Resumen

This work applies to the production of large, complex, metallic preform structures in the aerospace and tool and die industries. In the aerospace industry, this technology has a potential role in the rapid production of custom, near-net shape preforms for machined Ti-6Al-4V components. Specifically, site-specific control enables localized control of bead geometry, which has enhanced defect mitigation capabilities and may enable local control of material properties.
