摘要
采用电阻点焊、胶接点焊和塞焊三种焊接方法,对3mm+3mm 09CuPCrNi钢搭接接头的组织和力学性能进行对比研究。结果表明:三种焊接方法下焊接接头的剪切拉伸性能均满足标准,其中塞焊时接头剪切拉伸性能较好;电阻点焊和胶接点焊接头各区域硬度相近且高于塞焊下接头各区域硬度;塞焊接头的组织与电阻点焊和胶接点焊接头组织有所不同;点焊及胶接点焊焊接接头的熔透率均满足相关标准。
In this paper,mechanical properties of the thickness of 3 mm＋3 mm 09CuPCrNi lap joints are compared by resistance spot welding,spot weld-bonding and plug welding. The results show that：the tensile shear properties of welded joints under three welding methods to meet the standards,and plug weld joint tensile shear property is better;the hardness of joints regions by resistance spot welding and spot weld-bonding is similar and higher than the plug welding joint;the organization of plug welding joint is different from the organization of resistance spot welding joint and resistance spot welding joint; penetration rate of spot welding and spot weld- bonding joints could meet the relevant standards.
