What is exothermic welding?
Exothermic welding is a self-contained method of forming permanent electrical connections. A high-temperature reaction involving copper oxide and aluminium takes place inside a mould, producing molten weld metal that bonds the conductors. Common applications include copper-to-copper and copper-to-steel connections. Other metal combinations require the correct mould and weld material; contact our team to confirm compatibility.
Exothermic Welding – Properties
Exothermic welding provides a permanent electrical bond with low resistance. Connection quality depends on selecting the correct mould and weld material and following the installation procedure. Costs include consumables and replacement moulds. Moisture and outdoor weather conditions can affect installation, so follow the supplied preparation and safety instructions.
