Plasma welding

Plasma welding, developed from the TIG welding process, features high and deep penetration with arc constriction and high energy density. Plasma welding is widely used in automatic installations for the construction of vessels or containers in stainless steel, and in the pipe welding industry for high-quality pressure piping and vessels. Thicknesses of up to 10 mm can be welded in a butt weld configuration with a combined plasma-TIG installation. The process requires two gas flows: a central gas and a shielding gas like ARCAL™.
