Note: A 2‑3 mm gap shall be kept between the flat‑strip and the stranded conductor. Column A in the table refers to international copper stranded conductor specifications for reference only. It is also applicable to other materials such as copper‑clad steel grounding wire, round steel bar, copper‑clad steel grounding round wire, etc. The corresponding mold model can also be changed, for example: mold model CW2#200 for 40×4 flat‑strip and Φ12 round steel bar welding.

Mold Structure

A standard exothermic welding mold typically includes:
Component Description
Mold Body Main graphite structure containing the weld cavity
Mold Cover The top part is used to seal the mold during the reaction
Reaction Chamber The space where welding powder reacts
Weld Cavity Area where molten metal forms the final weld
Flow Channel Guides molten metal into the weld cavity
The mold must be used together with a mold clamp to keep the mold tightly closed during welding.

Key Features

Feature Description
Precision Machining Accurate mold alignment ensures consistent weld quality
Optimized Flow Design Smooth molten metal flow reduces porosity and defects
High Temperature Resistance Withstands the extreme heat generated during the welding reaction
Stable Weld Formation Produces strong and reliable weld joints
Easy Operation Designed for fast and simple field installation

Service Life

Typical mold lifespan:
50 – 200 weld cycles
Actual service life depends on several factors:
Proper welding operation
Adequate cooling time
Regular cleaning and maintenance
Correct handling can significantly extend the lifespan of the mold.

Maintenance & Usage Tips

To ensure stable welding results and extend mold life:
Allow proper cooling
Wait about 15–20 seconds after the reaction before opening the mold.
Clean the mold cavity
Remove residual slag after each weld using a brush or copper wire brush.
Avoid mechanical damage
Handle molds carefully to prevent cracks or deformation.
Keep molds dry
Store molds in dry conditions to maintain structural stability.

FAQ – Exothermic Welding Mold

Q1: What material are exothermic welding molds made of?
Most molds are made from high-density graphite, which provides excellent heat resistance and allows precise shaping of the weld cavity.

Q2: How do I choose the correct mold?
The mold must match:
The type of connection (cable-to-rod, cable-to-cable, cable-to-steel, etc.)
The size of the conductors
The required welding powder amount
Each mold is designed for a specific welding configuration.

Q3: How many times can a mold be used?
A typical mold can be used 50–200 welding cycles, depending on proper usage and maintenance.

Q4: Why do welds sometimes stick to the mold?
This may occur if:
The mold is opened too early
The mold cavity is not cleaned properly
Excess heat accumulates in the mold
Allowing proper cooling time usually solves this issue.

Q5: Do molds need to be replaced frequently?
No. With proper cleaning and cooling procedures, molds can be used for many welding cycles before replacement is necessary.

Q6: Do I need a clamp to use the mold?
Yes. A mold clamp is required to hold the mold firmly closed during the welding reaction to ensure safety and welding quality.
