Laser Cladding by Navalis Group: Restoring Shipbuilding Components

In today’s industrial world, where efficiency and durability of equipment play a crucial role, technologies continue to evolve, offering new solutions for process optimization. One such innovation is laser cladding—an advanced technology that is increasingly being used in shipbuilding.

Laser cladding is a process where a high-energy laser beam is used to fuse powdered material onto a component’s surface. Under the laser’s effect, the powder melts and forms a strong metallurgical bond with the base material. This method not only restores worn or damaged components but also enhances their properties, improving wear resistance, corrosion resistance, and other characteristics.

Advantages of Laser Cladding:

  • On-Site Repair: We can perform work directly at the customer’s location, significantly saving resources and reducing transportation costs.
  • High Precision: The laser beam ensures accurate material application, enabling the creation of complex geometries and cladding in hard-to-reach areas.
  • Minimal Thermal Impact: The laser’s concentrated heat minimizes the heat-affected zone, reducing the risk of component deformation and cracking.
  • Wide Range of Materials: Laser cladding supports various materials, including high-alloy steels, nickel-based alloys, cobalt alloys, and more, offering broad application possibilities.
  • High Efficiency: The automated laser cladding process ensures high productivity and reduces equipment downtime.
  • Eco-Friendly: Laser cladding is an environmentally friendly process that produces no harmful emissions or waste.

Engines and Power Equipment:

  • Cylinder Walls: Wear of cylinder walls is a common issue. Laser cladding restores their surface, bringing them back to their original dimensions and geometry.
  • Pistons: The technology is used to restore worn piston ring grooves, piston surfaces, and apply heat-resistant coatings.
  • Valves: Wear and damage to valves can reduce engine efficiency and increase fuel consumption. Laser cladding restores valve surfaces, eliminating cracks and defects.
  • Turbine Blades: Worn and damaged turbine blades are effectively restored, improving efficiency and extending their lifespan.
  • Shafts: Wear on shaft journals, bearing seats, and sealing surfaces is common. Laser cladding restores these parts with high precision.

Transmission and Propulsion Systems:

  • Propellers: Laser cladding is an effective way to restore worn propeller blades, repair cavitation damage, and enhance efficiency.
  • Controllable Pitch Propellers (CPPs): The technology restores heavily worn CPP blades and mechanisms.
  • Gearboxes: Laser cladding is used to repair gears, shafts, and other gearbox components.

Hull and Deck Equipment:

  • Hull Structures: The process is applied to repair ship hull damage caused by corrosion, impacts, or other factors.
  • Deck Mechanisms: Laser cladding restores anchor winches, windlasses, cranes, and other deck equipment.

These are just some of the ship components that can be restored using laser cladding. Its high precision, minimal thermal impact, material versatility, and eco-friendliness make it a universal and effective method for ship equipment repair and restoration.

Conclusion:

Laser cladding performed by Navalis Group is an advanced technology that efficiently restores and enhances equipment components, improving their durability and reliability. Thanks to its numerous advantages, laser cladding is finding increasing applications across various industries, helping boost production efficiency and reduce costs.
