Abstract:  
Results of tests on HY-80 fillet welds at stress levels in the 60,000 to 180,00 psi range (0 to tension) have indicated that the fatigue lives of these weldments approximate those of prime base plate. The process is inexpensive and readily applicable to existing and new construction with currently abvailable equipment and skills. Potential significant improvement of properties of welded structures, in addition to fatigue, might also be realized.
