| 目的 介绍一种称为Tri-Arc的新型双丝电弧焊接方法。方法 将Tri-Arc双丝电弧焊与应用较广的Tandem双丝电弧焊的系统构成和焊接电流波形进行对比分析。结果 Tri-Arc和Tandem两种双丝电弧焊接方法所使用的双丝焊枪相近，双电源相位同步控制和U/I脉冲控制方式类似。Tri-Arc和Tandem两种双丝电弧焊接方法的差异在于：Tandem双丝电弧焊的2个电弧是相对独立的，而Tri-Arc双丝电弧焊的2个电弧是相互耦合的，因此Tri-Arc双丝电弧焊又具有旁路耦合电弧的某些特点。结论 这种新型的Tri-Arc双丝电弧焊不仅具有与Tandem双丝电弧焊一样的高焊丝熔敷率，而且具有比Tandem双丝电弧焊更低的焊接热输入。 |

| The paper aims to introduce a novel dual wire arc welding method called Tri-Arc. By comparison and analysis of the system composition and welding current waveform between the Tri-Arc dual wire arc welding and the widely used Tandem dual wire arc welding, it was found that the commonness of the two double wire welding methods was using similar dual wire welding torch, similar double power phase synchronous control and U/I pulse control mode, etc. The difference between the two dual wire arc welding methods was that the two arcs of the Tandem dual wire arc welding were relatively independent, while the two arcs of the Tri-Arc dual wire arc welding were coupled with each other. As a result Tri-Arc dual-wire arc welding had some characteristics of bypass coupling arc. The results show that this new Tri-Arc dual wire arc welding not only has the same high wire deposition rate as Tandem dual wire arc welding, but also has lower welding heat input than Tandem dual wire arc welding. |
