Fatigue of Iron Base Alloys HY-80 Steel Cast Tees Butt Welded to Rolled Section Single and Double Weld Joint Design

摘要

The average fatigue life of 1 5/8 in. thick cast tee butt welded to rolled plate is approximately the same as that of cast plate butt welded to rolled plate and rolled plate butt welded to rolled plate. At 80,000 psi nominal stress range the fatigue life of these butt welds is approximately 20,000 cycles. No significant difference in the fatigue life of single and double vee butt joints can be estimated because the differences in fatigue life represent normal scatter of fatigue data, and because the amount of data is limited.
