Description

Pulse-echo reflection techniques are used for ultrasonic flaw detection in most commercial instruments [1,2]. The ultrasonic wave, generated by a piezoelectric transducer coupled to the test specimen, propagates through the material and part of its energy is reflected when it encounters a non-homogeneity or discontinuity in its path, while the remainder is reflected by the back surface of the test specimen. The flaw echo contains information regarding the material discontinuity that the ultrasonic wave has encountered in its path.
