This study investigates structural behaviors such as ultimate strength and weld metal fracture mechanism of carbon steel (SS400) fillet-welded connections with shielded metal arc welding (SMAW) through monotonic tensile test. Specimens of TFW series (transverse fillet weld against loading direction) and LFW series (longitudinal fillet weld) failed by tensile fracture and shear fracture, respectively in the weld metal of connections. Test strengths of specimens were compared according to welding direction and weld length.
