Chemical reactions during submerged arc welding with FeO-MnO-SiO2 fluxes
TL;DR: In this paper, the compositional changes of fluxes and weld metal during submerged arc flux welding with a series of synthetic MnO-FeO-SiO2 model fluxes containing 40 wt pct SiO2 and different ratios of MnO to FeO. Mechanisms for transfer of Mn, O, Si, C, S, and P are discussed in terms of the thermodynamic driving forces and kinetic factors such as diffusion, nucleation, and segregation.
