The fatigue life of butt-welded joint specimens under oblique loading was experimentally investigated. Five types of specimens with different oblique butt-welding angles were used for the fatigue tests and subjected to the fixed-directional loading to stu The fatigue life of butt-welded joint specimens under oblique loading was experimentally investigated.
