EXOTHERMIC WELDING SYSTEMS What is Exothermic Welding?Exothermic welding is the welding process that can be applied easily even for different metals, such as copper-copper, copper-steel, steel-steel, aluminum-copper, aluminum-aluminum in joints that must...Importance of Exothermic Welding in Grounding SystemsOne of the most important problems experienced in grounding installations after many years is the corrosion in underground conductor connections, which brings about problems such as loosening and separation....How Is It Done?Connections are made in six steps by using the reaction of powder copper oxide and aluminum under a high degree of heat. 1. The conductors to be welded together are placed securely in a graphite...Materials UsedGraphite Mold (Crucible): A specifically designed graphite mold is composed of a chamber, a discharge hole, and a weld gap. Thermal reaction occurs in the chamber. The molten copper pours into the weld...
