The effects of cluster porosity on the tensile properties of A514 steel butt weldments were assessed. Cluster porosity was measured both in terms of the actual total area of pores and of the area of the cluster (including metal ligaments, or webs, that connect pores). Results showed that the tensile strength of the welded metal is not significantly reduced if the area of pores and the cluster area are below critical sizes; however, ductility is rapidly reduced until these sizes are reached. Consideration of the implications of tensile test data on both working stress design and limit stress design indicates that relaxation of welding codes may be considered for certain tensile loading applications if the codes are based on working stress design. This would be beneficial in terms of reduced project costs for weld rework. Relaxation of codes based on limit stress design should not be considered for the conditions of porosity covered in this study.
