Abstract

Long-distance and large-area damage detection is always regarded as a difficulty in practical engineering application, especially for traditional nondestructive testing (NDT) methods. However, since the advent of ultrasonic guided wave (UGW), it becomes hopeful because of its property of propagating along the waveguide like a long-distance pipeline. In this study, together with pure torsional mode T(0,1) excited by magnetostriction (Ms) material, the annular sensor placement, sinusoidal signal modulated by Hanning window and characteristic frequency range considering attenuation are all selected to increase the propagation distance and improve signal to noise ratio (SNR). By various optimization designs, the damage detection distance in a steel pipeline can reach up to 100 m with strong reflection echoes, which is significant to fast perform damage detection of large structures and infrastructures like bridge deck, fan blade, gas pipeline, etc.
