Description

technical field [0001] The invention relates to a powder mixing device, in particular to a powder mixing device for laser cladding and a powder mixing and feeding method. Background technique [0002] Laser cladding is a process in which powder materials are melted and added to the molten pool formed after the substrate is irradiated by laser, and the two are rapidly solidified together to form a metallurgical bonding coating by presetting powder or synchronous powder feeding. . Through laser cladding, various complex dense metal parts can be directly manufactured without using tools and molds, and the damaged parts can also be repaired and remanufactured directly on the surface to shorten the development cycle, save costs and reduce energy consumption , Laser cladding has good application prospects in aerospace, weapon manufacturing and mechanical electronics industries. [0003] With the in-depth application of laser cladding technology in biology, aviation, aerospace, m...
