Welding Magnesium is not something many welders I know are willing to attempt, even though it is possible. Magnesium tends to catch fire if heated too much and god help you put out a magnesium fire once it gets started. Magnesium has a flash point of 883 ˚F and burns at a temperature of 4,000 … Continue Reading
A TIG welder is one of the most precise welding tools you can use for the job and is also capable of good brazing. A TIG welder can be used for both welding and brazing metalworking activities, provided the operator knows how to use it properly. So how do you use a TIG welder to … Continue Reading
TIG welding is perhaps best known for its industrial applications in fields like aerospace and aviation. Because of the precision and intricacy of the welds, it can produce in the hands of a skilled welder, and TIG welding also has a strong association with artistry and craftsmanship. That is why TIG welding is the method … Continue Reading
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 … Continue Reading
When TIG welding aluminum, alternating current (or “AC”) 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 … Continue Reading
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 … Continue Reading
