WELDING | TIG [GTAW] WELDING

TIG (Tungsten Inert Gas) or GTAW (Gas Tungsten Arc Welding), AWS's terminology, is a welding process to AECO infusible electrode (tungsten), under inert gas protection, which can be run with or without filler metal. The welding is performed resulting in melting the edges of the workpiece, possibly making the joint filler material. The electrode, swimming, archery, the filler piece and the adjacent areas are protected from atmospheric contamination by a flow of gas (or mixture) inert effluent from the torch. Considering the particular arc stability, the small size of the heat source and the possibility of using no deposit of filler metal, TIG process is widely used in the production of high quality joints on heat sensitive materials imposed by the welding (Cr-Mo commitment to high temperature, stainless steel, non-ferrous alloys), especially for the realization of the first pass.

Advantages of TIG [GTAW]
Very easy to control the arc, resulting in a remarkable regularity of the deposit;

Possibility of transferring the filler metal in the bathroom without major losses of the elements that constitute it;

Voltage and current adjustable within wide limits, in particular, the minimum can be very small;

Powerful, concentrated heat source;

Ultimately, this procedure is ideal for toddlers and aesthetic weld on carbon steel, low alloy, alloy steel, nickel alloys, aluminum, copper, titanium, magnesium and other non-ferrous alloys.
