Jan 12, 2024 · Gas tungsten arc welding (GTAW), or TIG welding, is an arc welding process that uses a non-consumable tungsten electrode to create an arc and join metal. It requires shielding gas, mostly pure argon or argon mixed with helium.

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.

Oct 11, 2022 · TIG welding can produce clean, precise, aesthetically pleasing welds on a wide range of base materials — making it a good process for critical welds like those found in aerospace, food and beverage equipment fabrication, …

Sep 1, 2021 · How does a TIG welder work? TIG stands for tungsten inert gas and is technically called gas tungsten arc welding (GTAW). The process uses a non-consumable tungsten electrode that delivers the current to the welding arc. An inert gas, typically argon, protects and cools the tungsten and weld puddle.

TIG generates heat via an arc of electricity jumping from a (tungsten metal) electrode to the metal surfaces you intend to weld - usually aluminum or steel. TIG stands for Tungsten Inert Gas, after the tungsten electrode, and the sheath of inert gas (argon or an argon mixture) surrounding it.

Jul 13, 2023 · TIG (tungsten inert gas) welding is a common method used in manufacturing to join pieces of metal together. It’s a form of GTAW (gas tungsten arc welding) and is used for many things, including assembling exhausts, fuel lines, tanks, and structural and engine parts in aerospace and car manufacturing.

Selecting the Right TIG Torch. Consider Amperage Needs: If you consistently weld over 200 amps, a water-cooled torch is ideal. Portability vs. Stationary Use: Air-cooled torches are better for fieldwork, while water-cooled torches excel in shop settings. Ergonomics: A comfortable grip and lightweight design reduce hand fatigue during long welding sessions.

Nov 22, 2024 · In this guide on how to tig weld, I’ll cover the types of TIG and their applications, prerequisites to keep in mind, steps for TIG welding, safety tips, different TIG welding techniques, factors influencing TIG quality, common issues to watch for, aftercare and inspection methods, advantages of TIG welding, its industry uses, and alternatives ...

Mar 5, 2025 · TIG welding (Tungsten Inert Gas welding), is a welding method that uses a non-consumable tungsten electrode to create the weld. The process involves generating an arc between the tungsten electrode and the workpiece, which is shielded by an inert gas, typically argon or helium.

In this guide, we’ll cover the basics of TIG welding, how the process works, and essential tips to help you improve your welding skills and make informed decisions when selecting the right equipment.
