Professional Weld Preparation for Shipbuilding & Marine Fabrication
High-performance beeling solutions for hull plates, structural components, offshore fabrication, ship repair and refit.

A Vessel's Reliability Is Set Long Before It Leaves the Dock

Shipbuilding demands accurate, repeatable weld preparation across long plate edges, heavy structural components and complex assemblies.
N.KO beveling machines produce consistent, weld-ready edges while reducing manual grinding and thermal cutting - helping shipyards increase productivity, improve weld consistency and reduce rework.

Key benefits

Why Shipbuilders Choose N.KO

Consistent Bevel Geometry

Faster Weld Preparation

Less rework

Supports Classification Requirements (ABS, DNV, Lloyd's Register and Bureau Veritas)

Shop, shipyard or field ready

Build for Heavy Fabrication

Weld preparation as a competitive advantage

Shipbuilding operates under strict oversight from classification societies such as ABS, DNV, Lloyd’s Register or Bureau Veritas.

These organizations require:

  • shorter production times
  • higher repeatability
  • fewer defects
  • easier compliance with standards

At the same time, shipyards work with a wide range of materials — from structural steels to high-strength and corrosion-resistant alloys — and across a broad range of thicknesses.

Manual preparation struggles to deliver consistent results in this environment.

Machined beveling ensures precision, repeatability and compliance across all applications.

What Machined Prep Delivers in Shipbuilding

Fewer costly repairs in complex structures

A lot of welding happens deep inside part-built hull sections where access is tight and repairs run expensive. Precise bevel prep raises the odds of getting it right the first time.

Consistency Over Big Surfaces and Long Seams

Machined beveling keeps the geometry even along the full edge, so welding conditions stay stable.

A Faster, More Predictable Flow

Machined prep is quicker and steadier than hand grinding, which smooths out modular construction.

Support for Automated Weld Lines

Panel lines and automated cells need consistent joint geometry, and machined beveling delivers it.

Flexible for Repair, Maintenance, and Refit

Portable bevelers let crews prep edges on-site during repairs or refits — in dock or afloat — cutting downtime.

Dependable Class Supports

Machined beveling is a documentable, repeatable process that backs up inspections and class approvals.

Cold beveling.
No heat-affected zone

Machine clean, consistent bevels without thermal cutting and without introducing heat into the material.

Where n.ko machines are used

Used Across the Marine Supply Chain

They all operate under the same conditions: strict certification, complex structures and high cost of failure.

An investment that supports delivery, certification and uptime

In shipbuilding, delays and rework have a direct impact on delivery schedules and project costs.

A rejected weld or failed inspection can disrupt entire sections of production.

Beveling machines help ensure consistent weld preparation from the start, reducing rework, supporting certification and keeping projects on schedule.
