Abstract

Laser metal deposition process is an advanced manufacturing process that can be used to fabricate three dimensional (3D) parts from the 3D computer aided design (CAD) model of such parts by adding materials in layers. The CAD digital data of the part is used to generate a motion controlled computer program that is used to control the movement of a laser which then trace all profile of the CAD by injecting the material into the laser focal region of the laser, melted and solidify to form a fully dense track through a moving molten pool that is created by the laser. Tracks and layers are stacked in order to produce the entire component of fused metal that represents the desired 3D CAD object. An important characteristics of this manufacturing process apart from creating a 3D object is its ability to repair high valued parts. Aerospace industry in particular has benefited greatly from this important technology. In this chapter, the detailed process description with the various steps involved in the manufacturing process are explained. The solidification process in the laser metal deposition process with the mechanism of microstructural evolution during this process that give materials processed using this technology, unique properties are also explained in detail.
