    The aim of this paper is to describe the effects of laser welding on the real structure and residual stresses of construct steel S355 in comparison with classical arc welding. Therefore, results out line the capability of the advanced laser welding for joining thick sheets of steel using neutron diffraction and X-ray diffraction. This paper describes the effects of welding on the state of residual stresses and the real crystallographic structure (phase composition, crystal-lite size, microstrain) on cross-section of welds. Furthermore, the results of neutron diffraction verify previous as sumptions of residual stresses redistribution as a result of the surface preparation for determination by X-ray diffraction in two directions on the cross-section of the welds.
