The Effects of Clustered Porosity on the Shear Strength of A 514F Transverse Fillet Welds.

Abstract

This report presents the results of a study of the effects of clustered porosity on the transverse shear strength of A 514F steel weldments. The amount of porosity induced into the specimens ranged from zero to over 20 percent of the fracture surfaces. Results indicate that clustered porosity, up to about 10 percent, has little effect on the shear strength or ductility of transverse shear welds. A slight decline in shear strength was observed for larger amounts of porosity. Results also indicated that secondary defects in the fillet welds which were undetected by x-ray radiography reduced strength below that found in the specimens containing porosity only. (Author)
