1) Basic principles

Plasma arc processing is a special processing method that uses the thermal energy of plasma arc to cut, weld and spray metal or non-metal.

(2) Main features

1) Micro-beam plasma arc welding can weld foils and thin plates;

2) It has a small hole effect and can better achieve single-sided welding and double-sided free forming;

3) The plasma arc energy density is high, the arc column temperature is high, and the penetration ability is strong. Steel with a thickness of 10-12mm does not need to be grooved, and can be welded on both sides at one time. The welding speed is fast, the productivity is high, and the stress deformation is small;

4) The equipment is relatively complex and consumes large amounts of gas, so it is only suitable for indoor welding.

(3) Область использования

It is widely used in industrial production, especially the welding of copper and copper alloys, titanium and titanium alloys, alloy steel, нержавеющая сталь, molybdenum and other metals used in aerospace and other military and cutting-edge industrial technologies, such as titanium alloy missile casings, aircraft Some thin-walled containers, и т. д..
