中文摘要：本文针对目前胶焊技术研究的不足，对Q235薄钢板胶焊工艺进行了研究。通过加入铝粉来解决胶粘剂导电性的问题，设计正交试验，研究胶粘剂中铝粉加入量及焊接电流、焊接时间对接头抗拉强度和熔核尺寸的影响。结果表明：焊接电流对胶焊接头性能影响最大；随着胶粘剂中铝粉含量及焊接电流、焊接时间的增加，胶焊接头抗拉强度及熔核尺寸均呈现先增大后减小的趋势。当胶粘剂中铝粉含量为1.2g，焊接电流为5kA，焊接时间为2周波时，Q235薄钢板胶焊接头性能最好。
英文摘要：In this paper, technology of spot weld bonding on Q235 steel sheet has been studied for the current lack of research. Conduction of electricity has been solved by adding aluminum powder to adhesive. The orthogonal experiment was designed by changing the content of aluminum powder, welding current and welding time to find the optimum proportion and the tensile strength and nugget size of the joint were studied. The results show that, the influence of welding current on tensile strength and nugget size of the joint was the largest. With the content of aluminum powder, welding current and welding time increasing, tensile strength and nugget size increase at first and then decrease. When the content of aluminum powder is 1.2 g, welding current is 5 kA, welding time is 2 cycle, the properties of the joint are the best.
