According to the developing direction of laser remanufacturing technique with automation, flexibility and intelligence. An integrated high-power flexible laser remanufacturing system for industry application is studied, which is developed by means of the existing interface of the robot, the laser and the design of hardware and software for system integration. Coaxial powder feeding system and temperature vision system are developed to three-dimensional cladding and temperature measurement in laser molten pool. Some samples are built by the flexible laser remanufacturing system. It is showed that the system is efficient.
