orientation<\/p>\n\n\n\n<p><u>Abstract<\/u>: The results of rotating eddy current testing can be regarded as the results superposed by the uniform eddy current testing in orthogonal directions. However, in the case of the directional nondestructive testing problem, such as welds detection, only the results from the induced current that is perpendicular to the crack have the greatest sensitivity. In contrast, the results from other induced current orientations may contain a large amount of noise generated by welds. In this work, a brief method is proposed to transform the results of rotating eddy current testing into the results of uniform eddy current testing at the desired eddy current orientation. The experiments indicate that both the signal distribution and the signal amplitude of the transformed results well match the results of uniform eddy current testing. Moreover, an application of the proposed method in welds detection is conducted. The results reveal that the welds noise significantly decreased and that the indication of slits can be obviously identified. The results validate that the proposed method can improve the detection ability and expand the application of the rotating eddy current testing technique.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Transformation of rotating eddy current testing signal at desired eddy current o &#8230; <\/p>\n","protected":false},"author":1,"featured_media":6532,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2,8,183],"tags":[143],"class_list":["post-7681","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-achievement","category-journal","category-ndte-int","tag-143"],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/web.tohoku.ac.jp\/yusa\/wp-content\/uploads\/2021\/01\/logo_ndte_2021.png?fit=200%2C200&ssl=1","_links":{"self":[{"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts\/7681","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/comments?post=7681"}],"version-history":[{"count":9,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts\/7681\/revisions"}],"predecessor-version":[{"id":7702,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts\/7681\/revisions\/7702"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/media\/6532"}],"wp:attachment":[{"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/media?parent=7681"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/categories?post=7681"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/tags?post=7681"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
