About

Dr. P. Narayanasamy is a materials and manufacturing researcher whose work centers on advanced welding processes, particularly for high-performance alloys. His key research areas include pulsed gas metal arc welding (GMAW), process parameter optimization, and the mechanical characterization of welded joints. Dr. Narayanasamy’s major contribution lies in demonstrating the effectiveness of automated DC-pulsed MIG welding for joining Monel 400 sheets, a nickel-copper alloy known for its corrosion resistance. His most cited paper (2023, 8 citations) systematically applies an L9 Taguchi array to optimize robotic welding parameters, achieving high-quality welds with ERNiCu-7 filler. This work provides a practical framework for industry, reducing trial-and-error in welding parameter selection. Beyond this, his research has explored similar optimization strategies for other challenging materials, contributing to the broader field of automated welding. With a growing citation impact, Dr. Narayanasamy’s studies are valuable references for engineers and researchers seeking to improve weld integrity and process efficiency in demanding applications.
