Abstract
In this paper, finite element techniques are used to model laser spot
welding of both metallic and ceramic materials. The materials modelled were
aluminum and alumina, a typical ceramic. In the formulation, the steady state
mass, momentum, and energy conservation equations are considered with surface
tension and buoyancy forces driving the fluid flow. The results indicate that
fluid flow must be considered in order to accurately model molten pool
characteristics for ceramics since the coupling of fluid flow to heat flow is
more important for ceramics than for metals.
