Based on any of the above embodiments, in this embodiment, fig. 2 is a schematic diagram of a welding process design module in the welding process information processing system of the present invention, and as shown in fig. 2, the welding process design module includes: a data input unit 1011 and a process data recommendation unit 1012.
The data input unit 1011 is used for receiving welding process condition information of a welding item.
In the present embodiment, the welding process condition information of the welding item includes parent material information, joint form, and welding method.
The base metal is a material to be welded in the welding process, such as angle steel, channel steel, I-steel and the like. The parent metal information includes the steel number of the parent metal, the thickness of the parent metal, and the like.
The joint form is the form of a welded joint. Common forms of joints include: butt joints, T-joints, angle joints, and lap joints. The joint form is mainly determined according to the form, stress state, use condition and construction condition of the welding member, and the invention only receives the information of the joint form in the welding item, and does not relate to how to determine the joint form of the welding item.
The welding method is the method adopted in the welding process. The welding methods include fusion welding, pressure welding and brazing. Fusion welding includes arc welding, gas welding, thermite welding, electroslag welding, electron beam welding, laser welding; pressure welding comprises resistance spot seam welding, resistance butt welding, ultrasonic welding, explosion welding, diffusion welding, friction welding and high-frequency welding; the brazing includes flame brazing, induction brazing, furnace brazing, salt solution brazing and electron beam brazing. The above welding method can be further subdivided.
The particular welding method may be indicated numerically, in accordance with common general knowledge in the art. The welding method as 135 represents consumable electrode active gas shielded welding; the 141 welding method represents non-consumable inert gas welding.
An example of welding process condition information for a welding project is: ISO 15614-1135P BW 1.4t12 ml nb.
The ISO15614-1 indicates that the standard adopted by the welding project is the part 1 sub-standard of the 15614 standard series in the ISO international standard, 135 is the code of the welding method, BW indicates that the joint form is butt joint, 1.4 indicates that the welding project refers to the sequence classification number of materials in the ISO 15608 standard, t12 indicates that the plate thickness is 12mm, m1 indicates a multi-layer or multi-channel welding seam, and nb indicates that no back protection exists.
The welding process condition information of the welding item may be proposed by the user and input to the data input unit 1011. The data input unit 1011 may be a data input device such as a keyboard, a mouse, a camera, a scanner, a light pen, a handwriting input board, a cd-rom, a hard disk connection port, and a usb disk connection port, and is not particularly limited in the present invention.
The process data recommending unit 1012 is configured to search candidate process data of the welding item according to the welding process condition information of the welding item, and determine welding process data of the welding item according to the candidate process data.
Generally, the welding process condition information of the welding project is mainly a frame description of the welding process, and specific process data is lacked. The process data recommendation unit 1012 may generate candidate process data based on the historical welding data in combination with the welding process condition information of the welding project.
In the present embodiment, the historical welding data is data of welding items previously processed by the welding process information processing system. The welding data includes the whole process data of the welding project, such as welding process condition information, process data of the welding project, and the like. The historical welding data is stored in the database module 103 and can be inquired and compared by the process data recommendation unit 1012.
The process data recommendation unit 1012 searches the historical welding data for the welding data corresponding to the welding process condition information after obtaining the welding process condition information from the data input unit 1011, and obtains candidate process data according to the search result.
For example, in one embodiment, the welding process condition information for the welding project is: ISO 15614-1135P BW 1.4t12 ml nb.
The process data recommendation unit 1012 searches the historical welding data according to the welding process condition information to obtain the following two data:
the welding method A comprises the following steps:
adopts multilayer and multi-pass welding seams, the welding seams are in a single-side welding and double-side forming mode, and the welding bead layout is 3 layers and 4 passes.
The welding parameters include: f1 welding pass, welding current is 180A, welding voltage is 21.5V, and welding speed is 6.5 mm/s; f2 welding pass, the welding current is 230A, the welding voltage is 22.5V, and the welding speed is 5.0 mm/s; f3 welding pass, wherein the welding current is 220A, the welding voltage is 22V, and the welding speed is 6.5 mm/s; f4 pass, welding current 220A, welding voltage 22.5V, and welding speed 6 mm/s.
And a welding method B:
the double-sided welding mode is adopted, and the welding bead layout is 4 layers and 4 tracks.
The welding parameters include: f1 welding pass, welding current is 180A, welding voltage is 21.5V, and welding speed is 6.0 mm/s; f2 welding pass, welding current is 200A, welding voltage is 21.5V, and welding speed is 5.5 mm/s; f3 welding pass, welding current is 200A, welding voltage is 22V, and welding speed is 6 mm/s; in the F4 pass, the welding current was 220A, the welding voltage was 22V, the welding speed was 3.5mm/s, and the swing was performed during welding.
The above two candidate process data are only used as examples, and those skilled in the art will understand that the number of the available candidate process data may be varied in practical applications, which is not limited in the present invention.
The two candidate process data mainly comprise welding parameter information and welding bead layout information. Those skilled in the art will appreciate that in practical applications, the candidate process data may also include other types of data, such as material properties of the welded joint after welding, e.g., weld joint micro-topography, weld joint mechanical properties.
When the number of the candidate process data is more than one, the finally selected process data can be determined according to the correlation between the candidate process data and the welding process condition information in the welding project; or secondary screening is carried out on the candidate process data according to the unchangeable elements specified by the customer, so as to determine the finally selected process data. Optionally, when the process data recommendation unit 1012 searches for the welding data corresponding to the welding process condition information from the historical welding data, the welding data weakly related to the welding process condition information may be searched for.
In practical applications there is the possibility that: a certain welding project is novel, and historical welding data consistent with the welding process condition information cannot be found in the database module. At this time, the welding data weakly related to the welding process condition information can be searched, and candidate process data can be obtained from the search result.
The weak correlation means that the similarity with the welding process condition information of the welding item is greater than a specified threshold. For example, in the welding process condition information of the welding item, the thickness of the base material is 11mm, and the thickness of the base material, which is weakly related thereto, is 10 mm. As another example, in the welding process condition information of the welding item, the welding method is 131 welding method (mig), and the welding method weakly related thereto is 141 welding method (non-mig).
Optionally, when searching for the welding process condition information in the historical welding data, the process data recommendation unit 1012 may directly provide the welding process data to the welding item if the welding process data that matches the welding process condition information and is evaluated by the welding process is already stored in the historical welding data. The subsequent operation of evaluating the welding process on the welding process data is not required.
The welding process information processing system provided by the invention searches the welding process data from the historical welding data based on the welding process condition information of the welding project, can realize intelligent recommendation of the welding process data, can save labor cost and time cost, and improves the welding efficiency.
Based on any one of the above embodiments, in this embodiment, the welding process design module further includes: and the early warning unit is used for checking the welding process condition information of the welding project and sending warning information when the welding process condition information triggers a limit condition.
In the previous embodiments, it has been mentioned that the welding process condition information of the welding project is generally provided by the user, and the welding process condition information provided by the user may not meet the objective rule or have great difficulty due to limitations in experience, professional knowledge and the like. The early warning unit can judge the feasibility of the welding process condition information of the welding project according to historical welding data or related technical standards, and sends out warning information when the feasibility is not high (such as triggering limit conditions). The limit condition can be obtained according to historical welding data or technical standards.
For example, when a user entrusts to launch the project of ISO 15614-1135P BW 1.4t0.6 ml nb, the plate thickness level is extremely low (0.6mm), the welding method is difficult to realize by adopting 135, and the early warning unit sends out warning information.
After receiving the warning message, the user may perform a subsequent process, such as terminating the subsequent process, or modifying the welding process condition information.
Optionally, after the warning unit sends the warning information, a suggestion scheme may be generated according to the historical welding data for the user to refer to.
The welding process information processing system provided by the invention can find unreasonable welding process condition information in time by pre-judging the welding process condition information of the welding project proposed by a user, thereby saving subsequent unnecessary processes and saving calculation resources and time resources.
Based on any embodiment, in this embodiment, fig. 3 is a schematic diagram of a welding process evaluation module in the welding process information processing system of the present invention, and as shown in fig. 3, the welding process evaluation module includes: an evaluation logic determination unit 1021, an evaluation unit 1022, and an evaluation result output unit 1023.
The evaluation logic determination unit 1021 is used to determine the evaluation logic of the welding item.
In this embodiment, the evaluation logic includes criteria upon which the welding process is evaluated, the set evaluation step, and the determined standard requirement value. Specifically, the standard may be a material standard corresponding to a material used for welding, a welding specification standard, or the like. The assessment steps are steps in the assessment process of the welding process, and the assessment steps corresponding to different welding items may be different, so that the assessment steps need to be determined according to the specific content of the welding items and in combination with industry knowledge or the standards. The standard required values are used to judge the quality of the welding process and can be determined from industry knowledge, the standard or historical welding data.
For example, the customer entrusts the welding project ISO 15614-1135P BW 1.4t12 ml nb, the evaluation logic determination unit 1021 selects to execute the ISO15614-1 standard according to the project content, and the evaluation steps determined according to the standard requirement include: welding, nondestructive testing (2 items including magnetic powder testing and ray testing), destructive testing (macroscopic metallography, tensile test, bending test, hardness test, impact test and the like). The standard requirement values of all the evaluation steps are different, and if the welding step requires that the welding appearance cannot have defects which cannot be allowed by standards such as cavities and welding beading; the nondestructive testing step requires that the defect features specified by the standard cannot appear; the destructive testing step requires that the destructive testing value not be below the minimum value specified by the standard.
It should be noted that the criteria, evaluation steps, criteria requirements, etc. in the evaluation logic may vary. If a certain national standard is updated, the evaluation steps, standard requirement values and the like determined according to the standard can be correspondingly updated. For another example, as the historical weld data increases, a new limit condition is determined, and the corresponding standard requirement value is updated accordingly.
The evaluation unit 1022 is used to perform welding process evaluation on the weld produced according to the welding process data according to the evaluation logic.
The previous welding process design module 101 has determined welding process data based on the welding process condition information for the welding project. A weld can be made according to the welding process data. The evaluation unit 1022 may evaluate the welding process for the weld based on the evaluation logic determined by the evaluation logic determination unit 1021.
Still taking the welding project ISO 15614-1135P BW 1.4t12 ml nb as an example, firstly, forming a welding part meeting the appearance and parameter specifications according to the welding process data determined by the welding process design module 101; then, performing nondestructive detection on the welding part, such as nondestructive detection in two forms of magnetic powder detection and ray detection; finally, performing destructive testing on the welding piece, such as adopting destructive testing modes of macroscopic metallographic testing, stretching experiments, bending experiments, hardness experiments, impact experiments and the like.
The welding process evaluation performed by the evaluation unit 1022 has a plurality of evaluation steps, wherein the result of any one of the evaluation steps is compared with the standard requirement value, and if the result of any one of the evaluation steps does not meet the standard requirement value, the judgment of waste is required, and instructions such as termination and repair are executed. If the process is stopped, the process cannot form a reasonable and effective product, and if the process is repaired, the process needs to be tested again for verification. When all the flows are finished and meet the standard requirement value, the process data designed by the welding process design module is reasonable, and a process rule can be formed.
The evaluation result output unit 1023 is used to output the evaluation result.
The evaluation unit 1022 has two possibilities for evaluating the welding process of the welding part, when the result does not accord with the standard required value, the evaluation result output unit 1023 outputs the prompt information of the termination or the component prompt information; when the result is in accordance with all the standard requirement values, the evaluation result output unit 1023 outputs the process rules to the outside. Obviously, the process is reasonable and can be applied to practice.
The welding process information processing system provided by the invention evaluates the welding process data determined by the welding process design module through the welding process evaluation module to determine whether the welding process data meets the requirements, so that the accuracy of the welding process data determined by the welding process design module is ensured, and the welding quality is ensured.
Based on any one of the above embodiments, in this embodiment, the database module includes: a parent metal database, a groove form diagram library, a welding program parameter database, a welding material database, a welding process evaluation report database and an auxiliary library.
Specifically, the parent metal database is used for storing information of parent metal groups, processing states, performance indexes, manufacturers and the like;
the groove form gallery is used for storing a groove form picture;
the welding program parameter database is used for storing welding program parameters;
the welding material database is used for storing information of welding material manufacturers, batches, verification data, performance, stability and the like of welding materials;
the welding process evaluation report database is used for storing welding process evaluation reports;
the auxiliary library is used for storing stray contents such as tools, software logs, customer information and the like which are convenient for the comparative analysis of the process evaluation information.

Based on any of the above embodiments, in this embodiment, fig. 4 is a second schematic diagram of the welding process information processing system provided by the present invention, and the welding process information processing system further includes: and an evaluation module 104 for analyzing the welding process assessment results.
After the welding process assessment is completed, the evaluation module may perform further analysis processing on the welding process. For example, the data for a welding item that has currently been rated by the process may be compared to previously stored data for a welding item that has been rated by the process, and if there are identical or similar welding items, the process data for the two may be compared to form a broader range of process data. As can be seen from the data of a plurality of welding items, when welding 12mm sheet materials, the welding joint has the problem of poor fusion when the welding current is lower than 160A; when the welding current is more than 260A, the problems of widmannstatten structures or element burning loss, cracks and the like of the welding microstructure can occur. Thus, integrating data for a plurality of welding projects can yield: when a 12mm plate is welded, the welding current which can be borne by the welding wire ranges from 160A to 260A.
For another example, when a code is used to represent a welding item, there is a problem that the code of different welding items is the same, but the information on the specific welding process conditions is different, because the meaning that the code can express is limited. The evaluation module can distinguish the data of the welding projects to form a plurality of items of parallel information, so that later retrieval and analysis are facilitated.
For another example, the standard requirement values are derived from the existing data of the welding project evaluated by the process, and are used in the subsequent process evaluation.
The welding process information processing system provided by the invention can further mine the internal relation of the welding data through analyzing the evaluation result of the welding process, realizes the updating of various types of data such as welding parameters, standard required values and the like, and is beneficial to further optimizing the welding process data.

And a welding training and examination module 105 for performing welding training and welding examination on a welder.
In a database module of the welding process information processing system, standards according to which the welding process is evaluated, the set evaluation steps, and the determined standard requirement values are stored.
