초록
This paper investigated ultimate behaviors such as ultimate strength and weld metal fracture mechanism of austenitic stainless steel (STS304) and carbon steel (SS275) welded connections with TIG (tungsten inert gas) welding through test results. Main variables of specimens are weld length and welding direction against loading. Fractures of specimens were classified into tensile fracture and shear fracture in weld metal. Material properties of base metal and weld metal satisfied the minimum requirement of Korean Standard (KS). Strengths of TFW series specimens with transverse fillet weld got larger than those of LFW series specimens with longitudinal fillet weld. It is known that current design specifications such as ASCE, KDS and AISC did not provide accurate strength prediction for the dissimilar steel welded connections with weld metal fracture.
