بیشترIntroduction to Shot Peening Shot peening is a cold working process in which the surface of a part is bombarded with small spherical media called shot. Each piece of shot striking the metal acts as a tiny peening hammer, imparting a small indentation or dimple on the surface. In order for the dimple to be created, the surface layer of the metal must yield in tension.
