Effect of Various Fluxes on Different Metals and Alloys in A-TIG Process: A Review

Welding is the process of coalescence two metals/alloys for creating a seamless joint, quintessential fabrication utilised in almost every manufacturing sector. There range welding processes that are used according to their features and requirement fabricator. The tungsten inert gas (TIG) an extensively owing its inherent characteristics like high weld quality, surface cleanliness, autogenous mode. Unfortunately, TIG suffers some drawbacks, most pronounced one shallow bead low depth penetration (DOP). This renders unusable thicker sections single pass consequently requires multiple passes which adds expenditure. A modification this A-TIG where stands Activated, method utilises activating flux material augment width ratio (DWR) bead. current work comprehensive focuses mainly on basics process, understanding pool dynamics governing penetration, analysis various materials effects different finally outcomes fetched from using commercially important alloys.
