As a Surface Finishing Process:
- Removing surface contamination
- Creating a specific finish on a desired surface
As a Surface Preparation Process:
- Roughening surfaces for the application of paint
- Removing surface irregularities
As a Surface Modification Process, It Increases Compressive Stresses on the Surface:
- Providing increased fatigue life
- Decreasing susceptibility to stress corrosion
- Correcting distortion
- Forming structural steel and plate.
