CDS wedges are designed to generate both a 30 degree shear wave and a 70 degree longitudinal wave in steel for sizing ID connected cracking by means of the 30-70-70 technique.
The 30-70-70 crack detection technique uses a single element transducer with a CDS wedge for detection and sizing of ID connected cracks. This technique uses a combination of three waves for sizing flaws of different depths.
Based on the presence or absence of these three waves, both detection and sizing of ID connected cracks is possible. |
CDS Wedges are used in the "30-70-70" technique for crack detection and sizing. They are compatible with our replaceable miniature screw-in angle beam transducers, making them an economical alternative to other commercially available products.
