Laser shock peening (LSP) is a novel surface modified technique. In practical applications, due to the diameter of laser beam smaller than 20 mm, the overlapping LSP technology needs to process workpiece surface with large area. The residual stress fields induced by laser spots in different center distances are discussed with finite element methods and experiments. The influences of overlapping rate on the distributions of residual stress are investigated. The characteristics of residual stress distributions induced by different shocking sequences are also analyzed. The results show that the center distances of laser spots have significant influences on the residual stress of region between two laser spots. With the center distances of two laser spots decreasing, the residual stress fields at the region between two laser spots turn from tensile residual stress into compressive residual stress. The magnitude of compressive residual stress is increased with the increment of laser spot overlapping rate, and the distributions of residual stress generated by larger overlapping rate are more uniform. The multiple shocking sequence of mid-left-right can induce a large and uniform compressive residual stress field .
