Railway Applications - Infrastructure - Flash Butt Welding of Rails - Part 2: New R200, R220, R260, R260Mn, R320Cr, R350HT, R350LHT, R370CrHT and R400HT Grade Rails by Mobile Welding Machines at Sites Other Than a Fixed Plant
Also Known As:
The DIN EN 14587-2 standard focuses on the flash butt welding of rails in railway infrastructure. Specifically, it pertains to the use of mobile welding machines at sites other than a fixed plant. This standard sets requirements for the approval of the welding process using a mobile flash butt welding (MFBW) machine, as well as the welding contractor and subsequent welding production.
The standard applies to new rails of various grades, including R200, R220, R260, R260Mn, R320Cr, R350HT, R350LHT, R370CrHT, and R400HT. These rails should be Vignole type and weigh 46 kg/m or more, as defined in EN 13674-1. The welding process described in this standard is intended to be used for the fusion of rails into welded strings.
It is worth noting that the requirements outlined in this standard also apply when a MFBW machine is used in a static but temporary situation. This ensures that the welding process meets the necessary criteria for quality and reliability, regardless of the specific site conditions.
