Title: A Review Study
of Submerged Arc welding Fluxes
Author Name: Ajay Kumar, Hari Singh , Sachin Maheshwaric
Synopsis:
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, SiO2 and Al2O3 basic
elements and with the minor addition of MnO, CaF2, NiO, MgO and Fe-Cr are
chosen as variables. 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.
