The E.O. Paton Electric Welding Institute together with the E.O. Paton Chinese-Ukrainian Institute of Welding and the SPC «PLAZER» developed the equipment and technology for anticorrosion electroslag surfacing applying strips. The effect of current, voltage and surfacing speed as well as the gap between the strips on the stability of electroslag process, geometric dimensions of deposited beads and volume of base metal in the deposited one were investigated. In the experiments the stainless strips ESAB 309LNb ESW with the cross-section of 0.5?60 mm and the flux ESAB OK 10.10 were used. The range of surfacing modes applying two strips was determined, providing a high efficiency and a stable electroslag process with a good formation of deposited metal and a minimal penetration of the base one in the ranges of 7–9 %: Is = 1400–1500 A; Us = 32–33 V; vs = 14–17 m/h; the gap between the strips is 16 mm. The mechanical properties of the metal deposited at these modes applying the strips ESAB 309LNb ESW under the flux ESAB OK 10.10 are at the level of mechanical properties of steel 309LNb. The obtained results can be used in selection or development of materials and technologies for anticorrosion surfacing of parts of power and chemical equipment. 7 Ref., 1 Table, 6 Figures.
