摘要

等离子弧焊是一种高能量密度的电弧焊技术，采用水冷喷嘴压缩电弧形成具有较大冲击力的等离子体，可以不开坡口直接实现单面焊双面成型。采用常规的数理解析法和试验的方法研究电弧和熔池具有局限性，数值模拟的方法更为快速、有效，很大程度上可反映出等离子弧焊接过程中复杂的物理机制，可为实际的等离子弧焊接过程提供理论指导与参考。从等离子弧焊接过程中的电弧、熔池、电弧与熔池的耦合这3个方面阐述等离子弧焊在数值模拟方向所取得的研究进展，并指出未来发展趋势。

Abstract

Plasma arc welding is a high energy density arc welding technology

it adopts water-cooled nozzle to compress arc to form plasma with large impact force

which can directly realize single-side welding and double-side forming without opening groove. The conventional theoretical analysis and experimental methods have limitations in the research of arc and weld pool

the numerical simulation method is more rapid and effective

which can reflect the complex physical mechanism of plasma arc welding to a large extent

it can provide a theoretical guidance and reference for the actual plasma arc welding. The progress of plasma arc welding in the direction of numerical simulation from three aspects: arc

weld pool and the coupling between arc and weld pool is described.
