Exothermic grounding is a process for permanently joining earthing (grounding) or lightning protection conductors together. Exothermically welded connections are engineered to provide a permanent, molecular bond that will not loosen or corrode. The connections are designed to maintain for the life of the conductor and/or installation. They are a current carrying capacity equal to or greater than that of the conductor and will withstand repeated fault currents without failing during operation. Once completed, installers can clearly ensure quality assurance by visual inspection of the new connection. An exothermic weld can be especially useful for joining dissimilar metals. The process has the advantage in that it requires no external heat source and works by employing a chemical exothermic reaction of a thermite composition to heat the conductors to a point where a low resistance, mechanically sound molecular bond is formed once cooled.
