Abstract

This paper presents the scientific and technological principles of electrochemical removal of diffusible hydrogen by reactions of hydroxyl and hydrogen in molten aluminum fluoride slag and in the gas phase. A model was proposed for the electrochemical processes in the weld pool with the formation of aluminum fluoride polymer clusters in TiO₂–CaF₂–Na₃AlF₆ slag to reduce the content of diffusible hydrogen, decrease the volume of slag inclusions, and improve the mechanical properties of bainitic steel welded joints.
