Plasma welding system

Plasma welding

The term plasma characterises a special state of matter. Plasma is a dissociated and an ionised gas, which has the ability to conduct electrical current, but is itself electrically neutral to the outside. The electrical light arc is a suitable source of heat for generating a thermal plasma.

Differences of the plasma technology as compared to the conventional light arc welding methods lie in:

  • high-power density of the plasma arc
  • higher heat effect as compared to a “normal “light arc
  • strong mechanical effect of the plasma arc on the work piece

Plates with a diameter of up to 5000 mm and strength from 3 to 20 mm are welded in our plants with a combined PLASMA-WIG method of the company SAF. This method guarantees economical and high quality welding results.
