A study done through the SAE Fatigue Design and Evaluation Committee showed what shot peening can do for
welds compared to welds that didn’t have this operation done. The study claimed that the regular welds would fail
after 2,50,000 cycles, while welds that had been shot-peened would fail after 2.5 million cycles and that too outside

Shot peening practices are highly controlled by both proprietary and industry-standard specifications. There are many cases where industry standards, such
as SAE J442 and J443 or AMS 2430,
