摘要:

A testing method is described for the depth measurement of defects that can occur in CANDU nuclear reactor pressure tubes. Experiments are reported which use immersion transducers, to study the interaction of shear waves with both artificial and real defects. A hybrid system, based on both time and amplitude measurements, is proposed for the estimation of defect depth.
