Radiography is employed as one of the most efficient and effective inspection techniques. Industrial radiography is the use of ionizing radiation to view objects in a way that cannot be seen otherwise. It is not to be confused with the use of ionizing radiation to change or modify objects.
Radiography’s purpose is strictly viewing. Industrial radiography has grown out of engineering, and is a major element of nondestructive testing. It is a method of inspecting materials for hidden flaws. Radiography is used principally to reveal weld defects and irregularities, but can also be used to locate pitting, corrosion, blockages, product build up and casting defects. It can be used on a variety of materials from plastic to metal and metal alloys castings, forgings and food products.
It can be used in a fabrication environment to establish the weld quality levels being achieved are as per Customer and acceptance criteria requirements. It can be used to establish where weld failure is likely to occur, or the reason for weld failure.
In EIS we have used X Radiography to find a staple in a 40 kg bag of powder product!
EIS carry out X-Radiography using Andrex Smart Directional and Panoramic equipment with a KV Range up to 300Kv.
We use ᵞ (Gamma) radiography using Selenium 75 (Sel75) or Iridium 192 (Ir 192) in the newly designed Viking Projectors. (see image above) All EIS radiographers are approved to EN 473 Level 2 requirements.
Radiography Inspection is a versatile technique which can be adapted to be used both in the laboratory or on site, and on parts both large and small.
- Safety issues result in limiting the application:
- Not ideal for in service inspection
- Not able to test lines working at extreme temperatures.
