Технология и оборудование для контактной сварки высокопрочных рельсов

Abstract

The problems of weldability of heat-hardened rails of modern production using the flash-butt welding method, development of technologies and equipment for their joining have been considered. It was shown that some uncontrollable impurities in rail steels deteriorate their weldability. The technology and equipment for welding of heat-hardened rails have been developed, providing the mechanical properties of welded joints on required standards.
