Brothers Inspection offering the following NDT (Non Destructive Testing) Services:- Positive Material Identification(PMI), Ultrasonic Testing, Radiograpy Testing, Magnetic Particle Testing , Dye Penetrant Testing and many more of Non Destructive testing available from Us. Although we support our client projects with many more NDT disciplines (see our list under Specialist manpower) these are the main NDT services offered independently on a project basis.
This method is based on the same principle as medical radiography in a hospital. A piece of
radiographic film is placed on the remote side of the material under inspection and radiation is
then transmitted through from one side of the material to the remote side where the
radiographic film is placed.
The radiographic film detects the radiation and measures the various quantities of radiation
received over the entire surface of the film. This film is then processed under dark room
conditions and the various degrees of radiation received by the film are imaged by the display
of different degrees of black and white, this is termed the film density and is viewed on a special
light emitting device. Discontinuities in the material affect the amount of radiation being received
by the film through that particular plane of the material.
Qualified inspectors can interpret the resultant images and record the location and type of
defect present in the material. Radiography can be used on most materials and product forms,
e.g. welds, castings, composites etc.
Radiographic testing provides a permanent record in the form of a radiograph and provides a
highly sensitive image of the internal structure of the material. Radiography is split into two main
categories;
-Radiographic Testing
-Radiographic Interpretation
