Exothermic Welded Connection Procedure
　　Exothermic Welded Connection makes use of the high-temperature welding liquid created by chemical reaction to realize the welded procedure of the welded connection between high-performance electrical materials．
　　Therefore, Exothermic Welded Connection requires no external power or heat source. Its whole reaction process is carried on in a special welding mould, so it's safe and speedy.
　　 The welding mould for Exothermic Welded Connection Procedure is made up of high-temperature resistant and semi-perdurability graphite; it can endure superbly high temperature's welding.
　　 Welding mould includes mould cave, injection hole, welding powder tube and etc., and the shape, size of mould cave and the flow direction of the welded metal are all be tightly designed according to the practical connection requirements, thus the connectors made by Exothermic Welded Connection Procedure have beautiful appearance and also uniformly neat.

　　Exothermic Welded Connection mainly uses in welding red copper, brass, bronze, pure copper, copper and steel, pure iron, stainless steel, wrought iron, zincified steel, cast iron and etc.
　　 The advantages of Exothermic Welded Connection Procedure:
1. The connector points are of molecular bond, so it won't loosen, worsen, and be corroded.
2. The materials of connector and conductor are identical, they have the same electricitycapability, but the connector rises less temperature than the conductor.
3. Same as the conduct, the weld point can also endure the assault of repeated strong current (when accident) without fusing.
4. The equipment is portable and suitable for field welding work.
5. The speed of welding is very rapid, it can save labor force.
6. The method of work is very easy, so it do not need professional welding worker.
7. As the connectors of welding connection are in uniform shape, so it's easy for quality control.
8. The total heat quantity is less than any other welding methods, hence it do less destroy towards the insulator, and can save insulating materials.
