Producing minimum and uniform penetration of base metal at electroslag surfacing of end faces by consumable electrode of a large cross-section is a complex task. The most promising is the application of nonconsumable electrode – current-supplying mould for these purposes. Influence of different electric circuits of connection of electrodes of different diameter from one or two AC power sources on base metal penetration was studied. It is found that from the viewpoint of optimizing the surfacing technology (achievement of not only quality indices, but also increased process efficiency), it is promising to apply the surfacing circuit with one power source and the same potentials on the bottom plate and current-conducting section of the current-supplying mould. Circuit of electroslag surfacing with two sources allows producing similar results, but it is more complicated to implement (presence of two sources) and less cost-effective, respectively. Obtained results can make up the data bank for designing a system of automatic regulation of base metal penetration at electroslag surfacing of end faces. 11 Ref., 1 Table, 3 Figures.
