How Do You Weld Aluminum With A Tig?
TIG (Tungsten Inert Gas) welding machines—also called GTAW welders, or Gas Tungsten Arc Welders—use pure tungsten melted by a gas such as argon to create welds. This type of machine is something that even the above-average handyman does not usually own, due mainly to the cost. (Low-end TIG welding machines can go for as much as $2,500, and the better machines can cost upwards of $6,000.) When welding aluminum in a non-commercial environment, extra care should be taken to remove flammables such as saw dust or gasoline from the welding area. Step 1 Clean the aluminum to be welded. This is especially true for aluminum that looks new. Spray the aluminum to be welded with brake cleaner and rinse it off with the spray bottle of distilled water. Use the stainless-steel brush to bring the aluminum to a shine where it will be welded. Step 2 Use the clamps or vice grips to hold the copper heat sink bar to the metal. Step 3 Preheat the aluminum to at least 275 degrees Fahrenheit with the blow
