... avoided; otherwise, the full benefit of the inert gas shielding may be lost. Submerged arc welding (SAW) employs a consumable electrode immersed in a conductive flux that acts as a protective shield from the atmosphere. The arc is struck through the flux, and gravity deposits the molten metal to the...
