1. Fully Automatic Integrated Welding: Automatic main bar feeding, positioning, and spiral welding ensure unmanned operation with stable CO₂ shielded welding quality.
2. High Efficiency & Labor Saving: A 9–12 m cage can be completed in 20–25 minutes with only 1–2 operators, significantly increasing output per shift.
3. Wide Range & Precision Control: Supports Ø800–2500 mm cages without mold change, with CNC adjustment and ±2 mm pitch accuracy for consistent, reliable production.
CNC Steel Cage Welding Workstation (Model: YGTZ2500-12)
The CNC Steel Cage Welding Workstation YGTZ2500-12 is a fully automatic steel cage forming and welding system with independent intellectual property rights. It is widely used in metro construction, bridges, building foundations, airports, highways, and other infrastructure projects.
The system integrates:
Automatic main bar feeding system
Main bar detection, positioning & welding system
Spiral bar welding system
Automatic cage discharge system
The entire welding process is fully automated without manual intervention.
Main bar welding time is less than 35 seconds per bar. Welding parameters can be preset and stored according to process requirements, significantly reducing labor while greatly improving efficiency.
A 9–12 meter cage framework can typically be completed in about 20 minutes, and spiral winding and welding can be finished within 25 minutes.
The system ensures:
No false welding
Stable and reliable weld quality
Precise control of welding time and position
Reduced welding material consumption
Multiple cage specifications can be preset and stored. Operators simply select parameters via touchscreen for one-button production. The production flow is streamlined and highly automated.
Compared to manual fabrication that requires frequent on-site supervision, this workstation automatically monitors and records welding data in real time, generating inspection reports and ensuring stable, compliant production quality.
