Abstract
A volume of fluid finite difference method based computer code was dev eloped to simulate the heat transfer and squeezing flow in the hot-pla te welding process. The simulation results include melt displacement, temperature distribution, and stress build-up and relaxation. By imple menting the crystallization kinetic model developed in Part I, the for mation of stress-induced crystal structure in the heat affected zone c an be revealed.
