Abstract: Ultrasoni guided w ave have some advant ages in dete ting orrosion of inservi e pipelines. It is
introdu ed in this paper about hara terist i waveform of ultrasoni guided w ave dete t ion of pipeline orrosion,
whi h is onvenient for professional to identify smaller defe t s. By a large number of pra ti e in ultrasoni guided
wave dete tion, some experien es in identify ing orrosion of ultrasoni guided w ave dete tion were summarized,
whi h have been validated in pra ti e, de reasing rate of faulse alls.
Keywords:U ltrasoni guided w ave testing; Chara teristi of guided w ave for orrosion; Ident ifying rule
