摘　　要：通过试验,比较了在相同焊接规范下镀锌钢板单脉冲和双脉冲点焊工艺性能的差异。试验结果表明,双脉冲焊接参数对镀锌钢板镀锌层有良好的挤出效果;采用双脉冲参数进行焊接时,焊点接头熔核直径更大,焊点接头抗拉剪载荷也更大。Under the same parameters, the differences of spot welding process performance of galvanized steel sheets between single pulse and dual pulse were analyzed. The experiments show that not only zinc coating of galvanized steel sheets can be squeezed, but also the average intensity and nugget diameter are increased by using dual pulse parameters.
