System Overview
Industry:Wind Power Equipment Manufacturing
Key Results: Covers 4X–10X Models · ±0.08 mm Precision · ≥95% UT Pass Rate · 6 Units/Shift Output
Description
AGR Robotics delivered a robotic welding workstation for Chinese largest wind turbine manufacturer, supporting full-series stators and rotors ranging from 4X to 10X. Powered by CLOOS welding systems, it achieves ±0.08 mm accuracy and integrates TOFD flaw detection with real-time heat input monitoring. The station ensures a ≥95% ultrasonic testing (UT) pass rate and stable production of 4 rotors and 2 stators per shift. The system has been running reliably for over 12 months.

Client Background
AGR’s structural manufacturing subsidiary developed and delivered this system to China’s largest wind turbine OEM, automating stator and rotor welding with ≥95% UT pass rate, high consistency, and strong adaptability for multi-spec heavy components.
Key Customer Requirements
• Compatibility with 4X–10X series stators and rotors
• Stable operation with 5-ton load capacity
• ±0.1 mm repeatability and multi-angle positioning capability
• Single-side welding, double-side forming without back gouging

AGR Solution
To meet the customer’s high-precision and heavy-load production demands, AGR designed a fully automated welding workstation equipped with:
• CLOOS QRH-405 robot on a 3-axis gantry, covering long and complex seams
• Dual-axis L-type positioner for dynamic flipping and accurate seam alignment
• Pulse MIG welding process with copper backing plate for full penetration
• TOFD flaw detection and heat input monitoring for weld quality traceability
• Quick-lock clamping fixtures and an HMI interface for simplified operation and reduced downtime

Project Results
• Fully automated welding process for both stators and rotors
• No back gouging or post-processing required
• Output: 4 rotors + 2 stators per 8-hour shift
• ≥95% UT pass rate maintained consistently
• System running stably for over 12 months with proven reliability
