About
M. Vishnukumar is a materials and manufacturing researcher whose work focuses on advancing welding and surface engineering techniques for industrial repair applications. His key research areas include weld overlay deposition, microstructural characterization, and electrochemical evaluation of stainless steel components. Vishnukumar’s most cited paper, “Microstructure and electrochemical evaluation of ER-308L weld overlays on AISI 321 stainless steel for repair applications” (2022, 17 citations), demonstrates his significant contribution to developing cost-effective repair solutions for critical stainless steel structures. In this work, he employed robotic gas metal arc welding to deposit ER-308L overlays, revealing the formation of dendritic microstructures that influence both mechanical integrity and corrosion resistance. This research has direct implications for extending the service life of components in industries such as chemical processing, power generation, and aerospace, where material degradation is a major concern. By integrating microstructural analysis with electrochemical testing, Vishnukumar provides a comprehensive framework for evaluating repair weld quality. His work is particularly valuable for engineers and researchers seeking economical alternatives to component replacement, and his findings continue to inform best practices in weld repair metallurgy.
