The results shown here are some preliminary studies in the co-operative development of a 3D finite difference model of the laser heating process. Two models are currently under investigation that derived at Imperial College and that at the University of Illinois. They have a similar root in the original work of Mazumder and Steen (1).

Reported here are some results of the working of the model. These illustrate amongst other things the flexibility of this form of calculation and our ability to discuss the importance of latent heat, variable reflectivity, variable thermal properties and keyholing.
