Numerical simulation of laser cladding of T-shaped components

Abstract

Abstract:

In order to explore the laser cladding process to minimize the residual stress and deformation of T-shaped components, different process parameters were designed and the results of temperature field, residual stress field and deformation field were calculated under different process parameters in this paper. It was found that the constraint

mode affects the peak value and distribution of residual stress and deformation displacement of components, while

different cladding paths and speeds mainly affect the peak value of residual stress and deformation displacement.

The peak values of residual stress and deformation displacement under free placement constraint mode are 89.4%

and 71.1%, 66.3% and 61.6% lower than those under restraint mode of four-corner fixation and two-side fixation,

respectively. The peak values of residual stress and deformation displacement in reciprocating cladding path process are 26.9% and 6.8% lower than those in unidirectional sequential path process, and the peak values of residual

stress and deformation displacement in cladding speed of 10 mm/s are 11.0% and 4.9%, 35.5% and 34.8% lower

than those in cladding speed of 2.5 mm/s and 5.0 mm/s, respectively. According to the index analysis of reducing

residual stress and deformation, the optimal cladding process is to adopt the process of free placement constraint,

reciprocating cladding path and a higher cladding speed.
