Limitation in depth of penetration is a concern in conventional tungsten inert gas (TIG) welding process. To improve penetration capability of TIG process, flux bounded TIG (FBTIG) has been recently developed. Tensile strength of FBTIG welds of aluminum alloy AA2219-T87 is investigated in the present study and compared with that of conventional TIG welds and base metal. Tensile strength of FBTIG weld was found to be better than conventional TIG weld due to fine grain structure of FBTIG welds.
