Rail welding has begun at the RSP-M rail welding enterprise for the future Moscow – St. Petersburg high-speed railway. The process begins with the incoming inspection of 100-meter rails, each weighing 6.5 tons, which are fed onto the conveyor.
Eight 100-meter rails are welded into one rail. This operation is necessary to minimize joint connections during the laying of high-speed railway tracks and will ensure maximum smoothness and safety of the train's movement. Rail welding takes place simultaneously on two lines by one shift team, the estimated capacity of RSP-1 is 650 km of welded rails per year.
The first stage of welding includes electric welding, in which an electric arc arises between the ends of the rails, melting the metal. Under pressure, the rails are fused, after which the welded rail is sent to the rough grinding and hardening station. During hardening, the weld is heated to 945 degrees and abruptly cooled with air. This ensures the strength of the connection. The process is completed by fine automatic grinding and final flaw detection of the welded tracks to confirm the quality of the products.
Currently, the enterprise has already received 7,000 tons of rails, which, after being welded into rails, will be sent to the laying site. This will speed up the construction of the highway.
Earlier www1.ru reported that the production of a high-speed train for the HSR has started at Ural Locomotives.
