About
Dr. N. Murugan is a leading figure in advanced manufacturing, whose research centers on the microstructure, mechanical properties, and process optimization of metallic components produced through additive and welding-based techniques. His most impactful work explores wire arc additive manufacturing (WAAM) as a cost-effective, scalable method for fabricating large-scale, near-net-shape components. In a seminal 2020 study (60 citations), Dr. Murugan demonstrated the successful fabrication of an Inconel-625 slab using robotic metal inert gas welding, critically analyzing the resulting microstructure and mechanical performance to validate WAAM’s potential for reducing the buy-to-fly ratio in aerospace and energy applications. This contribution has provided foundational insights for engineers seeking to replace traditional subtractive methods with efficient additive routes for high-value alloys. Beyond this, his broader body of work addresses challenges in weldability, post-process heat treatment, and material characterization for nickel-based superalloys. Dr. Murugan’s research is widely cited by materials scientists and manufacturing engineers, reflecting its practical relevance in advancing robust, large-format additive manufacturing for demanding industrial sectors.
