Inert Gas For Welding Aluminum. The helium content gases are usually more expensive. The weldability also known as joinability it refers to the joining properties of the material to be welded and also selecting the best suitable welding method to weld that material.
My starter welder is a Hobart Ironman 210 purchased at an auction for 600. TIG Tungsten Inert gas Welding is best suitable to weld aluminum and aluminum alloys. Tungsten Inert Gas welding also known as Gas Tungsten Arc Welding has several advantages over other forms of welding.
Pure argon can be used for both GMAW and GTAW welding and is the most popular of the shielding gases used for aluminum.
One major study on aluminum stiffened plates was conducted by Paik et al. A Practical Guide to TIG GTA Welding 1991. One major study on aluminum stiffened plates was conducted by Paik et al. Then I purchased a 5 foot tall 300 cubic foot gas bottle for the argon gas needed for aluminum welding.
