摘要

针对6082-T6铝合金三铣平面螺纹锥形针FSW进行工艺研究及优化，基于Hexagonal Design响应面法，建立数学模型并进行工艺参数的优化。工艺参数对接头拉伸性能有明显的影响，其中旋转速度对其性能的影响更为显著。在保证焊缝无缺陷条件下，适当提高旋转速度和焊接速度，可得到性能最优的焊接接头，最佳工艺参数为旋转速度850 r/min，焊接速度650 mm/min，此时三铣平面螺纹锥形针可有效促进材料塑性流动，焊缝内部成形好且无明显缺陷，接头的抗拉强度达到257.29 MPa，断后伸长率达10.68%。

Abstract

The study and optimization of FSW process for 6082-T6 aluminum alloy via triple milling plane thread conical needle was carried out. Based on the Hexagonal Design response surface method, the mathematical model was established and the process parameters were optimized. The tensile properties of the welded joints were obvious effected by the process parameters, especially the rotation speed. The best performances of the welded no defect joints were obtained by increasing the rotation speed and welding speed appropriately. The optimal technological parameters were rotation speed 850 rpm and welding speed 650 mm/min. The triple milling plane thread conical needle can effectively promote the plastic flow of the material. The weld was well formed without obvious defects. The tensile strength of the joint reached 257.29 MPa with the elongation of 10.68%.
