Abstract:

The development of a detailed finite difference model of lasermaterial heat transfer is described. The model allows for thermal conduction, surface convection and radiation, variation in thermal properties, latent heat, keyhole formation and has some allowance for convection in the melt pool. It accounts for plasma interference but does not discuss the physical mechanisms involved within a keyhole. Some applications are described. Author
