In the current global competitive landscape of shipbuilding, European shipyards are facing severe labor challenges. Traditional welding work is physically demanding with harsh labor conditions, leading to a significant loss of highly skilled welding talent. To maintain manufacturing quality and meet increasing safety standards, the transition from manual operations to intelligent robotic welding stations has become industry consensus.

• Difficulty in Maintaining Consistency: Manual welding is highly susceptible to human factors, leading to welding stress and deformation that result in high correction costs.
• Environmental and Health Risks: Welding fumes and high-temperature environments deteriorate labor conditions, making it difficult to attract young technicians.
• Challenges with Modern Materials: As high-strength low-alloy steels and corrosion-resistant steels are adopted, manual methods struggle to meet precise parameter control requirements.

Modern intelligent stations integrate various high-efficiency welding technologies to achieve precise coverage of different plate thicknesses in shipbuilding.

Automated stations perform parametric matching based on ship component specifications:

• Thin Plate Welding (4-12mm) is used primarily for superstructures and bulkheads, using laser welding or hybrid methods to reduce heat input and control deformation.
• Thick Plate Welding (12-50mm) is applied to hull bottoms and side shells, utilizing submerged arc or hybrid welding to achieve deep penetration and ensure structural integrity.

The core of intelligent transformation lies in converting "empirical judgment" into "data analysis." Integrated sensors, cameras, and computer systems allow the stations to:

• Real-time Acquisition: Capture weld morphology, temperature, and electrical parameters at millisecond intervals.
• Dynamic Adjustment: Provide real-time feedback based on operating conditions to ensure process repeatability and enhance production efficiency.

For European shipyards seeking transformation, the construction of automated stations should focus on three dimensions:

• Integration: It is not just about adding robots, but synergizing laser, arc, or friction stir welding methods. For instance, using Friction Welding for dissimilar materials achieves high-quality solid-phase connections without porosity or oxidation.
• Traceability: Establish a comprehensive weld evaluation system to ensure every seam's data is searchable and manageable, meeting strict international classification standards like DNV.
• Sustainability: Prioritize low-energy, low-emission processes (such as Electron Beam or Friction Welding), which comply with European environmental regulations and improve the workshop environment.
