- Abstract
Fused CaF2-SiO2-CaO-TiO2 fluxes are designed and applied to join EH36 shipbuilding steel under high heat input submerged arc welding. Pertinent elemental transfer behaviors of major alloying elements are quantified and possible chemical reactions have been postulated. It is found that transfer of Si and O is enhanced by increasing TiO2 addition, although that of Si is concurrently dependent on SiO2 activity. Furthermore, a unique neutral point is identified with regard to Ti transfer.
