Plasma Arc welding

The plasma arc welding process uses a water-cooled nozzle to constrict the arc and thus to increase the power density. An additional shielding gas envelope surrounds the plasma arc and protects the melt pool from atmosphere influences. So the molten workpiece edges flow into each other and solidify to form the weld seam.
The plasma arc welding process offers many advantages: high productivity through high welding speeds, high quality of the weld achievable,high process safety and high automation grade.
