Submerged Arc Welding Fluxes - A Review

Arun Rehal, J S Randhawa

Abstract: Submerged arc welding; because of its inherent benefits such as higher metal deposition rate; good strength of the joint and good surface appearance; is extensively used in the fabrication of pressure vessels; pipe lines and off-shore structures. Welding flux constitutes nearly half of the cost in SAW process. Over the years; development of better welding flux compositions in terms of mechanical properties and productivity; which are economically cost effective too; has caught the eye of many researchers. In the present paper research work carried out by various researchers in the field of welding flux development has been reviewed.
