Multiframe Ultrasonic TOFD Weld Inspection Imaging Based on Wavelet Transform and Image Registration
TOFD (time of flight diffraction) is a kind of weld defect detection technology by using ultrasonic diffraction wave signal. Because the diffraction intensity is far less than ultrasonic echo wave intensity, thus, the noise contained in TOFD signal is fairly large, and the formed image is not clear...
