– Field metallographic procedures are performed “on location” or in the “field” on components that are too large to bring to the metallographic laboratory.
– Generally, these components are still being used in service or must be returned to service and cannot be destructively sectioned or physically altered.
– Field metallography is also called in situ metallography, and it is sometimes called nondestructive metallography.
The major application areas are
- Power plants,
- Heavy Engineering Components,
- petroleum and natural gas pipelines,
- welding quality inspection for metal constructions
- Onsite analysis of changes in metallography over time
- Non Destructive metallography of critical components…etc.
– In situ metallographic work must be performed on-site without damaging the components. This means that portable metallographic instruments for grinding, polishing, and etching procedures are required.
