摘要
Abstract
Some defects easily appear in weld of HFW pipe, such as incomplete fusion (cold welding), crack, inclusion etc. The above defects are mainly area type defects along weld extension. These defects can be detected by creeping wave testing according to defects characteristics of thin-walled high-frequency electric resistance welded pipe. In this article, it expatiated the detection principle, features and process method of the creeping wave testing method, designed the creeping wave testing special probe and the reference blocks. The practical detection results showed that the creeping wave testing is a new type of high efficient detection method, and the creeping wave detection technology feasibility in thin-walled high-frequency electric resistance welded pipe was proved.关键词
