Meaning and Definition
A surface preparation process that uses high-velocity abrasive particles (shot) to clean, strengthen (peen), or texture a material, typically metal.
The industrial technique of propelling small spherical media (steel shot, glass beads, etc.) at a surface to remove scale, rust, paint, or contaminants, or to improve fatigue resistance via shot peening.
Dialectal Variation
British vs American Usage
Differences
The term is standard in both varieties, but American English may more frequently use 'abrasive blasting' or specify the media (e.g., 'wheel blasting', 'shot peening'). The hyphen is common in UK usage.
Connotations
Industrial, manufacturing, construction, and restoration contexts. Implies a robust, heavy-duty cleaning/preparation method.
Frequency
Higher frequency in technical manuals, engineering, and industrial maintenance texts than in general language.

Common Mistakes When Using “shot-blasting”

- Omitting the hyphen.
- Confusing 'shot-blasting' (cleaning) with 'shot peening' (strengthening).
FAQ
Frequently Asked Questions
No. While both are abrasive blasting techniques, sandblasting typically uses silica sand or other angular abrasives to cut and etch a surface. Shot-blasting uses spherical media (steel shot, glass beads) which cleans and can peen (compress) the surface, improving fatigue resistance.
Shot peening is a subset of shot-blasting where the primary objective is not cleaning, but mechanically working the surface with shot to create compressive stresses, which improves resistance to fatigue and stress corrosion cracking.
Automotive (engine parts, chassis), aerospace (turbine components), shipbuilding (hulls), construction (structural steel), foundries (casting cleanup), and manufacturing of heavy machinery.
Steel shot (various hardnesses), cut wire shot, stainless steel shot, glass beads (for a brighter, smoother finish), and ceramic beads.
A surface preparation process that uses high-velocity abrasive particles (shot) to clean, strengthen (peen), or texture a material, typically metal.
