| Abstract: | The ultrasonic wave probe for small diameter thin wall pipe mentioned in this article has the characteristics of enough sensibility,narrow starting wave(< 2.5 mm),short edge(≤5 mm),high resolution,less clutter and less surface wave component. This probe is suitable for ultrasonic quantitative inspection of hoop butt weld in small diameter thin wall pipe.After trial application and verification,it has been concluded that the probe conforms to practical requirements,and by using it good effect was obtained and the problems existed in substitution of ultrasonic wave inspection for radiology inspection have also been solved. |
