Book Description
The results of the investigation indicate that 5083-5183 welds subjected to fatigue are little affected by porosity if the weld reinforcement is left in place. The weld reinforcement itself is the critical and fatigue limiting notch. Most welds tested with their reinforcement removed gave longer fatigue lives than as-welded tests regardless of porosity level. Porosity most influenced the fatigue lives of the reinforcement removed tests at the lowest stress levels. The radiographic standards currently in use by the U.S. Navy were found to be effective in insuring superior results with reinforcement removed welds. Conversely, few reinforcement removed welds which failed these standards gave shorter fatigue lives than porosity-free, as-welded welds.

Book Description
The lack of penetration defects (LOP) can substantially reduce the fatigue life of these welds. The largest defects reduce the fatigue life the most. At 19 ksi., the largest LOP (2a approximately equal to 0.15 in.) can reduce the fatigue life from 80,000 cycles to 2,000 cycles. At 12 ksi., the largest LOP can reduce fatigue life from 4,000,000 cycles to 8,000 cycles. In most cases, the LOP had porosity associated with them. The fatigue crack initiation site usually includes these pores; consequently, the above data reflects the fatigue resistance of LOP with associated porosity.
