Gas Welding Aluminum Sheet. Metal inert gas is normally used for welding aluminum. The gas welding processes most commonly used on aluminum and aluminum alloys are oxyacetylene and oxyhydrogen.
Gas welding of aluminum or other alloys is a snap with the HTS-2000 brazing rod. High weld speed and low distortion properties on steel sheet have ensured its home in these shops when used properly. Aluminum welding is usually performed with alternating current and some type of remote control that allows the welder to adjust current while welding sometimes well below 10 amps for some material.
This type of welding typically has faster travel speeds and higher deposition rates than TIG welding affecting the weld quality.
Well be showing you the process on some thin body aluminum. Because aluminum is a non-ferrous metal it requires a 100 percent argon shielding gas. Metal inert gas is normally used for welding aluminum. To weld sheet metal with solid wires use electrode positive EP or reverse polarity.
