Abstract

The present invention relates to an apparatus and method for additive manufacturing by ultra-high-speed laser cladding. The apparatus includes a laser generator, a beam expander, and a reflector. A light exit path of the reflector is arranged facing a cladding nozzle. The cladding nozzle is connected to a powder pool through a hose and a pump in succession. A matrix is arranged below the cladding nozzle. The matrix is located on a rotary platform. A main stepping motor is fixedly mounted below the rotary platform. The main stepping motor is fixed on a lifting platform. A laser rangefinder is arranged above the matrix. During the laser cladding-based additive manufacturing process, the ultrasonic vibration device, the infrared camera, the high-speed camera, the laser rangefinder, and the radiological inspection system are turned on to monitor the laser cladding process in real time.
