  By Premkumar P, Sanjay P, Rajavendhan R, Ashwin Prabu G, Murali P., Dinesh S, Adinarayanan A

  Abstract: The problem of high-performance dissimilar joints and their compatibility with polymer and composite engineering applications is the impetus to the current work. This paper seeks to investigate the possibility of applying the polymer-based composite ideas with underwater friction stir welding (UWFSW) to improve the performance of AA5083 aluminumcopper joints. To achieve this a systematic experimental method was followed by varying the tool rotational speed, traverse speed and tilt angle and …
