WUXI ABK Wind Tower Welding Line Technical Solution

Precision Blanking Process for Conical Tower Sections
Nuestra wind tower production line implements strict dimensional control for conical single-section fabrication, where upper and lower diameter tolerances are critical. The automatic blanking system maintains ±1.5mm precision on main steel plates using laser-guided feeding technology, essential for ensuring subsequent circular seam welding quality. This process is supported by our CNC cutting equipment with real-time thickness compensation.

Flange Welding Deformation Control
To address flange distortion challenges in wind turbine tower manufacturing, we deploy:

1. Segmented symmetrical welding technology with our SAW (Submerged Arc Welding) systems

2. Automatic circular seam straighteners featuring hydraulic pressure up to 300 tons

3. Post-weld heat treatment stations for stress relief

These solutions reduce flange runout to <2mm/m, exceeding EN 1090-2 standards for offshore wind tower fabrication.

Tower Section Assembly Optimization
For long-section towers (12-30m), our production line integrates:

• Laser centering systems with ±0.5mm alignment accuracy

• Digital pre-assembly platforms that boost efficiency by 40%

• Automated clamping fixtures para flange-to-shell matching

The welding positioners y rotators in our line accommodate diameters up to 6m, while adaptive welding tractors ensure consistent girth weld quality throughout the tower section rolling process.

Key Technologies & Equipment
✓ Robotic welding cells for longitudinal seams
✓ 3D scanning systems for dimensional verification
✓ Smart welding parameter database with 100+ preset programs
✓ Turnkey production solutions from blanking to final inspection

Quality Assurance
All systems comply with:
- GL Certification for wind energy components
- ISO 3834-2 welding quality standards
- CE Machinery Directive requirements

Main Components of Wind Tower Welding Line:

1.Bending Machine:

2.Línea de soldadura de torres eólicas CNC Cutting Machine:

There are two kinds of CNC cutters for you to choose: CNC flame cutting machine and CNC plasma cutting machine, and both of them can simultaneously cut several plates, so the cutter is highly efficient.

3. Welding Equipment:

The welding equipment mainly consists of welding manipulator, submerged-arc welding system, automatic recycling feeding system, and welding rotator.

4.Welding Rotator Set:
The matching part and circular seam welding section of the wind tower tube are mainly made up of welding manipulator, submerged arc welding system, automatic recycling feeding system, welding rotator.

5.Sandblasting and Painting
Turning rolls, with walking ability, are fitted to facilitate the sandblasting and painting process of the tower tubes. The painting turning rolls have adopted middle-concave roller wheels, which can be used to support flanges so that painting work can be finished conveniently. The motor is anti-explosive and dust-proof.
