The elastic and plastic behaviors of end fillet welds were investigated using T-joint specimens. The fillet size, amounts of off-set and gap of welded plates were changed in series. The stress-strain relations of joints were compared with the base plate, and the following results were obtained for 16mm thick specimens investigated. (1) The T-joint with the fillet size of 12mm or less exhibited inferior rigidity to base plate. The performance of a larger sized one was satisfactory. (2) A large off-set of tension plates injured the rigidity of joint. For instance, for 14mm size weld, it should be limited under 4mm in order to effectively transmit the tensile stress of plates about 10kg/mm^2. (3) The fillet size should be enlarged by the distance of gap between plates. Further it was proved that the angle of fracture was larger for the fillet initially broken than the one broken in the next place.
