为了研究焊接过程中金属蒸气对等离子体状态的影响，采用激光散射法测量了焊接过程中氦钨极电弧（GTA）等离子体中的电子温度。此外，还通过使用光谱分析测量了金属离子的密度分布。结果表明，焊接过程中的等离子体由纯氦等离子体区和准金属等离子体区组成。
In order to investigate effects of metal vapor on the plasma state in welding process, electron temperature in helium Gas Tungsten Arc(GTA) plasma during welding was measured by using the laser scattering method. Furthermore, density distributions of metal ions were also measured by using the spectroscopic analysis. Our results showed that plasma during welding consisted of two plasma regions, namely, pure helium plasma region and quasi-metal plasma region.
