Study on Repair Technology of Profile Parts Based on 3D Scanning and Laser Cladding

In modern industry, components used in the aerospace and defense industries have high requirements and they are mostly expensive and have few spare parts. It is of great economic significance to carry out defect detection and rapid repair.A method of combining 3D scanning with laser cladding was proposed for the study of profile parts repair.Firstly, the defect area point cloud of the profile parts is obtained through 3D scanning, then digital processing is performed to obtain the mathematical model of the defect part, finally an industrial robot combining laser cladding technology is used to repair regional defects.The experimental results show that this method can be used for precise repairing of complex profiles.
