Modelling of Slag Produced in Submerged Arc Welding

Abstract

This study has been conducted to reveal the effects of flux composition on slag produced and wire consumption. RSM was used for designing the experiments. Mathematical modeling was done for the output in terms of flux composition. The study reveals that the slag produced is dependent upon the basicity index of the flux and CaF2 used as a flux ingredients. Fluxes were made by agglomeration technique. CaF2, FeMn, NiO were added to study their effect on slag produced and bead geometry. The elements transferred to the welds from the flux were also found to have significant effect on slag produced and properties of weldments.
