Abstract:
The analysis of information sources in the field of sensitivity of ultrasonic non-destructive testing of metal products by instruments and devices with electromagnetic-acoustic transducers was performed. It is established that, in comparison to the traditional contact testing method in its field of application: the testing of metals without special surface preparation, automatic and automated testing with high productivity, EMA testing has significant advantages. In many cases, the sensitivity of flaw detection using EMAT is not inferior to the traditional contact method, and in some cases even exceeds it. 17 Re., 5 Tabl.
Keywords: electromagnetic-acoustic control, metalware, testing sensitivity, detectability of defects, determination of physical-mechanical characteristics of metal products, thickness measurement.
