Abstract

This article describes the description and the results of experimental work to confirm the efficiency of the method for removing residual mechanical stresses in welded joints of NPP pipelines after they have been performed by ultrasonic hardening. Also, based on the results of the experiment, it is proposed to develop an automated device, the work of which is based on the proposed method.
