About

R. Arulmani is a leading researcher in advanced manufacturing, specializing in wire arc additive manufacturing (WAAM) and the characterization of high-performance alloys. His work focuses on developing reliable, large-scale fabrication techniques that dramatically reduce material waste, particularly for aerospace and industrial applications. Arulmani’s most cited paper (2020, 60 citations) demonstrates his foundational contribution: fabricating an Inconel-625 slab component via robotic gas metal arc welding, systematically evaluating its microstructure and mechanical properties to validate WAAM as a cost-effective alternative to traditional subtractive methods. This study has become a key reference for researchers seeking to optimize nickel-based superalloy production. More recently, he extended his approach to Stellite 6 alloys (2022), producing prototype parts and assessing their performance, further broadening the material scope of WAAM. By combining robotic automation with rigorous metallurgical analysis, Arulmani has advanced the practical deployment of additive manufacturing for complex, load-bearing components. His work is essential reading for engineers and students exploring sustainable, high-precision fabrication of superalloys.
