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
