Exothermic welding is a simple, high efficiency and high quality method of metal connecting.

Lihe exothermic welding is a high temperature reaction of powdered copper oxide and aluminum. The chemical equation is 2Cu2O+2Al=6Cu+Al2O3 ( the temperature can be in excess of 2500°C.) It is a method of welding copper, iron, steel and ferroalloy without outside power.

In order to weld different sizes conductor, a graphite mold is needed. It is only to put the conductor need welding in the mold, dump powder into the mold, ignite the starting powder, than the reaction takes place. Open the mold when it is cold, thus the conductor connection is finished. We supply different connections and the matched mold and welding powder.

Characteristics

Good current loading ability

The welding point current loading ability is the same as conductor.

Good mechanical performance

The connection is a molecular connection. It is a permanent connection.

Stable dash current resistance

The test shows that in the surge of big current in short time, the conductor melts earlier than the connection point, so it will not be damaged by surge current.

Good resistance to corrosion

The welding point is covered by copper, it provides good resistance to corrosion.

Simple and safe connection

Neither outside power nor facility is required. It requires very little time to finish one welding. It can be done both indoor and outdoor.

Free control the reaction temperature

Different welding powder is provided according to the metal features, so the welding powder can be very solid.

Making a exothermic welding connection

Make sure the mold is dry, by pre-heating, put the cleaned conductors in mold.Place metal disc in bottom of mold crucible and close the mold.Dump welding powder into crucible, and place starting powder in the ignition pocket.Close lid, ignite the starting powder with the flint gun.Reaction takes place in the graphite mold.Open the lid when it is cold. The welding connection is done.
