Submerge arc welding (SAW) – The arc is submerged beneath a blanket of flux. There are two welding consumable (Electrode wire and Flux). The electrode can be a solid wire or cored wire. The flux made form variety of minerals also generates a protective gas shield and slag (Also be used to add alloying elements to the weld pool) which protects and improve properties in the weld zone. A shielding gas has not required.
