What is Exothermic Welding?

Exothermic Welding is a permanent welding process that joins copper conductors, galvanized steel, stainless steel, and other conductive materials using a high-temperature chemical reaction. Unlike mechanical clamps or bolted connections, exothermic welding creates a molecular bond with lower electrical resistance, exceptional mechanical strength, and long-term reliability.

These welded connections are widely used in electrical earthing systems, lightning protection systems, substations, power transmission, renewable energy projects, railway electrification, telecom towers, oil & gas facilities, and data centres where dependable electrical continuity is critical.
