Question

The welding process which uses a blanket of fusible granular flux is

Correct answer (B) submerged arc welding Solution Submerged arc welding (SAW) is a welding process that 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. In the molten state, the flux becomes conductive and provides a current path between the electrode and the work. Turn this into a strength.
