Abstract

The invention discloses a method and device for manufacturing efficient and high-precision composite additive, and the method and device are achieved through composition of a laser beam and an electron beam. In the process of the action of a high energy beam and metal powder, metal powder of a surface outline is scanned and molten through the laser beam, and the surface of a part has a good surface quality. The electron beam melts the internal powder at a high speed to form a part inner cavity so as to reach the highest forming efficiency. The lower portion of the device comprises a powder laying roller, a workbench, a powder conveying cylinder and a working cylinder. The upper portion of the device comprises an electron beam generating device, a laser beam generating device, a bottom plate, two guide rails, two beams, a synchronous belt wheel and a servo motor. The electron beam generating device and the laser beam generating device are respectively integral and move to the forming area alternately to carry out scanning. By means of the method and device, the defects in the single forming technology can be overcome, and the purposes of reasonably controlling the formed microstructural organization and optimizing the comprehensive performance are achieved.
