Abstract

This paper investigates ultrasonic method in stress measurement of a pressure vessel made of austenitic stainless steel 304 L. Longitudinal critically refracted (LCR) waves are employed to measure the welding residual stresses. The acoustoelastic constant is measured through a hydro test while the pressure vessel is kept intact. Hole-drilling method is used to verify the results of ultrasonic measurement corresponding to axial and hoop residual stresses of the pressure vessel. The results show good agreement between hole-drilling and ultrasonic stress measurements which is accomplished nondestructively.
