摘要:

在建立和研究空心钨极电弧的基础上,对激光一同轴电弧复合焊接热源焊接特性进行了深入研究。试验结果表明,激光与电弧相互作用增强的效果十分显著,采用同轴电弧作为辅助热源增大焊接熔深的效力优于激光一旁轴电弧复合焊接热源焊接效果。在试验的基础上,得到了激光一同轴电弧复合焊接热源焊接熔深的变化规律。

Abstract:

In this artide, the character of combined laser-coaxlsal arc heat source is deeply studled on the basis of understanding hollow tungsten electrode arc. The result states that the combined heat source has a remarkable effect on the enhancement of Welding penetration due to their action each other.As auxilary heat source, the coaxisal arc has more irfluence on augmenting penetnltion depth than the non-coaxisal arc. The variation rule of the welding penetration depth with the combined laser-coaxisal arc is given based on the experiments.
