The results presented were on experiments of effect of different technological parameters on formation of metal pool at electroslag surfacing with discrete filler or electrode or non-conducting billet of large section in current-supplying mould.  It is determined that shape of the metal pool can be effected by means of variation of electrical mode of the process, electrical scheme of connection of current-supplying mould using direct and alternating current. The ways for obtaining a correct shape of the metal pool at increased productivity of electroslag process were shown. 8 Ref. , 2 Tabl., 2 Fig.
