Whilst conventional ultrasonics uses shear/transverse waves as the primary mode of detection, TOFD uses longitudinal waves as the primary detection mode. Ultrasonic sensors are placed on each side of the weld. One sensor transmits the ultrasonic beam into the material and the other sensor receives both reflected and diffracted ultrasound from anomalies and geometric reflectors.

Using ultrasonic beam spread, TOFD provides a wide area of coverage for anomaly detection in the material being tested. When the beam impinges on a flaw tip, it is diffracted in all directions. Measurement of the time of flight of this diffracted beam enables accurate and reliable flaw detection and sizing. This is the case even if the crack is not oriented to the intial beam direction. During typical TOFD inspections, A-scans are collected and used to create B-scan (side view) images of the weld. Post acquisition analysis is done using software to measure the flaw length and through-wall height.[/vc_column_text][/vc_column][vc_column width=”1/2″][grve_single_image image=”2885″][/vc_column][/vc_row][vc_row bg_type=”image” bg_image=”2337″ bg_image_type=”parallax” color_overlay=”dark” opacity_overlay=”80″ header_feature=”yes”][vc_column width=”1/3″ css=”.vc_custom_1571341722073{padding-top: 50px !important;padding-bottom: 50px !important;}”][vc_custom_heading text=”OUR VISION” font_container=”tag:h3|text_align:center|color:%23dd3333″ use_theme_fonts=”yes”][vc_column_text css=”.vc_custom_1571342317530{padding-bottom: 50px !important;}”]Our vision is to be a world-class Company renown for Quality of products, Safety and reliability of Services.[/vc_column_text][/vc_column][vc_column width=”1/3″ css=”.vc_custom_1571342068032{padding-top: 50px !important;padding-bottom: 50px !important;}”][vc_custom_heading text=”OUR MISSION” font_container=”tag:h3|text_align:center|color:%23dd3333″ use_theme_fonts=”yes”][vc_column_text css=”.vc_custom_1571342360745{padding-bottom: 50px !important;}”]Our mission is to eliminate work repetition by “doing it right the first time” and thus operate in a manner that is most competitive in the industry.[/vc_column_text][/vc_column][vc_column width=”1/3″ css=”.vc_custom_1571341745145{padding-top: 50px !important;padding-bottom: 50px !important;}”][vc_custom_heading text=”OUR STRATEGY” font_container=”tag:h3|text_align:center|color:%23dd3333″ use_theme_fonts=”yes”][vc_column_text css=”.vc_custom_1571342401607{padding-bottom: 50px !important;}”]To accomplish our mission, all CIS employees shall be well trained to work as a team and maintain CIS corporate ideas.[/vc_column_text][/vc_column][/vc_row]
