Abstract: The guided wave technology is usually applied to detect defects in
the regular zone. In this paper, the guided wave technology is applied to
detect the flaw in the transition zone of sucker rods where is an irregular
zone. A piecewise model is established by making a difference between the down
step flaw and the up step flaw. The experiments are carried on a sucker rod
sample with the artificial notch flaws in the transition zone using
magnetostrictive guided waves. The experimental results agree well with the
theoretical predictions. The result indicates that the guided wave technology
could be applied to inspect some special irregular structures.
