Exothermic Welding Powder using reducible metal compounds and reducing substances in certain proportion and made through a special process. The prowder is non-dangerous goods, physical properties, can be used in any mode of transport.
The exothermic welding powder is to melt the metal conductor through the high temperature produced by the oxidized metals in the reductive flux during the exothermic reducing reaction.
Exothermic Welding Powder is also called aluminium heat welding powder.Use proper exothermic fluxes to make the connection joints more solid and extend the using life.

Exothermic welding feature:
1. Current carrying capability from welding point is same as conductor with good conducting performance. After inspection, the DC resistance ratio and change rate are almost zero before and after welding. This is the level that any of the traditional welding method cannot be compared.
2. No need of resources from outside. It can be operated indoor and outdoor.
3. It won't be damaged by surge current. The test shows the conductor will be melted earlier than welding points when under high current impact in short period.
4. Corrosion or slack will not be produced from welding. As it is weld junction,no contact surface, no residual stress, junction is stable and reliable as long term conductive body.
5. As it is welding junction, connector and conductor are combined on molecular.So it has a good mechanical strength and is a permanent junction.
6. Equipment is simple, convenient and handy. The operation is easy and can be done.
