摘要: 文中采用精密电阻焊进行高速钢M51与高强度弹簧钢B318异种钢材焊接，着重分析了焊接电流对接头特性四个指标(接头剪断力、热影响区大小、挤出熔渣量、有无飞溅情况)的影响. 结果表明，焊接电流与接头剪断力呈抛物线关系，焊接电流自900 A上升到1 300 A时，接头剪断力随之增加并达到峰值，当焊接电流达到1 400 A时，由于焊接能量过大出现熔渣飞溅现象，接头剪断力下降；随着焊接电流增加，热影响区的大小及挤出熔渣量也呈现先增大后减小的趋势. 文中还结合微观组织分析了焊接电流对焊缝质量的影响机理.Abstract: In this study, dissimilar steels of high speed steel M51 and high strength spring steel B318 was welded by the precision resistance welding method. The influence of welding current on four indexes of joint characteristics (shear force, heat influence zone, extrusion slag amount and splash condition) is analyzed emphatically. The results show that the welding current is in parabolic relationship with the shear force of the joint. When the welding current rises from 900 A to 1 300 A, the shear force of the joint increases to a peak value, and when the welding current reaches 1 400 A, the shear force of the joint decreases due to slag spatter result from excessive welding energy. With the increase of welding current. The size of heat affected zone and the amount of molten slag in extrusion increase firsty and then decrease. Finally, the influence of welding current on weld quality is analyzed with microstructure.
