Products Description
The installation of railway steel rails is a critical part of track engineering, requiring smoothness, stability, and safety. During installation, rails must be laid on sleepers according to standard gauge and fixed through a fastener system. To reduce the impact and wear caused by rail joints and improve the smoothness of train operation, modern railways widely use long rails or seamless track systems.
This involves rail welding technologies such as flash welding, thermite welding, and gas pressure welding. Among them, flash welding is currently the most commonly used on-site welding method, featuring advantages such as high weld strength and stable quality. Thermite welding is often used for maintenance and short rail welding due to its flexible and convenient operation. After welding, the welds must also be ground and smoothed to ensure track continuity and geometric accuracy. Advanced rail welding technologies provide a reliable guarantee for railway operations.
