Temperature Field Simulation of Laser Heated 1045 Steel Using with Shaped Laser Beam Profiles

Abstract:

In this paper, a three-dimensional dynamic simulation model is established for a laser heating process taking into account heat flow by conduction and a temperature dependent specific heat capacity in the material. An unorthodox laser beam profile is characterized by two simple beam shape parameters in the model; the difference in energy distributions between the centre and outer edge of the beam and between the leading and trailing edges of the beam is varied by an adjustment of these parameters. In this way, laser surface heating with unorthodox beam profiles is simulated and studied using COMSOL Multiphysics finite element modeling software.
