Abstract：Understanding the distribution characteristics and influencing factors of residual stress in laser cladding layers is essential for optimizing cladding processes and improving the reliability and performance of coated components.The research status of residual stress in laser cladding layers is reviewed from two aspects of experimental measurement and numerical simulation.In terms of experimental measurement,the basic principles of drilling method,X-ray diffraction method and neutron diffraction method and their application in the measurement of residual stress in laser cladding layers are described,and the advantages and limitations of these methods are analyzed.In the aspect of numerical simulation,the research progress in numerical simulation of residual stress in laser cladding in recent years is reviewed,and the numerical simulation results of the effects of different laser cladding process parameters on the residual stress of the cladding layers are compared and analyzed.Finally,the paper outlines the future development trend of future laser cladding residual stress measurement technology and numerical simulation research of laser cladding layers.
