In welding processes, solidification is very specific. This phenomenon leads to high grain growth rates, in presence of high temperature gradients and strong fluid flows in the liquid, that can change the solidification mechanisms.This work investigates the coupling between fluid flows and solidification mechanisms, related to welding parameters, at weld pool scale (macroscale) and at grains scale (microscale).An experimental study is carried out, based on in-situ observations of a fully penetrated weld pool, generated on a thin Cu30Ni plate with a GTAW torch in two configurations :a static configuration generating an antisymmetric weld pool and a translating configuration generating a weld bead.For each configuration, the solidification mo...
