Exothermic Discs

Shop exothermic discs for use with compatible exothermic welding molds and weld-metal charges. Also called reaction discs, retaining discs or exothermic welding disks, these components are positioned inside the mold crucible to hold the weld metal in place before ignition.

Exothermic reaction discs are a small but essential part of the mold-based grounding connection process. The disc separates the weld-metal charge from the mold cavity until the reaction begins, helping installers prepare conductor-to-conductor, conductor-to-ground-rod and conductor-to-steel connections.

Exothermic grounding materials are used in telecommunications sites, data centers, utilities, electrical substations, commercial facilities and industrial grounding systems. Discs are selected to work with compatible mold and weld-metal configurations used for the required grounding or bonding connection.
