Peening

Shot peening is undertaken using an air blast
system or centrifugal blast wheels. The air blast
system uses high-pressure air for firing the
shots through a nozzle at the workplace. A
centrifugal blast wheel uses a high-speed paddle
wheel that peening using centrifugal force.

Why is Shot Peening Used?

• The main benefit of shot peening is to expand the
  service life of an element by creating an induced
  compressive stress layer for increasing
  resistance to fatigue though also helping to
  resist the development and propagation of cracks.
  The creation of compression stresses helps
  prevent the propagation of cracks through the
  material.

Difference between Shot Peening and Shot Blasting

• Shot blasting is an industrial process that is
  used for modifying a components surface. The
  process of sand blasting works on the principle
  of abrasion. A stream of abrasive particles is
  propelled under high pressure onto the plane of
  an element for smoothing a rough surface,
  roughening a smooth surface, shaping a surface,
  or removing surface contaminants

7
Shot blasting is also used for preparing a
surface for subsequent operation, such as the
painting of welds. Shot peeing is actually
different from shot blasting in that it is used
for removing surface material properties through
the addition of compressive stresses.

Advantage of Shot Peening

• The main advantage of shot peening include
  improved strength and fatigue resistance, also
  when handing out complex geometric parts. This
  process is well-known and also relatively
  inexpensive. It has also substantial research and
  quality controls for ensuring its effectiveness.
