Abstract

Twenty-three flaw geometries have been fabricated by way of side-drilled and electro-discharge machining in steel test blocks. The flaw types consisted of smooth cylindrical and elliptical, and sharp type rectangular and triangular in both singular flaw and cluster situations. The goal of this study was to separate the 23 test flaws into as many groups as possible on the basis of ultrasonic data acquisition and pattern recognition - perhaps 23 - while serving as a feasibility study for extensions into the real flaw inspection and classification situation. Ultrasonic data were obtained in a scattering mode with a fixed position angle beam transducer.
