研究了激光-气体保护钨极电弧焊（LT）和激光-气体保护金属极电弧焊（LM）中激光与电弧等离子体相互作用的差异。研究了低温热源和激光热源的等离子体行为、热穿透能力和光谱信息等特性。基于等离子体放电理论，对等离子体放电过程中的相互作用进行了建模和分析。结果表明，在激光焊接和激光焊接过程中，小孔等离子体与电弧发生耦合放电，对电弧有强烈的强化作用。但是，当调整焊接参数时，LT焊的强化效果比LM焊的要敏感得多。
This paper describes an investigation on differences in interactions between laser and arc plasma during laser-gas tungsten arc (LT) welding and laser-gas metal arc (LM) welding. The characteristics of LT heat source and LM heat source, such as plasma behavior, heat penetration ability and spectral information were comparably studied. Based on the plasma discharge theory, the interactions during plasma discharge were modeled and analyzed. Results show that in both LT and LM welding, coupling discharge between the laser keyhole plasma and arc happens, which strongly enhance the arc. But, the enhancing effect in LT welding is much more sensitive than that in LM welding when parameters are adjusted.
