Rigid rail is an important component of railway turnouts and is one of the many railway accessories. When using steel rails, welding treatment is required. There are different welding methods for welding steel rails, such as arc welding, gas pressure welding, flash welding, and aluminum thermal welding. Each of these rail welding methods has its own characteristics. In order to increase everyone's doubts and gain more relevant information, the rail pressing plate manufacturer will summarize and explain this issue.

1. There are methods of arc welding, such as forced forming arc welding and automatic narrow gap active gas shielded welding. The static bending, hammer drop, fatigue, and mechanical properties of rail arc welded joints exceed those of aluminum thermal welded joints, and are close to the joint performance of flash welding and pressure welding.

2. Pressure welding has no casting structure in the welding area, a small temperature gradient in the joint, and very low crack sensitivity. It does not require high-power power points and is mainly used for on-site joint welding.

3. Flash welding is widely used. Depending on the welding process, rail flash welding can be divided into intermittent preheating flash welding and continuous flash welding. Among them, continuous flash welding is more energy-saving, process stability, and joint reliability than intermittent flash welding. 4. Aluminum thermal welding does not require a power source, has simple equipment, fast welding speed, and low processing cost, making it particularly suitable for field operations.

The above is the characteristics of rail welding methods. We hope that everyone can use this information to increase their understanding of rail welding and the characteristics of each welding method.
