Micro Plasma Welding

Micro Plasma Welding

  • High energy concentration
  • Higher penetration
  • Low distortion and less tensions
  • Metal sheets weldable with thickness 0.5 mm
  • Used for welding SUB D feedthroughs

Micro Plasma WeldingPlasma welding is similar to TIG welding (gas tungsten arc welding). A second noozle is used in addition to the shielding gas nozzle. Through this second noozle flows plasma gas, surrounding and constricting the arc, which leads to a higher power density and stability compared to TIG welding. The surrounding process gas protects the melt bath of oxidation. The advantages of plasma arc welding are higher welding speed and less distortion as well as a higher insensitivity regarding changes in distance. Due to the stabilizing effect of the plasma it is possible to work even with low currents. This makes plasma welding suitable for joining very thin metal sheets with a thickness from 0.5 mm.
