Plasma welding is between the electrode and the workpiece, through the special compression mechanism of the welding torch, the formation of a stable plasma compression arc as a heat source, the resulting high temperature alloy powder and the surface of the substrate quickly heated and melted, mixed, diffusion, solidification, forming a layer of high-performance alloy layer, so that the surface of the parts with better high temperature resistance, corrosion resistance and wear resistance of the welding process, it is a new surface cladding modification technology with high quality, high efficiency and low cost.

Plasma gas is generally 99.99% of high-purity argon, with good ionization capacity and arc stabilization effect, the protective gas is generally high-purity argon, but also according to the different materials of argon, hydrogen and helium and other different ratios.
