The flux-cored wires have been developed for submerged arc surfacing of working surfaces of rollers and plates of single- roller supporting members (SRSM) of bridges with a layer of high-strength steel of the 30Kh13MN grade, which is resistant to the atmospheric corrosion. The technology of manufacture of SRSM using surfacing allows their life to be extended 3 times to make it equal to the life of the bridge. Plants of the E.O. Paton Electric Welding Institute are manufacturing SRSM on the commercial scale
Keywords: surfacing, materials, bridges, single-roller supporting members, corrosion-resistant high-strength contact surfaces, technology, manufacturing
