About

N. Pravin Kumar is a materials and welding engineer whose research focuses on advanced hardfacing and weld overlay technologies, with particular emphasis on corrosion-resistant alloys and stainless steel repair applications. His most influential work, garnering 54 citations, investigates nickel-based Inconel 625 hard overlays deposited on AISI 316L stainless steel plates using gas metal arc welding (GMAW)-based hardfacing processes, contributing valuable insights into wear and corrosion protection for industrial components. His subsequent research explores the microstructural and electrochemical behavior of ER-308L weld overlays on AISI 321 stainless steel, utilizing robotic GMAW setups to advance precision repair methodologies for structural applications. This work, which has accumulated 17 citations, reveals critical dendritic microstructural features that inform the performance and reliability of repaired components. Collectively, Kumar's contributions address real-world industrial challenges in material degradation, offering economical and technically robust solutions for extending the service life of engineering structures. His work bridges fundamental metallurgical analysis with practical welding applications, making it a meaningful resource for researchers and engineers working in surface engineering, welding technology, and materials science.
