Aluminum is a light, soft, silvery-gray metal used in a wide variety of products such as foil paper, soda cans, window frames and even airplane parts. Because of its light weight and high strength, it is the second most popular welded metal. Aluminum welding is the process of joining two aluminum metal components by melting them. Brady's Welding Specialties, an expert contractor in Tacoma, WA, gives us a quick guide to the process of aluminum welding.

Preparation

To weld aluminum, several tools must be prepared beforehand. A tungsten inert gas (TIG) welder is generally the preferred welding tool, as its tungsten electrode assures the highest precision. An aluminum filler rod bonds the two pieces together, while argon gas is used for shielding. Proper protective garments are important as well, as welding can be a hazardous task. Wear a thick cotton shirt, insulated and fire-resistant gloves, and a helmet with a lens that darkens during welding. Keep a fire extinguisher handy as well, just to be safe.

Aluminum Welding

First, the aluminum pieces must be preheated to about 350 degrees Fahrenheit, either in an oven or by using a gas torch. The pieces are then fit together as tightly as possible and clamped in place, where they are welded together. It’s always best to leave this specialized work to the professionals.
