FLAW-SIZE MEASUREMENT IN A WELD SAMPLE BY ULTRASONIC FREQUENCY ANALYSIS

An ultrasonic frequency analysis technique has been developed and applied to characterize flaws in an 8 in. (203 mm) thick heavy-section steel weld specimen. The technique applies a multitransducer system. The spectrum of the received broad-band signal is frequency analyzed at two different receivers for each of the flaws. From the two spectra, the size and orientation of the flaw are determined by the use of an analytic model proposed earlier. /Author/
