Behind the Scenes - Thermite Welding

Recommended Posts

The Confederation Line track rails were joined by two welding techniques. Thermite Welding and Flash Butt Welding.

Generally, thermite welding is done on site, while flash butt welding is done before rails are moved to the site.

Thermite welding (or exothermic welding) is a process in which molten steel is poured into a cast placed around a cross section of rail. Through a exothermic reaction between aluminum and iron oxides, molton steel is created.

Flash butt welding is a forged weld created by an electrical charge between the cross sections of rail until the steel is malleable. In this method, no material is inserted between the sections of rail.
