Phosphorus transfer behavior has been systematically investigated by submerged arc welding of EH36 shipbuilding steel with CaF₂–TiO₂–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 process with thermodynamic calculations, it is found that the major driving force enabling phosphorus transfer is largely governed by the activity difference between hypothetical P₂O₅ in the flux and that equilibrated with the weld metal.

CaF2-TiO2-CaO 助焊剂在 EH36 造船用钢中高热输入埋弧焊中的磷转移行为

_{通过 EH36 造船钢用 CaF 2} -TiO ₂ -CaO 焊剂进行埋弧焊，系统地研究了磷的转移行为。CaO含量高于15.7质量％时会引起脱磷；否则，可能会发生磷吸收。将实际焊接过程与热力学计算相结合，发现使磷转移的主要驱动力很大程度上取决于焊剂中假设的 P ₂ O ₅与焊接金属平衡的活性差异。
