THE EFFECTS OF BASE METAL NOTCH ORIENTATION AND ACUITY AND WELD POROSITY ON THE DYNAMIC TEAR TOUGHNESS OF A514F STEEL

The effects of weld porosity on the dynamic tear properties of 514F steel butt welds were assessed in a program which conducted dynamic tear tests in six areas of experimentation: (1) the base plate steel in the longitudinal and transverse orientations; (2) sound weld metal; (3) weld metal containing clustered porosity; (4) weld metal containing linear porosity; (5) stress-relieved weld metal; and (6) base metal in the longitudinal and transverse directions having fatigue precracked notches. /Author/
