Exothermic welding is a modern technology, which by the chemical reaction(exothermic reaction) of aluminum and cupric oxide to produce the residue of high temperature liquid copper and alumina, and use the high temperature in the exothermic reaction to accomplish electric welding. This reaction was accomplished in the heat-resistant graphite mould, it only took a few seconds.
There is no need for extra energy, only welding powder will do. It’s easy to operate, and the welding is secure. The interface composition of metal is tiemolecule, so there is no corrosion.

Graphite exothermic welding mold refers to a tool used in the process of exothermic welding, which is a method of joining two metal parts using a chemical reaction. The mold, made of graphite material, is designed to hold the metal parts in place during the welding process and ensure that the weld joint is formed correctly.
