| Abstract: | The processes for eliminating the welding residual stress of LC52 Al alloy were researched. The characteristics of three kinds of different processes for eliminating the welding residual stress of Al alloys, including heat-aging, VSR and ultrasonic aging, were analyzed and compared. The results show that a reasonable VSR process can eliminate effectively the welding residual stress of heat-treating aging-hardened Al alloys. The welding residual stress of Al alloy structural parts were obviously reduced and homogenized using zsx-05 VSR device, the reducing rate was above 40%. |
