Abstract of the Disclosure, An incident beam of ultrasonic waves is directed onto the surface of a test piece for nondestructive testing and especially for measuring the case-hardening depth of steels. The method consists in subjecting the beam to a uniform displacement at a constant angle of incidence in, detecting the ultrasonic waves back-scattered from the test piece, then in visualizing on a receiver the energies of the successive waves which are back-scattered during at least a predetermined fraction of the beam travel. -1-
