The article summarizes the 60-year experience of the E.O. Paton Electric Welding Institute in innovative solutions in the field of development of technologies and equipment for flash-butt welding of rails. Many of them are pioneering, which is confirmed by a number of licensing agreements with leading countries of the world. Today, the stock of flash-butt welding machines and complexes, operating throughout the world, designed at the PWI and manufactured by the Kakhovka Plant of Electric Welding Equipment, amounts to more than 2,500 units, which is about 60% of the global stock of machines. 13 Ref., 4 Tab., 22 Fig.
Keywords: flash-butt welding, rails, eutectoid and hypereutectoid steels, technologies and equipment, continuous flashing, pulsating flashing, heating simulation, long-length rail strings, tension welding, quality monitoring
