Abstract

Using a complex limit stress diagram, we determine nondamaging conditions of vibration treatment of steel 20 welded joints, which ensure a decrease of residual stresses down to 0.5 of the yield strength of the material. We carry out comparative fatigue tests of specimens with high levels of residual stresses after vibration and thermal treatment and analyze the test results.
