Cleaning aluminum before welding is a vital step in preparing the metal to prevent corrosion and other problems. So how do you clean aluminum before welding? This preparation step contains two major steps: Degrease the aluminum so that no residual contaminants or moisture remains. This process removes substances from the surface of the aluminum that … Read more
When TIG welding aluminum, alternating current (or “ACâ€) is almost always used. Alternating current has a scrubbing effect on the surface, breaking up oxides that limit weld quality. However, it is possible to TIG weld aluminum with direct current (also called “DC”). Sometimes, DC is a better choice to TIG weld aluminum. How and when … Read more
This process is also known as fusion welding or autogenous welding. With any technology as versatile as TIG welding—“there’s a time and a place for everything” is a pretty safe rule of thumb. However, most TIG pros agree that when it comes to skipping filler rod, it’s more important to know when you can and … Read more
