APPLICATIONS OF FREQUENCY ANALYSIS IN ULTRASONIC TESTING

Applications and theory associated with control of ultrasonic test variables, identifying and sizing flaws, and improving resolution both for thickness measurements and detection of near-surface flaws are presented. The advantages of spectral analysis techniques in reproducibility, precision, simplicity, and evaluation of importance of discontinuities in materials are discussed. Examples of discontinuity spectra for welds are shown in graphic form with the corresponding oscillographs.
