      abstract     = {Synchrotron radiation was used for fine probing the
                      different regions of a laser welded NiTi
                      joint.Measurementswere taken at 0.2mmintervals, starting in
                      the non-thermal affected material, through the heat affected
                      zone, thefusion zone and again across the heat affected zone
                      finishing in the basematerial. Along the longitudinal
                      directionthe residual stresses were found to be always
                      tensile in the heat affected and fusion zones; along the
                      transversaldirection, an inversion of the stress stateswas
                      found. Themagnitude of the residual stresseswas found to
                      bemoresignificant in the transversal direction due to
                      constraints imposed during welding. The heat introduced
                      duringwelding has a stress relief effect on the cold-rolled
                      base material, although it does not promote any
                      solid-statetransformation. The effect of the heat input on
                      the residual stress pattern and magnitude was identified and
                      itwas seen that high heat input leads to a higher magnitude
                      of the residual stresses in the weld and the stress
                      reliefeffect is observed over a larger extension from the
                      weld centerline. This paper presents the first
                      experimentalstudy on the determination of residual stresses
                      on laser welded NiTi shape memory alloys.},
