The National Science Foundation awarded a $215,254 Project Grant to the Regents of the University of Michigan under the Engineering federal grant program (CFDA 47.041) to research vibration-assisted laser keyhole welding. The university will test the hypothesis that applying vibration to the laser during keyhole welding can significantly improve joint properties by reducing porosity, refining grain structure, and reducing intermetallic compounds. In-process monitoring, post-process characterization, and multi-physics modeling will be used to understand how vibration impacts laser-matter interaction, keyhole dynamics, thermo-fluid flow, and solidification. Outreach activities are also planned to engage students and communities. The research aims to advance scientific understanding of the welding process and enable improved productivity and performance in manufacturing industries such as automotive and aerospace. The award period is from December 1, 2021 through March 31, 2023.
