What welder do I need to weld aluminum?
The right Welder is essential if you’re going to work with aluminum. For aluminum, a TIG – tungsten inert gas – welding machine is a better choice than a MIG machine. While MIG machines can be used, TIG machines are preferred by most professionals taking on complex aluminum welding tasks. Welding torch.
Do you weld aluminum hot or cold?
Soft metals, like aluminum or copper, are the best choices for cold welding. In a Butt joint, removing the barrier layer of the metal is not often required as the plastic deformation that happens during the joining process breaks up the barrier automatically.
Is MIG or TIG better for welding aluminum?
Generally, two processes are used for aluminum welding: GTAW (TIG) and GMAW (MIG). Most welders in the business will say TIG is the better option for welding aluminum because it allows for better results on lighter gauge materials. When done correctly, TIG welding aluminum can produce quality welds.
How do you weld aluminum without cracking it?
To counteract cracking problems, use reputable filler alloys that have grain refiners added, such as titanium or zirconium. Use the highest welding speed possible. The faster the weld is conducted, the faster the cooling rate and the less time the weld is in the hot cracking temperature range.

Do you have to use argon to weld aluminum?
Welding aluminum without gas is possible, but not for typical applications. The most common types of welders rely upon inert gases like argon in order to ensure a proper seal. Without a gas like argon present, atmospheric gases will lead to degradation of the aluminum before it can set.
How do I stop my aluminum weld from cracking?
To prevent cold cracking you can try pre-heating the base material in order to reduce the speed of cooling. You can also use welding consumables that are low in hydrogen to minimize the hydrogen that is diffused into the weld.
