Most modern railway systems use long rails or seamless lines to reduce the number of joints and improve the smoothness and stability of the track. This requires high-quality rail welding technology. Common welding methods include flash welding, hot melt welding, gas pressure welding, etc. During the welding process, it is necessary to control the temperature, pressure and cooling rate to ensure that the weld strength is not lower than that of the parent material.
When laying rails, professional track laying equipment must be used to ensure that the alignment, verticality and linearity of the rails meet the design standards. After installation, stress release treatment is also required to prevent deformation caused by thermal expansion and contraction of the rails. High-quality welding and scientific laying technology are important guarantees for ensuring the long-term reliability of railway operation.
