A Characteristic Study of Weld Residual Stress Measurement for AISI 304 Plate Surface Weld Specimen

AISI 304 표면용접평판 시편의 용접잔류응력 측정 특성 연구

This study is performed to compare characteristics of various measurement technique for weld residual stress. AISI 304 plate with one path weld on the surface was manufactured for this study. Hole drilling method, X-ray diffraction method and instrumented indentation method were used to measure the residual stress before and after welding. All the results were compared and analyzed.
