Abstract
The influence of different circuits of electrode connection to one or two DC power sources on base metal penetration at electroslag surfacing of end faces was studied. It is established that the circuits of electrode connection both to one and two DC power sources can be used to obtain minimum and uniform penetration. Shortening of the distance from the processed surface (billet end face) to the current-conducting section of current-supplying mould leads to an increase of surfacing efficiency and reduction of specific power consumption. 12 Ref., 1 Table, 3 Figures.
Keywords: electroslag surfacing of end faces, large-section electrode, current-supplying mould, DC power sources, processed surface, base metal penetration
