Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a method for determining the coverage area of ​​a welding workpiece and related components. Background Technology

[0002] Before actual welding production, multiple working specimens need to be made. Verification of the working specimens is an important means to ensure welding quality. The verification results are usually recorded manually in paper ledgers to generate verification reports for each working specimen. These reports record key data corresponding to the verification operations, such as the corresponding weld joints.

[0003] Each working specimen has a corresponding coverage area, which reflects which welding conditions the specimen can cover. In existing technologies, a welding project may have multiple weld joints. To reduce workload, it's unnecessary to verify all of them using working specimens. Instead, technicians manually analyze the details of previously verified weld joints to determine the coverage area of ​​each working specimen. This involves manually consulting welding standards and specifications, as well as paper records, to determine the coverage area based on the standards and specifications. This clarifies which weld joints in the welding project do not require further working specimen verification. However, this method is cumbersome, labor-intensive, and inefficient in coverage analysis, wasting human resources. Even for the same verified working specimen, the coverage area analyzed by different technicians often differs due to their experience, resulting in poor knowledge transfer. The probability of repeated working specimen verification due to misanalysis is also high. Furthermore, the manual management and paper record system is not conducive to the management and application of working specimens.

[0004] Therefore, how to effectively and reliably determine the coverage area of ​​the working specimen is an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a method and related components for determining the coverage area of ​​welding work specimens. The method for determining the coverage area is more automatic, simple, and efficient, which reduces the probability of redundant specimen verification caused by erroneous analysis of work specimens to a certain extent. In addition, the method for managing each second work specimen is also more efficient, which is beneficial to practical production applications.

[0006] To solve the above-mentioned technical problems, the present invention provides a method for determining the coverage area of ​​a welding test piece, comprising:

[0007] To obtain the verification purpose and key information of the first working specimen with the coverage area to be determined;

[0008] Based on the verification purpose and the key information, a search is performed in the preset working specimen database. The preset working specimen database includes multiple second working specimens with verified coverage. Each second working specimen includes basic welding information, a preset verification purpose, and a preset coverage corresponding to the preset verification purpose. The preset coverage is predetermined based on the basic welding information and the stored preset welding standards and specifications corresponding to the preset verification purpose.

[0009] Determine whether each of the second working specimens contains a selected second working specimen whose preset verification purpose includes the verification purpose and whose basic welding information includes the key information;

[0010] If so, the preset coverage area of ​​the selected second working specimen is determined to be the coverage area of ​​the first working specimen.

[0011] Preferred options also include:

[0012] When it is determined that the selected second working specimen does not exist in any of the second working specimens, the welding standard specification corresponding to the verification purpose is determined based on the preset working specimen database.

[0013] The welding standard specifications, the verification purpose, and the key information are input into a pre-trained coverage determination model;

[0016] The key data elements include joint code information, welding method information, weld size information, weld category information, material information, front detail information, back detail information, bevel type information, thickness information, welding position information, group information, and heat input information.

[0017] The preset coverage scope corresponding to the preset verification purpose includes the key element data that can be covered, which corresponds one-to-one with each of the key element data.

[0018] Preferably, the basic welding information of the i-th second working specimen also includes process information data characterizing the welding process and quality requirements adopted therein, wherein 1≤i≤the total number of the second working specimens and i is an integer;

[0019] The process information data includes process specification data, process evaluation data corresponding to the process specification data, welder qualification data, welding defect level data, welding quality level data, inspection level data and inspection requirement data corresponding to the welding defect level data.

[0020] Preferred options also include:

[0021] Obtain the classification information input by the user for finding similar working specimens;

[0022] Based on the classification information, a search is performed on the basic welding information and / or preset verification objectives of each second working specimen to determine whether there is a second working specimen corresponding to the classification information.

[0023] Preferred options also include:

[0024] The identifier signal that acquires user input and summarizes the data according to a preset output format;

[0025] Based on the identification signal, all information included in each of the second working specimens is summarized to generate a file in the preset output format.

[0026] Preferred options also include:

[0027] Obtain the input information of the third working specimen for the working condition to be analyzed, as input by the user;

[0028] Based on the input information, a search is performed on the basic welding information of each second working specimen and the preset verification purpose and preset coverage range to determine whether there is a target second working specimen that can cover the third working specimen.

[0029] To address the aforementioned technical problems, the present invention also provides a system for determining the coverage area of ​​welding test specimens, comprising:

[0032] The judgment unit is used to determine whether there is a selected second working specimen in each of the second working specimens whose preset verification purpose includes the verification purpose and whose basic welding information includes the key information; if so, the coverage determination unit is triggered.

[0033] The coverage determination unit is used to determine that the preset coverage of the selected second working specimen is the coverage of the first working specimen.

[0034] To address the aforementioned technical problems, the present invention also provides a device for determining the coverage area of ​​a welding work specimen, comprising:

It eliminates the need for paper-based management of verified test specimens by establishing a pre-defined database of second test specimens. Each second test specimen includes a pre-determined coverage area based on basic welding information and pre-defined welding standards and specifications corresponding to a pre-defined verification purpose. The method then searches the database for the verification purpose and key information of the first test specimen whose coverage area needs to be determined, ultimately identifying the pre-defined coverage area of ​​the selected second test specimen as the coverage area of ​​the first test specimen. Compared to existing technologies, this method is more automatic, simpler, and more efficient in determining coverage, reducing the probability of redundant test specimen verification due to erroneous analysis of test specimens. Furthermore, the management of each second test specimen is more efficient, which is beneficial for practical production applications. Attached Figure Description

[0046] The core of this invention is to provide a method for determining the coverage area of ​​welding working specimens and related components. The method for determining the coverage area is more automatic, simple, and efficient, which reduces the probability of redundant specimen verification caused by erroneous analysis of working specimens to a certain extent. In addition, the management method of each second working specimen is also more efficient, which is beneficial to practical production applications.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Please refer to Figure 1 , Figure 1 A flowchart of a method for determining the coverage area of ​​a welding test piece provided by the present invention.

[0049] In this embodiment, considering that the existing technology records and stores verification reports for each working specimen using paper ledgers, it is not conducive to actual production management; and determining the coverage of each working specimen requires manual analysis by technicians, who manually consult welding standards and specifications and paper ledgers to determine the coverage of each working specimen. However, this method is too cumbersome, labor-intensive, has low efficiency in coverage analysis, and poor knowledge transferability, which is not conducive to practical production applications. To solve the above technical problems, this application provides a method for determining the coverage of welding working specimens, which realizes automatic, efficient, and simple management of working specimens, and is convenient for practical applications.

[0050] The method for determining the coverage area of ​​the welding test piece includes:

[0051] S11: Obtain the verification purpose and key information of the first working specimen with the coverage area to be determined;

[0052] Specifically, this method can be applied to various computer devices, including servers and clients. This application does not make any special limitations here. The purpose of the verification is to produce working specimens, specifically including verifying quality, verifying skills, verifying design and verifying process. The key information is used to characterize the basic welding information corresponding to the first working specimen with the coverage to be determined.

[0053] In addition, the specific method for obtaining the input information corresponding to the first working specimen can be: relying on the information input by the user in the human-computer interaction interface.

[0054] S12: Search the preset working specimen database based on the verification purpose and key information. The preset working specimen database includes multiple second working specimens with verified coverage. Each second working specimen includes basic welding information, preset verification purpose and preset coverage corresponding to the preset verification purpose. The preset coverage is predetermined based on the basic welding information and the stored preset welding standard specifications corresponding to the preset verification purpose.

[0055] Specifically, the pre-set working specimen database stores multiple second working specimens. The pre-set verification purpose of each working specimen is still one or more combinations of verifying skills, verifying design, and verifying processes. Considering engineering practice, the specific verification purposes for which the second working specimen is verified depend on actual needs, but typically it mainly verifies processes and verifyes skills. Furthermore, the pre-set working specimen database also stores welding standards and specifications corresponding to all the above verification purposes. Specifically, for verifying skills, the welding standards and specifications include welding skill assessment-related standards and rules, such as EN ISO 9606-1 / 2; for verifying quality, the welding standards and specifications include welding quality-related standards and rules, such as EN 15085-4; for verifying processes, the welding standards and specifications include welding process-related standards and rules, such as EN ISO 15614-1 / 2; and for verifying design, the welding standards and specifications include welding design verification-related standards and rules, such as EN 15085-3. Please refer to... Figure 2 , Figure 2 This is a schematic diagram of the structure of a preset working specimen database provided by the present invention. Here, only one second working specimen and four preset verification purposes are used as an example for illustration.

[0056] It should also be noted that the preset coverage range stored in each second working specimen can be obtained and stored in advance by welding experts through expert review, which is more authoritative and accurate. Alternatively, a more intelligent and convenient method can be adopted, namely, using a pre-trained neural network model (coverage determination model) based on a large dataset to determine the preset coverage range of each second working specimen; no particular limitation is made here. It can be seen that, regardless of the method, subsequent technicians do not need to manually consult and analyze paper ledger details, which reduces the probability of redundant specimen verification to some extent.

[0057] S13: Determine whether there is a selected second working specimen in each second working specimen with a preset verification purpose including the verification purpose and basic welding information including key information; if so, trigger S14.

[0058] Specifically, the search process described above can be described as follows: First, second working specimens with preset verification purposes that include the verification purpose of the first working specimen are selected. Then, the basic welding information corresponding to these second working specimens is searched to determine whether there are selected second working specimens whose basic welding information includes the key information of the first working specimen. Of course, this search process can also be described as follows: First, second working specimens with preset verification purposes that include the key information of the first working specimen are selected. Then, the preset verification purposes corresponding to these second working specimens are searched to determine whether there are selected second working specimens whose verification purpose includes the first working specimen. No special limitation is made here. It can be determined according to the actual written underlying search program, and the search logic of S13 can be implemented.

[0059] S14: Determine that the preset coverage area of ​​the selected second working specimen is the coverage area of ​​the first working specimen.

[0060] It is understood that after step S14, the determined coverage area can be displayed through a display module, which includes, but is not limited to, a display screen.

[0061] This application provides a method for determining the coverage of welding test specimens. It eliminates the need for paper-based management of verified test specimens by establishing and maintaining a pre-defined database of second test specimens. Each second test specimen includes a pre-defined coverage area based on basic welding information and pre-defined welding standards and specifications corresponding to a pre-defined verification purpose. The method then searches the database for the verification purpose and key information of the first test specimen whose coverage area needs to be determined, ultimately identifying the pre-defined coverage area of ​​the selected second test specimen as the coverage area of ​​the first test specimen. Compared to existing technologies, this method is more automatic, simpler, and more efficient in determining coverage, reducing the probability of redundant test specimen verification due to erroneous analysis of test specimens. Furthermore, the management of each second test specimen is more efficient, which is beneficial for practical production applications.

[0062] Based on the above embodiments:

[0063] As a preferred embodiment, it also includes:

[0064] When it is determined that the selected second working specimen does not exist in any of the second working specimens, the welding standard and specification corresponding to the verification purpose are determined based on the preset working specimen database.

[0065] The welding standards and specifications, verification objectives, and key information are input into a pre-trained coverage model to determine the scope.

[0066] The coverage area is determined by the output of the model, which is the coverage area of ​​the first working specimen.

[0067] In this embodiment, the inventors further considered that different welding projects may not have a corresponding second working specimen pre-stored in the preset working specimen database. Therefore, the welding standards and specifications corresponding to different verification purposes are naturally different, and the determined coverage is also different. Therefore, when it is determined that there is no selected second working specimen, the coverage of the first working specimen can be automatically determined according to the above process. The specific implementation steps are described above and will not be repeated here.

[0068] It should be noted that the pre-trained coverage determination model is essentially a neural network model trained on a large dataset. This neural network model includes, but is not limited to, one or more combinations of BP neural networks, convolutional neural networks, recurrent neural networks, and long short-term memory neural networks, without any particular limitation here.

[0069] It should also be noted that when it is determined that the selected second working specimen does not exist among the second working specimens, a feedback signal indicating that no relevant information was found in the preset working specimen database can be output first, and then the final coverage determined by the coverage determination model can be output. In order to further improve the accuracy of the final coverage, after outputting the feedback signal, the user can be prompted whether to add key information about the first working specimen before executing the above steps of inputting the model. It is understood that the more key information is input, the higher the accuracy of the final determined coverage will be, and no special limitation is made here.

[0070] It is evident that the design of the coverage determination model described above simply and reliably ensures the determination of the coverage for the first working specimen.

[0071] As a preferred embodiment, the basic welding information of the i-th second working specimen includes key element data characterizing the details of the welding process;

[0072] Key data elements include joint code information, welding method information, weld size information, weld category information, material information, front detail information, back detail information, groove type information, thickness information, welding position information, group information, and heat input information;

[0073] The preset coverage scope corresponding to the preset verification purpose includes the key element data that can be covered, which corresponds one-to-one with the key element data.

[0074] This embodiment provides the basic welding information for each second working specimen, which may include key element data characterizing the welding process details. The specific content of the key element data is as described above and will not be repeated here. It is understood that, depending on the actual application needs, other data characterizing the welding process details can be added to this key element data. Alternatively, only one or more combinations of the key element data described above can be used; no particular limitation is made here.

[0075] Specifically, the corresponding preset coverage includes: coverable joint code information corresponding to the joint code information in the key element data and corresponding one-to-one with each preset verification purpose; coverable welding method information corresponding to the welding method information in the key element data and corresponding one-to-one with each preset verification purpose; coverable weld size information corresponding to the weld size information in the key element data and corresponding one-to-one with each preset verification purpose; coverable weld category information corresponding to the weld type information in the key element data and corresponding one-to-one with each preset verification purpose; coverable material information corresponding to the material information in the key element data and corresponding one-to-one with each preset verification purpose; and coverable front detail information corresponding to the front detail information in the key element data and corresponding one-to-one with each preset verification purpose. The corresponding coverable front detail information; the coverable back detail information corresponding to the back detail information in the key element data and corresponding to each preset verification purpose; the coverable bevel type information corresponding to the bevel type information in the key element data and corresponding to each preset verification purpose; the coverable thickness information corresponding to the thickness information in the key element data and corresponding to each preset verification purpose; the coverable welding position information corresponding to the welding position information in the key element data and corresponding to each preset verification purpose; the coverable group information corresponding to the group information in the key element data and corresponding to each preset verification purpose; and the coverable heat input information corresponding to the heat input information in the key element data and corresponding to each preset verification purpose.

[0076] In a preferred embodiment, the basic welding information of the i-th second working specimen also includes process information data characterizing the welding process and quality requirements adopted therein, wherein 1≤i≤the total number of second working specimens and i is an integer;

[0077] Process information data includes process specification data, process evaluation data corresponding to the process specification data, welder qualification data, welding defect level data, welding quality level data, inspection level data and inspection requirement data corresponding to the welding defect level data.

[0078] In this embodiment, which is closer to practical applications, the basic welding information of each second working specimen can further include process information data characterizing the welding process and quality requirements adopted for the second working specimen, as described above, and will not be repeated here. It is understood that, depending on the actual needs of the application, other data characterizing the welding process and quality requirements can be added to the process information data. Of course, it is also possible to use only one or more combinations of the process information data described above, without any particular limitation here.

[0079] Furthermore, the inspection grade data corresponding to the welding defect grade data mentioned above can essentially be described as follows: a higher welding defect grade data corresponds to a higher inspection grade data, and similarly, a higher inspection grade data corresponds to a higher inspection requirement data.

[0080] It should also be noted that, since the preset working specimen database includes multiple second working specimens, each second working specimen can be numbered, which is more conducive to management and program identification.

[0081] As an example, assuming the purpose of the first working specimen obtained is to verify skills, the key information is: welding method: 131-PM; joint code: 11c; plate thickness: 4+4; welding position: PF; Table 1 shows the determination results of the coverage of the first working specimen obtained by the method provided in this application. Due to the limited space of the table, only the coverage information corresponding to the key information input is shown here.

[0084] As a preferred embodiment, it also includes:

[0085] Obtain the classification information input by the user for finding similar working specimens;

[0086] Based on the classification information, a search is performed on the basic welding information and / or preset verification purpose of each second working specimen to determine whether there is a second working specimen corresponding to the classification information.

[0087] In this embodiment, a preset working specimen database established in this application is provided, which can also realize the function of data collection. For the input classification information, a search can be performed according to the above logic. When it is determined that there is a second working specimen corresponding to the classification information (i.e., a second working specimen whose storage content includes the classification information), data collection of the same category can be realized.

[0088] Specifically, the input classification information can be identified. When the input classification information contains first information related to the verification purpose, a search should be performed in the preset verification purpose of each second working specimen. When the input classification information contains second information related to basic welding information, a search should be performed in the basic welding information of each second working specimen.

[0089] Understandably, after determining that one or more second working specimens corresponding to the classification information exist, they can be output and displayed so that users can obtain relevant information.

[0090] As an example, based on the above embodiments, assuming the input classification information is: weld type is B-BW joint and the verification purpose is skill verification, then data can be collected and classified according to the above logic. Please refer to... Figure 3 , Figure 3 This is a schematic diagram showing the data collection results provided by the present invention, which relies on a preset working specimen database to achieve data collection and classification. It should be noted that the scope of acceptance refers to the coverage described in this application.

[0091] As can be seen, the above method reliably realizes the collection logic of data of the same category, enriching the functionality of the pre-set working specimen database.

[0092] As a preferred embodiment, it also includes:

[0093] The identifier signal that acquires user input and summarizes the data according to a preset output format;

[0094] Based on the identification signal, all information included in each second working specimen is summarized to generate a file in a preset output format.

[0095] This embodiment provides a preset working specimen database established in this application, which can also realize the function of aggregating all stored data, thereby enriching the functionality of the preset working specimen database. Specific details are as described above and will not be repeated here. It should be noted that the preset output format here includes, but is not limited to, an xls format file to generate a working specimen information form.

[0096] It is understandable that after the file is generated, the display module can be controlled to display the contents of the file so that users can intuitively obtain relevant information.

[0097] It should also be noted that the user can send the identification signal through a human-computer interaction interface, and the user will confirm that the identification signal has been sent when they click on the details summary.

[0098] As a preferred embodiment, it also includes:

[0099] Obtain the input information of the third working specimen for the working condition to be analyzed, as input by the user;

[0100] Based on the input information, a search is performed on the basic welding information, preset verification purpose, and preset coverage of each second working specimen to determine whether there is a target second working specimen that can cover the third working specimen.

[0101] In this embodiment, the inventors further considered that during the welding manufacturing of a product project, it is necessary to analyze and determine whether the actual welding conditions have been verified by the working specimen or whether they can be covered by other verified working specimens. At this time, it is still necessary for technicians to manually check the previous paper-based verification reports and perform analysis. Due to differences in individual experience, there is a risk of analysis errors leading to redundant specimen verification. However, by establishing a preset working specimen database in this application and obtaining the input information of the third working specimen, it is possible to simply, automatically, quickly, and accurately determine whether there are one or more second working specimens (i.e., target second working specimens) that can cover the third working specimen (specifically, the basic welding information, preset verification purpose, and preset coverage of the target second working specimen include the input information) based on each verified second working specimen. This eliminates the tedious steps of manual verification and reduces the risk of redundant specimen verification to a certain extent.

[0102] It is understandable that when it is determined that no second working specimen can be used as the target working specimen, it means that the working condition to be analyzed cannot be covered by any second working specimen. Therefore, a feedback signal indicating that no relevant information was found can be output or the result of the search failure can be displayed through the display module so that the user can subsequently verify the third working specimen.

[0103] Please refer to Figure 4 , Figure 4 This is a schematic diagram of a system for determining the coverage area of ​​a welding work specimen provided by the present invention.

[0104] The system for determining the coverage of welding test specimens includes:

[0105] Acquisition unit 21 is used to acquire the verification purpose and key information of the first working specimen whose coverage area is to be determined;

[0106] Search unit 22 is used to search in a preset working specimen database based on verification purpose and key information. The preset working specimen database includes multiple second working specimens with verified coverage. Each second working specimen includes basic welding information, preset verification purpose and preset coverage corresponding to the preset verification purpose. The preset coverage is predetermined based on the basic welding information and the stored preset welding standard specifications corresponding to the preset verification purpose.

[0107] Judgment unit 23 is used to determine whether there is a selected second working specimen in each second working specimen with a preset verification purpose including the verification purpose and basic welding information including key information; if so, trigger coverage determination unit 24.
