Notes:
The purpose of this study is to find out the method to detect AE signals at around thenotch tip and to evaluate the AE signal characteristics for the basemetal, PWHT(post weld heattreatment) and weldment specimens of SA-516 steel during bend test. AE signals were produced inthe process of plastic deformation. AE signal strength and amplitude of the weldment was thestrongest, followed by PWHT specimen and basemetal. More AE signals were produced from theweldment because of the oxides, and discontinuous mechanical properties. The stronger AE signalstrength, amplitude and more AE event counts for the weldment were shown
