Submerged Arc Welding Principles Submerged Arc Welding (SAW) uses heat generated by an arc formed when an electric current passes between a welding wire and the workpiece. The tip of the welding wire, the arc, and the weld joint are covered by a layer of granular flux. The heat gen-erated by the arc melts the wire, the base metal and the flux.Submerged Arc Welding (SAW): Equipment and ApplicationsSubmerged arc welding requires more thorough edge preparation and better fit-up than shielded metal arc welding. This is because in SAW a large molten metal pool is formed so if the fit-up is poor, the molten metal and slag may run out through gaps, thus affecting the weld quality.Stainless Steels Welding Guide - Lincoln ElectricWelding 9.2 Submerged Arc Welding 9.3 Gas Metal Arc Welding 9.4 Flux Cored Arc Welding 9.5 Gas Tungsten Arc Welding 10.0 Procedures for Welding Stainless Steels weld 1035 introduction to gas metal arc welding Submerged arc welding..21 10.1 Welding with the Shielded Metal Arc Process 10.2 Welding with the Submerged Arc Process 10.3 Welding with the Gas Metal Arc Process 10.4 Welding with the Gas Tungsten Arc weld 1035 introduction to gas metal arc welding Submerged arc welding
