Regulation effect of external electric field inducing oxygen flow on molten slag oxidation in submerged arc welding

During submerged arc welding, the direct current external electric field between molten slag and liquid metal was applied behind the arc to induce directional migration for free oxygen ion, so as to regulate electrochemical oxidation behavior with no change basicity index of molten slag. The variati...
