PA UT (PAUT): VLFS CU - Vertical Line Focusing Scanning and Imaging of Tubular Parts and Materials

ISONIC VLFS CU allows performing of the Vertical Line Focusing Scanning and Imaging of the tubular parts and materials

The typical applications relate to theinspection of:
    • narrow gap heavy thickness longitudinal welds
    • ERW and EBW longitudinal welds in tubes
    • seamless tubes
    • etc

  • True-To-Geometry Cross-Sectional Coverage (sectorial and / or linear) and line scanning along the desired line (for example, fusion line) either encoded or time based
  • "On-the-fly" True-To-Geometry Whole Volume / Region of Interest (ROI) Overlay Volume Corrected Imaging:
    • Cross Sectional Slices
    • Top (C-Scan) View - Unfolded
    • Side View
    • End View
    • 3D View
  • DAC / TCG Data / Image Normalization
  • Independent on TCG Angle Gain Compensation / Gain Per Focal Law Correction
  • Automatic detecting of the maximal echo A-Scan among the plurarity implemented for providing of the cross-sectional material coverage
  • Automatic Coupling Monitor

  • 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 video below illustrates the ability of ISONIC series PA instruments to generate TFM images for the defects in the long seams of the "seamless" pipes and perform the sizing of the reflectors with high precision; the said ability is provided thanks to the 100% raw data capturing when the primary A-Scans for each element of the receiving aperture have been stored for each implemented focal law:
