Abstract
An analysis of publications on this topic showed an increase in the researchers’ interest in in-depth study of the possibilities of magnetostrictive effects as a basis for the development of new methods of ultrasonic non-destructive testing (UNT). It was noted that a new promising direction of research is the creation of UNT methods and tools based on small-aperture magnetostrictive transducers (MST). Such transducers allow testing objects of complex geometry, in dry contact with MST and in a wide range of temperatures of control objects. The article is devoted to the development of UNT tools using MST, the action of which is based on the Joule and Villari effects, and the study of the possibilities of their application in UNT problems. In particular, the features of MST designs, their characteristics, and the peculiarities of signal formation of the emitting and receiving transducers are considered. For experimental tests, an original UNT system with a signal frequency of 0.5 MHz was used, which made it possible to evaluate the capabilities of the developed UNT method on test samples, which were metal plates with defects in the form of holes of different diameters, and by testing defects in welded joints.
