Abstract
The dynamic progress and residual distortion of out-of-plane of aluminum alloy 5A12 were investigated under different welding conditions of TIG welding. The dynamic out-of-plane distortion was measured by self-developed distortion measuring system. Out-of-plane distortion mechanism and the effecting parameters on distortion process were analyzed, and the effect of plate thickness and welding heat input on distortion was discussed. The results show that the plate thickness and welding heat input have great effect on the dynamic process and residual distortion of out-of-plane. The residual distortion of out-of-plane can be divided into three types including arch, buckling and bowling distortion.
