features of plasma welding:
1) High arc energy and strong penetration
2) The arc column is slender, and the thin workpiece does not need beveling, which shortens the preparation time<
3) The quality of weld is not sensitive to the change of arc length, because the shape of plasma arc is close to cylindrical. The divergence angle is very small (about 5 degrees) and has good straightness. When the radian changes, the area of heating spots has little effect, so it is easy to obtain a uniform weld state
4) Fast speed, 3-5 times that of ordinary argon welding
5) High energy density and strong arc directivity can produce stable keyhole effect. Good single-sided welding and double-sided forming can be obtained through the keyhole effect
6) The arc column has good controllability and adjustability
7) Excellent repeatability, electrode retracted in nozzle, not easy to pollute and burn, long service life
8) The tungsten electrode shrinks inside the water-cooled nozzle and does not contact the workpiece, so it can effectively avoid tungsten inclusion in the weld metal. In addition, the arc has good agitation and high bath temperature, which is conducive to the release of gas in the bath
Product Application It is applicable to the welding of low carbon steel, high and low alloy steel, stainless steel, titanium alloy, copper, nickel and their alloys, and can meet the needs of precision welding and high-quality and efficient welding in chemical industry, pressure vessel industry, aerospace and weapon industry
