The invention discloses a laser cladding quality intelligent control system and an intelligent control method thereof. The system includes a robot laser cladding belt automatic tracking module, an image preprocessing module, a defect detection module, a data processing module and a feedback control module. The system and the method achieve accurate and rapid positioning and a high degree of intelligence, construct closed-loop control for a laser cladding process, reduce the influence of human factors on a production process, achieve intelligent control, adjust laser parameters in real time according to a detection result of surface defects of a clad layer, and improve production benefit. By utilization of a deep learning technology to automatically identify surface defects of the laser clad layer, the laser cladding quality intelligent control system with good real-time performance, high reliability, high universality and a high degree of intelligence is constructed.
Description
technical field [0001] The invention relates to a laser cladding quality intelligent control system and an intelligent control method thereof. Background technique [0002] Laser cladding technology is a new material surface modification technology based on high-power lasers. Its specific implementation is as follows: under the action of laser beams, the alloy powder or ceramic powder and the surface of the substrate are rapidly heated and melted. After removal, self-excited cooling metallurgically bonds the substrate surface to form a surface coating with an extremely low dilution rate. Laser cladding technology can significantly improve the wear resistance, corrosion resistance, heat resistance and oxidation resistance of the substrate surface. However, the quality of laser cladding is affected by multiple factors such as laser power, spot shape and size, scanning speed, lap rate, substrate material and cladding layer material, and the stability of cladding tape quality c...
