What Type Of Shielding Gas For Aluminum Welding. The most popular type of shielding gas in TIG welding is 100 pure argon. In some cases there is tri-mix shielding gas containing 90 Helium 75 Argon and 25Carbon dioxide.

These gases are used as pure argon pure helium and various mixtures of both argon and helium. This type of welding typically has faster travel speeds and higher deposition rates than TIG welding affecting the weld quality. Such gas is a viable choice for steel but aluminum cannot handle the reactive C02 gas.
Stainless Steel MIG weld done with C2 gas.
Some gases are better suited than others for the most commonly used base materials whether its aluminum mild steel carbon steel low-alloy steel or stainless steel. Its used in both the primary welding stage and to purge the backside of the joint. A - There are two shielding gases commonly used for arc welding aluminum and these are argon and helium. Such gas is a viable choice for steel but aluminum cannot handle the reactive C02 gas.
