Abstract
Residual stresses are one of the most important challenges to the safety of parts and structures. Considering the disadvantages of the traditional measurement of residual stress which are time-consuming, consumption, destruction, huge volume, Ultrasonic stress measurement installation is improved to meet the measurement of thin wall welded structure. The acoustical theory is introduced. Ultrasonic stress measurement experimental installation is designed. The longitudinal residual stress and transverse residual stress of twin wire welded plate are measured by the proposed system. The result of the ultrasonic method is verified by laser hologram interference hole-drilling method and finite element method. The measurement process by Ultrasonic method is not only nondestructive, but also real-time.
