- Abstract
CaF2-SiO2-CaO-TiO2 fluxes have been designed and employed to submerged arc weld EH36 shipbuilding steel. Pathways for O gain and loss of weld metal have been quantitatively evaluated. Results revealed that O gain and loss increase with higher TiO2 content, but the value of O gain is slightly greater than that of O loss, resulting in a net increase for weld metal O. Such findings yield a fine-tuned strategy for formulating fluxes with lower O potential.
