Non submerged testing gives a lot of possibilities for false indications while the submerged testing is a pretty complicated and time consuming process.<\/p>\n<p>The new TC system offers a semi-submerged system where only the surface tested is submerged. This gives excellent stability during testing excluding most common problems in connection with non-submerged testing.\u00a0 In addition this system gives several technical advantages.<\/p>\n<p>TC has almost excluded water spill as the system has a closed water loop. Water is pumped into the inner water tray where multiple ultrasonic sensor heads are placed. Water will then flow to the outer chamber where it is collected directly and returned to the water tank.<\/p>\n\n\t\t<style type=\"text\/css\">\n\t\t\t#gallery-1 {\n\t\t\t\tmargin: auto;\n\t\t\t}\n\t\t\t#gallery-1 .gallery-item {\n\t\t\t\tfloat: left;\n\t\t\t\tmargin-top: 10px;\n\t\t\t\ttext-align: center;\n\t\t\t\twidth: 25%;\n\t\t\t}\n\t\t\t#gallery-1 img {\n\t\t\t\tborder: 2px solid #cfcfcf;\n\t\t\t}\n\t\t\t#gallery-1 .gallery-caption {\n\t\t\t\tmargin-left: 0;\n\t\t\t}\n\t\t\t\/* see gallery_shortcode() in wp-includes\/media.php *\/\n\t\t<\/style>\n\t\t<div id='gallery-1' class='gallery galleryid-374 gallery-columns-4 gallery-size-medium'><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon portrait'>\n\t\t\t\t<a href='https:\/\/tce.no\/wp-content\/uploads\/2016\/06\/tce1.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"640\" src=\"https:\/\/tce.no\/wp-content\/uploads\/2016\/06\/tce1-700x640.jpg\" class=\"attachment-medium size-medium\" alt=\"\" \/><\/a>\n\t\t\t<\/dt><\/dl><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/tce.no\/wp-content\/uploads\/2016\/06\/tce2.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"640\" src=\"https:\/\/tce.no\/wp-content\/uploads\/2016\/06\/tce2-720x640.jpg\" class=\"attachment-medium size-medium\" alt=\"\" \/><\/a>\n\t\t\t<\/dt><\/dl><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/tce.no\/wp-content\/uploads\/2016\/06\/tce3.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"640\" src=\"https:\/\/tce.no\/wp-content\/uploads\/2016\/06\/tce3-720x640.jpg\" class=\"attachment-medium size-medium\" alt=\"\" \/><\/a>\n\t\t\t<\/dt><\/dl><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/tce.no\/wp-content\/uploads\/2016\/06\/tce4.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"640\" src=\"https:\/\/tce.no\/wp-content\/uploads\/2016\/06\/tce4-720x640.jpg\" class=\"attachment-medium size-medium\" alt=\"\" \/><\/a>\n\t\t\t<\/dt><\/dl><br style=\"clear: both\" \/>\n\t\t<\/div>\n\n<p>In traditional non submerged systems the ultrasonic sensor head have to be placed very close to the billet surface.\u00a0 The surface and the outer part of the billet volume will then have to be excluded from testing and then tested separately.\u00a0 For the TC system the ultrasonic sensor heads are placed in a specific distance from the billet surface.\u00a0 A scanning can then be done of the full volume.\u00a0 Only the surface will have to be excluded as this can include damages from casting or handling.\u00a0 This method also allows us to use sensor heads with larger scanning surface which will cover a higher volume of the billet during scanning.<\/p>\n<p>100 % scanning of billets is a pretty time consuming operation.\u00a0 A TC system with 2 x 16 ultrasonic probes can scan a billet in 95 sec., still being within the demands given in the standard for this operation.\u00a0 Scanning speed may be increased by using additional sensor units.<\/p>\n<p>Calibration of this system is also quite simplified compared with other systems. Calibration can be performed automatic by start of a new scanning cycle.<\/p>\n<p>The system can also be supplied for centre crack testing \u2013 then with only two probes and a much higher scanning speed.\u00a0 Or it can be supplied as combined system performing centre crack test or 100 % test according to requirements.<\/p>\n<div style=\"width: 1200px;\" class=\"wp-video\"><!--[if lt IE 9]><script>document.createElement('video');<\/script><![endif]-->\n<video class=\"wp-video-shortcode\" id=\"video-374-1\" width=\"1200\" height=\"506\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/tce.no\/wp-content\/uploads\/2016\/07\/INFACE-1920x810.mp4?_=1\" \/><a href=\"https:\/\/tce.no\/wp-content\/uploads\/2016\/07\/INFACE-1920x810.mp4\">https:\/\/tce.no\/wp-content\/uploads\/2016\/07\/INFACE-1920x810.mp4<\/a><\/video><\/div>\n","protected":false},"excerpt":{"rendered":"<p>TC Engineering AS has recently upgraded its product range with a new system for 100 % ultrasonic testing of extrusion billets.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[19],"tags":[],"_links":{"self":[{"href":"https:\/\/tce.no\/wp-json\/wp\/v2\/posts\/374"}],"collection":[{"href":"https:\/\/tce.no\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tce.no\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tce.no\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tce.no\/wp-json\/wp\/v2\/comments?post=374"}],"version-history":[{"count":7,"href":"https:\/\/tce.no\/wp-json\/wp\/v2\/posts\/374\/revisions"}],"predecessor-version":[{"id":631,"href":"https:\/\/tce.no\/wp-json\/wp\/v2\/posts\/374\/revisions\/631"}],"wp:attachment":[{"href":"https:\/\/tce.no\/wp-json\/wp\/v2\/media?parent=374"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tce.no\/wp-json\/wp\/v2\/categories?post=374"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tce.no\/wp-json\/wp\/v2\/tags?post=374"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
