Welding is a fabrication process that involves melting the ends of two metal objects at high temperatures until they fuse together. Friction stir spot welding (FSSW) represents a significant advancement in friction welding technology, designed to replace traditional spot welding techniques, such as resistance welding. This research focuses on FSSW by examining the parameters that influence its mechanical and chemical properties, which include tool rotational speed (RPM), tool geometry, tool diameter, pin dimensions, and chemical aging all of which play a crucial role in determining the welding outcome. By varying these parameters, optimal welding results can be achieved. A bibliometric analysis conducted using the Scopus database and specific search keywords yielded a total of 768 articles related to FSSW. The publication of articles on this topic has steadily increased since 2005, reaching its peak in 2022. This upward trend highlights new research opportunities aimed at enhancing welding technology, particularly in friction stir spot welding, which offers several advantages over conventional resistance welding techniques. China leads the world in FSSW publications with an impressive total of 700 articles, followed by Japan, India, the USA, and Iran. Furthermore, China has the highest collaboration rate with international researchers and holds the most citations in this field, totaling 2,264, while the USA and Canada follow with 1,468 and 1,397 citations, respectively. Among the individual articles, Kubit’s work stands out with the highest number of citations, totaling 253. The most frequently used keywords in the FSSW research literature include “friction,” “welds,” “aluminum,” “welding,” and “mechanical properties,” reflecting the key areas of interest and demand in this evolving field.
