The aim of the work is to create inductors for heat treatment of welded butt joints of railway and tram grooved rails. For thermal treatment of welded butt joints of railway rails, the inductors were proposed, located opposite each other on the two sides of a rail. Investigation of local heating of railway and tram grooved rails with a frequency of 2.4 kHz showed that inductors provide a uniform heating of cross-section elements of the rails, a low difference in temperature between the surface and deep layers of the metal in the head of the rails and a decrease in heating time from the workshop temperature to the normalization temperature. 8 Ref., 3 Fig.
