FIELD: machine building.
SUBSTANCE: invention relates to repair of operational damages of rolling surface of railway rail head and is used for repair of railway rail laid on tracks of railway transport, trams, metro trains and on crane ways. Proposed method comprises cleaning of damaged surface with defect, heating of stripped section, layer-by-layer surfacing of cleaned section, natural cooling and machining of built-up surface. In zone, width of which exceeds width of weld zone by 250 mm, heating is performed, at that roller is welded on starting and ending on side of non-working face of rail on three sides of perimeter of repaired damage, then re-depositing roller along entire perimeter of repaired damage.
EFFECT: repair of electric rail surfacing of railway rails from high-carbon medium alloyed steel with weight content of chromium content to 1,25 %.
