Activated flux tungsten inert gas welding process to improve penetration in copper material

Abstract

TIG welding using activated flux or A-TIG welding developed at paton welding institute in 1960. This process can give us higher penetration than conventional process in single pass. High penetration capability of this process attracts the researchers to work on this phenomenon. Recently In my present work, attempts have been made to investigate and review the literature paper published with respect to (1) Mechanisms which explain the reasons for high penetration achieved using A-TIG, (2) effect of process parameters on welding response for A-TIG, (3) effect of various alloying elements in ferrous and non-ferrous metals on penetration achieved by A-TIG, (4) feasibility investigative studies of A-TIG onnon-ferrous metals. In consideration of the above, this research will help in (a) presenting the opportunity of research in A-TIG for copper material to aggrandize its industrial application and (b) to generate stepwise understanding of various factors describing the capability of this process.
