Correlative investigation of weld line. a Absorption, b average scattering, c degree of anisotropy, and d retrieved projected fibre orientation images of the weld line (scale bar: 5 mm). In order to validate the observed results, a high resolution tomographic scan was performed around the centre of the tensile sample where the weld line is located. The location of the investigated tomographic slices are shown in (e). In the coronal slice (f) the asymmetry of the weld line which is observed in the degree of anisotropy image (c) can be justified (scale bar: 2.7 mm). The zoom-ins (scale bar: \(400\ \upmu {\rm{m}}\)) highlight areas of low and high fibre alignment which correlate well with similar areas in the degree of anisotropy image marked by blue and green squares, respectively. The sagittal slices (g) show the difference between the weld line affected and non-areas of the sample as the fibre orientation changes from out of plane to in plane (scale bar: 1  \({\rm{mm}}\))
