Studied was a nature of change of electrotechnical parameters of process of discrete filler melting in its portion feed and variation of thickness of deposited metal in a stationary current-supplying mould. It is determined that the process of melting in a slag pool is effected by initial values of depth and specific electric conductivity of the slag pool. A concept of averaged heat level of the slag pool was introduced. It characterizes change of physical properties and thermal state of the pool as a result of feed in it of a portion of discrete filler and allows optimizing initial position of deposited surface relatively to current-supplying section of the mould. 5 Ref., 1 Table, 5 Figures.
Keywords: electroslag surfacing, stationary current-supplying mould, deposited metal thickness, slag pool depth
