Shielded Carbon-Arc Welding Aluminum

The shielded carbon-arc welding process can be used in joining aluminum. It requires flux and produces welds of the same appearance, soundness, and structure as those produced by either oxyacetylene or oxyhydrogen welding. Shielded carbon-arc welding is done both manually and automatically. A carbon arc is used as a source of heat while filler metal … Read more

Arc Welding Processes (SMAW)

(1) The core of the covered electrode consists of either a solid metal rod of drawn or cast material or one fabricated by encasing metal powders in a metallic sheath. The core rod conducts the electric current to the arc and provides filler metal for the joint. The electrode covering shields the molten metal from … Read more

Arc Welding Equipment (SMAW)

The equipment needed for shielded metal arc welding is much less complex than that needed for other arc welding processes. Manual welding equipment includes a power source (transformer, dc generator, or dc rectifier), electrode holder, cables, connectors, chipping hammer, wire brush, and electrodes. Arc Welding Parameters. (1) Welding voltage, current, and travel speed are very … Read more

Shielded Metal Arc Welding (SMAW)

Shielded Metal Arc welding is the most widely used method for general welding applications. It is also referred to as metallic arc, manual metal-arc, or stick-electrode welding. It is an arc welding process in which the joining of metals is produced by heat from an electric arc that is maintained between the tip of a covered … Read more

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
