As part of the project, Delphi will receive a $1.3 million grant to further develop Deformation Resistance Welding (DRW) and test its usefulness for welding different types of metals together in various configurations including tube to sheet and tube to tube.
The test results and process capabilities about the welding technology will be supplied to NASA, which will use the information to understand how DRW could be used to weld different types of metal structures on Earth and in space. Once the testing is complete and a research database developed, NASA could eventually use DRW to weld structures on the moon and Mars, if the in-space power required to accomplish the welds is small.
DRW is a resistance welding method developed to join metal tubes to solids, sheet metal and other tubes. The process atomically bonds metals and creates solid-state joints through the heating and deformation of the mating surfaces. DRW creates leak-tight joints capable of holding fluids or gases under pressure and heat, which can have strength exceeding that of the parent metals.
The DRW process, which was developed by
MRI is a not for profit organization created to speed the development of emerging technologies in the Life Sciences through collaborative programs in education, research and development and new company creation.
