PA UT (PAUT): Butt and Transit Welds - Asymmetyrical Bevel

ISONIC EXPERT_A software application was created for the inspection of planar and circumferential butt welds with symmetrical and asymmetrical bevel, unbeveled, misaligned, and the like with use of wedged linear array probes situated on the parent material

ISONIC EXPERT TRANSIT software application was created for the inspection of transition welds with symmetrical and asymmetrical bevel, unbeveled, misaligned, inclined welded parts, and the like with use of wedged linear array probes situated on the parent material



Both inspection software options are available for the ISONIC 3510T / ISONIC 3510, ISONIC 2010, and ISONIC 2009 UPA Scope instruments and featured with:
  • True-To-Geometry Weld Overlay Volume Corrected Imaging - Cross Sectional and Top (C-Scan)- / Side- / End- View and 3D
  • Sector-Scan Cross Sectional Coverage
  • Intuitive Image Guided PA Pulser Receiver with Beam Forming View
  • DAC / TCG Normalization
  • Built-In Weld Geometry Editor and Ray Tracer - Scanning Pattern Design
  • Automatic Curvature Correction for the wedges with contoured contact face (FILLET CU)
  • Independent on TCG Angle Gain Compensation / Gain Per Focal Law Correction
  • Automatic Coupling Monitor
  • Automatic Scanning Integrity Monitor
  • Detection of the defects in the parent material simultaneously with weld inspection
  • Encoded and Time based C-Scan
  • 100% Raw Data Capturing
  • FMC/TFM Protocol for the data acquisition and imaging
  • Automatic Defects Alarming Upon C-Scan Acquisition Completed
  • Automatic Creation of Editable Defects List
  • Automatic Creating of Scanning Integrity Report Upon C-Scan Acquisition Completed
  • Comprehensive Postrpocessing Toolkit Including:
    • Recovery and Evaluation of Captured A-Scans from the Recorded Cross Sectional Views (Sector Scan) and C-Scans
    • Recovery of the Cross Sectional Views from the Recorded C-Scan data
    • Converting Recorded C-Scans or their Segments into 3D Images
    • Off-Line Gain Manipulation
    • Off-Line DAC to TCG / TCG to DAC toggling for all types of stored files (A-Scans, cross-sectional views, C-Scans, etc)
    • Off-Line DAC Normalization of the Recorded Images / DAC Evaluation
    • Off-Line editing of Angle Gain Compensation / Gain per Shot Correction applied to the stored the Cross-sectional Views / C-Scan data
    • Numerous Filtering / Reject Options ( by Geometry / Position / By Amplitude db-toDAC / etc ) and Regeneration of the Corresponding of Editable Defects List and Storing it into a Separate File
    • Defects Sizing
    • Automatic Creation of Defect List and Storing it Into a Separate File
    • Automatic Creating of Scanning Integrity Report
    • Automatic creating of inspection reports - hard copy / PDF File

The movies below illustrate detection of the vertical crack and lack of fusion in the butt weld with asymmetrical bevel with use of the ISONIC 3510T / ISONIC 3510 instrument

ISONIC 3510T / ISONIC 3510 provide the operator with the ability of simple toggling between the S-Scan and live FMC/TFM coverage and imaging at any moment whilst scanning. The same ability is present in the ISONIC 2010 units manufactured after April 30, 2017 and ISONIC 2009 UPA Scope units manufactured after May 31, 2017. Availability of using both complimentary coverage strategies such as True-To-Geometry S-Scan and live FMC/TFM in the same instrument at the same time further improves the versatility of use, the data interpretation, and the reliability of ultrasonic inspections:

At last the video below illustrates the good suitability of ISONIC EXPERT_A software application for the inspection of special complex geometry welds such as train coupler joints, and the like:

Rapid detection of fatigue cracks in the reducer welds with the use of ISONIC EXPERT TRANSIT software application is illustrated by the video below:
