Plasma arc welding is a common metal and non-metallic materials cutting process. Which heats and melts the material with high-speed, high-temperature and high-energy plasma gas flow, and discharges the molten material by means of internal or external high-speed air or water until the plasma gas stream penetrates the back surface.
According to the different ways of power connection, plasma arc is divided into non-transfer type, transfer type and joint type. Widely used in industrial production, especially aerospace and other military and cutting-edge industrial technology.
