Submerged arc welding has been performed by employing fused CaO-SiO₂-MnO fluxes of varying MnO and CaO contents on EH36 shipbuilding steel grade. Transfer levels of O, Si, and Mn between fluxes and weld metals have been quantified and evaluated from thermodynamic perspectives. The results show that both slag-metal and gas-slag-metal equilibrium considerations are capable of placing limits on the direction and amount of element transferred between fluxes and weld metals.

熔融 CaO-SiO2-MnO 焊剂在高热输入埋弧焊中元素传递行为的热力学评价

埋弧焊已通过在 EH36 造船钢等级上使用不同 MnO 和 CaO 含量的熔融 CaO-SiO ₂ -MnO 焊剂进行。焊剂和焊接金属之间的 O、Si 和 Mn 的转移水平已经从热力学角度进行了量化和评估。结果表明，渣-金属和气体-渣-金属平衡的考虑都能够限制焊剂和焊缝金属之间转移的元素的方向和数量。
