Example Embodiment
[0032] The present invention will be further described in detail below through the accompanying drawings of the specification and specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.
[0033] Such as Figure 1-2 In the shown GIS end flange and cylindrical fillet weld ultrasonic phased array evaluation device, the scanning frame 6 is provided with two symmetrical positioning posts, and the wedge 5 is provided with two Two positioning holes are arranged symmetrically, and the connection between the wedge block 5 and the scanning frame 6 is realized through the cooperation of the positioning hole and the positioning column. The encoder 7 is connected with the pin hole on the rear side of the scanning frame through the pin shaft on the front. The encoder 7 is a wheel-type incremental rotary encoder. The encoder 7 is connected to the ultrasonic phased array detector 9 th...
