摘要

MnO–SiO2–TiO2 fluxes have been designed to improve weldability for EH550 offshore engineering steel. It has been demonstrated that 40 mass pct TiO2 enables the weld metal to possess a yield strength of 593 MPa and an impact energy of 58.9 J. Such enhancement is directly attributed to TiO2-assisted element transfer, which suppresses Mn and Si contents while simultaneously reduces C loss by 0.0116 mass pct. Underlying mechanisms responsible for optimal weldability have been postulated.
