Train rails are joined together via a seriously awesome process called exothermic welding, which basically involves lighting off a chemical called Thermite and sending molten iron into a sand ...

Regardless of the process used (thermite welding or flash welding), the completed rail joint must be dressed using grinders to ensure a proper running surface and gage surface for train wheels. Figure ...

The thermite process is a handy way to generate molten iron in the field. It’s the reaction between aluminium metal and iron oxide, which results in aluminium oxide and metallic iron. It&#821… ...

THE Goldschmidt thermite process has now become so firmly established in various industries, that we accept it more or less as a matter of course, and have almost ceased to be stirred by the ...

One of thermite’s first uses was connecting railroad tracks, and it’s still used for that purpose today. Here’s a great video of the thermite welding process in action.

Pandrol North America is working to bring welding from “the stone ages to the modern ages,” according to Dave Manoleff, Manager of ATW. One way to do this is to speed the thermite welding process—a ...

During the International Exhibition for Track Technology from 28 to 30 May 2013 in Münster, Germany, the Goldschmidt Thermit Group will present its SMARTWELDCONTROL. It is a specially designed tool ...
