What is Submerged Arc Welding (SAW)?
Submerged Arc Welding (SAW) is a welding process where an electric arc forms between a continuously fed electrode and the workpiece. This arc is covered by a layer of powdered flux, which, when melted, conducts electricity between the electrode and the metal being welded. The flux also produces a protective gas shield and a layer of slag, both of which safeguard the weld area.
