| Abstract: | Ultrasonic peening treatment is a new method that can improve residual stress of welded joints. In this paper, the ultrasonic peening treatment equipment was studied and developed. It was with the functions of automatic frequency-tracking and automatic output power-adjusting. With the equipment, the verification tests of ultrasonic peening treatment effectiveness on the Q235, HG70 steel were carried out. Preliminary results indicate that the equipment can satisfy the engineering requirement. Ultrasonic peening treatment can effectively improve the residual stress of welded joints. |
