Laser cladding technology is an advanced surface modification technology for metal materials, which has been widely used in various industrial fields such as automotive industry, aerospace, petrochemical industry, etc. However, in the actual forming process, due to the differences in thermophysical properties between the fusion cladding material and the base material as well as the existence of a high temperature gradient in the heated zone, which leads to plastic deformation due to high local thermal stress, the subsequent cooling contraction phase generates high residual stress, easily leading to deformation of the part. The work aims to reduce the complex residual stress, deformation and coarse grain size generated during laser cladding of thin plates and improve the quality of the cladding layer and the reliability of part assembly.
