The TIG (Tungsten inert gas) welding by Fronius is a gas shielded welding, part of the fusion welding processes. It is used especially where optimum quality, spatter and free seams are required. TIG welding is suitable for stainless steels, aluminum, nickel allow, and thin sheet metal made of aluminum. It is mostly used in pipeline, container construction, portal construction and aerospace applications, with a required current supplied via tungsten electrode. These electrodes are temperature-resistant and non-melting, emitting an arc, heating up and liquefying the material. A nozzle around the shielding gas protects the heated material from chemical reaction with the ambient air. 

Uses electrodes that go up to 3380°C

Furthermore, the electrodes use a sintering process and can be alloyed with oxide additives. They have also adopted a color-code according to the different alloy. The different alloy can be for example, pure tungsten (W) or rare earth oxide (WS2). Indeed, with the TIG Welding there is no formation of welding spatter, a high optical quality of weld seems, possibility of all welding positions and a very high weld seam quality. Finally, a range of variant are included in the process such as cold wire TIG welding, hot-wire TIG welding, Arctig, Cladding and an Orbital welding. With a mechanized wirefeeder, the cost-effective welding can be achieved for sheet thicknesses of less than 4 mm.
