How Aluminothermic Rail Welding Works
Aluminothermic rail welding (also known as thermite welding) forms a permanent, high-strength joint by using the exothermic reaction between aluminum powder and iron oxide. The reaction generates molten steel, which flows into a sealed mould around the rail ends, fusing them into a continuous track after cooling. This process is widely used in railway, metro, and industrial track projects thanks to its reliability and minimal equipment requirements.
Step-by-Step Welding Process
- Align the rails
Position and correct the rail ends to make sure they sit in the right geometry. - Set the rail gap
Adjust the required gap for the aluminothermic welding process. - Clean the rail ends
Remove rust, dirt, and oil to ensure proper bonding. - Install the mould
Clamp the sand mould around the rail ends and seal it with sealing sand. - Preheat
Use the preheater to heat the rail ends and mould to the required temperature. - Prepare the crucible
Mount and preheat the disposable crucible on the bracket. - Ignite the thermite
Light the thermite portion; molten steel forms inside the crucible. - Pour the molten steel
The molten steel flows into the mould and fills the rail gap. - Cool and remove slag
Let the weld cool, then remove slag and trim the joint. - Finish the weld
Grind the rail head to restore the running profile.
