Resumen:
Similar and dissimilar friction stir welds of AA5083 and AA6061 were producedmodifying the location of the materials in the joint (advancing or retreating side) and travel speed (73 and 206 mm/min). Longitudinal and transverse residual stresses were evaluated by X-ray diffraction technique on the mid-length of each welded sample, in the transverse direction to the weld on a 42 mm distance. Unstrained lattice spacing (d0) and full width at half maximum (FWHM) were also measured. A peak of tension stress at the edge of stirred zone was detected, describing an ?M? like profile, which were more asymmetrical for dissimilar joints. Variations in d0 and FWHM were also observed through the welded joint, which were related to microestructural changes
