| 摘 要： | 从接头的拉剪力、熔核的微观组织、动态电阻曲线和焊接性范围4个方面.对比分析双相钢透胶胶焊和电阻点焊的接头性能.结果表明,胶焊熔核开始形成时间提前于点焊,使得在小电流情况下胶焊的焊点拉剪力要普遍高于点焊;胶焊在中等电流情况下便会产生严重飞溅,使得在大电流情况下点焊焊点拉剪力要更高些.因此,在制定胶焊的焊接工艺参数时应选择比电阻点焊偏低的焊接电流,而适度增加焊接过程的电极力有利于抑制飞溅产生.

| Abstract: | The joint performances between weld-bonding and resistance spot welding(RSW) are compared by tensile-shear force of nuggets, microstructure of nuggets, dynamic resistance curves and weld lobes.Experimental results show that the tensile-shear force of weld-bonded nuggets is much higher than that of spot-welded nuggets when lower welding current is used;oppositely tensile-shear force of spot-welded nuggets is a little higher than that of weld-bonded nuggets when higher welding current is used, but severe spatter will occur.Therefore, lower welding current in weld-bonding of steel comparing with that of RSW and larger electrode force during welding will inhibit spatter. |
