The laser cladding technology, also known in its different standards as LMD or DLD is a useful additive technology for the manufacture and repair of metallic components. 

The powder or wire used as filler material is injected through a nozzle to be melted by the laser, thus generating a coating on the metal substrate.

This overlay welding technique has serveral advantages when compared with other traditional overlay techniques, such as lower thermal input, automation, and better mechanical properties. 

PROPERTIES

• High precision and repeatability
• Minimum heat affected zone.
• Low dilution, driving to a high purity in the coating material. 
• Low component distortion.
• Controlled thickness (0,5 - 1.5 mm / layer). Possiblity to apply multilayer coatings.
• Fine microstructure with high mechanical properties. 
• 100% dense coatings.
• Strong metallurgical bonding between coating and substrate.
