Abstract

Conventional pulse-echo ultrasonic inspection uses the ratio of the signal from a crack-like defect to the signal from a reference reflector as one factor which determines whether the flaw merits reporting, further sizing, and, possibly, removal. Two reference reflectors are in common use: a side-drilled hole and a flat-bottomed hole.
