Abstract
Multilayer building-up of worn surfaces of girder tram rails with austenitic wires of PP-06Kh15G15N2MF type is used to demonstrate that deposition of the first bead by one arc with 28-30 kJ/cm heat input prevents tears formation in the HAZ metal of difficult-to-weld high-carbon steel M-76.
Keywords: building-up, wear, reconditioning, HAZ metal, tears, twinand single-arc processes, thermal cycles, structure, hardness
