It helps relieve stress and hardens the surface of the metal.
Actually peening introduces a compressive stress in the surface, this can prevent fatigue in high stress areas.

Usually special equipment is needed.

There are essientially two types of peening machines; centrifugal and pneumatic. The basic principles of the pneumatic machine is similar to blasters, but the actual machine is much more complicated.
