摘　　要：提出了一种TIG+MIG交替双弧复合焊接工艺方法,其MIG主电弧存在于焊丝和母材之间,TIG辅助电弧一端在钨极上,另一端在焊丝和母材之间切换,适当调节辅助电弧两个状态的时间比率和强度,可以实现熔敷金属量和热输入量的相对独立控制。设计交替双弧复合电源并进行工艺试验,结果表明,TIG+MIG交替双弧复合焊改变了电弧能量的分布,同时在保证母材热输入不变的情况下,能够增大流经焊丝的电流。An alternating TIG＋MIG double arc hybrid welding process is presented whose main arc exists between the welding wire and the base material, one end of auxiliary arc exists in the tungsten electrode and the other end switches between the welding wire and the base material. The relatively independent control of the amount of deposited metal and heat input can be achieved by adjusting the time ratio and strength of the two states in the auxiliary arc appropriately. Design an alternating TIG＋MIG double arc hybrid welding equipment and welding experiments ,the results show that TIG＋MIG alternating double arc hybrid welding has changed the distribution of arc energy, and increased the current flows through wire while ensuring the unchangeable heat input.
