Examining Stress Modification in Dissimilar and Similar Metal Welds through Ultrasonic Impact Treatment

Residual stress (RS) from welding poses major challenges, especially in dissimilar joints such as 1018 steel and 304 stainless steel, where thermal expansion mismatches intensify tensile stress. Conventional post-weld heat treatments, although effective for homogeneous materials, often require substantial energy, speci...
