Increase the compression degree can make arcof high temperature plasma jet extended, form more uniform high temperature area, and increase the speed of the jet, can reduce the width of the poor.
During the laser-TIG hybrid process, the arc keeps stable when the welding speed increases because of the inducting and compressionof laser on the TIG arc.
激光与电弧的复合热源在焊接过程中，由于激光的压缩与引导作用，可以在焊接速度增加时，电弧仍然较稳定。

The illinium electrode produces a slim arc when used in welding. With a high level ofcompression, it has a bigger melting depth in medium and high currents.
