Effect of Shock Loading with Ultrasound on the Structure and Properties of the Metal of Welds and Products

Acoustic and x-ray diffraction studies were made of the effect of ultrasonic shock treatment on the stress state of a welded plate of steel St3sp and hard-faced rolling-mill rolls of steels 24KhNM1 and 12KhNM1. It was determined that treatment with ultrasonic pulses has a positive effet on the quality of metal products and their welds.
