Abstract
The inhomogeneous temperature field and large temperature gradient in the laser cladding process form thermal stress and thermal deformation, which lead to residual stress. In this paper, numerical simulations are developed to investigate the temperature and stress distributions of the cladding model as well as the longitudinal residual stress on the specific paths under different scanning modes. The results indicate that most of the stress is concentrated in the cladding layer and its bonding region with the substrate. Furthermore, the longitudinal residual stress is the largest along the scanning path direction.
