The paper presents the concept of bulk and surface heat treatment of the welded butt joint of a railway rail by two or more inductors with the purpose of achieving favourable phase transformations of metal and normalizing its structure in the weld zone. Performed computations and experiments resulted in development of split inductors without magnetic circuits, which allow performance of bulk and surface induction heat treatment. Conducted experiments on heating a welded butt joint of a rail by the developed split inductors without the magnet cores demonstrated heating uniformity characteristics acceptable for bulk heat treatment of rails, limit temperatures and rates of heating of the main rail working areas both on the surface and in-depth of a narrow heating zone. 19 Ref. 2 Tables, 8 Figures.
