The thermal effect of the interaction between laser and metal material is one of the most important physical phenomena when the laser irradiates metal surface.The laser-induced heating leads to the sharp temperature rise of metal surface, which will soon reach material melting point.By using the commercial CFD software FLUENT, this paper examines the interactions between laser and metal materials under different light spot radius and gets metal materials distribution of temperature field along the radial and axial before melting under certain assumptions and boundary conditions and the maximum temperature of flow and the location, and how oxidation reaction and convection heat transfer influence thermal effects is also observed.
