Abstract
The dynamics of weld pool solidification were observed using transparent metal-analog systems. It was shown that the observed weld pool shapes in succinonitrile were in good agreement with theoretical heat transfer calculations. It was found that an increase in welding speed lead to a transition from a steady-state to a nonsteady-state weld pool shape. Phenomena such as epitaxial growth, grain selection process, grain boundary melting, and porosity formation were also observed.
