Effects of Metal Vapor on Thermodynamic State in Helium GTA(Physics, Processes, Instruments & Measurements)
Search this Article
In order to investigate effects of metal vapor on the thermodynamic state of arc plasma in the welding process, electron temperatures in the pure helium plasma and helium plasma during welding in Gas Tungsten Arcs (GTA) were measured by using the laser scattering method. The experimental results showed that metal vapor led to a significant decrease in the electron temperature compared with that of pure helium GTA plasma.
