| 摘 要： | 采用MULTISPOT MI-100电阻焊机,对车身用6061-T6铝合金薄板实施电阻点焊,研究并得到电阻点焊最佳工艺参数。然后,运用正交试验方案和极差分析方法对电阻焊工艺参数进行试验和进一步优化设计。在对2mm厚度的6061-T6铝合金薄板进行搭接电阻点焊后,分析焊接外观并完成拉伸测试,测试结果表明:当焊接电流60KA、焊接压力0.63MPa、板材厚度2.00mm时,试样所获得的点焊接头无明显缺陷,成型较好,具有良好的焊接质量和外观,其抗拉剪力值最大为5.583KN。

| Abstract: | Resistance spot welding of 6061-T6 aluminum alloy sheet for car body was studied by using MULTISPOT MI-100 resistance welding machine.The purpose is to find out the best process parameters of its resistance spot welding.The orthogonal test scheme and range analysis method were used to test and optimize the process parameters.After performing resistance spot welding of 2 mm thick 6061-T6 aluminum alloy sheet,the weld appearance was analyzed and the tensile test was carried out.The results show that when the welding current is 60KA,the welding pressure being 0.63Mpa,and the plate thickness being 2.00mm,the spot welding joints obtained from this group of samples enjoy good welding quality and appearance,the maximum tensile shear value of which is 5.583 KN. |
