Exothermic Welding Molds for Cable-to-Rebar Connections are purpose-built graphite molds for joining stranded copper cable to reinforcing steel (rebar) with a permanent molecular bond.

Unlike mechanical clamps or bolted rebar connectors, an exothermic cable-to-rebar weld creates a low-resistance, corrosion-resistant connection that does not loosen under concrete pour, thermal cycling, or fault current.

If you are sourcing exothermic welding molds Cable-to-Rebar CRE1, CRE2, CRE3, CRE6, CRE17, this category covers the standard connection styles.

Cable-to-Rebar Connections

This range focuses on commonly requested Cable-to-Rebar mold codes:

• CRE1 / CRE2 — compact cable-to-rebar joints for lighter conductors and smaller rebar diameters
• CRE3 / CRE6 — mid-range connections for standard copper cable and rebar sizes in foundation grounding
• CRE17 — heavier cable and larger rebar sections where weld volume and mold cavity size must match higher-capacity conductors

Exact mold selection depends on cable cross-section, rebar diameter, and joint type. Share your conductor dimensions and connection sketch, and we will confirm the correct CRE mold, welding powder charge, and handle/frame accessories.

Applications

CRE cable-to-rebar molds are widely specified for:

• Foundation and pile-cap grounding cable-to-rebar bonds
• Structural steel and concrete equipotential bonding
• Lightning protection connections into reinforced concrete
• Industrial and building grounding where mechanical rebar clamps are not preferred

Because the finished weld is permanent, these molds are preferred on projects that prioritize long-term electrical continuity and reduced maintenance.

Choose

To choose among CRE1, CRE2, CRE3, CRE6, and CRE17, confirm:

1. Conductor size — cable mm² (or AWG) and rebar diameter
2. Joint orientation — tee, side-tap, or parallel cable-to-rebar layout
3. Powder size — matched weld metal volume for a complete fill

Using the wrong cavity size is the most common cause of incomplete welds. If your cable or rebar size sits between two codes, request a size chart before ordering.
