VIBRATIONAL RESIDUAL STRESS RELIEF IN A PLAIN CARBON STEEL WELDMENT

In the present work, attempts were made to reduce the residual stresses due to circumferential welding in a disc shaped test sample of a plain carbon steel (AISI 1018) through the application of resonant elastic vibrations. The magnitudes and the distribution of residual stresses in samples that were vibrated and not vibrated were determined by a modified Sachs boring-out technique. Results show that high strain amplitude vibrations do significantly lower the residual stresses in areas of high residual stress. In areas outside the areas of high residual stress, the residual stresses may be reduced or not affected. Implications for the use of vibrational stress relief are discussed.
