Three kinds of welds were made using low frequency pulse current variable polarity tungsten inter gas (LPVPTIG) with argon shielding, direct current TIG (DCTIG) with helium shielding and high frequency pulse curr...
Tungsten inert gas (TIG) welded joints for 2219-T87 aluminum alloy are often used in the fuel tanks of large launch vehicles. Because of the massive loads these vehicles carry, dealing with weld reinforcement on TIG...

The local and global mechanical responses of gas tungsten arc welds(GTAW) of a 2219-T87 aluminum alloy were investigated with experiment and numerical simulation.Digital image correlation(DIC) was used to access t...
2219-T8 aluminum alloys were butt welded by the double-pass tungsten inert gas (TIG) arc welding process. The transverse tensile test of the joint showed that the fracture mainly occurred in the partially melted zo...
