I. Introduction
Blending modern advanced manufacturing technique conception, Laser remanufacturing technology is an advanced laser rapid remanufacturing technology that has been developed based on the repairing platform of laser cladding. With the development of high power lasers, laser cladding is a new surface modification technique that refers to many subjects such as, optics, mechanics, electricity, computer, material, physics, chemistry and so on. Taking metal powder as restorative materials, which is melted by laser, laser cladding melts the matrix material to form a good metallurgic bond layer. Processed by laser cladding and precision machining, the components can build the shape and dimension structure of original parts, resume their performance and use value and complete the final repair and remanufacturing. Laser remanufacturing technology is not only able to resume the original shape and dimension of the damaged parts precisely but also to improve the performance to a large extent , . With the development of the advanced manufacturing technology, automatic and intelligent features are considered into the inexorable trend of the development of Laser remanufacturing technology.
