Welding Aluminum Smaw. When arc welding aluminum with the SMAW process a heavy extruded or dipped flux coated electrode is used with DC Reverse Polarity. Some of the advantages of using shielded metal arc welding include.
Although it is possible to weld aluminum with stick welding it. Stick electrode welding This is a nonstandard term for Shielded Metal Arc Welding SMAW Prior to the development of the inert gas welding process GTAW GMAW the arc welding of aluminum was mainly restricted to the Shielded Metal Arc Process SMAW sometimes referred to as the Manual Metal Arc Process MMA. 2 Following are a few considerations for each of the most popular aluminum welding processes.
When arc welding aluminum with the SMAW process a heavy extruded or dipped flux coated electrode is used with DC Reverse Polarity.
To weld aluminum operators must take care to clean the base material and remove any aluminum oxide and hydrocarbon contamination from oils or cutting solvents. Aluminum oxide on the surface of the material melts at 3700 F while the base-material aluminum underneath will melt at 1200 F. Welding process for aluminum alloys. This can take a little while to learn since stick welding also known as Shield Metal Arc Welding or SMAW is known.
