Exothermic welding powder

Features: *The process is absolutely safe therefore requires no special protection. *Requires the operator of no professional

Exothermic welding  introduction                                       

The Jsbound Exothermic welding process is a simple, self-contained method of forming high quality electrical connections. The compact process requiresno external power or heat source, making it completely portable.Connections are made inside a semi-permanent graphite mold using the high temperature reaction of powdered copper oxide and aluminum.

Exothermic welding Feature                                              

1.The operation is safe and there is no need for professional skill or special protection, so it is quite easy with equipped tools.

2.It's don't need other energy , convenient carrying, high operating efficiency.

3.The connector uses metallic copper of high purity which has strong resistance of corrosion.

4.The standard welding flux for grounding system

This is how it works                                                          

The Mold (1) features a Crucible (2), a Tap Hole (3) and a Weld Cavity (4).The Conductors (5) and (6) to be joined, are located in the Weld Cavity as shown, and the Mold is closed. A steel Retaining Disc (7)is located in the bottom of the crucible, to retain the Weld Powder (8) and Starting Power (9) which are poured in on the top.

The process of exothermic welding                                 

Lgnited with a spark gun, the starting powder sets off an exothermic reaction in the weld powder, reducing it to molten copper alloy. This instantaneously melts the retaining disc, and flows down the tap hole, to the weld cavity, where it partially melts the conductors, before cooling to leave a fusion weld of great mechanical and electrical integrity
