Abstract

The analytical formulation of laser heating mechanism is useful when exploring the laser machining process. The present study covers the analytical formulation of laser pulse heating process for time exponential decaying and intensity step input pulses. The convergence of both solution is introduced in relation to pulse parameters. The analytical expression for the convergence is omitted due to complex nature of the mathematics involved, however, computational method is attempted to identify the pulse parameter for which both results converge. It is found that the surface temperature profiles obtained for both pulses merge when β approaches to zero.
