RADIOGRAPHIC INTERPRETATION

Description

Radiography film interpretation is the process of examining radiographic images to detect and evaluate welding defects. Welding defects can be internal or external, and can affect the strength and integrity of the welded joint.

Radiographs are produced by using X-ray or gamma radiation to penetrate the material being tested and create an image which can be interpreted by a trained professional in accordance with relevant technical specifications and/or customer requirements.

Advantages

1. Detection of internal defects for thick materials (e.g., pipelines).
2. Minimal or no part preparation is required.
3. One of the major advantages of RT is its documentation capability, and RT provides images of the object under inspection.

Limitation

1. A high degree of skill and experience is required for exposure and interpretation.
2. Ineffective for planar defects and surface defects.
