摘　　要：针对车身用1.5 mm的AA6061-T6铝合金薄板,研究采用透胶胶焊法和毛细作用胶焊法两种工艺对PFSSW-胶点焊接头拉剪性能的影响。通过热力耦合法对搭接区域温度场进行分析,然后对比不同工艺顺序接头的拉剪性能及断裂模式。结果表明:相比PFSSW和透胶胶焊法,毛细作用胶焊法能够明显提升铝薄板接头的拉剪性能。本文为车身铝薄板及其他胶焊接头的连接工艺提供了方法支持。For the 1.5 mm thick AA6061-T6 aluminum alloy sheet for bodywork,the effect of twoprocesses on the tensile shear performance of PFSSW-glued spot welding joints was studied using thepenetrating glue welding method and the capillary action glue welding method.The temperature field in thelap region was analyzed by the thermal coupling method,and then the tensile shear properties and fracturemodes of the joints using different process sequences were compared.The results show that the capillaryaction glue welding method can significantly improve the tensile shear performance of aluminum sheet jointscompared to PFSSW and penetration glue welding methods.Methodological support is provided for thejoining process of aluminum sheet metal and other glue welded joints for bodywork.
