Wind Tower Welding Line

Core characteristics

• Efficient cantilever workstation
• Modular cantilever structure design, supporting multi-station combination
• Multi-layer and multi-pass continuous welding can be realized, and the efficiency is improved by more than 50%.

• Full-process integrated system
• Comprises a plate bending machine, a numerical control cutting machine, welding equipment, a welding displacement unit and a sand blasting and painting rotary roller.
• All units cooperate to realize the complete processing of tower from plate to finished product.

• EIntelligent welding control
• Digitally adjust welding parameters to ensure the consistency of girth welding.
• Adapt to towers with different diameters (2.5m-6m).

Typical configuration

• Pretreatment unit: CNC cutting and blanking
• Forming unit:three-roll plate bending machine
• Welding unit:cantilever submerged arc welding system (including dust removal device)
• Post-processing unit: sandblasting and derusting+automatic painting turntable

Industrial application

It is suitable for mass manufacturing of 2MW-8MW onshore/offshore wind turbine towers, and is compatible with carbon steel/high strength steel materials.

Key Points in Wind Tower Production:
1.Blanking control of conical single-section tower

• Because the diameters of the upper and lower ends are similar, it is necessary to implement strict tolerance control on the feeding of the main steel plate (recommended ±1.5mm).

2.Welding deformation control of flange

• Adopt subsection symmetrical welding technology
• Matching use of automatic circular seam straightening equipment

3.Optimization of circumferential joint assembly of tower section

• Long-section tower (12-30m) shall be equipped with laser centering system.
• Through digital pre-assembly, the efficiency of assembly is improved by more than 40%

Main Components of Wind Tower Welding Line:

1.Bending Machine:

2.Wind Tower Welding Line 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.
