Abstract Details

2022, Doctor of Philosophy, Ohio State University, Welding Engineering.
The desire to industrialize and expand the envelope of laser powder bed fusion (L-PBF) additive manufacturing (AM) has driven development of multi-laser PBF (ML-PBF) technology. Stitching or the overlapping of areas consolidated by a single laser is needed to ensure part integrity in these systems. While stitching of large parts by multiple lasers has become a reality, the process to structure to property relationships have yet to be well understood. The core concepts of weldability will be applied to investigate the process to structure to property relationships for ML-PBF stitching of nickel super alloys. Through this investigaton alternative processing and post-procesing strategies will explored to understand how ML-PBF machines can be most robustly utilized for making critical components. By characterizing these relationships, further adoption and industrialization of ML-PBF can be confidently achieved.
