Abstract
We describe promising directions in the development of the eddy-current method for the flaw detection of structural elements. We show the possibilities of subsurface flaw location based on the use of low working frequencies and quantitative control with the identification and evaluation of parameters of the found defects. The possibilities of applying high working frequencies for the control of thin surface layers of an article and low-conducting materials are described. We present also the possibilities of new eddy-current converters and flaw detectors as well as testing technologies developed on the basis of their application. Finally, we describe new methods of information processing, in particular, the two-dimensional visualization of testing results.
