Abstract
A technique for testing residual stresses in the rims of solid-rolled wagon wheels with an ultrasonic method using the electromagnetic-acoustic method of exciting-receiving acoustic signals is described. An engineering solution that makes it possible to obtain trains of bottom signals using electromagnetic-acoustic transducers is proposed. The results from determining residual stresses in new and used wagon wheels are presented.
