About
Feilong Ji is a researcher specializing in advanced welding and additive manufacturing processes, with a focus on robotic gas metal arc welding (GMAW) and directed energy deposition (DED) techniques. His work centers on understanding molten pool behaviors and their influence on forming quality, particularly when welding complex surfaces across varying positions—a critical challenge for industrial automation. His most-cited paper (2021, 95 citations) provides foundational insights into how process parameters affect weld appearance and stability in robotic GMAW, offering practical guidance for improving manufacturing precision. More recently, Ji has explored the fabrication of bimetallic hierarchical structures, combining hot-working tool steel with martensitic stainless steel via DED-arc/wire processes. His 2023 study (28 citations) demonstrates how these hybrid materials can achieve tailored microstructures and mechanical properties, opening new possibilities for high-performance tooling and wear-resistant components. Ji’s contributions bridge fundamental process physics with applied materials engineering, making his work valuable for researchers and engineers seeking to optimize metal deposition for complex geometries and multi-material designs.
