LASER CLADDING

 

Laser cladding, also known as LMD or DLD is an additive technique for repair and manufacturing of metallic components.

The powder used as the filler material is injected through a coaxial nozzle to be melted by the laser, thereby generating a coating on the metallic parent substrate.

For this process, we use a high power laser connected to a robot or CNC system.

In Tecnoclad we have a wide experience in the optimization and development of this process and we can offer you the best solution for your final application.


 

PROPERTIES


  • Minimum heat-affected zone. Controlled and localized heat input.
  • Low dilution, maintaining a high purity in the deposited material without altering its properties.
  • Low part distortion.
  • Thickness controlled coatings (0,5-1,5 mm/layer). High-thickness multilayer coatings are also available.
  • Thin microstructures with high mechanical properties are obtained.
  • Coatings with 100% density.
  • Strong metallurgic bond between coating and substrate.
  • High precision and reproducibility (Automated process).
