What kind of welder do you use to weld aluminum?

One of the most popular welding processes for aluminum is gas tungsten arc welding (GTAW), otherwise known as tungsten inert gas (TIG) welding. GTAW is a great process for aluminum because it does not require mechanical wire feeding, which can create feedability issues.

Can MIG welders weld aluminum?

To MIG weld aluminum thinner than 14 gauge (. 074 inch), it may be necessary to use specialized pulsed MIG or AC TIG welding equipment. Choose the right gas: Because aluminum is a non-ferrous metal, it requires a 100 percent argon shielding gas. Flow rates of 20 to 30 cubic feet per hour are recommended.

Is welding aluminum difficult?

Aluminum doesn’t act the way other metals do during welding, so it can be difficult to determine weld progress and quality. Simply put, aluminum is difficult to weld because it is a soft, highly sensitive metal insulated by a tougher oxidized layer.
