TIG stands for tungsten inert gas welding or sometimes this welding is known as gas tungsten arc welding. In this welding process, the heat required to form weld is provided by a very intense electric arc which is form between tungsten electrode and work piece. TIG welding (Tungsten Inert Gas welding) is one of the most versatile and reliable welding methods in modern manufacturing. It’s known for producing clean, strong, and visually appealing welds across a wide range of metals. This guide explains how TIG welding works, its advantages, and where it’s used across industries. What Is TIG Welding? TIG welding uses a non-consumable tungsten electrode to join metals. The process relies on an inert shielding gas, usually argon, to protect the weld ... Tungsten arc welding Gas tungsten arc welding (GTAW, also known as tungsten inert gas welding or TIG, tungsten argon gas welding or TAG, [citation needed] and heliarc welding when helium is used) is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium). A filler metal is normally used, though some welds, known as ... 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 ...
