Wire-Arc Additive Manufacturing (WAAM) is highly efficient, can achieve high deposition rates and does not rely on expensive equipment.WAAM thus has the potential to produce large scale, near net-shape components, with greater design flexibility than conventional processing, whilst being cheaper than other AM techniques.However, the deposition of material in layers can lead to a complex process history and non-ideal heterogeneous microstructures that exhibit microsegregation, columnar grain structures and banded heat affect zones, resulting from the overlapping thermal fields of individual melt tracks.
