TiO2-Assisted Microstructural Variations in the Weld Metal of EH36 Shipbuilding Steel Subject to High Heat Input Submerged Arc Welding

Two simple yet comparable fluxes, CaF 2 and CaF 2 –40 wt pct TiO 2 , have been employed to engineer shipbuilding steels under high heat input submerged arc welding, aiming to clarify the unique functions demonstrated by incurring TiO 2 addition. Compared with pure CaF 2 , TiO 2 -containing flux coul...

More Information
Summary:Two simple yet comparable fluxes, CaF 2 and CaF 2 –40 wt pct TiO 2 , have been employed to engineer shipbuilding steels under high heat input submerged arc welding, aiming to clarify the unique functions demonstrated by incurring TiO 2 addition. Compared with pure CaF 2 , TiO 2 -containing flux could increase columnar austenite width from 119.2 ± 18.1 to 201.5 ± 32.2  μ m. Furthermore, TiO 2 could significantly enhance acicular ferrite fraction, which has been primarily enabled by the formation of Ti-bearing inclusions.
