The integrity and performance of a weld is, to a large extent, controlled by the solidification behavior of the weld metal or fusion zone (FZ). It controls weld-metal microstructure, grain structure, inclusion distribution, porosity, hot-cracking behavior, and, ultimately, weld-meted properties. Weld metal solidification can be understood in the light of recent advances made in solidification theories that relate to castings and rapid solidification of materials. This paper summarizes some of the recent progress made in understanding the weld-pool solidification behavior and its influence on weld-metal microstructures.
