IMPROVING THE FATIGUE PERFORMANCE OF WELDED ALUMINUM ALLOYS

Postweld brush shot peening improves the fatigue performance of butt-welded 5086-H116 (with the weld reinforcement removed) to the level of unwelded base metal and can increase the fatigue strength of 5086-H116 fillet welds from 5,500 to 10,000 psi at 10**7 cycles. The ability to conduct the peening operation in an aluminum ship structure makes brush peening an attractive method both in new construction and during repair.
