Exothermic Connections

nVent ERICO Cadweld 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. The nVent ERICO Cadweld connection has 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. With reliable connections that consistently exceeded IEEE® 837 2014 EMF test requirements as certified by an independent lab, nVent ERICO Cadweld is the ultimate welded connection.

Standard Molds
nVent ERICO Cadweld standard graphite molds are designed and engineered for thousands of connection styles.

Heavy Duty Molds
Heavy duty connections use a larger size connection cavity in the mold and a larger size welding material than the equivalent standard duty connection.

nVent ERICO Cadweld Exolon Reduced-Emission Molds
nVent ERICO Cadweld Exolon connections are designed and engineered to virtually eliminate reaction smoke. A unique electronic starting system makes this an ideal solution for sensitive applications.

Cathodic Molds
nVent ERICO Cadweld cathodic protection connections are designed and engineered for pipelines and metal structures requiring corrosion protection. They use a special welding material alloy to minimize heat effect on steel pipes.

High Voltage Molds
Better than mechanical connections and less labor intensive than MIG or TIG welding, nVent ERICO Cadweld high voltage connections are ideal for high voltage applications.

nVent ERICO Cadweld One Shot
The nVent ERICO Cadweld One Shot is a convenient, single-use ceramic mold and welding material connection package designed primarily to connect small conductors to each other or to a ground rod.

nVent ERICO Cadweld Multi
nVent ERICO Cadweld Multi is a multifunctional mold package and universal mold crucible capable of performing a wide range of connections.

Molds and Accessories for Usage on Railway Properties
Introduced in 1939 to simplify the installation of rail bonds, continuous product development and innovation allows nVent ERICO to maintain a global leadership role in exothermically welded connections to the rail and in the track wayside.
