| Abstract: | The principle and feature of time-of-flight-diffraction （TOFD） was introduced. The method was used to inspect an in-service hydrogenation reactor. The inspection result was verified by ultrasonic wave and proved that TOFD is effective method to find out a crack flaw within the joint of welding seam. The flaw was removed for safety. |
