Research on Welding Residual Stress Measurement by Using Ultrasonic Technology

摘要：

　　An ultrasonic method was developed to measure the residual stress in a welded joint based on the modified acoustic-elasticity theory.Phase-frequency analysis method was introduced by incombination with shear wave and longitudinal wave.The acoustic-elasticity parameters of joint material was derived by ultrasonic inspection during loading experiment.Transverse and longitudinal residual stress was determined by precisely measuring of short-distance acoustic travel time.The ultrasonic measurement results was confirmed by H&K theory and XRD methods with good repeatability and reliability.
