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 Equipment is used by some of the world's most demanding customers. JSBOUND is the only manufacturer that can offer exothermic welding, as well as compression and bolted connectors for grounding applicationbs.LEDWELD exothermic welding is a efficient, high-quality metal joining way for connecting metal conductormust use welding powder
During exthermic welding process operation, the reaction chamber and welding cavity temperature reached about 2500 °C and 1200 °C .The material of the mould is graphite. The life of each mold design on average of 50 times, but the correct use and maintenance would extend the mould's life. Previous empirical data, the correct use and maintenance of die life can be extended to 100 times.
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
The process of exothermic welding
Ignited 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.
