| 摘 要： | 采用电阻铆焊方法对铝合金A6061与低碳钢Q235进行了焊接. 通过扫描电子显微镜对接头微观组织进行了观察，分析了接头界面区组织，研究了焊接电流对接头抗剪载荷的影响. 在铝/铆钉、铝/钢接合界面均观察到了反应层的形成，通过成分分析得知生成两界面的反应物分别是FeAl与FeAl3；而钢板/铆钉界面接合较好. 焊接电流为21 kA时所得接头的抗剪载荷最大为3.85 kN. 结果表明，采用电阻铆焊方法焊接铝合金与钢是比较有效的.

| Abstract: | A new joining method termed resistance rivet-welding was tried to weld steel/aluminum alloy. The interfacial microstructure was observed by using scaning electron microscopy. A reaction layer of FeAl was observed at the rivet/aluminum alloy interface, whereas the reaction product of FeAl3 was detected at the interface between steel and aluminum alloy. The joining between steel Q235 and rivet was sound. The maximum tensile shear load of 3.85 kN was obtained at welding current of 21 kA. The results reveal that resistance rivet-welding is a relatively effective method for joining steel and aluminum alloy. |
