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

The typical applications relate to theinspection of:

    • narrow gap heavy thickness longitudinal welds
    • ER longitudinal welds in tubes
    • seamless tubes
    • etc

This inspection software option is available for the ISONIC 3510ISONIC 2010, and ISONIC 2009 UPA Scope instruments and featured with:

  • Built-In Ray Tracer - Scanning Pattern (Scan Plan) Design
  • Intuitive Image Guided PA Pulser Receiver with Beam Forming View
  • True-To-Geometry Whole Volume / Region of INterest (ROI) Overlay Volume Corrected Imaging - Cross Sectional and Top (C-Scan)- / Side- / End- View and 3D through Sector-Scan Cross Sectional Coverage and line scanning along the desired line (for example, fusion line) either encoded or time based
  • 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
  • 100% Raw Data Capturing
  • 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 (Sector Scan) 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

Compression wave cross-sectional coverage of the material with use of VLFS strategy combined with the RF A-Scan capturing ensures detection and distinguishing of the vertically oriented cracks and other planar sharp edges discountinuities. The said innovative modality also known as a reverse TOFD technique is based on the analysis of tip diffraction echoes providing high precision evaluation of the defects position and dimensions with use of a single probe / one side access only
