Laser technology has become a core process in ship manufacturing, covering cutting, welding, marking, and surface treatment across the entire production workflow. It meets the industry’s strict requirements for precision, reliability, traceability, and efficiency.

1. Laser Cutting (Core Nesting Process)

• Hull plate cutting: High-precision cutting of 6–50mm carbon/high-strength marine steel on large-format sheets (up to 12m+), used for hull plating, decks, bulkheads, and frames, with ±1mm accuracy meeting classification society standards.

• Integrated bevel cutting: One-step forming of 45°–55° welding bevels with slag-free, distortion-free edges, ready for direct welding and eliminating secondary grinding.

• Pipe & profile cutting: 3D cutting for ship piping, stiffeners, angles, and channels, adapting to complex hull structures and reducing on-site modifications.

2. Laser Welding (High-Strength Structural Joining)

• Hull section welding: Joining high-strength steel/stainless steel plates for bulkheads and hull sections, with minimal heat-affected zone and low distortion to enhance structural stability and reduce straightening costs.

• T-Beam welding: As the core structural component of the ship hull frame (such as deck longitudinal bones and bulkhead stiffeners), laser welding can realize efficient butt joint between T-beam flange and web, with uniform weld formation, high strength and small thermal deformation. It does not require complex tooling fixation, greatly improving the processing efficiency and structural reliability of T-beam, and adapting to the lightweight and high-strength design requirements of ships.

• Precision component welding: Seam welding for ship piping systems, valves, hydraulic components, and deck machinery housings, with zero porosity/cracks for high reliability at sea.

3. Laser Marking (Full-Lifecycle Traceability)

• Hull plate marking: Direct printing of ship numbers, batch codes, QR codes, and classification society marks at 25m/min with ±1mm accuracy, enabling full traceability from cutting to assembly.

• Component marking: Wear/corrosion-resistant part numbers and quality data on pipes, flanges, and pumps, ideal for high-salt marine environments, replacing stamps and stickers.

• Construction guidance marking: Direct printing of assembly lines, weld positions, and hole layouts on plates, eliminating manual scribing, reducing errors, and improving welding/assembly efficiency.

4. Laser Cleaning & Surface Treatment (Eco-Friendly Processes)

• Pre-weld preparation: Removal of rust, scale, and oil to improve weld quality, replacing pickling and grinding with a clean, pollution-free process.

• Post-weld/derusting treatment: Fast removal of weld spatter, oxides, and old paint to enhance coating adhesion and extend hull anti-corrosion life.

Key Benefits

• High precision: ±1mm accuracy meets classification society standards, minimizing rework and on-site modifications.

• High efficiency: High-speed cutting, one-step bevel forming and efficient T-beam welding reduce lead times by 30%+, aligning with long-cycle shipbuilding schedules.

• Cost-effective: Nesting improves material utilization; no molds and less labor cut unit costs by 20%+.

• Full traceability: Permanent laser marking supports full-process quality control, meeting strict shipbuilding QA and audit requirements.
