Laser Cladding Rapid Forming is a new developed technology on the basis of laser cladding and rapid forming in the recent years. In LCRF the substrate and the metallic powder fed synchronously are melt by laser beam and the metallurgical combination is formed, then the compact part with regular figures is manufactured layer by layer on the substrate. LCRF has some special advantages, such as high integration, high production efficiency, wide range of processable materials, no pollution to the environment and so on.
