Insider's Guide to Submerged Arc Welding (SAW) - …

Submerged arc welding (SAW) is a type of arc welding process. It uses the heat generated by an arc struck between the continuously fed bare electrode and the workpiece for melting the surface of the workpiece metal and the wire electrode to create a molten weld pool. The arc is maintained automatically. The melted wire electrode is added to the molten weld pool, forming the weld metal on cooling.
