Analysis of TIG-MIG Hybrid Welding and Its Impact on Mechanical and Microstructural Integrity: A Comprehensive Review

The Tungsten Inert Gas (TIG)-Metal Inert Gas (MIG) hybrid welding, is a novel welding process that combines the precision of TIG welding and the efficiency of MIG welding to offer improved weld quality. The call to extend the depth and breadth of the TIG-MIG hybrid welding research for a better understanding of its weld integrity, material types, and application in academics and industries is evident in past studies. This article aims to comprehensively analyze the evolved properties of the TIG-MIG hybrid welding process and its adoption in academic and industries, which have not received much attention in previous studies. In addition, the challenges limiting its process adoption are also enumerated. Systematic and bibliometric approaches were adopted for this study. Research data was gathered from the Scopus database. Bibliometric analyses show the growing academic interest in this technique, recognizing its potential to enrich welding technology education and research. Despite its advantages, challenges such as the complexity of the relationship between input variables and corresponding responses and the requirement for dual-skilled personnel pose a limit to its adoption in industry and academics. In addition, there are also limited studies that optimize the welding process.
