Element Transfer Behaviors of Fused CaF2-SiO2 Fluxes Subject to High Heat Input Submerged Arc Welding

A series of fused CaF 2 -SiO 2 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 SiO 2 con...

Summary:A series of fused CaF 2 -SiO 2 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 SiO 2 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.
