Abstract

Conventional ultrasonic C-scanning for detection and characterization of material defects has limitations because it provides only an overall planar view of the damage without accurate definition of the size and location of flaws. Hence, a three-dimensional reconstruction from the digitized ultrasonic pulse-echo waveform database was developed for full volume evaluation of damage [1].
