High Sensitivity Ultrasonic NDT Technique for Detecting Creep Damage at the Early Stage In Power Plant Steels
• The conducted research demonstrated that early stage creep damage can be identified.
• The signal processing including filtering, alignment of signals, correction of front wall reflection and extraction of the noise.
• The early stages creep damage causes only minor, however, a significant increase of the structural noise in the heat affected zone.
• The presented technique is appropriate to be used for detecting different levels of structural noise.
