The characteristics of laser cladding and laser remanufacturing technology are introduced. Laser cladding technique is one of the basic techniques of laser remanufacturing technology. It has many characteristics such as high bonding intensity,small heat affect zone,small heat deformation,good automation control etc. The combination of many processing techniques,which mainly consists of laser cladding,and remanufacturing products form Laser remanufacturing technology. It is the important part of remanufacturing technologies. It has characteristics of high quality,high efficiency,economized energy sources,economized material and environment protection. The rise and development of this technology offers a new technical means for the repairing and rebuilding of important mechanism equipments made in China and some importing products. In China,laser remanufacturing technology is widely applied to many industries such as petroleum and chemical,metallurgy,electric power etc. Some representative examples of important mechanism equipments processed by laser remanufacturing are illustrated in this paper. Developing laser remanufacturing of important mechanism equipments has wide market in China. Further more it has important economic and societal benefit.
