Mechanical and Microstructural Characteristics of Rotary Friction Welded SS316L and Pure Copper with Added MWCNT Nano Additives

This study explores the novel design of geometric rubbing profiles on rotary friction welding for enhanced mechanical clamping in joining dissimilar alloys such as copper and stainless steel 316L. The behavior could hold yielding weld joint to a maximum level. An innovative approach effective mixing weldment zone be achieved through definition profiles. dispersion metallic phases governed by geometrical profile achieving intermetallic SS-Cu phase. Variations were made parameters like tool rotational speed, upset pressure, time, time find appropriate process four different profiles, namely helical fluke, plus, cylindrical, flat achieve reduction micro macro-structural defects with strong nugget. Results show that fluke seen have explicit values ultimate tensile strength 217 MPa (upset pressure), elongation 9.8 % average hardness 125 HV (friction pressure) at Microstructural characteristics prove formation IMCs grain size cementite increases Vickers weldment.
