Abstract: In order to effectively reduce the deformation and improve the forming quality, the radial laser cladding process optimisation for annular thin-walled parts with numerical simulation and orthogonal experiment is carried out in this paper. A three-dimensional thermal-mechanical coupling finite element model for laser cladding of the annular thin-walled part is established. Based on the orthogonal experiment, the influence of laser power, scan speed and laser spot radius on the formation quality of radial single-layer cladding layer is investigated. The residual stress result shows that the maximum value of the residual stress in each direction appears at the junction of cladding layer and substrate. The optimal process parameters combination is laser powder of 1,400 W, scan speed of 21 mm/s, laser spot radius of 2.5 mm with smaller deformation and well forming quality. The results can provide some scientific and theoretical guidance for actual laser cladding of annular thin-walled parts.

Keywords: radial laser cladding; thermal-mechanical coupling model; annular thin-walled part; process optimisation.
