Shipbuilding revolves around four key stages: steel pretreatment, hull component processing, hull assembly and welding, and painting. The required equipment covers six major categories, including hull processing, welding, hoisting, and painting.
Currently, the shipbuilding industry's traditional reliance on manual labor or low-automation equipment faces significant challenges such as low efficiency, insufficient processing precision, high environmental pressure, and persistently high costs. Upgrading core processes like cutting, bending, welding, and surface pretreatment to intelligent equipment can boost shipbuilding efficiency by 30%-40%, reduce operating costs by 18%, and significantly shorten delivery cycles, becoming crucial for shipyards to enhance their core competitiveness.
Industry Challenges
01
Thick Plates & Large Dimensions
Shipbuilding commonly uses high-strength shipbuilding steel with thicknesses ranging from 8 mm to 30 mm or more. Large plate sizes and heavy weights make cutting, handling, and positioning difficult.
02
High Precision Requirements
Hull sections, decks, and bulkheads require tight tolerances for smooth assembly. Cutting inaccuracies lead to misalignment, excessive welding gaps, and costly rework.
03
Intensive Welding Workload
Ship structures involve long, continuous weld seams and multi-pass welding, placing heavy demands on skilled labor and quality consistency.
04
Thermal Distortion & Deformation
Traditional cutting and welding processes generate excessive heat input, causing plate warping and residual stress, which complicate assembly and dimensional control.
05
Tight Delivery Schedules
Shipbuilding projects follow strict timelines. Any inefficiency in cutting, forming, or welding can delay delivery and increase production costs.
06
Environmental pressures
Green capabilities become a core competitive advantage.

Large-Format Laser Cutters
Traditional processing pain points: 1. Low precision of CNC plasma/flame cutting machines (error ±0.5-1mm), requiring secondary grinding; 2. Slow cutting speed, weak adaptability to complex shapes, making it difficult to meet "multi-variety, small-batch" orders; 3. High energy consumption and severe dust pollution.
DN Laser cutting solution: 1. Leading precision: Cutting error ≤ ±0.1mm, beveling in one step, no secondary processing required; 2. Increased efficiency: Cutting speed more than 30% faster than traditional equipment, supporting batch cutting of multi-shape and multi-specification parts; 3. Green and energy-saving: Energy consumption is only 60% of traditional equipment, no dust pollution; 4. Strong adaptability: Can process 4-15mm ship plates, meeting the processing needs of complex structural parts for high-end ships.

Welding Robot
Traditional Welding Processing Pain Points: 1. Low efficiency of manual arc welding/submerged arc welding (welding speed 0.2-0.3m/min), requiring hoisting and flipping; 2. Unstable weld quality, high defect rate (above 0.8%), and large welding deformation; 3. High consumption of welding materials, high labor intensity, and high safety risks associated with high-altitude and confined space operations.
DN Welding Robot Solution: 1. Increased Efficiency: Welding speed reaches 1-2m/min, achieving single-sided welding with double-sided forming, eliminating the need for flipping, increasing overall efficiency by 6 times; 2. Stable Quality: Repeatability accuracy ±0.3mm/m, improved weld strength and toughness, and a defect rate reduced to below 0.2%; 3. Cost Optimization: Welding material consumption reduced by 30%-50%, welding deformation reduced by more than 30%, and lower correction costs; Safety Upgrade: Replaces manual labor in harsh environments, reducing labor intensity and safety risks.
Laser cleaning machine
Traditional Processing Pain Points: 1. Sandblasting or chemical cleaning generates large amounts of dust and waste liquid, failing to meet environmental standards; 2. Manual grinding is inefficient (0.3-0.5 m/min) and easily damages the substrate; 3. Uneven surface cleanliness (around Sa2 level), affecting subsequent welding and painting quality.
DN Rust and Paint Removal Solution: 1. Environmentally Friendly and Pollution-Free: No dust or waste liquid emissions, complying with green manufacturing policies; 2. Highly Efficient and Non-Destructive: Cleaning speed reaches 1-2 m/min, without damaging the sheet material and preventing substrate thinning; 3. Quality Upgrade: Surface cleanliness reaches Sa3 level, enhancing weld joint strength and paint adhesion, reducing the risk of later corrosion; 4. Flexible Adaptability: Can handle complex curved surfaces and confined spaces without disassembling parts.
