<![CDATA[Piping systems are essential components in various industrial sectors, ensuring the safe and reliable transportation of fluids. The quality of welded joints plays a crucial role in maintaining structural integrity and system reliability. Although research on piping system welding continues to grow, comprehensive information regarding publication trends, author productivity, collaboration patterns, and research themes remains limited. This study aims to analyze the development of piping system welding research using a bibliometric approach. The data were collected from the Scopus database, yielding 136 documents published between 2021 and 2024. The analysis was conducted using Bibliometrix through Biblioshiny and visualized with VOSviewer. The results indicate that China has the highest publication contribution, while research themes have shifted from general welding processes toward pipeline corrosion, fracture mechanics, welded joint integrity, and gas piping systems. This study provides a comprehensive overview of research development, collaboration patterns, and future research directions in piping system welding.]]>
