The effect of increasing the distance from the processed surface to the current-supplying mould on base metal penetration, deposition rate and specific power consumption was studied at electroslag surfacing of end faces with application of non-conducting billets. Comparison of this effect on the quality of bimetal produced in electroslag surfacing with electrodes and non-conducting billets of the same cross-section was performed. It is found that application of optimal electric power to the slag pool through current-conducting section of current-supplying mould and of consumables billets allows achieving the set penetration of base metal, good formation of the deposited layer and process efficiency, commensurate with those obtained at surfacing with electrode of the same cross-section, only in the case of optimum distance from the melted end face of the consumable billet to the processed surface of the item. 13 Ref., 1 Tabl., 2 Fig.
