Abstract

To solve the problem of quality control in rolled metal (localization of technological defects, determination of differences in thickness), various methods of nondestructive control are made use of, including, rather widely, acoustic methods. The main demerit of these methods is the necessity of a good (acoustic) contact between the irradiating and receiving surfaces of the piezoconverter, on the one hand, and the surface of the object under examination, on the other hand. Such contact is in a number of cases, hard to ensure, and any control of objects at high temperatures is practically impossible.
