The National Aeronautics and Space Administration (NASA) granted Dr. Wei Li of The University of Texas at Dallas $748,958 for his project on Integrated Computational Materials Modelling Framework for Investigating the Process-structure-property Linkage of the Lunar Metal Welding with Internal Defects. The main goal of this project is to better understand and reduce welding defects that form in metal joints under lunar environmental conditions, such as intense vacuum, temperature fluctuations, condensed gravity, and rough lunar dust such as regolith.

Inner welding defects like internal gaps and fusion defects weaken metal components, which threatens lunar structures. This research project uses a multiphysics framework to replicate imperfection development and advancement, analyzing their impact on material texture and properties in welded joints. This project also incorporates Earth and space-based welding data to develop a predictive model for enhancing welding parameters, aiming to improve space metal construction. Dr. Li’s research will contribute to the field of mechanical engineering and materials science.
