Wind Energy

Professional Weld Preparation for Wind Tower Manufacturing
High-performance beveling solutions for wind towers, flanges, heavy plate and offshore wind structures.

A Turbine's Lifespan Is Built Into Every Weld

Wind towers operate under continuous cyclic loading for decades. Consitent weld preparation is critical to producing reliable structural joints across large tower sections and heavy plate components.

N.KO beveling machines deliver accurate, repeatable weld-ready edges while reducing manual grinding and improving production efficiency.

Key benefits

Key benefits of beveling machines in wind energy fabrication

Consistent Bevel Geometry

Faster Production

Built for Heavy Plate

Cold Machining - No Heat Input

Ready for Automated Welding

Less Rework

Weld prep in fatigue-driven design

Wind tower sections are fabricated from heavy steel plate and require long, consistent weld preparations across large components.

Consistent weld preparation for demanding structural welding procedures and quality requirements used throughout North American wind tower manufacturing.

These structures are subject to:

  • continuous wind load
  • dynamic stress cycles
  • long-term fatigue



Cold beveling.
No heat-affected zone

Clean, consistent edge preparation without thermal cutting or additional heat input into the material.

What Machined Prep Delivers in Turbine Manufacturing

Consistent results. Section after section.

Machine-controlled beveling delivers repeatable edge preparation across production runs, operators and shifts.

Consistent Preparation for Critical Welds

Accurate, repeatable bevel geometry provides a consistent foundation for high-quality welds in fatigue-sensitive structures.

Less Variation. Less Rework

Consistent edge preparation helps reduce fit-up variation and production corrections before welding.

Accurate Flange Prep

Flanges need an even bevel all the way around, and machining delivers that reliably.

Support for Automated Welding

Consistent bevel prep is essential for stable, efficient automated seam welding, both longitudinal and circumferential.

Repeatable Process Control

Machine-controlled beveling helps manufacturers maintain consistent edge geometry across production runs, supporting documented quality procedures and inspection requirements.

More Beveling.
Less Grinding

Replace labor-intensive manual edge preparation with controlled machining. N.KO automatic-feed bevelers travel along the plate, delivering consistent geometry with less operator effort.

An investment in lifetime performance and project economics

Wind turbines are designed for 20 years or more of continuous operation.

A defect in a welded joint can lead to costly repairs, downtime or reduced structural integrity.

Beveling machines help ensure consistent weld preparation from the start, supporting long-term performance and reducing lifecycle costs.
