Abstract:
The strain and phase distribution in a dissimilar friction stir weld of AA6082-T6 to AA2024-T3 is investigated
non-destructively. The measurements are performed using a novel depth resolved strain and phase mapping technique. The technique is based on the use of a focussed high energy synchrotron beam, a novel spiral slit
system, and an area detector system. Through thickness measurements of the residual strain along the weld centre show strong variations with changes of sign. The strain scans across the weld exhibit a strong asymmetry
in particular for the longitudinal strain component. A depth resolved strain mapping across the weld shows for the dominant longitudinal strain component variations in depth, especially on the AA6082 side
of the weld. Results from the strain measurements are related to the depth resolved map of the material distribution in the weld zone.
