When measuring residual strain distributions of thick structural components such as thick butt-welds using neutron diffraction, it is required to make a gauge volume larger as well as to shorten neutron path length in a material to obtain sufficient diffraction intensity. In this study, neutron attenuation effect on the strain measurement with large gauge volume was discussed based on the normal strain measurement of a thick butt-weld. As a result, it demonstrated potential of the neutron attenuation effects such as an apparent shift in strain distribution due to the influence of weighted average strain in a gauge volume. Attenuation correction methods were proposed as well to improve reliability of the neutron strain measurement with large gauge volume.
