Orbital welding has almost always exclusively been carried out by the Tungsten Inert Gas (TIG / GTAW) technique using non-consumable electrodes, with additional cold-wire feed where necessary. The easy control of heat input makes TIG-welding the ideal welding method for fully orbital welding of tubes with specialist orbital welding heads, that incorporate a clamping device, a TIG electrode on an orbital travel device and a shielding gas chamber. Many different types of metal can be welded; high-strength, high-temperature and corrosion-resistant steels, unalloyed and low-alloyed carbon steels, nickel alloys, titanium, copper, aluminum and associated alloys. Carried out in an inert atmosphere, this controlled technique produces results that are extremely clean, have low particle counts and are free from unwanted spatter. This enables the highest demands to be met regarding the mechanical and optical properties of a weld seam.
