Activated flux induced Tungsten inert gas welding of Ferrous alloys - A Review

Abstract Ferrous alloys are employed in a range of fields, including aerospace, construction, automobiles and chemical processing. One the most used welding processes for fusion ferrous metals is gas tungsten arc (GTA) or Tungsten Inert Gas (TIG) welding. Due to lower amount penetration accomplished using only one pass, less frequent some industrial situations. Fluxes have been discovered improve depth GTA welding, resulting increased productivity. The research on Activated flux induced TIG (A-TIG) discussed this publication. effect fluxes during weld parameters morphology, usage dissimilar welds all study. mechanisms involved enhancement depth, types used, mechanical properties microstructures discussed. study also gives an insight areas explored.
