In most heavy-duty railways of Ukraine, flash-butt welding is the dominant process for joining rails. Welding is performed
in special shops and in field conditions during the construction of new main lines and repair of existing railways.
Technologies and equipment are constantly being improved in connection with the use in the railways of Ukraine and
other countries of the world, of new generations of high-strength rails with an increased wear resistance, in accordance
with the requirements to high-speed main lines. In the last decade, the developed countries of the world are revising
the basic standards governing the quality of rail steels and requirements to mechanical properties of rail welded joints,
taking into account their use on heavy-duty and high-speed main lines. One of the specified tasks is the adaptation of the
Ukrainian standard TU U 24.1-40075815-002: 2016 (for stationary and mobile welding machines), which determines
the requirements to the quality of welded joints of high-strength rails, to the valid European standard EN 14587-1 2007
(for stationary welding machines) and EN 14587-2 2009 (for mobile welding machines). 9 Ref., 4 Tables, 12 Figures.
