ABSTRACT
In this study, key advances and recent developments in the performance of Gas Tungsten Arc Welding (GTAW) and Gas Metal Arc Welding (GMAW) technologies are discussed. GTAW is a clean, precise welding technology utilised for years to make superior-quality joins in a range of materials. GTAW innovations increased due to industry interest in welding mid-thick section components. This article describes various variants of GTAW and their mechanisms to understand how weld penetration depth improves during welding. GTAW is slower than GMAW, but its welds are cleaner and require less polishing because there is no spatter. GTAW provides high control and a nice root profile with mechanical and corrosion qualities. The most commonly used shielding gases for GMAW are argon, carbon dioxide, and a mixture of the two. This article also focuses on the advancements in the GMAW process. Small changes to the initial procedure led to improved and more tailored outcomes in the variants, which eventually replaced GMAW. Thus, the impacts of changes in some parameters will be demonstrated. This offers the possibility of implementing these versions in many industrial contexts. Thus, this chapter will boost welding research for industrial use and capabilities.
