Joining of dissimilar and different diameter metals by friction welding for railways.
Strongly bonding dissimilar metals to contribute to the durability of railway structures.
In the railway industry, components with high durability are required to balance safety and long-term operation. Particularly at the joints of rails and wheels used in harsh environments, high strength and wear resistance are essential. Deterioration of these joints can lead to serious accidents and increase the costs associated with regular maintenance and replacement. Our friction stir welding technology firmly joins dissimilar metals, achieving high durability and enhancing the safety and economic efficiency of railway structures. 【Application Scenarios】 - Joining rails to rails - Joining wheels to axles - Joining components of overhead wires and signaling equipment 【Benefits of Implementation】 - Improved safety through increased joint strength - Cost reduction by minimizing material loss - Reduced operational costs by decreasing maintenance frequency
