Abstract

In any ultrasonic test the shape and roughness of the test surface is of decisive importance. On the one hand these factors often limit the sensitivity of the method applied, making it necessary to first prepare the surface; on the other they have an important influence on the wear of the probes used for continuous and routine tests if in direct contact with the specimen. The surface conditions, therefore, greatly influence the economics of testing.
