Abstract

We recently developed and tested a prototype ultrasonic nondestructive test instrument that produces unipolar stress pulses in pulse-echo mode. The use of unipolar pulses instead of bipolar pulses offers significant increases in bandwidth[1]. This new instrument should be useful in material processing, characterization and flaw detection and sizing applications over a range of flaw radii which are not accessible using conventional pulse/echo equipment[2].
