Title
Welding - Use of time-of-flight diffraction technique (TOFD) for examination of welds
Svejsning - Brug af TOFD-teknik til prøvning af svejsninger
Dansk Standard
Publication Date:

Scope:
This document specifies the application of the time-of-flight diffraction (TOFD) technique for the semi-, or fully-automated ultrasonic testing of fusion welded joints in metallic materials equal to and above 6 mm thickness. It is primarily intended for use on full penetration welded joints of simple geometry in plates, pipes and vessels, where both the weld and parent material are low alloyed carbon steel. Where specified and appropriate, TOFD may also be used on other types of materials that exhibit low ultrasonic attenuation (especially that due to scatter).
