Abstract

Theoretical and experimental studies of the mirror-shadow ultrasonic testing of railheads using the electromagnetic-acoustic (EMA) method have been performed, and schemes and facilities for this technique have been developed. The main factors affecting the results of tests are determined. The tolerable limits of the changes in the tested parameters are established. It has been shown experimentally that the EMA method is highly sensitive in detecting flaws of technological origin in the railhead bulk, which do not produce echo signals with sufficiently high amplitudes.
