Description

Ultrasonic pulse-echo techniques are widely used for detection and sizing of defects. However, studies over recent years have shown that the detection and sizing capability of many of the widely accepted ultrasonic techniques do not provide accuracy required to assure safety, reliability or maintainability. While certain types and orientations of defects can be detected, others may go undetected. Even after detection, studies have shown that the ability to size defects is far from accurate. [1,2,3]
