A series of fused CaF2-SiO2 binary fluxes have been developed to investigate element transfer behaviors under high heat input submerged arc welding. Transfer of elements is quantified by Δ quantities, which demonstrate respective contributions from the flux to the weld metal. Effects of SiO2 contents on the transfer of Si, Mn, and O have been thoroughly evaluated. Thermodynamic considerations have been attempted for constraining chemical reactions and mechanisms involved in welding.

高热输入埋弧焊条件下熔融CaF2-SiO2焊剂的元素转移行为

已经开发了一系列熔融 CaF2-SiO2 二元焊剂来研究高热输入埋弧焊下的元素转移行为。元素的转移通过 Δ 量来量化，这表明了焊剂对焊缝金属的各自贡献。SiO2 含量对 Si、Mn 和 O 转移的影响已得到彻底评估。已经尝试考虑热力学来限制焊接中涉及的化学反应和机制。
