Low Cycle Fatigue of Butt Weldments of HY-100(T) and HY-130(T) Steel.
Abstract
This progress report presents a summary of the studies conducted on the axial fatigue behavior of high strength steel weldments. The purpose of the current project is to continue the investigation of the axial fatigue behavior of HY-130(T) butt welds containing various types and density of weld defects, and to initiate studies of the fatigue response of plain plates and butt weldments of HY-100(T) steel. As part of the investigation of the effect of weld defects (porosity, slag, lack of fusion, etc.) on the fatigue behavior of the butt welds, the initiation and subsequent propagation characteristics of cracks originating at the various internal flaws are being studied; ultrasonic and radiographic inspection techniques are being used to identify the defects and to monitor the progression of internal fatigue cracking.
