Descrizione Non-Destructive Testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of a material, component, structure or system for characteristic differences or welding defects and discontinuities without causing damage to the original part.
Contractors involved in the construction of oil & gas facilities (both upstream and downstream) make available NDT operators who are responsible for visually identifying any indication, i.e., the response or evidence of any anomaly/defects from a non-destructive examination on piping welds from the reading of x-ray plates/films NDT images. In this light, this thesis aims at developing a computer vision model for piping weld indications identification relying on artificial intelligence which automatically detects and diagnoses possible indications from x-ray plates/films NDT images.
This intelligent system should be able to perform the following tasks:
1. Quality image check: checking of required Image Quality Indicators (IQIs)
2. Detection: detection of the presence of any indication (anomaly/defect);
3. Characterization: diagnosing the type of the indication (if any);
4. Size assessment: assessing the size of the indication (if any);
5. Compliance check: verifying if the size of the indication is greater than some fixed
default thresholds.
