The shearing and tensile strengths and deformation capacities of the partial penetration welded joints have been studied experimentally. The main results obtained are as followings; (1) The strength coefficients for the yield and maximum shearing strengths of the welded joints show the size effect in the cases of SM490, TMCP325, and HT590 steels, however, these strength coefficients are almost constant with throat thickness in the case of HT780. (2) The strength coefficient for the maximum tensile strength decreases with the increase of the ratio of throat thickness to plate thickness even in the case of HT780. (3) The strength coefficients for the yield and maximum tensile strengths of the cross welded joints are larger than these coefficients of the butt welded joints owing to the multi-axial stress state of the cross welded joint.
