Overview

Pneumatic rod butt welder for repeatable joints

A pneumatic rod butt welder joins two rods end to end using resistance heat and air-powered force. The rod ends are clamped in copper jaws, the welding current heats the joint faces to a plastic state, and the pneumatic system pushes the ends together (the upset) to forge a solid joint without filler wire, rod or gas.

Air operation applies the same clamping and upset force on every weld, which is what production lines and wire-drawing plants need when volumes rise or operators change. CRUXWELD builds both pneumatic and lever-operated rod butt welders; the right model depends on your material and rod diameter.

✓Steel bar and rebar joints
✓Bicycle and motorcycle wheel rims
✓Blanks for cutlery and kitchen knives

How a weld is made

1. Clamp. Both rod ends are gripped in copper clamps that also carry the welding current.
2. Heat. Current flows through the joint and resistance heats the faces to a plastic state.
3. Upset. The pneumatic system presses the ends together to forge the joint.
4. Finish. The flash ring is ground off so the rod can be drawn through a die.

Frequently asked questions

What rod sizes can a pneumatic rod butt welder join?

That depends on the model and the material. Send your material and rod diameter on WhatsApp and our technical team will recommend the right machine.

Pneumatic or lever-operated: which is better?

A lever-operated machine such as our CRB-30K leaves the jaws in the operator’s hands. Pneumatic operation applies the same force on every weld, which helps on production lines.

Does the joint need finishing?

Yes. The upset pushes out a small flash ring, which is removed by grinding so the rod can pass through a drawing die.
