[0037] In the related technology, synchrotron X-ray in-situ imaging technology can realize the dynamic observation of the interface reaction and solidification structure evolution between composite brazing materials and between brazing materials and base materials during the brazing process. It is necessary to build a brazing device that matches the synchrotron X-ray and prepare synchrotron in-situ imaging experimental samples. However, the synchrotron X-ray in-situ imaging experiment has certain requirements on the sample size. The sample size in the conventional brazing process cannot meet the requirements, and the synchrotron experimental samples need to be processed. The length and width of the processed sample size are limited by the constructed brazing device, and the thickness requirements of the sample are strict. When the sample is too thick, the X-rays cannot penetrate the sample, and the brazing interface and solidification structure evolution cannot be observed, and the experiment fails; when the sample is too thin, the sample is difficult to process, and the chemical reaction that occurs is different from the interface reaction in the conventional brazing process, and the experiment fails; therefore, there is a certain range for the sample thickness.

[0038] Composite solders are divided into flux-cored solders (solder skin-brazing flux-solder skin) and layered composite solders (first layer solder-second layer solder-third layer solder). During the brazing process, the composite solder is installed between the base materials, and the liquid solder or liquid solder will flow, which can easily lead to poor interface bonding between the composite solder and the base material, affecting the welding quality. Based on this, how to improve the bonding degree between the composite solder and the base material interface during brazing is a technical problem that technicians in this field need to solve urgently.

[0039] like Figure 1 and Figure 2 As shown, in order to solve the above-mentioned technical problems, an embodiment of the present application provides a welding fixture for synchrotron radiation, and the welding fixture for synchrotron radiation includes a fixture body 200, an insert and an adjusting member 100, the fixture body 200 has a welding cavity 210, and the welding cavity 210 has an open end; the adjusting member 100 is connected to the fixture body 200, and the adjusting member 100 is connected to the insert, the adjusting member 100 can drive the insert to move in a preset direction, and the movement of the insert is configured to enable it to enter and exit the welding cavity 210 from the open end.

[0040] This application aims to improve welding quality. The following is a description of the specific optimization measures and implementation details of the welding fixture used for synchrotron radiation:

[0041] Exemplarily, the adjusting member 100 is driven by a precision screw mechanism or a servo motor, so that the operator can fine-tune the depth of the insert in and out of the welding cavity 210, ensuring that the insert can accurately control the position of the composite solder during the preheating stage, and reducing the impact of poor interface bonding caused by solder flow. At the same time, the motor drive can realize automatic control, automatically adjust according to a preset program or sensor feedback, and improve the accuracy and repeatability of the operation. It should be emphasized here that the adjusting member 100 can also be other structures, as long as it can achieve the drive of the insert to move in and out of the welding cavity 210, for example, the adjusting member 100 drives the insert to move in a direction perpendicular to the end face of the opening end.

[0042] For example, a pressure sensor is added to obtain the pressure of the insert on the sample placed in the welding cavity 210, thereby adjusting the bonding degree between the base material and the solder. For example, the adjustment member 100 is connected to the insert via a pressure sensor to directly obtain the pressure acting on the sample in the welding cavity 210.

[0043] It should be noted that the inner contour of the welding cavity 210 is adapted to the outer shape of the sample. For example, the welding cavity 210 is a cuboid, and the outer shape of the sample is also a cuboid. In simple terms, the cross section of the sample has the same shape and size as the cross section of the welding cavity 210. Of course, in other embodiments, the inner contour of the welding cavity 210 is a cylinder, and the outer shape of the sample is also set to a cylinder; or, the inner wall contour of the welding cavity 210 is a cube, and the outer shape of the sample is also set to a cube.

[0044] By adapting the shapes of the welding cavity 210 and the sample to make them adaptive, the clamping force can be automatically adjusted according to the size of the placed base material and composite solder, ensuring that a stable contact pressure is maintained between the materials during the entire welding process, reducing displacement and gap generation, and improving welding quality.

[0045] For example, the fixture body 200 and the insert are made of high-performance materials that are resistant to high temperatures and corrosion, and undergo special surface treatment, such as coating or plating, to reduce chemical reactions between the materials and the brazing material, thereby improving service life and welding quality.

[0046] Obviously, through the implementation of the above technical solutions, the welding fixture used for synchrotron radiation not only effectively solves the problem of interface bonding between composite solder and base material, but also improves welding accuracy and efficiency through intelligent and automated design, meeting the needs of modern industry for high-quality welding.

[0047] Of course, in other embodiments, a temperature sensor and a heating element are integrated in the fixture body 200 to monitor and control the temperature of the welding cavity 210, ensuring uniform temperature during the brazing process, avoiding local overheating or underheating, further optimizing the metallurgical bonding process between the brazing material and the base material, and improving the bonding strength and uniformity of the welding interface.

[0048] like Figure 1 and Figure 3 As shown, in some embodiments, the adjusting member 100 includes a cover plate 120 and an adjusting bolt 110, the cover plate 120 is connected to the clamp body 200, a threaded hole 121 passes through the cover plate 120, and the axial direction of the threaded hole 121 is parallel to the preset direction; the adjusting bolt 110 is threadedly connected to the hole wall of the threaded hole 121, and the adjusting bolt 110 is connected to the insert.

[0049] In these embodiments, the design of the adjusting member 100 further improves the practicality and operational convenience of the welding fixture for synchrotron radiation by introducing the structure of the cover plate 120 and the adjusting bolt 110 .

[0050] The adjusting bolt 110 is combined with the threaded hole 121 on the cover plate 120, and the mechanical principle of the thread can be used to achieve fine-tuning control of the moving distance of the insert. The operator only needs to rotate the adjusting bolt 110 to push or pull the insert in a preset direction. This adjustment method has high precision and can finely control the position of the insert according to actual welding requirements, thereby ensuring the best bonding state between the composite brazing material and the base material.

[0051] The design of the cover plate 120 makes the installation and operation of the adjustment bolt 110 more intuitive and convenient. The user can quickly adjust without complicated tools, which improves the efficiency of welding preparation work and reduces the difficulty of operation. Even non-professional workers can easily master the use method.

[0052] The threaded connection ensures stability and firmness of the connection during the adjustment process. During the adjustment process, the close fit between the bolt and the threaded hole 121 can effectively resist vibration and external force interference generated during the welding process, avoid accidental movement of the adjustment member 100, and ensure the stability of the welding process and the consistency of the welding results.

[0053] Among them, the detachable design of the cover plate 120 and the fixture body 200 makes it easy to clean, maintain or replace the adjusting bolt 110 or the threaded hole 121 if they are worn after long-term use, thereby extending the overall service life of the welding fixture for synchrotron radiation and reducing maintenance costs.

[0054] Obviously, by selecting the length of the adjusting bolt 110 and setting the adjustment range, the design can adapt to the combination of base materials and composite solders of different thicknesses, increasing the versatility of the welding fixture for synchrotron radiation and its applicability in various welding tasks. In summary, by adopting the design of the adjusting member 100 combining the cover plate 120 with the adjusting bolt 110, not only the accuracy of positioning and controlling the composite solder during the welding process is improved, but also the user-friendliness, stability and maintenance convenience of the welding fixture for synchrotron radiation are enhanced, which is an important technical innovation for improving welding quality and work efficiency.

[0055] For example, the cover plate 120 fits the end surface of the opening end, and the end surface of the opening end is provided with a first fastening threaded hole 230, and the cover plate 120 is provided with a through hole 122, so that the fastening bolt can pass through the through hole 122 and be threadedly connected to the first fastening threaded hole 230, thereby realizing a detachable connection between the cover plate 120 and the fixture body 200. Of course, in other embodiments, the cover plate 120 can also be provided with a second fastening threaded hole 121 to replace the through hole 122, and the fastening bolt is connected to the second fastening threaded hole 121 and the first fastening threaded hole 230 in sequence.

[0056] For example, the adjusting bolt 110 and the insert are integrated. Alternatively, the head of the adjusting bolt 110 forms the insert. Of course, in other embodiments, the insert can be fixed to the adjusting bolt 110 by welding or bonding.

[0057] like Figure 1 As shown, in the above embodiment, the number of the adjusting bolts 110 is set to be multiple, and the multiple adjusting bolts 110 are arranged at intervals along the length direction and / or the width direction of the opening end.

[0058] For example, the number of the adjusting bolts 110 is set to 3, and the 3 adjusting bolts 110 are arranged at intervals along the length direction of the opening end. Of course, in other embodiments, the number of the adjusting bolts 110 can also be set to 2, 4, 5, 6, etc., which is not specifically limited here.

[0059] Obviously, by increasing the number of adjusting bolts 110 , it can be ensured that almost all parts of the sample can withstand the pressure of the insert, thereby further improving the brazing effect.

[0060] like Figure 1 As shown, in some embodiments, the welding fixture for synchrotron radiation also includes a gasket 300, which can enter and exit the welding cavity 210 from the open end; in the working state, the gasket 300 is clamped between the sample and the insert placed in the welding cavity 210.

[0061] In these embodiments, the welding fixture for synchrotron radiation introduces a design element, the gasket 300, which is placed between the sample and the insert. Under pressurized conditions, the gasket 300 can be used to evenly distribute the pressure of the insert on the upper end of the sample, thereby ensuring the bonding degree between the base material and the solder at various locations, thereby improving the bonding quality and uniformity of the welding interface.

[0062] For example, the shape of the gasket 300 is the same as the cross section of the welding cavity 210, and the gasket 300 and the welding cavity 210 are clearance-matched. For example, the gasket 300 is set as a cuboid, and the welding cavity 210 is also set as a cuboid. Alternatively, the gasket 300 is set as a cube, and the welding cavity 210 is also set as a cube; alternatively, the gasket 300 is set as a cylinder, and the welding cavity 210 is also set as a cylinder, and so on.

[0063] As an isolation material, the gasket 300 can prevent the sample from directly contacting the hard surface of the insert, reducing scratches or damage to the sample surface. Since the insert rotates with the adjusting bolt 110, the role of the gasket 300 is particularly critical, especially when processing delicate or fragile materials.

[0064] In addition, due to the rotational wear of the insert and the gasket 300, the gasket 300 is designed as a consumable part as a separate component, so that after long-term use, once the gasket 300 is worn or contaminated, it can be quickly and easily replaced without the need to disassemble the fixture as a whole, thereby reducing maintenance time and costs and increasing the continuous operation capacity and service life of the equipment.

[0065] like Figure 1 and Figure 2 As shown, in some embodiments, the side wall of the fixture body 200 has a transmission area, which allows the X-ray imaging light path 400 to be transmitted, and the distribution position of the transmission area is configured to enable the X-ray imaging light path 400 to pass through the fixture body 200, and the welding cavity 210 is within the coverage range of the X-ray imaging light path 400.

[0066] In these embodiments, the strategy of incorporating the transmission area into the design of the fixture body 200 significantly enhances the monitoring and quality control capabilities of the welding process.

[0067] By setting a transmission area on the side wall of the fixture body 200, X-rays can directly penetrate the fixture body 200 and the welding cavity 210, providing a physical path for the use of X-ray imaging technology. This enables the operator or the automated monitoring system to implement real-time monitoring during the welding process, and observe the state of the welding interface without interrupting the operation, including weld formation, solder flow, defect formation, etc., which greatly improves the transparency and controllability of the welding process.

[0068] Among them, X-rays have strong penetrating power and can penetrate metals and other materials with high density. Therefore, even when the welding fixture and parent material used for synchrotron radiation are thick, clear internal images can be obtained through the transmission area. This makes the evaluation of welding quality more accurate, and welding defects such as pores, cracks, and lack of fusion can be discovered and corrected in time, thereby ensuring the reliability and consistency of the welded joint.

[0069] In addition, the material of the transmission area must be carefully selected to ensure that it can transmit X-rays and meet the temperature and mechanical stress tolerance during welding. Usually, low atomic number materials (such as carbon fiber reinforced plastics, special ceramics or lightweight alloys) are selected to make the transmission area. These materials have sufficient mechanical strength and heat resistance while ensuring X-ray transmittance.

[0070] In welding quality control, the integration of X-ray imaging technology means that non-destructive testing (NDT) can be carried out, which is particularly important for ensuring the integrity of safety-critical structures. Inspection can be completed without destroying samples or fixtures, reducing inspection costs and speeding up inspections while preserving the original state of the weld.

[0071] Obviously, the design of the transmission area allows the welding process to be seamlessly connected with advanced image analysis software and automated control systems. Through real-time analysis of X-ray images, the system can automatically adjust welding parameters, stop welding for intervention, or conduct quality assessment immediately after welding is completed, promoting the development of intelligent manufacturing.

[0072] Of course, in other embodiments, a high-definition camera or an infrared thermal imaging system is integrated to monitor the status of the welding interface, such as the flow of solder, the interface gap, etc., in real time, and through image processing and analysis technology, it is instantly fed back to the control system to automatically adjust the welding parameters or the position of the adjustment member 100 to achieve closed-loop control of the welding process.

[0073] Exemplarily, the welding cavity 210 is set to be square, and the welding cavity 210 has a first direction and a second direction that intersect vertically, and the open end is set upward. The samples are placed in a stacked manner from top to bottom. During operation, the bottom layer and the top layer are respectively the base materials, and the solder is placed between the base materials. The insert is driven to move from top to bottom to compress the sample. Among them, if the X-ray imaging optical path 400 propagates along the first direction, the side wall of the welding cavity 210 located in the first direction can be set as the transmission area, so that the entire welding cavity 210 can be completely exposed to the X-ray imaging optical path 400.

[0074] Of course, if the X-ray imaging optical path 400 propagates along the second direction, the side wall of the welding cavity 210 located in the second direction can be set as a transmission area, so that the entire welding cavity 210 can be completely exposed to the X-ray imaging optical path 400.

[0075] Exemplarily, the fixture body 200 includes a plurality of side panels, which are arranged to form the welding cavity 210. The side panels located in the X-ray imaging optical path 400 can be set as the transmission area. It is easy to understand that the side panels can be set to be made of a material that allows X-rays to be transmitted.

[0076] In some embodiments, the thickness of the side wall of the welding cavity 210 on the X-ray imaging optical path 400 is T, which satisfies: 0.5 mm ≤ T ≤ 3 mm.

[0077] That is, in these embodiments, the thickness T of the side wall of the welding cavity 210 is designed to be in the range of 0.5 mm to 3 mm, aiming to balance multiple key factors and ensure the feasibility of X-ray imaging and the practicality of the welding process.

[0078] The set thickness range ensures good X-ray transmittance. Thinner sidewalls (at least 0.5 mm) can reduce X-ray attenuation, allowing the imaging system to capture images inside the welding area more clearly, which is crucial for detecting welding quality, such as identifying the integrity of the weld and whether there are defects (such as pores and cracks). At the same time, limiting the maximum thickness to no more than 3 mm avoids strong absorption of X-rays by overly thick materials, ensuring image contrast and resolution.

[0079] Although thin walls are good for transmission, they also need to have sufficient mechanical strength to withstand the temperature and pressure during welding. The thickness is between 0.5 mm and 3 mm, which can ensure that the side wall is not easily deformed in a high temperature environment, and maintain structural stability when subjected to welding stress, which is very important for maintaining the shape and dimensional accuracy of the welding cavity 210, as well as durability for long-term use.

[0080] Within this thickness range, a variety of materials can be selected to manufacture the side walls of the welding cavity 210, including but not limited to aluminum alloy, stainless steel, special ceramics, etc. These materials not only meet the requirements of X-ray transmission, but also have good heat resistance, corrosion resistance or high strength properties. The most suitable material can be selected based on the specific welding process and cost considerations.

[0081] For example, the thickness of the side wall is set to 0.5 mm. Of course, in other embodiments, the thickness of the side wall can also be set to 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3.0 mm.

[0082] In some embodiments, at least a portion of the side wall of the fixture body 200 located on the X-ray imaging optical path 400 is configured to be composed of an aluminum oxide plate or a graphite plate.

[0083] In these embodiments, an aluminum oxide plate or a graphite plate is selected as the material of at least part of the side wall of the fixture body 200 located on the X-ray imaging optical path 400. This design has many advantages and considerations:

[0084] X-ray transmittance: Alumina and graphite both have good X-ray transmittance. Although alumina is a ceramic material, its low atomic number makes it relatively less absorbent of X-rays; graphite is widely used as an X-ray window material due to its low density and high transmittance to X-rays. This design ensures that X-rays can effectively penetrate the side wall of the fixture without causing excessive attenuation, thereby ensuring the clarity and quality of X-ray imaging.

[0085] High temperature resistance: High temperatures are generated during welding, and both alumina and graphite have excellent high temperature resistance. Alumina refractory materials can withstand high temperatures without deformation or damage, and the same is true for graphite, which can maintain its structural stability even at extremely high temperatures. This allows them to maintain good performance in high temperature working environments such as welding, without deformation or damage due to heat, ensuring the stability and safety of the welding process.

[0086] Alumina and graphite both have good chemical stability and are not easy to react with various chemical substances produced during the welding process, thus avoiding material corrosion or contamination of the welding area, ensuring the welding quality and long-term reliability of the equipment.

[0087] Of course, it can also be set to other plates that allow X-rays to transmit, which is not specifically limited here.

[0088] like Figure 1 and Figure 2 As shown, in some embodiments, the side wall of the welding cavity 210 is detachably connected with a mica board 220 , and the mica board 220 can cover the side wall of the welding cavity 210 corresponding thereto.

[0089] In these embodiments, the design of the side wall of the welding cavity 210 to be detachably connected to the mica board 220 brings additional flexibility and advantages to the welding process and quality control. The mica board 220 is used as an additional layer covering the side wall of the welding cavity 210 due to its excellent high temperature resistance and good electrical insulation properties. This can not only effectively protect the welding fixture used for synchrotron radiation from high temperature, reduce thermal deformation or damage, but also prevent electric sparks or current leakage, and increase the safety of the welding process.

[0090] The mica plate 220 is connected in a detachable manner, making the operation easier and faster when welding different materials or when maintenance or replacement is required. The mica plate 220 can be easily installed or removed according to actual welding requirements, which is convenient for adapting to the needs of different welding processes. It also simplifies the inspection and replacement process of the mica plate 220 itself, and prolongs the overall service life of the welding fixture used for synchrotron radiation.

[0091] The mica plate 220 on the side wall of the welding cavity 210 can be customized according to the characteristics of the specific welding task, such as thickness, size, and whether holes are required to accommodate a specific X-ray imaging optical path 400 or other monitoring equipment. This design flexibility provides the possibility of meeting diverse welding requirements and optimizing welding quality.

[0092] For example, by replacing mica plates 220 of different sizes, the volume and shape of the welding cavity 210 can be changed to adapt to different sample welding. In other words, the welding cavity 210 is designed to be adjustable in size or shape, and through replaceable gaskets or modular components, it can adapt to different sizes and shapes of base materials and composite solder combinations, thereby increasing the versatility and flexibility of the welding fixture for synchrotron radiation.

[0093] In addition, the use of mica plate 220 can also isolate the molten solder that may be generated during the welding process from direct contact with the welding fixture material (such as alumina) used for synchrotron radiation to a certain extent, avoiding unnecessary chemical reactions or contamination, and further ensuring the purity of the welding interface and the welding quality.

[0094] It should be noted that in the welding process involving X-ray imaging monitoring, the transparency of the mica board 220 (to X-rays) allows the X-rays to penetrate smoothly without significantly affecting the imaging quality, thereby ensuring visual monitoring of the welding process and timely detection of defects.

[0095] like Figure 2 As shown, in some embodiments, the mica boards 220 abut against corresponding side walls of the welding cavity 210 , and adjacent mica boards 220 abut against each other.

[0096] In these embodiments, the mica board 220 is closely abutted against the side wall of the welding cavity 210, and adjacent mica boards 220 are well butted against each other. The mica board 220 is closely abutted against the side wall of the welding cavity 210, and adjacent mica boards 220 are butted against each other without gaps, which can effectively improve the sealing of the welding area. This sealing design helps prevent solder, flux or other substances from penetrating into the fixture during high-temperature welding, keeps the welding environment clean, and avoids affecting the welding quality.

[0097] The tight abutment reduces the risk of deformation or displacement caused by high temperature during welding and increases the overall structural stability of the welding fixture for synchrotron radiation, which is essential for maintaining accurate welding positions and ensuring the morphological consistency of the welding cavity 210, especially in situations where high-precision welding operations are required.

[0098] Among them, good contact helps to evenly conduct and manage heat energy. The mica board 220 acts as a heat barrier, and its close docking can more evenly distribute the heat generated during welding, avoid local overheating, protect welding equipment, and also help control the heat affected area during welding and improve welding quality.

[0099] In addition, the mica board 220 of this design is easy to disassemble, and can be operated relatively simply when replacement or maintenance is required, and the close docking design connection between adjacent mica boards 220 only requires taking and placing to complete disassembly and assembly.

[0100] Of course, in other embodiments, the detachable connection between the mica board 220 and the welding cavity 210 may also be achieved by other methods.

[0101] Exemplarily, the two side plates in the first direction are located between the two side plates in the second direction, and both ends of the side plates in the first direction are respectively abutted against the two side plates in the second direction.

[0102] like Figure 1 As shown, in some embodiments, the welding fixture for synchrotron radiation further includes a displacement control platform 500 , which is connected to the fixture body 200 , and the displacement control platform 500 can adjust the position of the fixture body 200 .

[0103] In these embodiments, the displacement control platform 500 is introduced as a part of the welding fixture for synchrotron radiation, and the displacement control platform 500 can achieve fine adjustment of the three-dimensional spatial position of the fixture body 200, including adjustment of up and down, left and right, front and back, and rotation angle. This precise control capability ensures that the welding area is always in the ideal processing position, which is crucial to improving the accuracy and consistency of the welding point, especially when processing workpieces with complex geometries or high precision requirements.

[0104] For example, the displacement control platform 500 is usually equipped with an electric, pneumatic or hydraulic drive system to achieve automatic control. Through programming or remote control, it can quickly respond to the position adjustment requirements during the welding process, improve production efficiency and flexibility, reduce manual intervention, and reduce labor intensity.

[0105] Among them, precise position control helps to reduce welding defects such as misalignment and uneven welds, thereby improving the overall quality and appearance of the welded products. At the same time, automated adjustment reduces preparation and adjustment time, speeds up the welding cycle, and improves overall production efficiency.

[0106] In some embodiments, the present application also provides a welding system, which includes a welding fixture for synchrotron radiation as described in any one of the above embodiments.

[0107] Since the above-mentioned welding fixture for synchrotron radiation has the above-mentioned technical effects, the welding system including the welding fixture for synchrotron radiation should have the same technical effects, which will not be repeated here.

[0108] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
