A bibliometric review of A-TIG welding: unveiling global research trends
摘要
Activated Tungsten Inert Gas (A-TIG) is a process aimed at increasing the efficiency of the conventional Tungsten Inert Gas (TIG) process through the use of a flux that concentrates the welding arc and modifies the physicochemical properties of the weld pool. The results of a scientometric analysis, including bibliometric analysis using VOSviewer and Biblioshiny, conducted on a dataset of 457 publications related to A-TIG and indexed in the Web of Science database, were presented. Complementary analyses were performed, encompassing publication and citation trends, journals, countries, authors, funding agencies, and research areas. An unbiased analytical approach led to a balanced evaluation of the current state of knowledge in the field of A-TIG and made it possible to identify global research directions and existing gaps as well as future research needs. This approach enabled the identification of key emerging research areas in A-TIG, such as optimization of flux composition, research on deep penetration mechanisms, application of artificial intelligence and optimization methods. Additionally, pressing research priorities include standardization of flux compositions, simulation studies on fluid flow and convection in the welding pool, influence of active flux on the technological and operational performance of welded joints.
