Exothermic welding is a simple, efficient, high quality metal joining technology, which uses metal compound chemical reaction heat as a heat source, through overheating (is reduced) molten metal, directly or indirectly heating the work, in a special graphite mold cavity to form a certain shape, size, meets the engineering needs of welded joints. Currently, the exothermic welding has been widely adopted to replace the mechanical connection between the method of the metal.
