摘　　要：针对实际生产中Ｗ６Ｍｏ５Ｃｒ４Ｖ２与４５钢闪光对焊废品率高的问题，通过调整闪光对焊工艺参数，利用拉伸试验、断口分析、金相组织观察，分析了工艺参数对焊接接头性能的影响，并讨论了焊后热处理工艺问题。根据实验结果分析，确定了降低废品率的最佳焊接工艺规范。This paper deals with the high reject rate of flash butt welding for W6Mo5Cr4V2 and 45 steel in practice produce. The effect of technology parameter on welding joint was analyzed by means of tensile test fracture analyzing and microstructure observing. Heat treatment technology was also discussed after welding.According to the experimental results,we abtain the best welding technology parameter for reducing the high reject rate.
