Abstract

The present work examines the significant impact of resistance spot welding (RSW) process parameters on the properties and efficacy of connections created in sheets of 316L stainless steel. This study examines the intricate relationship between welding parameters, investigating their influence on the microstructure, mechanical characteristics, and overall efficacy of welded connections. By employing a methodical experimental methodology, this study thoroughly investigates the impact of different factors in resistance spot welding (RSW), including welding current, welding time, and electrode force, on the resultant weld quality. The objective is to comprehensively understand both the individual and combined effects of these parameters. The utilization of microstructural analysis is implemented to reveal the complexities associated with the creation of the nugget. Additionally, mechanical testing is utilized to gain a deeper understanding of the strength, ductility, and toughness of the welded joints. The scope of the inquiry goes beyond traditional evaluations, as it incorporates sophisticated procedures to assess the corrosion resistance and fatigue performance of the welded 316L sheets. The objective of this study is to optimize the welding process to improve immediate performance and gain a comprehensive understanding of the long-term durability of the joints in demanding operating conditions. The thorough investigation of resistance spot welding (RSW) parameters and their influence on the integrity of 316L sheet joints provides significant insights for industries that heavily rely on durable welded structures, including aerospace, automotive, and chemical processing sectors.

Keywords: Resistance spot welding, 316L stainless steel, welding parameters, microstructure, mechanical properties, corrosion resistance, fatigue behavior, joint performance, optimization, welded structures
