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.sp.info 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. The distinct feature of the submerged arc welding is that it uses a continuous flow of powder…See more on workshopinsider.comsp.info Where can I find guidance for steel bridge fabrication?Guidance on the design for economic fabrication of bridges is available in BCSA publication Steel Bridges, Chapter 7 - Costs.See all results for this questionsp.info How is nitrogen used in the welding of stainless steel?Nitrogen is added to provide strength and also aids in weldability.
