The invention relates to a shot blasting check method for surface defects of blades. Turbine blades processed by the method can clearly show various surface defects easily generated in materials during processes, and specifically the method can check that the defects are the liquation of the materials, various processing burns, hardening and the like in the processes. The method is characterized in that the method for surface shot blasting achieves the show of the surface defects of the blades.
