Intelligent defect recognition for pipeline girth welds based on automated ultrasonic testing

Automated ultrasonic testing (AUT) is an effective technique for non-destructive evaluation (NDE) of pipeline girth welds. In this paper, a deep learning method is proposed for automatic identification of defects in such welds. Criteria for defect classification in the girth weld are extracted from AUT mapping. A deep...
