NDT & Inspection RTD IWEX The major advantages of RTD IWEX Rotoscan 3D are: • Straightforward interpretation that is less dependent on operator skills and calibration blocks; • Reliable detection and accurate sizing, less dependent on defect orientation than existing UT techniques; • The IWEX image is directly linked to defect properties.; • Improvements have been introduced that allow for imaging of defects in the near surface, in a weld with cap and root or perpendicular to the surface; • Defects with various orientations are imaged by combining both direct insonification and indirect measurements via the back wall. • Better and easier means of defect detection and characterization will ultimately lead to less repair and maintenance costs. A new way of UT defect detection and presentation. Inverse Wave field EXtrapolation (IWEX) is an emerging novel method to construct images ofdefects in (girth) welds from ultrasonic array data.The ultrasonic images show a great potential in both defect detection, sizing, positioning and characterization, combined with a simplified 2D and 3D presentation of inspection results.

RTD IWEX

The major advantages of RTD IWEX Rotoscan 3D are:

• Straightforwardinterpretationthatislessdependentonoperatorskillsandcalibrationblocks;

• Reliabledetectionandaccuratesizing,lessdependentondefectorientationthanexistingUTtechniques;

• TheIWEXimageisdirectlylinkedtodefectproperties.;

• Improvementshavebeenintroducedthatallowforimagingofdefectsinthenearsurface,inaweldwithcapand
