A Contemporary Review on Friction Stir Welding of Circular Pipe Joints and the Influence of Fixtures on This Process

The permanent metal joining processes play a vital role in assembling the complex aluminium structures of aerospace, automotive, marine, and oil industries. invention friction stir welding (FSW) redefined mechanism to produce high-quality welds by eliminating consumption electrodes shielding gases, resulting economical processes. Research works still lack explore application FSW geometries. In this view, present work reports critical review various geometries welded FSW, mainly circular that are majorly used gas aspects pipes, such as process facilitation, parameters, tool material selection, design selection discussed. paper also presents insights into parameters responsible for weld quality, feasibility optimization techniques, status fixture arrangements. facilitation requisites pipes provided based on reviews made. concludes discussing challenges associated with economic aspects, future research directions.
