摘　　要：激光深熔焊接过程中,光致等离子体对激光能量有显著的屏蔽作用,严重影响了焊接质量,因此,对等离子体的控制技术成为研究的热点。本文在简要介绍等离子体形成、分类的基础上,系统归纳了国内外几种控制等离子体的方法,并对这几种方法进行了比较。其中,详细介绍了真空焊接法。During laser penetration welding, laser induced plasma has obvious shielding effect on laser energy and affects welding quality significantly. Therefore, the control technology of plasma becomes a key of laser penetration welding. The methods to control the plasma are summarized and compared. The vacuum laser welding is introduced in details.
