![]() It can be shown by tests that the electrical conductor will melt before the exothermic weld when subject to high short circuit current. ![]() Typical applications include earthing of sub-stations and power plant, cathodic protection, rail connections, lightning protection, telecommunications, etc…Īn exothermic welding shows a lot of advantages in comparison to mechanical or crimping systems.Īs it is a molecular weld it will not be affected by high current surge. The reaction last a few seconds only and the process requires no external power or heat source, making it completely portable and ideal for field use. 60 welds or more welds if properly cared for. The reaction takes place in a graphite mould, which is machined according to the conductor sizes to be welded and which can be used for approx. ![]() The exothermic welding system uses the high temperature of reaction of powdered copper oxide and aluminium. Exothermic welding is a simple self contained method of making high quality electrical connections for welding copper to copper, copper alloy such as brass, bronze or copper to steel. ![]()
