Abstract : An evaluation of the axial fatigue behavior of plain plates and full penetration butt-welded joints in HY-130(T) steel is presented. Fatigue tests were conducted with sound weldments and and weldments containing internal defects including slag, porosity, and lack of fusion. Radiographic and ultrasonic inspection techniques were used to study the initiation and propagation of fatigue cracks originating at internal weld flaws. Acoustic emission measurements were taken for smooth and notched HY-130(T) specimens tested in static tension and in fatigue. The results of preliminary tests of plain plates and butt weldments of HY-100(T) (HY-110) steel are presented. (Author)
