Thin Wall Formed by Multi-Layer Overlapping Laser Cladding Forming

Thin wall was formed by multi-layer overlapping laser cladding. The results showed that the surface of thin wall presents granular. Laser remelting could obviously improve the surface finish of the thin wall because of the melt of small granules. Match between the laser beam and the powder stream is very important and directly affects the forming quality. The microstructure of the thin wall presented obviously and continuously grown dendrite. Individual layers form metallurgic bonding and ensure whole properties of the cladding thin wall.
