Flux bounded tungsten inert gas welding for enhanced weld performance-A review

Flux Bounded Tungsten Inert Gas welding (FBTIG) is considered to be a variant of Activated Tungsten Inert Gas welding. Though Activated Tungsten Inert Gas welding (ATIG) is widely popular among scientific community, it lacks the versatility to be adapted by various industries because of its inherent demerits. The present study explores the growth of the FBTIG welding process, right from its inception to its current stature. The mechanisms associated with the FBTIG welding process for increased depth of penetration. is elaborated. The process variables are identified and its effects on the weld bead geometry were discussed. The choice of fluxes for FBTIG welding process and their contribution to enhancement of weld penetration was discussed. This study also highlights the merits of this process and its adaptability to various industries. (C) 2017 Published by Elsevier Ltd on behalf of The Society of Manufacturing Engineers.
