激光-弧焊复合焊接的效益与适当的参数设置密切相关。因此，基本的优化需要深刻理解所涉及的相互作用机制的相关性。然而，在文献中对这些问题进行了不同的评价和讨论。本文对激光-电弧加工领域中最流行的假设进行了综述。通过自己的实验和数值研究，特别考虑了激光辐射与弧光等离子体直接相互作用的重要性以及金属蒸发的作用。这一分析结果表明，从工艺稳定性和性能方面来看，这些现象不能作为激光-电弧复合焊接协同成果的主要驱动机制。激光-电弧复合焊接取得的效益与适当的参数设置密切相关。因此，基本的优化需要深刻理解所涉及的相互作用机制的相关性。然而，在文献中对这些问题进行了不同的评价和讨论。本文对激光-电弧加工领域中最流行的假设进行了综述。通过自己的实验和数值研究，特别考虑了激光辐射与弧光等离子体直接相互作用的重要性以及金属蒸发的作用。分析结果表明，这些现象不能作为激光-弧焊在工艺稳定性和性能方面取得协同成就的主要驱动机制。
Achievable benefits in hybrid laser-arc welding are closely related to suitable parameter settings. Basic optimizations consequently need a profound understanding of the relevance of involved interaction mechanisms. These are however differently evaluated and discussed in literature. This paper gives an over-view on the most popular hypotheses in the field of laser-arc processing. The importance of direct interactions between laser radiation and arc plasma as well as the role of metal evaporation are particularly considered by own experimental and numerical investigations. The results of this analysis suggest that these phenomena cannot be regarded as main driving mechanisms for synergistic achievements in hybrid laser-arc welding with respect to process stability and performance.Achievable benefits in hybrid laser-arc welding are closely related to suitable parameter settings.
