Welding Aluminum

Aluminum is a lightweight, soft, low-strength metal that can easily be cast, forged, machined, formed, and welded. Unless alloyed with specific elements, it is suitable only in low-temperature applications. Aluminum is light gray to silver in color, very bright when polished, and dull when oxidized. A fracture in aluminum sections shows a smooth, bright structure. … Read more

MIG Welding Aluminium

MIG Welding Aluminum is a fast, adaptable process that is used with direct current reverse polarity and an inert gas to weld heavier thicknesses of aluminum alloys, in any position, from 1/16 in. (1.6 mm) to several inches thick. Shielding gas for MIG Welding Aluminum. Precautions should be taken to ensure the gas shield is extremely efficient. … Read more

Gas Welding Aluminium

Gas Welding Aluminum. Aluminum is readily joined by welding, brazing, and soldering. In many instances, aluminum is joined with the conventional equipment and techniques used with other metals. However, specialized equipment or techniques may sometimes be required. The alloy, joint configuration, strength required, appearance, and cost are factors dictating the choice of process. Each process has … Read more

Can Your Welding Machine TIG Weld Aluminum?

Arc Welding Aluminum: How to Stick Weld Aluminum

When arc welding aluminum with the shielded metal-arc welding (SMAW) process, a heavy dipped or extruded flux coated electrode is used with DC Reverse Polarity (DCRP). The electrodes are covered similarly to conventional steel electrodes. The flux coating provides a gaseous shield around the arc and molten aluminum puddle, and chemically combines and removes the aluminum oxide, … Read more

Tig Welding Aluminium

The TIG (Tungsten Inert Gas) arc welding process is used for welding the thinner sections of aluminum and aluminum alloys. There are several precautions that should be mentioned with respect to using this process. Alternating current is recommended for general-purpose work since it provides the half-cycle of cleaning action. Table 7-22 provides welding procedure schedules for using … Read more
