Using heat of high temperature plasma arc to melte the metal portion of the workpiece incision, and used with high-speed plasma momentum to exclude the molten metal to form a processing method incision.
Plasma process equipment work like this: gun nozzle (anode) and the electrode (cathode) generated arc, ionized moisture, so as to achieve the state of plasma. At this time, the internal pressure generated by the ionized vapor is discharged nozzle in the form of a plasma beam, temperature is about 8 000 °С. Use this to carry out noncombustible material cutting, welding, welding and other forms of heat treatment process.
Plasma cutting machines with different working gas can cut a variety of metal, its main advantage is that when cutting thin metal, plasma cutting speed is fast. Plasma cutting machine development to the present, the working gas have a significant affect on cutting characteristics, cutting quality and speed.
