RADIOGRAPHIC TESTING

Training Duration 80 hours (8 days)

Basic Principle – Radiographic Testing (RT)

Radiographic testing can be used to detect internal defects in castings, welds or forgings by exposure the construction to x-ray or gamma ray radiation. Defects are detected by differences in radiation absorption in the material as seen on a shadow graph displayed on photographic film or a fluorescent screen.

Description

This course provides detailed theoretical and practical information on all the commonly encountered Radiographic Testing (RT) techniques. Candidates will have the opportunity to use the various techniques on welds, castings and wrought products.
This course meets the training hour requirements as specified by the American Society of Non-Destructive Testing (ASNT) Recommended Practice documents SNT-TC-1A.
