Wire arc additive manufacturing (WAAM) is a technique of building up parts layer by layer of using wires as feedstock and arc as heat source. It has become an alternative manufacturing method for large and expensive metal components that features high buy-to-fly ratios. To date, WAAM has successfully been used to produce large components with complex structure. In this research, WAAM has been applied to fabricate Ti-6Al-4V bulk materials using Ti-6Al-4V wires. The effects of the inter-pass temperature on the bead geometry, microstructural evolution and mechanical properties of WAAM fabricated Ti-6Al-4V have been invvestigated.
