may be used simultaneously. For example the Sonotron NDT's DUET_M technology supposes the use of a pair of wedged linear array probes for the multi-group inspection of welds from both sides and, at parallel, the use of:
up to 4 additional pairs of regular TOFD probes;
up to 2 pairs of conventional angle beam shear wave probes for the K-Pattern pitch-catch detection of the transversal cracks
Utilizing PA Channels for Driving Arrays of Conventional Probes
For a variety of practical inspection tasks use of arrays composed out of a number conventional probes is more efficient comparing to PA modality. Use of 16-, 32-, 64- or more channels high productivity automatic platforms may be justified just for
the factories or other sites with continuously running manufacturing process. Use of portable stand-alone multi-channel instrument is more cost effective but purchasing of such units may be not justified by every small / medium size inspection
companies just for the resolving of occasionally occurring inspection projects
Anyway, the owner of ISONIC Series portable instrument such as ISONIC 2009 UPA Scope, ISONIC 3510, ISONIC 2010 may resolve various inspection
tasks using arrays of conventional probes utilizing PA channels easily whilst connecting conventional probes to PA channels using the spliier box SA 36895870:

UT over IP - Remote Control and Data Acquisition
Thanks to the Client – Server software architecture ISONIC 2009 UPA Scope may be controlled remotely from a regular PC running under Win’XP, 7, 8, 10, 11. There is no need in the special software for that purpose, just download and install in the PC the same software as used in the instrument
The software installed in the PC should be of the same release as the software running in the ISONIC 2009 UPA Scope and correspond to the instrument model
Installing the Instrument Software in the PC
Upon started the installation routine generates the dialogue as below on the PC screen:
It is necessary to check Install client only and uncheck Run on windows startup option then to click on Install button. Further actions are taken by the installation routine automatically
Controlling the Instrument from the PC
The instrument and the computer should be connected to the same LAN or Wi-Fi and obtain the IPs automatically. The initial Startup menu (Start Screen) appearing upon powering the instrument on and booting up completed
should be kept on the unit's screen at the time of establishing the remote connection and control. In the computer the same software should be launched: on appearing of the Startup menu it is necessary to select the instrument
to be controlled from the list of the available Idle units:
Once the connection is established ISONIC 2009 UPA Scope unit enters into the slave mode being connected to the probes and encoder and running the just the server routine while the computer performs full control of the instrument,
data acquisition, processing, and storage on the local drives through running of the client software in the same manner as the instrument does when operating autonomously
