Railroad thermite welding
WebThermite welding is widely used to weld railroad rails. The weld quality of chemically pure thermite is low due to the low heat penetration into the joining metals and the very low carbon and alloy content in the nearly pure molten iron. To obtain high-quality railroad welds, the ends of the rail being thermite welded is usually preheated with ... WebThe Process of Thermit Welding. Thermit welding is an effective, highly mobile, method of joining heavy section steel structures such as rails. Essentially a casting process, the high heat input and metallurgical properties of the Thermit steel make the process ideal for welding high strength, high hardness steels such as those used for modern rails.
