Phosphorus transfer behavior has been systematically investigated by submerged arc welding of EH36 shipbuilding steel with CaF 2 –TiO 2 –CaO fluxes. Dephosphorization could be induced when the CaO content is higher than 15.7 mass pct; otherwise, phosphorus uptake may occur. Coupling actual welding p...
