In automated laser cladding, a laser beam melts powder particles and a thin layer of the substrate to create a coating that is directly bonded to the substrate. Through a sensor system, the quality and geometry of the clad is measured in real time and using an intelligent controller, the laser power and the cladding speed will be adjusted to achieve the desired quality and geometry in the deposited layers. In this process, a great variety of materials can be deposited on different substrates to form a coating with a thickness of 0.1 to 3 mm. Thicker coatings and bulk 3-D parts can be produced by a successive layering technique using the automated laser cladding process. The high solidification rates and unique processing conditions of this technique allow the production of materials with improved properties compared to that of conventional processes.
