| 摘 要： | 通过采用针对同种铝合金点焊接头界面的铜箔示踪方法,对2 mm厚6061-T6铝板进行搅拌摩擦点焊工艺优化试验,设定点焊界面畸变几何特征参量,重点研究在不同轴肩下压量的条件下,接头界面畸变形貌特征的演变规律及其对接头力学性能的影响.结果表明,相较于其它焊接工艺变量而言,搅拌头轴肩下压量的变化对接头界面畸变形貌的影响最为明显;增加轴肩下压量可基本消除点焊接头界面翘曲,并能够拓宽有效连接区域,提高接头抗剪切性能.

| Abstract: | Base on the copper foil tracer method,the parameters for friction stir spot welding 2mm-thick 6061-T6 aluminum alloy sheet was optimized.The influence of different plunge depths on the characteristic evolution and mechanical properties of joint interface was investigated by setting the geometric characteristic parameters of interface distortion.The experimental results reveal that the effect of plunge depth on the interface distortion morphology was most significant,comparing to other welding parameters.Increasing the plunge depth could almost eliminate the interface warping,increase the width of effective bonded area and shear strength of the joint. |
