Principle of the process
Submerged-arc welding (SAW) involves the formation of an arc between a continuously fed wire and the workpiece. A blanket of powdered flux creates a protective gas shield and a slag for the weld zone. A shielding gas is not required. The arc is submerged beneath the flux blanket and is not normally visible during welding.
SAW is normally operated in the automatic or semi-automatic mode. The process is normally limited to the flat or horizontal-fillet welding positions.
