Exothermic welding was founded at the end of the 19th century when H. Goldschmidt discovered aluminum powder and metal oxides can be caused by an external heat source to start an exothermic reaction, and once the reaction can continue by itself, the general formula of this reaction is: metal oxide + aluminum (powder) → alumina + metal + thermal energy Exothermic welding can mainly weld such as pure copper, brass, bronze, red copper, copper-clad steel, pure iron, stainless steel, wrought iron, galvanized steel, cast iron, etc.     Today, let's discuss the application of  aluminothermic welding  on crane rails.   Usefully, The crane is a double-girder structure, the crane rails run on the tracks of the main girder bridge. The rails of the main beams designed in China are generally mechanically in segmented and gaped connection, In the other words, they are ground or processed at the interface according to the length of the supply, they are formed by close joints. The rail welding met
