nVent CADDY 65 CADWELD Weld Metal, Copper-to-Copper & Copper-to-Steel

nVent CADDY 65 CADWELD Weld Metal, Copper-to-Copper & Copper-to-Steel

The nVent CADDY 65 CADWELD Weld Metal is the exothermic welding charge used with the CADWELD molecular bonding process to permanently join electrical conductors. This CDY-65 charge is formulated for two connection types: copper-to-copper (Cu-Cu) and copper-to-steel (Cu-Steel), covering both conductor-to-conductor splices and conductor-to-structural-steel grounding welds. Rather than relying on a mechanical or crimped connector, the CADWELD process fuses the metals into a single continuous conductor, producing a permanent, low-resistance electrical connection that will not loosen or degrade at the joint over time. It is a core consumable for electricians and contractors performing exothermic grounding and bonding welds with the nVent CADDY CADWELD system.

Key Features

• Copper-to-Copper (Cu-Cu) Welding: Formulated to permanently weld copper conductor to copper conductor for grounding and bonding splices.
• Copper-to-Steel (Cu-Steel) Welding: Also formulated to weld copper conductors directly to steel members, rebar, and structural components.
• Exothermic Molecular Bond: Uses the CADWELD exothermic welding reaction to fuse conductors into one continuous connection rather than a mechanical joint.
• No External Power Source Required: The weld reaction is self-contained, allowing field installation without an electrical power supply.
• Corrosion-Resistant Connection: The fused molecular joint will not loosen, corrode, or increase in resistance, maintaining a stable connection for the life of the installation.
• CDY-65 Weld Metal Charge: Model 65 weld metal charge sized for use with compatible CADWELD molds and ignition equipment.
