FIELD: railways.
SUBSTANCE: group of inventions relates to the field of the upper structure of railway tracks, in particular, to methods for processing of welded rail joints, as well as to processed welded joints. The method consists in finishing grinding of a protruding part of an aluminothermic welded joint. After finishing grinding of a horizontal surface and side faces of a rail head, a neck, nibs, and a sole of the joint are additionally ground. The neck, nibs, and the sole of the welded joint are processed flush with the neck, nibs, and the sole of welded rails.
EFFECT: operation of rail joints is simplified.
