The Thermit reaction was discovered in 1893 by Prof. Hans Goldschmidt, a German chemist, and patented in 1895. In 1899 the first commercial application of Thermit was the welding of Tram tracks in Essen, Germany. Aluminothermic welding has made pioneered the installation of continuous welded rails by uniformly uniting the railway track ends and is the fastest method of joining large pieces of steel. It is essentially a “portable foundry” and can be used in any location. Thermitrex (Pty) Ltd in Boksburg East, Gauteng, RSA was established in 1971. It is a member of Goldschmidt-Thermit Group a multinational company with 23 subsidiaries located worldwide and its headquarters are located in Leipzig, Germany. Thermitrex has a foundry located on the company premises, which manufactures ferro-alloys that is used as a raw material in the Aluminothermic mixture. The ferro-alloys are exported to sister companies worldwide.
