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.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

nVent CADDY 65 – Frequently Asked Questions

1) What connection types does the CADWELD 65 weld metal cover?
The nVent CADDY 65 CADWELD weld metal charge is formulated for two connection types: copper-to-copper (Cu-Cu) and copper-to-steel (Cu-Steel). That covers conductor-to-conductor grounding splices as well as welding copper conductor directly to structural steel members and rebar. One charge model, model 65, handles both.
2) Do I need a power supply or generator to make a CADWELD grounding connection in the field?
No. The weld reaction in the CADDY 65 weld metal is self-contained and exothermic, so no external electrical power source is required. That is what makes it workable on remote grounding grids, substation yards, and tower sites where there is no service to tie into.
3) Is the weld metal charge all I need, or do I have to order a mold too?
The CDY-65 is the weld metal charge only. It is sized for use with compatible CADWELD molds and ignition equipment, so you need the correct mold for your specific conductor size and connection geometry, plus an ignition source, to actually make the weld. The charge is the consumable you reorder; the mold is reusable.
4) Why use an exothermic weld instead of a mechanical or crimped grounding connector?
A mechanical lug or crimp is a pressure joint, and pressure joints can loosen and climb in resistance as they age and corrode. The CADWELD process fuses the metals into one continuous conductor, giving a permanent low-resistance connection that will not loosen, corrode, or increase in resistance over the life of the installation. For buried grounding grids and rebar connections you cannot inspect again, that is the reason specifiers call for exothermic.
5) Can I use CADWELD 65 weld metal to bond a ground conductor to rebar in a concrete-encased electrode?
Yes. The Cu-Steel formulation welds copper conductors directly to steel members, rebar, and structural components, which is exactly the connection used for concrete-encased electrode and structural steel bonding. Match the mold to the rebar size and conductor you are joining.
6) What kind of jobs is CADWELD 65 weld metal normally used on?
Typical uses are substation, telecom, and industrial grounding grids, lightning protection and bonding installations, copper-to-copper grounding conductor splices, and copper-to-steel structural or rebar grounding connections. It is a consumable electricians and contractors keep on hand wherever exothermic grounding welds are specified.
7) What material is the CADWELD 65 weld metal, and will it match my copper grounding conductor?
The product material is copper, so the deposited weld matches copper grounding conductor chemistry rather than introducing a dissimilar metal at the joint. That is why it suits both copper-to-copper splices and the copper side of a copper-to-steel weld.
