The influence of different circuits of electrode connection to one or two d.c. power sources on base metal penetration was studied at electroslag surfacing of end faces. It is established that circuits of electrode connection both to one and to two d.c. power sources can be applied to produce a minimum and uniform penetration. Reduction of the distance of the processed surface (electrode end face) relative to the current-conducting section of the current-supplying mould leads to increase of deposition efficiency and to reduction of the specific power consumption. 12 Ref., 1 Tabl., 3 Fig.
