Abstract:  
Shot peening improves property performance of welds and weldments by cancelling residual tensile stresses that develop in surfaces as welds cool and replacing them with compressive stresses. Compressive stresses raise resistance to fatigue, stress corrosion, and intergranular corrosion.
