Shielded Metal Arc Welding
Gleeson, Edgar
Shielded metal arc welding (SMAW) is an arc welding process, which uses a consumable flux-covered electrode to lay the weld. The flux coating disintegrates as the weld is laid, emitting vapors in the process which serve as a shield and provide a layer of slag that protects the weld area from atmospheric contamination. SMAW employs minimal equipment such as a welding power supply, an electrode with a holder, a ground clamp and welding cables. T...
