DEVICE AND METHOD FOR FABRICATION OF ULTRAHIGH-SPEED LASER CLADDING ADDITIVE

摘要

A device and a method for fabrication of ultrahigh-speed laser cladding additive, the device comprising a laser generator (1), a beam expander (2) and a reflector (4), wherein an emergent light path of the reflector (4) directly faces a cladding nozzle (17), and the cladding nozzle (17) is connected to a powder pool (6) by means of a hose (8) and a pump (7) in sequence; a base body (14) is provided below the cladding nozzle (17), and the base body (14) is located on a rotating platform (13); a main stepping motor (11) is fixedly installed below the rotating platform (13) and fixed to a lifting platform (10); and a laser range finder (20) is provided above the base body (14). According to the device, an ultra-high speed laser cladding technology may also achieve a higher cladding speed on a flat plate by means of rotation, and the speed may reach 100 m/min. Meanwhile, in a laser cladding additive process, an ultrasonic vibration platform (15), an infrared camera (18), a high-speed camera (19), a laser range finder (20) and a radiological flaw detection system (16) are started to carry out real-time detection on the laser cladding process and dynamically adjust technological parameters, thereby achieving the purpose of preparing a defect-free high-performance metal component.
