由于对高焊接速度工艺的需求，必须研究和改进此类技术的稳定性和机理。特别是通过结合激光和电弧工艺，利用相互作用来提高工艺稳定性和焊接速度。为此，开发了一种用于铝无焊剂连接的同轴激光等离子混合焊接工艺。在本文中，报告了该过程中激光和等离子弧之间的相互作用。激光和等离子弧之间相互作用的主要机制是通过改变激光功率、等离子电流和等离子极性等主要参数来确定的。需要这些知识来理解该过程并保证稳定和安全的加入。
Due to the demand for high welding speed processes, the stability and mechanisms of such techniques have to be investigated and improved. Especially by combining laser and arc processes, interactions are used to increase process stability as well as welding speed. For this, a coaxial laser-plasma hybrid welding process for flux less joining of aluminum was developed. In this paper, the interactions between the laser and the plasma arc within this process are reported. The dominant mechanisms of interaction between laser and plasma arc are identified by varying main parameters like laser power, plasma current, and plasma polarity. This knowledge is needed to understand the process and to guarantee a stable and safe joining.
