Description

Technical Field

[0001] The present application relates to the technical field of penstock bend weld detection technology, and in particular to a phased array detection method and device for water diversion penstock bend welds with gradient angles. Background Art

[0002] Among the key facilities in hydropower plants, the diversion penstock carries the crucial task of delivering high-pressure water to the turbines. Exposure to high head, pulsating loads, and complex environmental erosion for extended periods of time, the quality of its welds directly impacts the safe operation of the power station. As hydropower units develop toward higher heads and larger diameters, the inner and outer curvature radii of the bend differ due to terrain adaptation requirements. This necessitates the widespread adoption of a multi-section steel plate splicing design, resulting in a transitional weld with a gradient angle. These welds are geometrically complex and exhibit significant stress concentration. Under water hammer or fatigue loads, they are prone to cracks, lack of fusion, and other defects, making them a weak link in structural safety.

[0003] According to relevant regulations, penstocks must undergo safety inspections at regular intervals to promptly detect and address weld crack defects and eliminate equipment safety hazards. Conventional A-type pulse ultrasonic testing of bend welds in water diversion penstocks is currently used. However, this method has numerous limitations. Its single, fixed beam angle, manual operation mode, and defect amplitude display mode make it difficult to adapt to the diverse geometric shapes, complex grooves, and poor acoustic field accessibility of gradient-angle welds. Consequently, it is unable to achieve blind-spot detection of gradient-angle welds, and it is difficult to accurately distinguish defect reflection signals from inherent weld reflection signals.

[0004] Therefore, the weld detection method in the relevant technology is difficult to adapt to the complex geometric shapes and groove changes of gradient angle welds, resulting in the inability to achieve blind spot detection, reducing the accurate identification rate of internal defects in welds, increasing the risk of missed detection and misjudgment, and reducing the accuracy and reliability of weld detection, which urgently needs to be solved.

[0041] The following describes a phased array detection method and device for the gradient angle weld of a water diversion pressure steel pipe bend according to an embodiment of the present application with reference to the accompanying drawings. In view of the fact that the weld detection method in the related art mentioned in the background technology center is difficult to adapt to the complex geometric shape and groove changes of the gradient angle weld, resulting in the inability to achieve blind spot detection, reducing the accurate recognition rate of internal defects in the weld, and reducing the accuracy of weld detection, the present application provides a phased array detection method for the gradient angle weld of a water diversion pressure steel pipe bend. In this method, a target three-dimensional data model can be constructed based on the geometric parameters of the gradient angle weld of the pressure steel pipe bend section to determine at least one target phased array detection process parameter, so that a phased array probe and wedge can be prepared, and a tooling device can be designed.

This solves the problem that the weld detection method in the related technology is difficult to adapt to the complex geometric shapes and groove changes of gradient angle welds, resulting in the inability to achieve blind spot detection and reduced efficiency and accuracy in detecting internal defects in welds.

[0042] Specifically, Figure 1 A flow chart of a phased array detection method for gradient angle welds on bent water-diversion penstocks provided in an embodiment of the present application.

[0043] like Figure 1 As shown, the phased array detection method for the gradient angle weld of the water diversion penstock bend includes the following steps:

[0044] In step S101, a target three-dimensional data model is constructed based on multiple actual geometric parameters of the gradient angle weld of the target penstock bend section.

[0045] In the embodiment of the present application, the target gradient angle weld of the penstock bend section is the gradient angle weld currently undergoing geometric parameter measurement.

[0046] It can be understood that the embodiment of the present application can first accurately measure multiple geometric parameters in the gradient angle weld of the target pressure steel pipe bend section, and construct a target three-dimensional data model through the multiple geometric parameters obtained by precise measurement and three-dimensional modeling software, that is, construct an accurate data model of the gradient angle weld of the pressure steel pipe with different curvature bends, so as to accurately reflect the true shape of the weld and its surrounding structure, and effectively improve the feasibility of weld defect detection.

[0047] Among them, in one embodiment of the present application, a target three-dimensional data model is constructed based on multiple actual geometric parameters of the gradient angle weld of the target penstock bend section, including: collecting at least one geometric parameter of the angle, diameter, wall thickness, length, width, depth and shape of the gradient angle weld between the cylinder sections of the penstock bend section; importing at least one geometric parameter into the target three-dimensional modeling software to construct the target three-dimensional data model.

[0048] During the actual implementation process, the embodiment of the present application can use high-precision measurement tools, such as laser rangefinders, total stations, etc., to accurately measure at least one of the geometric parameters such as angle, diameter, wall thickness, length, width, depth, shape, etc. of the gradient angle weld between the sections of the bending section of the pressure steel pipe. Then, the measured geometric parameters can be imported into professional three-dimensional modeling software to construct a target three-dimensional data model. In addition, multiple geometric parameters can also be accurately measured to improve the comprehensiveness of the measurement data and improve the accuracy and reliability of the three-dimensional data model.

[0049] It should be noted that 3D modeling software includes but is not limited to SolidWorks and ANSYS; the constructed 3D data model includes the detailed geometric shape, size, groove form, angle and relationship with the surrounding structure of the weld.

[0050] In step S102, at least one target phased array detection process parameter is determined based on the target three-dimensional data model, and a phased array probe and a wedge that meet a first preset condition are prepared using the at least one target phased array detection process parameter, and a tooling device that meets a second preset condition is designed.

[0051] In the embodiment of the present application, the target phased array detection process parameters are optimal phased array detection process parameters.

[0052] It can be understood that the embodiment of the present application can select ultrasonic phased array simulation software based on the target three-dimensional data model, set the same environmental parameters as the actual detection, including the acoustic properties of the medium, such as sound velocity, density, etc. and the basic parameters of the probe, such as frequency, number of array elements, array element spacing, etc., and import the established three-dimensional data model into the simulation software, so that at least one target phased array detection process parameter, that is, the optimal phased array detection process parameter, can be determined according to the simulation results to form a set of theoretical simulation processes; secondly, the embodiment of the present application can also prepare a phased array probe and wedge that meet the first preset conditions based on the optimal phased array detection process parameters obtained by simulation, that is, the phased array probe and wedge with a specific frequency, array element arrangement and wedge angle in the following steps, and design a tooling device that meets the second preset conditions, that is, the tooling device adapted to the gradient angle welds of bends with different curvatures in the following steps, so as to achieve accurate adaptation and efficient and stable detection of welds of complex structures, significantly improving detection accuracy and adaptability.

[0053] In one embodiment of the present application, at least one target phased array detection process parameter is determined based on a target three-dimensional data model, including: importing the target three-dimensional data model into ultrasonic phased array simulation software to simulate the target detection process of the phased array probe on the gradient angle weld at different scanning positions and different incident angles; using the target detection process to obtain the sound beam propagation path and the reflected wave signal change, and determining at least one target phased array detection process parameter based on the sound beam propagation path and the reflected wave signal change.

[0054] As a possible implementation method, the embodiment of the present application can select ultrasonic phased array simulation software, set the same environmental parameters as the actual detection, including the acoustic properties of the medium and the basic parameters of the probe, import the established three-dimensional data model into the ultrasonic phased array simulation software, simulate the phased array probe to detect gradient angle welds at different positions and angles, and observe the changes in the sound beam propagation path and the reflected wave signal by adjusting the probe parameters to obtain simulation results. Then, the simulation results are analyzed to obtain the optimal phased array detection process parameters, such as the optimal probe frequency, the optimal array element combination method, the appropriate angle range, and other optimal phased array detection process parameters, to form a set of theoretical simulation processes, which can optimize the detection process parameters in advance and improve the scientificity and feasibility of the detection plan, thereby ensuring efficient and accurate detection of complex structure welds.

[0055] In the embodiment of the present application, ultrasonic phased array simulation software includes CIVA, Phased Array Toolkit, etc. The phased array detection process parameters optimized through simulation include probe frequency, number of array elements, angle range, sound beam focusing depth, etc.

[0056] Optionally, in one embodiment of the present application, at least one target phased array detection process parameter is used to prepare a phased array probe and a wedge that meet a first preset condition, and a tooling device that meets a second preset condition is designed, including: using at least one target phased array detection process parameter to set a phased array probe and a wedge that include a specific frequency, array element arrangement, and wedge angle; using at least one target phased array detection process parameter to design a tooling device for use in gradient angle welds of elbows with different curvatures, wherein the tooling device includes an adjustable fixed bracket, a probe moving track, and a coupling agent supply system.

[0057] In some embodiments, the embodiments of the present application can customize phased array probes and wedges with specific frequencies, array element arrangements, and wedge angles based on the optimal detection parameters simulated in the above steps. When customizing phased array probes and wedges with different parameters according to the simulation process, short-front probes are customized for positions where the probe movement distance is limited; for gradient-angle welds, wedges with a larger angle deflection range are customized to ensure that the sound beam can cover the entire weld area; for positions where the probe movement distance is limited, short-front probes are customized to meet the detection requirements of gradient-angle welds with different curvatures.

[0058] Therefore, the specially designed large-angle deflection wedge in the embodiment of the present application can ensure that the sound beam can achieve comprehensive scanning as the weld angle changes, significantly improving the comprehensiveness of the detection, basically eliminating the detection blind spots, and effectively avoiding the occurrence of missed defects.

[0059] Secondly, the embodiment of the present application can also customize a tooling device that is suitable for the gradient angle welds of bends with different curvatures, wherein the tooling device includes an adjustable fixed bracket, a probe moving track and a coupling agent supply system; the fixed bracket can be flexibly adjusted according to the shape and position of the gradient weld of the pressure steel pipe to ensure that the phased array probe can be stably attached to the weld surface; the probe moving track has high precision and stability, so that the probe can be accurately moved on the track to achieve a comprehensive scan of the weld; equipped with a coupling agent supply system to ensure a good coupling effect between the probe and the weld surface, improve the transmission efficiency of the ultrasonic signal, and the coupling agent supply system can automatically adjust the coupling agent supply amount according to the detection requirements, thereby achieving stable and efficient scanning of complex gradient angle welds and improving the reliability of the detection results of weld defects.

[0060] In step S103, a first target parameter in the phased array probe and the wedge, a second target parameter in the tooling device, and a third target parameter in the target phased array ultrasonic testing equipment are determined to establish a target phased array ultrasonic testing system. The target phased array ultrasonic testing system is optimized using a target gradient angle weld simulation test block. The optimized target phased array ultrasonic testing system is used to perform phased array testing on the gradient angle weld of the target penstock to obtain phased array testing results of the gradient angle weld of the water diversion penstock bend.

[0061] It can be understood that the embodiments of the present application can determine the first target parameters in the phased array probe and the wedge block, such as the probe frequency, the number and arrangement of array elements, the wedge block angle, etc.; the second target parameters in the tooling device, such as the probe scanning path planning, the bracket adjustment range, the coupling agent supply amount and the spray position and the encoder setting, etc.; the third target parameters in the target phased array ultrasonic detection equipment, such as the sector scanning angle range, the gain setting, the focusing law, etc., so as to establish a target phased array ultrasonic detection system, and use the gradient angle weld simulation test block in the following steps to optimize the target phased array ultrasonic detection system, so as to use the optimized target phased array ultrasonic detection system to perform phased array detection on the gradient angle weld of the target pressure steel pipe, and then obtain the phased array detection results of the gradient angle weld of the water diversion pressure steel pipe bend.

[0062] Among them, the probe encoder in the embodiment of the present application can record the probe position information; the phased array ultrasonic detection equipment can transmit and receive ultrasonic signals, and analyze and process the detection data. Therefore, the embodiment of the present application can be equipped with a tooling device and a probe encoder. When performing phased array detection on the gradient angle weld of the pressure steel pipe, it is ensured that the probe moves at a uniform speed along the moving track to ensure the comprehensiveness and accuracy of the detection.

[0063] In an embodiment of the present application, a material that is the same as or has similar acoustic properties to the base material of the pressure steel pipe can be selected to make simulation test blocks of gradient angle welds of bends with different curvatures, that is, target gradient angle weld simulation test blocks, to ensure that the acoustic properties of the simulation test blocks are similar to those of the actual pressure steel pipes; according to the types, shapes and sizes of defects that may appear in the actual welds, artificial reflectors of different shapes such as round, square, and crack-shaped, different depths, lengths, and different positions such as groove positions, weld roots, and different depths inside the welds are processed inside the simulation test blocks to simulate defects in actual welds, and clear markings are marked on the surface of the simulation test blocks, and information such as the position, shape, and size of the artificial reflectors are recorded in detail for subsequent comparison and analysis of the test results.

[0064] Optionally, in one embodiment of the present application, a target phased array ultrasonic detection system is optimized using a target gradient angle weld simulation test block, including: installing a phased array probe and a wedge on a tooling device, and connecting the tooling device to a target phased array ultrasonic detection device to detect a target reflector in the target gradient angle weld simulation test block to obtain a detection result; based on the detection result, adjusting the target parameters in the target phased array ultrasonic detection system to optimize the target phased array ultrasonic detection system.

[0065] During the actual implementation process, the embodiment of the present application can install the customized phased array probe and wedge block on the tooling device, and connect the phased array ultrasonic detection equipment to detect the reflector in the gradient angle weld simulation test block, adjust the detection equipment parameters, such as gain, TGC (Time Gain Compensation), etc., to make the detection signal reach the optimal state, record the reflector echo signal, including the amplitude, phase, propagation time and other information of the echo, and compare it with the simulation test block annotation information to verify the detection performance of the customized phased array probe and wedge block. According to the test results, the detection parameters are further optimized to ensure the accuracy and reliability of the test results, thereby optimizing the target phased array ultrasonic detection system, effectively improving the adaptability and sensitivity of the detection system, and ensuring its higher accuracy and stability in the detection of complex structure welds.

[0066] Furthermore, the embodiment of the present application can install the customized fixture in the optimized target phased array ultrasonic detection system at the gradient angle weld of the pressure steel pipe, use a fixed bracket to firmly fix the fixture on the surface of the pressure steel pipe, install a probe encoder on the probe moving track, and connect it to the phased array ultrasonic detection equipment, so that the detection equipment can record the position information of the probe in real time. Start the phased array ultrasonic detection equipment, and perform a comprehensive scan of the gradient angle weld of the pressure steel pipe according to the optimized detection parameters; during the detection process, ensure that the probe moves at a uniform speed along the moving track to ensure the comprehensiveness and accuracy of the detection, collect detection data in real time, including the echo information of the ultrasonic signal and the position information of the probe, and store the data in the storage medium of the detection equipment for subsequent analysis and processing, thereby improving the comprehensiveness and accuracy of weld defect detection.

[0067] Therefore, the customized tooling device in the embodiment of the present application realizes the stable installation and precise movement of the probe, and cooperates with the probe encoder to collect data in real time, which significantly improves the degree of automation of the detection process and reduces the uncertainty and complexity of manual operation, thereby greatly shortening the detection time and improving the detection efficiency.

[0068] In addition, the embodiments of the present application can make use of the powerful data analysis function of the phased array ultrasonic detection equipment, and combine with the reference data of the simulated test block to perform feature comparison analysis from multiple aspects such as the amplitude, phase, and propagation time of the reflected wave, and can accurately identify the inherent reflection point echo and the defect echo. This precise discrimination ability can effectively avoid misjudging the inherent reflection signal of the gradient angle weld as a defect, and at the same time can accurately judge the location, size and nature of the defect, greatly improving the accuracy of defect judgment.

[0069] Optionally, in one embodiment of the present application, after obtaining the phased array detection results of the gradient angle welds of the water diversion pressure steel pipe bends, it also includes: extracting ultrasonic detection data of the gradient angle welds of the target pressure steel pipe bends based on the phased array detection results; determining the target defects of the gradient angle welds of the target pressure steel pipe based on the ultrasonic detection data, and locating, quantitatively and qualitatively analyzing the target defects to obtain target analysis results; and comprehensively evaluating the degree of impact of the target defects on the safety of the water diversion pressure steel pipe bends based on the target analysis results.

[0070] In some embodiments, the embodiments of the present application can import the ultrasonic data of the gradient angle weld of the pressure steel pipe obtained by detection into the data analysis software, and use the software data analysis function, combined with the reference data of the simulated test block detection, by comparing the amplitude, phase, propagation time and other characteristics of the reflected wave, accurately identify the inherent reflection point echo of the phased array and the defect echo. For example, the inherent echo of the gradient angle weld moves continuously and slowly with the change of the angle. Then, a variety of defect assessment methods are used, such as the equivalent method, the length measurement method, etc., to locate, quantify and qualitatively analyze the defects. According to the position, size, shape and other information of the defects, the nature of the defects, such as cracks, lack of fusion, pores, etc., is judged. Taking into account the various parameters of the defects, the defects are comprehensively assessed to determine the degree of impact of the defects on the safety of the pressure steel pipe structure. For example, the impact level can be divided according to the degree of impact, which is more intuitive and provides a reliable basis for subsequent maintenance and processing.

[0071] For example, if Figure 2 As shown, the working principle of the embodiment of the present application is described in detail below with a specific embodiment.

[0072] Step S201: Collect the geometric parameters of the gradient angle weld of the penstock bend and create a 3D data model. Specifically, the present embodiment can accurately measure the various geometric parameters of the gradient angle weld between the penstock bend sections to construct a precise 3D data model that includes the weld's detailed geometry, dimensions, groove form, angle, and its relationship to the surrounding structure.

[0073] Step S202: Use phased array simulation software to simulate the weld to form a theoretical simulation process. In other words, the embodiment of the present application can use phased array simulation software to simulate welds with different curvature gradient angles to obtain optimal phased array detection process parameters and form a complete theoretical simulation process.

[0074] Step S203: Fabricate a simulated test block for a specific reflector, customize a probe and wedge for simulation process parameters, and process a scanning fixture adapted to the probe. Specifically, the present embodiment can customize a phased array probe and wedge with a specific frequency, array element arrangement, and wedge angle, and customize a fixture adapted to welds with tapered angles in curved pipes of different curvatures.

[0075] Step S204: Test and verify the simulated test block, optimize the parameters, and install an encoder. That is, the embodiment of the present application can detect the reflector in the gradient angle weld simulated test block, adjust the detection equipment parameters to make the detection signal reach the optimal state, record the reflector echo signal and compare it with the simulated test block marking information, verify the detection performance and optimize the detection parameters. Secondly, install the customized tooling device at the gradient angle weld of the pressure steel pipe, firmly fix it with a fixed bracket, and install a probe encoder on the probe moving track.

[0076] Step S205: Actual weld inspection, using data analysis functions to identify echoes and achieve comprehensive defect assessment. That is, the embodiment of the present application can be combined with simulated test block inspection reference data, by comparing the amplitude, phase, propagation time and other characteristics of the reflected wave, to identify the inherent reflection point echo of the phased array and the defect echo display, and adopt a variety of defect assessment methods to locate, quantify and qualitatively analyze the defects, and comprehensively assess the degree of impact of the defects on the safety of the penstock structure, thereby providing a scientific and reliable basis for the safe operation and maintenance decision-making of the water diversion penstock.

[0077] Therefore, the embodiment of the present application can use phased array technology to achieve rapid and accurate detection of internal defects in the gradient angle welds of the water diversion pressure steel pipe bends of the hydropower plant. The specially designed wedge blocks allow the sound field to fully cover the welds. Combined with data analysis, the inherent reflection echoes and defect echoes can be accurately distinguished, the detection blind spots are eliminated, and the accuracy of weld defect assessment is improved. At the same time, the detection process is optimized, the detection efficiency is improved, the cost is reduced, and the safe operation of the power station is guaranteed.

[0078] According to the phased array detection method for the gradient angle weld of the water diversion pressure steel pipe bend proposed in the embodiment of the present application, a target three-dimensional data model can be constructed based on the geometric parameters of the gradient angle weld of the pressure steel pipe bend section to determine at least one target phased array detection process parameter, so that a phased array probe and wedge can be prepared, and a tooling device can be designed. A phased array ultrasonic detection system can be established according to the corresponding relevant parameters, and the system can be optimized using a gradient angle weld simulation test block. The optimized phased array ultrasonic detection system can be used to perform phased array detection on the gradient angle weld of the water diversion pressure steel pipe to obtain detection results, effectively improving the efficiency and accuracy of weld internal defect detection. As a result, the problem that the weld detection method in the related art is difficult to adapt to the complex geometric shape and groove changes of the gradient angle weld, resulting in the inability to achieve blind spot detection and reduced efficiency and accuracy of weld internal defect detection is solved.
