Modelling of laser pulse heating of metallic substrates reduces the experimental cost and optimizes the laser heating parameters. In the present study, exponentially time-varying laser pulse heating with convective boundary conditions at the surface is considered. The closed-form solution for temperature distribution at the surface is presented. The effects of the heat transfer coefficient ( h∗) and pulse parameter (β∗) on the time corresponding to the maximum surface temperature ( t∗Tmax is significant for h∗≥0.02. Moreover, reducing the pulse parameter lowers t∗Tmax.
