THE EFFECT OF FLAW SIZE ON THE FATIGUE STRENGTH OF WELDED JOINTS IN HIGH-STRENGTH STEEL

The results of an experimental investigation into the effects of typical weld flaws on the fatigue strength of welded joints in StE 47 (plate thickness 12 mm) and StE 70 (plate thickness 10 mm) welded by MAG welding (carbon dioxide) using cored wire are reported. The flaws investigated included weld reinforcement, root concavity, edge misalignment, undercutting, end craters, porosity, slag inclusions, lack of root fusion, and arc strikes. Recommendations are made for permissible sizes of flaw for different grades of weld.
