The invention relates to the field of laser peening orthopedic, in particular to a laser peening orthopedic method aiming at a thin-walled through hole piece. Correcting the deformed part into a qualified shape and introducing residual compressive stress in the corrected area can improve the service life of the part. After laser shock correction, the sheet metal recovered from concave-convex state to flat state, and the flatness was less than 0.005mm, and the ideal straightening effect was obtained. The amount of sheet metal shape correction increases with the increase of the depth and magnitude of residual stress, that is, by controlling the variation of laser power density, the amount of shape correction can be adjusted to achieve the purpose of accurate shape correction.
