Abstract

In many practical applications there is a need for a fast and easy estimation of the depth of the laser-melted zone during laser-surface treatment. Closed-form solutions using the Fourier differential equation are quite difficult for problems with phase change and can be impossible for particular boundary and initial conditions. In this paper, we formulate the conservation of energy equation in an integral form and by prescribing the function for the thermal field we are able to derive a simple analytical solution for the evaluation of the depth of the laser-melted zone. The calculated values obtained by the model are in good agreement with the experimental data.
