Internal Stress Measurement of Weld Part Using Diffraction Spot Trace Method

Abstract:

The spiral slit-system was improved in order to make a gauge length regularity. The bending stress was measured by the improved spiral slit-system, and the measured stresses corresponded to the applied stress regardless of the diffraction angle. As a result, the validity of the improved spiral slit-system was proved. On the other hand, the diffraction spot trace method (DSTM), which combined the spiral slit-system and a PILATUS detector, was proposed to measure stress in a coarse grain. In this study, the distribution of the residual stress in a melt-run welding specimen was measured using the DSTM. The welding residual stresses measured accorded with that by the FEM simulation.
