| Abstract: | The design and manufacturing processes of the narrow-pulse probe, matching between the probe and the instrument as well as design of the shape and size of the wedge were studied. A broadband longitudinal wave angle probe is obtained, whicah has high sensitivity, high resolution, high S/N ratio and accuracy of flaw-location. It is suitable for ulirasonic inspection of austenitic stainless steel welds. |
