During surfacing of corrosion-resistant layer on the parts of power and chemical equipment it is often necessary to obtain
a specified chemical composition and properties of deposited metal already in the first layer. The influence of current,
voltage and deposition rate as well as the sizes of gap between the strips on the stability of electroslag process, geometric
dimensions of deposited beads and volume of base metal in the deposited metal were investigated. The range of
surfacing modes using two strips of stainless steel of 0.5x60 mm section was determined, in which a stable electroslag
process with a good formation of deposited metal and minimum penetration of the base metal in the range of 7–9 %,
= 1400–1500 A, Us
= 32–33 V and νd
= 14–17 m/h; 16 mm gap between the strips, is observed. The mechanical
properties of metal, deposited at these modes using strips ESAB OK Band 309LNb ESW and Sv-08Kh19N10G2B
under flux ESAB OK 10.10, are at a sufficiently high level and meet the requirements specified to them. The obtained
results may be used in selection or development of materials and technologies of anticorrosive surfacing of parts of
power and chemical equipment. 11 Ref., 4 Tables, 5 Figures.
