Thermite Welding

 

Thermite welding uses an exothermic chemical reaction process to weld components together. A metal powder which releases a great deal of energy (highly exothermic) when reacting with oxygen, is combined with the metal oxide with a much lower heat of formation. An example of a thermite welding process; powdered mixtures of aluminum metal and iron oxide are loaded into the weld seam or joint and ignited. The aluminum strips the oxygen away from the iron oxide leaving behind a deposit of iron and aluminum oxide.
