Problems solved by technology

For steel plates that cannot be 100% full-scale flaw detection, in order to ensure the quality of welding or other processes, users have to take measures such as non-destructive cutting again, which virtually increases the cost of the process

Embodiment 1

[0038] according to Figure 3 to Figure 8 A full-scale non-blind zone flaw detection device for medium and thick plates is shown, including a conveying roller table 1, two rows of ultrasonic probes 5, a left water-sealed box 3, a right water-sealed box 4, and a transverse water-sealed box 6. The ultrasonic probes 5 are set Above the conveying roller table 1, two rows of ultrasonic probes 5 are arranged in a staggered manner, and a horizontal water-sealed box 6 is provided below each row of ultrasonic probes 5. There are three water outlet slits on the surface, and the water outlet slits are relatively small. The two ends of the two horizontal water seal boxes 6 are respectively provided with a left water seal box 3 and a right water seal box 4. The left water seal box 3 and the right water seal box The box 4 is respectively externally connected to the coupling water source of the flaw detector. The horizontal water sealing box 6, the left water sealing box 3, and the right wat...

Embodiment 2

[0053] A method for static flaw detection using the above-mentioned full-size non-blind spot flaw detection device for medium and thick plates: comprising the following steps: using the above-mentioned structures of the horizontal water seal box 6, the left water seal box 3, and the right water seal box 4, the two stationary steel plates 2 The side, head, and tail are surrounded, which also plays the role of simulating the expansion steel plate 2 with a water belt, and then adopts a mobile ultrasonic probe 5 for detection without blind spots.

Abstract

The invention relates to a moderate-thickness plate full-dimensional non-blind area flaw detection device. The device comprises a transfer roller way, two lines of ultrasound probes, a left water sealing box, a right water sealing box, and a cross water sealing box; the ultrasound probes are arranged at the upper part of the transfer roller way, and distributed in a staggering manner; the lower part of every line of the ultrasound probe is provided with one cross water sealing box; both ends of the two cross water sealing boxes are respectively provided with a left water sealing box and a right water sealing box; the left water sealing box and the right water sealing box are respectively and externally connected with a flaw detector coupling water sources; the upper parts of the cross water sealing box, the left water sealing box, and the right water sealing box are provided with nozzles; the cross water sealing box, the left water sealing box, and the right water sealing box are installed on a rack together. The flaw detection device has the beneficial effect that for the guidance of water strips at surrounding of the steel plate, the ultrasound probe can normally emit the conducting ultrasound wave, and the detection can smoothly transit to the inner part of the steel plate; thus the 10 mm side part which cannot be detected in the past has performed with flaw detection; finally, the full-dimensional non-blind area flaw detection is realized.

Description

technical field [0001] The invention relates to the field of non-destructive testing, in particular to a full-scale non-blind zone flaw detection device and method for medium and thick plates. Background technique [0002] Medium and thick steel plates are widely used in national economic construction. According to standard regulations or user requirements, ultrasonic flaw detection is required for special-purpose steel plates such as boiler and pressure vessel plates, medium-thick steel plates for bridges, buildings, and pipelines. [0003] At present, most ultrasonic flaw detectors use pulse reflection flaw detectors. It is mainly composed of pulse emission, recovery probe and subsequent processing system. The probes are made of piezoelectric crystals. Piezoelectric crystals generate ultrasonic waves under the excitation of high-frequency pulse waves generated by electronic pulses. The ultrasonic wave passes through the water coupling vertically and enters the steel pl...
