Results of experiments were presented on study of the effect of different technological parameters on the formation of a metal pool in electroslag surfacing with a discrete filler either in the form of electrode or no-current large-section billet in current-supplying mould. It was found that the metal pool shape can be affected by changing the electric mode of the process, electrical scheme of connection of the current-supplying mould using direct and alternating current. The ways of producing a favorable metal pool shape at increased efficiency of the electroslag process are shown. 8 Ref., 2 Tables, 2 Figures.
Keywords: circumferential and edge electroslag surfacing, current-supplying mould, metal pool
