Recent Development in Friction Stir Welding: An Advancement in Welding Technology

Friction stir welding (FSW) has various applications focused on the different industries because of its efficiency and sustainability. The main different sectors of industries where FSW technique is utilized are automobiles, aerospace, shipbuilding and railways. This current experimental study describes about the background of the FSW technique and recent advances in welding technology which have occurred during the last few years. Furthermost, the development endeavored to conflict the problem of non-uniformity in temperature distribution in weld zone pinhole, which is left after the welding process in FSW. During the last two decades, many researchers have been working on the advanced welding technology of FSW because this technique could be made more optimized and sophisticated by using proper tool during the welding process. The application of various parameters such as tool rotation, plunge depth, feed rate, shoulder diameter of tool and tool pin geometry has made FSW process more uniform. Friction stir welding process is a cutting edge technology widely used nowadays throughout the globe for welding because of its very high strength. The joint formation in the process has a wide application in welding of two dissimilar materials, e.g., aluminum and steel. In this research paper, an attempt is made to provide some directions for future development in the friction stir welding technology.
