In this study, in order to effect of process parameters on residual stress distribution, cantilever test and numerical analysis was carried out. These results shown the scan pattern is effect on residual stress distribution and deformation. The hatch size was important parameter because that become larger, the deformation and residual stress reduced. And, in numerical analysis result showed shorter hatch size occurs big residual stress. It is thought that the hatch was shrinked like one bead because as hatch size be shorter, laser moved fast and make a round trip.
