摘要：

A new method named rotating extrusion(RE) is pressented in this paper, which is used to control welding residual distortion of thin-plate weldments. The basic principle of RE and its mechanism of mitigating welding residual distortion are introduced. The effectiveness of rotating extrusion and relationship between the control effect of welding distortion and technical parameters are studied based on the device remodeled from common milling machine. The experimental results show that RE method can reduce residual distortion of weldments made of 2A12T4 aluminum alloy thin plates to below 3% of that of conventional weldments when proper technical parameters are chosen. The control effect of welding residual distortion is related to some technical parameters. Keeping other parameters unchanged, the slower travel speed of results in the weldments, the better control effect of residual distortion. Furthermore, only when metals both in and around the weld are extruded by the extrusion head can a good control effect of welding residual distortion be attained.
