In this paper, the work done by previous investigators for the development of new agglomerated flux used during submerged arc welding process is reviewed, and the gaps are identified. The new fluxes are developed by using CaO, SiO and Al O basic elements and with the minor addition of MnO, CaF , NiO, MgO and Fe-Cr are chosen as variables. 2 2 3 2 The effect of variable flux constituents on weld metal are analyzed in the light of mechanical properties, bead morphology, element transfer analysis and physical properties by using response surface methodology technique. The results indicate that the newly developed flux behavior is at par of commercial fluxes.
