Residual stresses have been shown to be a major factor contributing to intergranular stress corrosion cracking of weldments in austenitic stainless steel. Residual stresses developed during welding are measured for three pipe sizes including 4-, 10-, and 26-inch-diameter, schedule-80, type-304 stainless steel. Significant differences are found in both magnitude and distribution as a function of pipe size. Effects of preweld surface treatments are also evaluated.
