Process Plasma welding
Plasma welding is used where deep narrow welds are needed and where attention is focused on thermal distorsion and welding speed. Because of the very focused heat source a combination of thin and thick plates can be welded.

Plasma is ionized gas at very high temperatures (30.000 C). The plasma is generated by sending a jet of gas through an electric arc. Plasma welding is only done on automatic machines.

Very suitable method for non-continuous welding with many starts and stops, thanks to a pilot arc.
