Exothermic welding provides higher mechanical strength than other types of welding and offers excellent corrosion resistance. At the same time, exothermic welding ensures a very low contact resistance that remains stable over time. These properties make exothermic welding the best solution for joining copper conductors in an earthing system.
In exothermic welding, very high heat is generated through a chemical reaction, which melts the metals together to create the strongest and most reliable connection. The process is also known as thermite welding.
