Tig welding: GTAW welding is based on the

GTAW welding is based on the principle of creating an electric arc between a non-consumable tungsten electrode and the workpiece. Tungsten inert gas welding (TIG welding) is a gas shielded welding process and is one of the fusion welding processes. It is used wherever optimum quality and spatter-free weld seams are required. TIG welding is suitable, among other things, for stainless steels, aluminum and nickel alloys as well for thin sheet metal made of aluminum and stainless steel. It is used in pipeline and container construction, in portal construction and in aerospace applications. TIG means Tungsten Inert Gas welding—I break down how it works, why I use it for stainless and aluminum, and how to control heat for clean joints. What is TIG welding and how does it work? Tungsten inert gas (TIG) is a welding process that uses electricity to melt and join pieces of metal. This blog explains how it works, and when you should use it for your sheet metal fabrication projects. TIG welding was invented in the 1940s to meet the challenge of welding light metals such as magnesium and aluminium in the Californian aerospace industry. (Both metals heat up very fast, melt easily and have oxidation issues.) Since then, the ...
