Welding Gas For Aluminum Tig. The paper presents the results of tungsten inert gas TIG welding of aluminium alloy 7075-T6 in the butt joint with single-V edge preparation. Many metalworkers find that aluminum that is to thick to weld with argon even with the amperage cranked all the way up welds just fine with helium.
The inert gas belongs to the working situation and the base metal on which the welding works proceeding Mostly the argon and helium gases are used because as per function and inert gas protects the welding area against the environmental particles. The sample dimensions were 100. Pure Argon is the most commonly used one of the two and is best applied for gas welding aluminum and carbon steel.
Mixtures of argon and helium are probably the next common and pure helium is generally only used for some specialized GTAW applications.
And which gas is mostly compatible with the TIG welding process. A TIG welder basically comes with both AC and DC power options. Since youre going to weld aluminum using TIG welding youll need to choose either the DC positive or DC negative power. Ad Find China Manufacturers Of Aluminum Welding.
