About

Paul Denney is a materials and manufacturing researcher whose work spans advanced welding technologies and additive manufacturing processes. Based at the Applied Research Laboratory at Pennsylvania State University, Denney has made significant contributions to the field of laser-based fabrication, particularly in developing innovative techniques for structural and aerospace-grade materials. His most influential work, "Laser Welding of Lightweight Structural Steel Panels" (1993), garnered 20 citations and demonstrated a pioneering low heat input, high-power CO₂ robotic laser beam welding technique for fabricating corrugated core steel sandwich structures using HSLA 80 and Type 316L stainless steel. This research addressed critical needs in lightweight structural fabrication with broad implications for naval and industrial applications. Denney also advanced the understanding of energy efficiency in emerging manufacturing processes, as evidenced by his 2016 paper on Laser Hot-Wire (LHW) cladding, which explored the thermodynamics of combining dual heat sources for wire-based robotic cladding and its potential as an additive manufacturing technology. Together, these contributions reflect a career dedicated to pushing the boundaries of precision joining and deposition technologies, offering practical solutions for modern manufacturing challenges.
