Exothermic Welding Series
Permanent Molecular-Level Connections
Achieve molecular-level connections through exothermic reaction, providing permanent electrical continuity that never loosens or corrodes. The ideal solution for grounding system conductor connections.
Product Introduction
Learn about the core technology advantages of Exothermic Welding Series
Exothermic welding is a process that uses the high temperature (over 2500°C) generated by the chemical reaction between metal oxides and reducing agents to melt and fuse conductors together. This creates a molecular-level bond that is permanent and has the same conductivity as the original conductor.
Unlike mechanical connections that can loosen over time or crimp connections that may corrode, exothermic welding creates a fusion bond that will never loosen, corrode, or increase in resistance. The welded joint can withstand repeated fault currents and has a service life equal to that of the conductor itself.
Our exothermic welding series includes a complete range of molds, welding powders, and ignition systems suitable for various connection types including wire-to-wire, wire-to-rod, wire-to-flat, and flat-to-flat connections. All products comply with IEC 62561, UL 467, and IEEE 80 standards.
