As we mentioned above, shot blasting is a surface conditioning process. Small metal ball, called the shots, are used to induced the residual stress on the surface of the work piece. The process is described as a cold rolling process. Plastic deformation of a work piece is achieved by the help of compressive force applied by the high velocity shots.
