The shipbuilding industry, known as the "crown of comprehensive industry," features long industrial chains and strong industrial driving power. With the sector moving toward high-end and green development, HGTECH has expanded its capabilities in advanced shipbuilding. From raw material cleaning and hull component cutting to welding of small, medium, and large structures, and from intelligent thin-plate flat-section production lines to key components for green propulsion systems, HGTECH delivers complete laser-based intelligent manufacturing solutions, supporting the integration of green and smart technologies for next-generation vessels.
I. Hull Component Manufacturing – Intelligent Equipment
In shipbuilding, steel plate and profile cutting precision directly affects production timelines and product quality, while welding accounts for 30%–40% of labor hours, influencing both cost and scheduling. Traditional methods often struggle to balance accuracy, speed, and consistency. HGTECH's laser cutting and intelligent welding systems, featuring high precision, non-contact processing, and flexible automation, provide an ideal solution for complex material preparation and high-end ship construction, supporting multi-variety, small-batch, and highly customized production.
1.High-Speed Laser Scribing & Marking System
Combining scribing and marking in one system, this solution is widely applied in shipbuilding, offshore engineering, machinery manufacturing, steel box girders, and structural steel fabrication.
Flexible Integration: Can operate as a standalone system or integrate into existing intelligent manufacturing equipment, adapting to various production environments.
Wide Compatibility: Supports ultra-large QR code marking and extended character sets.
High Accuracy: Ensures efficient marking with clear, durable, and highly scannable QR codes.
2.WALC Series Large-Format Laser Bevel Cutting System
Equipped with proprietary real-time closed-loop control and bevel nesting software, supporting multiple bevel processing modes while reducing operational costs.
Large Scale: Handles plates up to 40 m × 6 m, suitable for ultra-large steel plates.
High Precision: Can form various bevels and angles within 45° in a single pass, minimizing waste and lowering costs.
Modular Design: Segmented box-girder bed reduces material use and saves installation space.
Software Integration: Fully compatible with mainstream ship design tools, including Tribon M3 and Tekla Structures.
3.High-Power Laser Welding System
Integrated with automatic loading/unloading, workpiece clamping, fiber laser welding heads, seam tracking, and weld quality monitoring. This enables continuous, high-quality, and cost-efficient welding.
Stable Quality: Minimizes deformation and maintains consistent weld quality.
Eco-Friendly Manufacturing: Non-contact, pollution-free, and low material consumption processes.
II. Hull Component Manufacturing – Intelligent Production Lines
1.Intelligent Laser Cutting Automatic Production Line
The line comprises specialized systems for component, deck, and profile cutting. The production layout is optimized for smooth logistics, guided by modeling and simulation to design manufacturing routes, material flow, and distribution. This ensures efficient, organized, and streamlined handling of hull components across the production process.
2.Thin Plate Welding Intelligent Production Line
For high-end vessels, thin steel plates (4–12 mm) are used above the waterline to reduce weight and lower the center of gravity. Traditional gas-shielded welding introduces high heat, deformation, and low efficiency. HGTECH's laser hybrid welding, integrated with automated production lines, improves welding efficiency, shortens construction cycles, reduces material and energy consumption, and enhances weld quality.
The Thin Plate Flat Section Welding Line combines high-power laser hybrid welding with visual seam tracking and path correction, minimizing plate deformation. With industrial IoT and centralized intelligent control, the line enables flexible, automated, and high-quality welding.
HGTECH also provides a comprehensive range of laser cutting and welding lines, integrated with digital and intelligent manufacturing technologies, to deliver tailored solutions for shipbuilding projects.
