Biography
Glenn Daehn’s research, education and service efforts are all broadly related to the interwoven themes of Midwestern manufacturing revival, which in turn depends on technology development, integration of the University mission with regional industry and the development of a world-class workforce that is both smart and creative as well as able to make things.
Recently, most of Glenn’s research is focused on impulse-based manufacturing. This technology allows new ways of shaping, cutting, joining and processing materials.
Glenn is passionate about connecting kids in the K-12 pipeline to careers in the STEM fields (at all levels, not just professional engineers). Since 2007 he has been very involved in the ASM Materials Camp for Teachers program and since 2010 has been a trustee on the ASM Education Foundation Board. Since 2012 he has been involved in the professional development of practicing high school science teachers through the Math Science Partnership Program.
Glenn has been involved in a range of activities that encourage deep interaction between academia and industry. He was the founder and is the current Director of the Ohio Manufacturing Institute. He is part of OSU’s leadership team for the Lightweight Innovations for Tomorrow Institute, founded by EWI, University of Michigan and Ohio State. He leads the Agile Manufacturing and Low Cost Tooling pillar. He also plays central roles in Ohio State’s manufacturing initiatives including the Center for Design for Manufacturing Excellence and the Materials and Manufacturing for Sustainability Discovery Theme Initiative.

Lightweighting Goes Beyond the Low-Hanging Fruit
Advanced Manufacturing

The technology is intended as a way to join dissimilar materials and avoid corrosion. “It’s an early stage technology we’re committed to,” Glenn Daehn, professor of metallurgical engineering, said last week at the Lightweight Vehicle Manufacturing Summit in Detroit...
New Welding Technique Creates Stronger, 'Greener' Cars
Laboratory Equipment
2015-10-29
Despite recent advances in materials design, alternative metals still pose a challenge to manufacturers in practice. Many are considered un-weldable by traditional means, in part because high heat and re-solidification weaken them, said Glenn Daehn, professor of materials science and engineering at Ohio State, who helped develop the new technique. “Materials have gotten stronger, but welds haven’t. We can design metals with intricate microstructures, but we destroy the microstructure when we weld,” he said. “With our method, materials are shaped and bonded together at the same time, and they actually get stronger.”...

Turning Ohio State research into commercial products
The Ohio State University2015-11-05
Glenn Daehn, professor of materials science and engineering, and Anupam Vivek, senior research associate. They have developed an impact spot welding technology for high strength metals that will be used in lighter-weight automobiles. The new technique consumes one-fifth of the energy of resistance spot welding, yet creates bonds that are commonly twice as strong...
Ohio State researchers have invented a way to weld “un-weldable” metals—Ask the lead engineer anything!
The Ohio State University2015-11-04
Glenn Daehn, professor of materials science and engineering, and his team have invented a technique that welds aluminum to steel using 80 percent less energy than a typical welding system, while creating bonds that are 50 percent stronger. Seen under a microscope, the bonds often feature delicate curlicues where veins of both materials extend outward and wrap around each other...
