Impact of activated–flux tungsten inert gas (a-tig) welding on weld joint of a metal – Review

Welding is applied in every industry and it's a major method of manufacturing and revamping metal products because its generally economical, efficient and reliable as a means of joining together metals. Various ways have been proposed to improve the process ranging from adjusting the various welding parameters like welding current, voltage, arc length, width, type of shielding gas used, to using arc pulsing. The method that has however gained the most attention is the Activated-flux TIG welding process which utilizes welding flux to help reduce the bead width and increase the weld penetration. In order to improve the TIG welding process's industrial efficiency and penetration ability, one method commonly applied is the use of activating flux with the welding process. This review provides insight to the impact of Activated - Flux Tungsten Inert Gas Welding on weld joint of a materials metal. (paper)
