INDUSTRIAL RADIOGRAPHY

This course has been developed for those who have received little or no formal radiographic training. This syllabus has been designed to cover all major aspects of theory and practical radiography for the examination of welds. The syllabus includes hands-on experience relating to the use of X and gamma radiographic techniques.

This method consists of radiographic film being placed under a sample. The sample is then exposed to radiation, the radiation passes through the sample and exposes the film. Discontinuities in the sample affect the exposure of the film. Most materials can be tested by radiographic inspection, e.g. welds, castings, composites etc. Radiographic testing provides a permanent record and provides a high sensitivity of testing.

This course is for NDT personnel wishing to carry out radiography testing, this course incorporates interpretation of the radiograph in addition to the techniques used to create the radiography.
