Problems solved by technology

[0005] The existing laser wire feeding cladding device uses an independent wire feeder to directly transport the wire to the inside of the molten pool through the channel inside the wire nozzle. Since the wire flows out of the wire feeder, it needs to pass through the wire feeding hose and the wire nozzle. Internal channels, due to the internal friction of these channels, the speed at which the wire is output to the inside of the molten pool is inconsistent with the speed set by the wire feeder, which will lead to the following problems: 1) The stability of the wire speed Cannot be effectively monitored, which eventually leads to inability to carry out cladding or effective accumulation of formed parts; 2) open-loop control, unable to guarantee the forming accuracy of parts

Description

technical field [0001] The invention belongs to the technical field of laser cladding, and in particular relates to a laser cladding device. Background technique [0002] Laser cladding (also known as laser cladding or laser cladding) is a new surface modification technology. It forms a metallurgically bonded cladding layer on the surface of the base by adding cladding materials on the surface of the substrate and using a high-energy-density laser beam to fuse it together with the thin layer on the surface of the substrate. [0003] Laser cladding features: the cladding layer has low dilution but strong binding force, and is metallurgically bonded to the substrate, which can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance or electrical properties of the substrate material surface, so as to achieve surface modification or The purpose of repair is to meet the specific performance requirements of the material surface and s...
