FLASH BUTT WELDING OF HEAVY DUTY RAILS -- LABORATORY SIMULATION AND ON SITE EXPERIENCE

The technique has been used to assess the weldability of new rail steels, processed on laboratory scale, in terms of the amount of martensite which forms in the heat affected zone of welds and the maximum hardness values in this zone. Use of the data has been made in modifying the standard flash butt welding procedure to produce metallurgically satisfactory welds.
