A Study of Metal Properties Repaired by Laser Deposition

Direct Laser Deposition Technology is an additive manufacturing process which directly manufactures a fully dense metal part from CAD model without intermediate steps. The metal powder is delivered into a molten pool created by the focused beam of a highpower laser beam melting the target material. The resulting deposits can be used to build metal parts in a variety of applications. The repair of damaged metal parts is potential application of Direct Laser Deposition Technology. In this research, the advantages of Direct Laser Deposition Technology over traditional welding repair will be studied with respect to the material properties such as tensile strength
