Submerged Arc Welding Submerged Arc Welding (SAW) is a joining process that involves the formation of an electric arc between a continuously fed electrode and the workpiece to be welded. A blanket of powdered flux surrounds and covers the arc and, when molten, provides electrical conduction between the metal to be joined and the electrode. #welding #metallurgy #metallurgicalengineering #materialsengineering #materialscience | Metallurgical engineering
