Possible chemical and electrochemical reactions have been postulated to analyze alloying element transfer behaviors. The decomposition of ZrO2 during SAW has been validated by applying the gas–slag–metal equilibrium model and the O supply capacity of ZrO2 has been quantified. For the entire compositional range, O content has been controlled within a well-maintained range from 220 to 400 ppm, and the transferred quantity of Zr content reaches to the maximum value of 120 ppm. It is further demonstrated that ZrO2 addition incurs appreciable Si loss within the weld metal.en© The Minerals, Metals & Materials Society and ASM International 2024.
