    Abstract

    This study presents a comparison between contact and immersion ultrasonic method to measure welding residual stress of austenitic stainless steel plates (AISI 304L). Longitudinal critically refracted (LCR) waves are employed to measure the residual stresses. By using contact and immersion transducers, a 3D distribution of longitudinal residual stress for the entire of the welded plate is presented. A finite-element model of welding process, which is validated by the hole-drilling method, is used to verify the ultrasonic results. The results show no considerable differences between using contact or immersion transducers in ultrasonic stress measurement of stainless steel plates; however, some practical considerations are mentioned.
