Ive seen many aluminium wheels that were MIG Metal Inert Gas welded and its a disaster. If possible preheat the aluminum up to 300 degrees Fahrenheit that will help you easily weld this tricky metal. It does not have to be a big thick piece of copper either.

For welds needing deeper. Aluminum alloy must be welded with a process called TIG tungsten inert gas welding. A clean ss wire brush a piece of copper for backing tig gloves a tig finger and a clamp to hold the copper backing in place.

Watch hand and torch placement. Not my favorite thing but Im going to try a little quarter inch lap joint and well do a cut and etch test on it compare results from stick welding cold with no pre-heat to weld it while its hot from. The other hand is reserved for the metal filler rod.

We cover basics for beginners who want to TIG wel. Use an AC polarity Aluminum easily forms an oxide layer that is not easily visible to the naked eye. You can use MIG wire as a filler and then start at 20 amps.

The oxide layer can be cleaned using a carbide cutter but there are high chances that it will develop back once welding begins. The copper backing is key. When you get a puddle formed bump your amps to 25 and begin running beads around switching the can between welds.

Since youre going to weld aluminum using TIG welding youll need to choose either the DC positive or DC negative power. After that start to weld the front side while some heat is still available on the wheel. TIG welders should be aware of this factor when welding aluminum.

A TIG welder basically comes with both AC and DC power options. Aluminum oxide forms on the surface of all aluminum alloys. Hold the torch at 10-degree angle and the filler at 90-degree angle to work effectively with the aluminum.

The bead is much thinner and weaker and the process burns the heck out the surrounding alloy weakening the entire area around the weld.

Learn how to TIG Weld. Aluminum wheels that are MIG metal inert gas welded are a disaster. Learning to TIG aluminum.

TIG welding aluminum doesnt need to be intimidating. This includes argon and a slight composition of helium gas. Ensure there are no pores in the welding.
