Abstract
The present disclosure relates to a wide laser beam high-throughput additive-manufacturing and cladding device and a working method thereof, and belongs to the field of surface engineering for materials. In the present disclosure, an external optical fiber is connected to an optical fiber interface to input a laser, and the laser passes through a collimating lens, a diffractive optical element (DOE), a concentrating lens, and a protective lens successively, such that a wide laser beam laser beam is output at an outlet of a nozzle, with a beam width of 20 mm to 40 mm. Two powder-feeding tanks are connected to a powder-feeding interface of the nozzle through a powder-feeding pipe. A cooling water pipe is connected with a plurality of water-cooling interfaces to form a circulation. An external shielding gas is connected to a shielding-gas interface to provide a central shielding gas.
