Austenitic stainless steels have excellent corrosion resistance, durability, aesthetic appeal, fire resistance etc. compared with ferritic stainless steels and so especially 304 stainless steels have been utilized widely in the exterior member of building structure. In this paper, ultimate behaviors such as ultimate strength and fracture mechanism of fillet-welded connections with TIG(tungsten inert gas) welding have been investigated through test results. Main variables of specimens are weld length and welding direction against loading and ultimate strengths were compared according to the variables.
