# WHAT TYPE OF SHIELDING GASES TO USE FOR THE GTAW OR TIG PROCESS? The shielding gases used in the GTAW (Gas Tungsten Arc Welding) or TIG (Tungsten Inert Gas) process must be **inert**, meaning they do not react chemically with the weld pool, the base metal, or the tungsten electrode. The most commonly used gases are: — ## **1. Argon (Ar)** – Most widely used shielding gas for TIG welding. – Provides excellent arc stability. – Offers good cleaning action on aluminum and magnesium (when using AC current). – Suitable for welding most metals: carbon steel, stainless steel, aluminum, copper, titanium, and nickel alloys. – Lower ionization potential allows easier arc starting. — ## **2. Helium (He)** – Produces a hotter arc than argon, allowing deeper penetration and faster travel speeds. – Used for welding thicker sections and highly heat-conductive metals such as copper and aluminum. – Requires higher flow rates

One of the main functions of these types of gases is to eliminate Hydrogen, Nitrogen, and Oxygen from…
