S.A.W Wire And Flux
Submerged arc welding (SAW) is a common arc welding process. It requires a continuously fed consumable solid
or tubular (flux cored) electrode. The molten weld and the arc zone are protected from atmospheric contamination
by being “submerged” under a blanket of granular fusible flux consisting of lime, silica, manganese oxide, calcium
fluoride, and other compounds. When molten, the flux becomes conductive, and provides a current path between
the electrode and the work. This thick layer of flux completely covers the molten metal thus preventing spatter and
sparks as well as suppressing the intense ultraviolet radiation and fumes that are a part of the shielded metal arc
welding (SMAW) process.
