It is proposed to perform electroslag surfacing of end faces with application of current-supplying mould (CSM) and feeding large-section remelting electrode into its central part. Two variants of electric circuits of remelting electrode connection are proposed. In the first circuit the same potential is applied both to consumable and annular nonconsumable (CSM upper section) electrodes. In the second circuit, potentials of both the electrodes are different. The following technique of surfacing was proposed as a result of test surfacing performed with ANF-29 flux in CSM of 180 mm diameter with steel 40 electrodes of 40–130 mm diameter. After setting the slag pool in CSM, it is recommended to conduct the first stage (joining the base and deposited metal) with the first electric circuit. Electrode melting will be slower, but with optimum electric power applied to the slag pool through CSM, it is possible to achieve uniform penetration of base metal. Furtheron, at deposition of subsequent layers with higher efficiency and good quality of the deposited layer, one should proceed to the second electric circuit of remelting electrode connection. 8 Ref., 5 Figures.
