Laser metal deposition
– an ideal process for repair of expensive parts
A thin layer of the base material is melted by the laser heat source in a controlled way. This ensures that a metallurgical bond is created between the coating and the base material. The deposit material can be transferred to the substrate by injecting powder or by feeding a wire.
Laser metal deposition is used to produce and repair high-value parts and components. The process generates high-quality claddings and coatings with a lifetime of parts that partially extends the durability of galvanic coatings. The laser metal deposition process is used for applications in the offshore, oil and gas, aerospace, power generation, automotive and utilities industries.
Using laser metal deposition for repair has several benefits. Highly complex parts can be repaired with automated methods, and because of the low heat input, the heat-affected zone is kept small and thus the strength of the material is preserved intact.
