Weld metal microstructures of EH36 shipbuilding steel, processed by electro-gas welding with varying CaF₂–SiO₂ flux-cored wires, have been investigated. Quantified data indicate that introducing SiO₂ leads to an appreciable uptake of acicular ferrite fraction and a simultaneous decrease in bainite. Such microstructural evolution has been primarily attributed to the reduced levels of C and Mn (from 0.151 to 0.137 wt pct and 2.058 to 1.744 wt pct, respectively), which are primarily enabled by SiO₂ decomposition.
