Abstract

Temperature profiles and fluid flow fields in a weld pool are simulated through numerical solutions of Navier-Stokes equation and the equation of conservation of energy for low power laser welding in conduction mode. Experimentally determined weld pool surface topography, peak temperature, and the secondary dendrite arm spacings are found to be in fair agreement with the corresponding theoretically calculated values.
