In heavy industries such as shipbuilding, mining equipment, offshore engineering, and structural steel fabrication, bevel cutting is far more than a simple edge preparation process. The quality of every bevel directly influences weld penetration, structural integrity, assembly accuracy, and ultimately the service life of the finished product.

As manufacturers pursue higher productivity while maintaining strict quality standards, conventional beveling methods are becoming increasingly difficult to justify. Multiple setups, manual alignment, thermal distortion, and excessive material waste often increase production costs and extend manufacturing cycles.

To address these challenges, Han’s Laser has developed a large-format linear-guide laser cutting solution with vision-guided secondary beveling, integrating straight cutting, automatic vision positioning, and precision bevel cutting into a single workflow. The result is a highly efficient process that improves machining accuracy, reduces material waste, and simplifies production for heavy fabrication.

Why Secondary Beveling Matters

Many heavy structural components—including ship decks, stiffeners, side shell plates, hydraulic supports, and large equipment frames—are first cut from medium or thick carbon steel plates before bevels are prepared for welding.

Traditionally, bevels are produced directly on full plates or through separate processing operations. These approaches often introduce several manufacturing challenges:

• Material waste caused by full-plate bevel cutting
• Thermal distortion that affects dimensional accuracy
• Additional manual layout and repositioning
• Multiple handling operations between cutting and beveling
• Longer production cycles and higher labor costs

Secondary beveling changes this workflow. Instead of beveling the entire plate before part separation, finished components are first cut to shape and then precisely repositioned for bevel machining. This approach maximizes material utilization while maintaining high dimensional accuracy.

Large-Format Cutting for Oversized Components

The process begins with Han’s Laser’s large-format linear-guide laser cutting machine.

Designed for heavy industrial applications, the system supports working areas exceeding 110 meters in length and 7 meters in width, allowing oversized components to be processed in a single setup without sectioning or secondary assembly.

Its high-rigidity welded base, aluminum beam, and precision linear guide transmission system ensure smooth motion and stable accuracy across extremely long travel distances.

Because the machine accommodates carbon steel plates of various thicknesses without extensive setup changes, manufacturers can efficiently process diverse production schedules while providing clean, burr-free edges that form the ideal foundation for subsequent bevel cutting.

Dual-Vision Technology for Automatic Positioning

Once straight cutting is completed, the secondary beveling process begins with a dual-vision positioning system.

A coarse-positioning contour scanner first identifies the general location of each workpiece. A second high-precision contour scanner then follows the cut edge, capturing the component’s exact profile, orientation, and position with positioning accuracy within 0.5 mm.

The collected data is automatically transferred to Han’s Laser’s proprietary CAM software, which generates optimized bevel cutting paths based on material thickness, part geometry, and processing requirements.

Because positioning and programming are fully automated, manual marking, measuring, and alignment are eliminated, reducing preparation time while minimizing operator error.

High-Precision Secondary Bevel Cutting

After positioning, the machine performs bevel cutting using Han’s Laser’s dual-axis A/B swing bevel mechanism.

The laser Cutting machine supports bevel angles from 0° to ±45° and can produce multiple weld preparations in a single operation, including:

• V bevels
• Y bevels
• A bevels
• K bevels

Unlike conventional plasma or flame bevel cutting, the laser-based process produces smooth, uniform bevel surfaces with excellent dimensional consistency.

More importantly, bevels are applied only where required after individual parts have been separated, significantly reducing material waste compared with beveling entire plates.

Because laser processing introduces substantially less thermal input than conventional thermal cutting methods, workpieces maintain excellent dimensional stability without the deformation often associated with flame or plasma processing.

According to production data, this approach can improve finished-part yield by as much as 50%, while delivering highly consistent bevel angles and root faces that simplify downstream welding.

A More Efficient Workflow for Heavy Manufacturing

By combining straight cutting, automatic vision recognition, and secondary beveling into one integrated process, manufacturers can eliminate numerous manual operations traditionally required before welding.

Key benefits include:

• Improved material utilization
• Reduced setup and handling time
• Higher dimensional accuracy
• Consistent weld preparation quality
• Lower labor requirements
• Faster production throughput

The streamlined workflow is especially valuable for manufacturers producing multiple part types, complex geometries, or medium-volume production batches where flexibility is essential.

Proven Performance in Shipbuilding and Heavy Equipment Manufacturing

Han’s Laser’s large-format bevel cutting technology has already been deployed across a range of heavy manufacturing applications.

In the shipbuilding industry, the company’s bevel laser cutting systems are used to manufacture decks, stiffeners, and hull structures requiring precise weld preparation for large assemblies.

In mining equipment production, high-power laser systems process hydraulic supports, structural housings, and other heavy components where consistent bevel geometry directly contributes to welding quality and structural reliability.

These real-world applications demonstrate how integrated laser cutting and secondary beveling can improve both manufacturing efficiency and finished product quality.

Driving Smarter Heavy Plate Fabrication

As shipbuilding, mining machinery, and other heavy industries continue modernizing their production systems, manufacturers are placing greater emphasis on process integration, automation, and material efficiency.

Han’s Laser’s large-format vision-guided secondary bevel cutting solution addresses many of the long-standing challenges associated with conventional bevel preparation. By combining oversized processing capability, automated vision alignment, and precision multi-axis bevel cutting, it delivers a practical, high-efficiency solution for today’s demanding heavy fabrication environments.
