FIELD: processes for welding railway road, tram and other rails made of carbon steel or alloy steels.
SUBSTANCE: method comprises steps of mechanical working of rails ends in such a way that to make them normal relative to rail axes; applying onto rails ends anti-oxidizing and anti-decarbonizing film having thickness 0.1 - 0.5 mm; heating rails and welding them under pressure. Usage of anti-oxidizing and anti-decarbonizing film allows reduce waste caused by fin occurring at welding and lower by 40 -60% labor consumption of next operations for working welded seam.
EFFECT: improved efficiency of method, lowered waste quantity.
