摘　　要：激光-电弧复合焊接过程中,由于引弧产生的高频干扰了激光器的控制系统,造成了激光和电弧不能实现复合焊接。通过分析研究高频引弧对焊接电源和激光器的干扰途径,采取相应的措施,有效地消除了高频干扰问题,成功实现了激光和电弧之间的复合焊接。In the course of laser-arc hybrid welding,the high frequency caused by drawing arc interfered the control system which make the laser and electric arc not able to realize the hybrid welding.In this paper,the interference way to the welding power and laser of high frequence was studied,and the interference problem was elimined by adopting the corresponding measure,and the hybrid welding between laser and electic arc was successfully realized.
