Field Welding Services
Exothermic (Thermite) Welding for Railroad Tracks
Northern Rail Services is very experienced at joining train rails using a process called exothermic welding. This process, called Field Welding, involves lighting off a chemical called Thermite and directing liquified iron into a mould. There are multiple methods for joining train rails, but a huge advantage of field welding is it does not require electricity so it can be done practically anywhere.
