Numerical Simulation of Laser Cladding Process for Steel 45 Based on Computer Technique
A finite element model of three layers laser cladding process with the size of 30 mm × 20 mm × 4 mm was created, and the temperature and stress field of laser cladding process were simulated successfully. The results show that the node temperature gradually increases with the increase of cladding layer numbers, and the maximum residual stress is near the junction of the cladding layer and the base metal. Deformation is small after the end of the laser cladding. And this has provided a theoretical basis for the optimization of the laser cladding process parameters.
