Transverse Cracks Detection and Sizing on a Sheet Inner Surface

A. V. Semerenko

The economically priced Crack Detection and Sizing (CDS) Wedges series, Panametrics-NDT™, de­signed for use in the so-called “30-70-70” technique. This wedge creates a 70 degree longitudinal wave as well as a direct shear wave at approximately 30 degrees in steel. This wedge also creates an ID connected creeping wave for detection of small ID flaws.
