Abstract

The invention discloses a multi-sensor synergistic monitoring apparatus and method for broadband laser cladding. The apparatus comprises a displacement sensing unit, an image sensing unit and an information processing unit; a coaxial powder feeding head is provided with four sensor connection arms in central symmetry, and the end part of each sensor connection arm is respectively provided with the image sensing unit or the displacement sensing unit; and the two image sensing units are distributed around the coaxial powder feeding head at a given adjustable angle and used for acquiring an appearance image of two baths in different directions in the broadband laser cladding process. The information processing unit is used for melting and processing height data acquired by the displacement sensing unit and the bath images acquired by the image sensing unit, calculating and displaying an area as well as a three-dimensional size, height of a forming layer, a defocusing amount and a lap joint rate of a broadband rectangular bath in real time. By adopting the multi-sensor synergistic monitoring apparatus and method, the broadband laser cladding process can be precisely and comprehensively monitored in real time.

Description

technical field [0001] The invention relates to the technical field of surface engineering, in particular to a multi-sensor cooperative monitoring device and method for broadband laser cladding. Background technique [0002] Laser cladding technology is a material surface modification process that uses a high-energy laser beam to radiate and melt a thin layer of powder material and substrate surface and solidify rapidly, so that the substrate surface and powder material achieve a metallurgical combination. The laser only melts the surface of the substrate, the heat-affected zone is small, the dilution rate of the powder coating is low, and the substrate and the powder material are metallurgically bonded; it can effectively improve the hardness, wear resistance, corrosion resistance and oxidation resistance of the substrate surface, and is currently widely used Remanufacture and repair of key components in aerospace, petrochemical, automobile manufacturing and other fields. ...
