PA UT (PAUT): Fillet / TKY Welds

ISONIC EXPERT FILLET software application was created for the inspection of fillet, Tee- , TKY- welds, and the like, with use of wedged linear array probes situated on the flange or web surface. It is also well suitable for the inspection of the pipe repair sleeve circumferential welds with the skewed-fillet-like cross section

ISONIC EXPERT FILLET CU software application was created for the inspection of fillet, Tee- , TKY- welds, and the like with use of wedged linear array probes situated on the curved flange surface

Both software options are available for the ISONIC 3510, ISONIC 2010, and ISONIC 2009 UPA Scope instruments and featured with:
  • Built-In Weld Geometry Editor and Ray Tracer - Scanning Pattern (Scan Plan) Design
  • Intuitive Image Guided PA Pulser Receiver with Beam Forming View
  • Automatic Curvature Correction for the wedges with contoured contact face (FILLET CU)
  • True-To-Geometry Cross-Sectional Coverage and line scanning along the fusion line either encoded or time based
  • "On-the-fly" True-To-Geometry Weld Overlay Volume Corrected Imaging:
    • Cross Sectional Slices
    • Top (C-Scan) View
    • Side View
    • End View
    • 3D View
  • DAC / TCG Data / Image Normalization
  • Independent on TCG Angle Gain Compensation / Gain Per Focal Law Correction
  • Automatic Coupling Monitor
  • 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
  • Comprehensive Postrpocessing Toolkit Including:
    • Recovery and Evaluation of the Captured A-Scans from the Recorded Cross Sectional Views and C-Scans
    • Recovery of the Cross Sectional Views from the Recorded C-Scans
    • Converting Recorded C-Scans or their Segments into 3D Images
    • Off-Line Gain Manipulation
    • Off-Line DAC Normalization of the Recorded Images / DAC Evaluation
    • 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 creating of inspection reports - hard copy / PDF File

The movies below illustrate inspection of fillet welds with use of the ISONIC 3510 instrument providing the ability of either

  • toggling between the True-to-Geometry (True-to-Shape) S-Scan and live FMC/TFM coverage and imaging at any moment whilst scanning
  • performing both coverage strategies at parallel along with recording and displaying the live images
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 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

Some other illustrative videos are below

The videos below demonstrate the ability of ISONIC series PA instruments to generate TFM images for the defects in the fillet welds off-line out of earlier stored True-To-Geometry S-Scan data files; this is possible thanks to 100% raw data capturing when the primary A-Scans for each element of the receiving aperture are recorded for each implemented focal law:
