Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel pipeline welding control, and in particular to a stainless steel pipeline welding control system based on a large model. Background Art

[0002] Stainless steel pipes are widely used in life, so the quality of stainless steel pipes is particularly critical. Therefore, the process parameters when welding stainless steel pipes need to be strictly controlled to ensure the application quality of stainless steel pipes. By analyzing the corresponding welding routes of stainless steel pipes, and then matching the corresponding welding parameters for stainless steel pipes based on large model technology, high-quality welding of stainless steel pipes can be intelligently controlled.

[0003] Prior art, such as the invention patent application disclosed in publication number CN108453349B, discloses a stainless steel pipe welding method for welding stainless steel pipes with grooves. The method uses a stainless steel flux-cored wire for welding, with the pipe circumferential direction as the welding direction. The welding process includes the following steps: welding the base layer using argon arc welding combined with an internal filler wire, with the welding gun moving within the groove in a lateral swing between the two sides of the groove along the welding direction to form the base layer; then welding the filling layer using gas shielded welding, with the welding gun moving within the groove in a lateral swing between the two sides of the groove along the welding direction to form the filling layer; and then welding the capping layer using gas shielded welding, with the welding gun moving within the groove in a lateral swing between the two sides of the groove along the welding direction to form the capping layer. The present invention uses a stainless steel flux-cored wire and argon arc welding to complete the base layer welding. Argon is not filled on the back of the weld, reducing argon waste. Gas shielded welding is used for the filling and capping layers, reducing the number of weld joints between the filling and capping layers.

[0004] With respect to the above scheme, there are the following technical problems: the above invention is mainly for welding between stainless steel pipes with grooves, using stainless steel flux-cored wire for welding in the circumferential direction of the pipe. The basic connection form corresponding to the stainless steel pipe is not analyzed, and the line analysis based on the form of the basic connection of the stainless steel pipe cannot be performed. The efficient pipe connection corresponding to the stainless steel pipe cannot be obtained, which reduces the adaptability of the pipe connection. The welding method of each node under the stainless steel pipe line connection is not analyzed. Based on the conditions of the corresponding welding method of the stainless steel pipe, the corresponding optimal welding parameters cannot be obtained to achieve the optimal welding of the stainless steel pipe, and the intelligent welding control of the stainless steel pipe is not achieved. At the same time, the corresponding welding effect of the stainless steel pipe is not analyzed and evaluated, and timely and efficient welding control and regulation cannot be performed when the welding effect of the stainless steel pipe is not good, which reduces the welding quality of the stainless steel pipe and increases the pipe welding scrap rate.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1 As shown, a stainless steel pipeline welding control system based on a large model includes a pipeline welding route planning module, a welding parameter control and analysis module, a pipeline welding monitoring module, an early warning terminal and a database.

[0018] The welding parameter control and analysis module is connected to the pipeline welding route planning module and the pipeline welding monitoring module respectively. The pipeline welding monitoring module is connected to the early warning terminal and the database respectively. The database is connected to the pipeline welding route planning module and the welding parameter control and analysis module respectively.

[0019] The pipeline welding route planning module is used to obtain the basic information of the corresponding application site of the stainless steel pipeline, and then analyze the corresponding welding connection form of the stainless steel pipeline. Based on the analysis of the connection form, the corresponding welding connection route of the stainless steel pipeline is analyzed.

[0020] It should be noted that the connection form: straight straight bend straight bend straight or straight bend bend straight straight bend, etc.; the sequential connection route is: 1 straight pipe welding - straight pipe welding - straight elbow pipe lower connection - straight pipe connection - elbow pipe connection; 2 straight elbow pipe lower connection - straight pipe connection - elbow pipe connection - straight pipe welding - straight pipe welding, etc.

[0021] It should be noted that the basic information includes medium flow data, spatial layout data and stress distribution data; medium flow data is obtained using ultrasonic Doppler flow meters and fiber optic spectrometers; spatial layout data is obtained using a three-dimensional laser scanner and BIM software combined with a total station; stress distribution data is obtained using strain gauges and accelerometers; medium flow data includes flow velocity or corrosion rate, etc.; spatial layout data includes safety positions or maintenance space volumes, etc.; stress distribution data includes thermal expansion or vibration frequency, etc.

[0022] As an optional implementation, the analysis obtains the corresponding welding connection form of the stainless steel pipeline. The specific analysis process is as follows: obtain the basic information corresponding to the stainless steel pipeline, including medium flow data, spatial layout data and stress distribution data, compare the medium flow data corresponding to the stainless steel pipeline with the medium flow data corresponding to the historical pipeline welding forms stored in the database, and at the same time compare the spatial layout data and stress distribution data corresponding to the stainless steel pipeline with the spatial layout data and stress distribution data corresponding to the historical pipeline welding forms stored in the database. When the medium flow data corresponding to the stainless steel pipeline is the same as the medium flow data corresponding to a historical pipeline welding form stored in the database, and the spatial layout data and stress distribution data corresponding to the stainless steel pipeline are the same as the spatial layout data and stress distribution data corresponding to the historical pipeline welding form stored in the database, then the pipeline welding form is used as the corresponding welding connection form of the stainless steel pipeline.

[0023] As an optional implementation, the analysis obtains the connection route corresponding to the welding of the stainless steel pipeline. The specific analysis process is as follows: based on the connection form of the corresponding welding of the stainless steel pipeline, the corresponding form welding is performed on this basis, and the nodes corresponding to the welding of the pipeline are extracted according to the connection form diagram of the pipeline and the number of pipe bodies.

[0024] The welding groove data and welding shape data of each node corresponding to the stainless steel pipeline are compared with the reference welding groove data and reference welding shape data under each reference route stored in the database. If the welding groove data corresponding to a node of the stainless steel pipeline is the same as the reference welding groove data of a reference route stored in the database, and the reference welding shape data of the node is also the same as the reference welding shape data of the reference route stored in the database, then the reference route is used as the connection route corresponding to the welding of the current stainless steel pipeline.

[0025] If the welding groove data of a node corresponding to the stainless steel pipeline is the same as the reference welding groove data of a reference route stored in the database, but the reference welding shape data of the node is different from the reference welding shape data of the reference route stored in the database, then the welding sequence corresponding to the welding groove data in the reference route is taken, and the reference welding shape data corresponding to the node is compared with the reference welding shape data of the remaining reference routes. If the reference welding shape data corresponding to the node is the same as the reference welding shape data of the remaining reference routes, then the welding sequence corresponding to the welding shape data in the reference route is taken, and based on the size of the welding sequence corresponding to the welding groove data and the welding shape data, welding routes are composed in descending order, so as to obtain the corresponding welding connection route of the stainless steel pipeline through analysis.

[0026] It should be noted that if the welding groove data corresponding to a node of the stainless steel pipeline is different from the reference welding groove data of a reference route stored in the database, but the reference welding shape data of the node is the same as the reference welding shape data of the reference route stored in the database, the method of analyzing the connection route is the same as the analysis method when the welding groove data is the same but the welding shape data is different, and no further details will be given here.

[0027] It should also be noted that the reference welding groove data and reference welding shape data are set by professional welding personnel; the reference welding groove data and reference welding shape data are reference values used to determine the corresponding welding connection route of the current stainless steel pipeline.

[0028] It should be noted that the welding groove data includes the groove angle or blunt edge size, etc.; the welding shape data includes the shape type, etc.

[0029] Obtain the basic information of the corresponding application site of the stainless steel pipe, analyze the corresponding welding connection form of the stainless steel pipe, and on the basis of the analysis of the connection form, analyze the corresponding welding connection route of the stainless steel pipe, and then realize the efficient welding of the stainless steel pipe. Taking planned pipeline welding can make the welding of the stainless steel pipe more efficient and smooth.

[0030] The welding parameter control analysis module is used to analyze the welding method of each node under the corresponding connection route of the stainless steel pipeline according to the corresponding welding connection route of the stainless steel pipeline, and based on the analyzed welding method, analyze the control parameters of the welding of each node of the stainless steel pipeline.

[0031] It should be noted that element data includes chromium, nickel or carbon, etc.; mechanical property data includes hardness or toughness, etc., and material data is obtained from the specification material information corresponding to the stainless steel pipe.

[0032] It should be noted that if the element data and mechanical property data corresponding to the stainless steel pipeline are not within the reference data of the same welding method, the reference welding quality coefficient threshold of the welding method is obtained based on the comparison, and the welding method with a higher reference welding quality coefficient threshold is used as the welding method under the corresponding connection route of the current stainless steel pipeline.

[0033] It should also be noted that the reference element data and reference mechanical property data are set by professional welding personnel; the reference element data and reference mechanical property data are reference values used to determine the welding method of each node under the corresponding connection line of the stainless steel pipeline.

[0034] As an optional implementation method, the analysis obtains the welding method of each node under the corresponding connection line of the stainless steel pipe. The specific analysis process is as follows: obtain the material data corresponding to the stainless steel pipe under the connection line, including element data and mechanical property data, and compare the element data of the front-end stainless steel pipe and the rear-end stainless steel pipe under the corresponding node of the stainless steel pipe with the reference element data corresponding to each welding method stored in the database. At the same time, compare the mechanical property data of the front-end stainless steel pipe and the rear-end stainless steel pipe under the corresponding node of the stainless steel pipe with the reference mechanical property data corresponding to each welding method stored in the database. When the element data and mechanical property data of the front-end stainless steel pipe and the rear-end stainless steel pipe under the corresponding node of the stainless steel pipe are the same as the reference element data and reference mechanical property data corresponding to a certain welding method, then the welding method is used as the welding method of the first section node of the stainless steel pipe under the connection line. And so on, the welding method of each node under the corresponding connection line of the stainless steel pipe is obtained.

[0035] As an optional implementation method, the analysis obtains the control parameters for welding of each node corresponding to the stainless steel pipeline. The specific analysis process is as follows: according to the welding method of each node under the corresponding connection line of the stainless steel pipeline, the historical reference risk value and historical reference safety value of the welding method of each node corresponding to the stainless steel pipeline are obtained from the database, and the reference welding safety interval is obtained based on the historical reference risk value and historical reference safety value.

[0036] And obtain the wall thickness of each welding node corresponding to the stainless steel pipeline, and compare the wall thickness of each welding node corresponding to the stainless steel pipeline with the reference welding safety interval of the wall thickness of each node corresponding to the historical welding of the stainless steel pipeline. If the wall thickness of a certain welding node of the stainless steel pipeline is within the reference welding safety interval of the wall thickness of a certain node corresponding to the historical welding of the stainless steel pipeline, then the welding control parameters corresponding to the wall thickness of the node within the welding safety interval are used as the welding control parameters of the first section node of the stainless steel pipeline. By comparing and analogizing, the control parameters of the welding of each node corresponding to the stainless steel pipeline are obtained.

[0037] It should be noted that the control parameters include welding current, voltage, speed and gas flow, etc.

[0038] By analyzing the welding method of each node under the corresponding connection line of the stainless steel pipeline, and based on the analyzed welding method, the control parameters of the welding of each node of the stainless steel pipeline corresponding to the analysis are obtained, so as to achieve effective control of the welding quality of the stainless steel pipeline, thereby improving the efficiency of stainless steel pipeline welding and ensuring the welding stability of the stainless steel pipeline welding quality.

[0039] The pipeline welding monitoring module is used to weld stainless steel pipelines based on the analyzed control parameters, and at the same time monitor the welding of stainless steel pipelines, obtain the welding data of each node welding of the stainless steel pipeline, and then judge the welding quality of the corresponding welding of the stainless steel pipeline, and analyze the control adjustment of the corresponding welding of the stainless steel pipeline.

[0040] It should be noted that a camera is used to obtain welding images of each welding node of the stainless steel pipe, and then the oxidation color is extracted from the welding image. The oxidation color of the stainless steel pipe is silvery white or golden yellow; an angle ruler is used to obtain the angular deformation of each welding node of the stainless steel pipe, and the angular deformation is ≤3°; a roughness meter is used to obtain the weld roughness of each welding node of the stainless steel pipe, and the weld roughness is ≤0.8μm.

[0041] As an optional implementation, the welding data includes oxidation color, angular deformation and weld roughness.

[0042] As an optional implementation manner, the specific judgment process of judging the welding quality of the corresponding welding of the stainless steel pipe is as follows: the welding data of each node of the corresponding welding of the stainless steel pipe is imported into the stainless steel pipe welding quality judgment model, and then the quality assessment result value of each node of the corresponding welding of the stainless steel pipe is obtained by analysis. If the quality assessment result value of a certain node of the stainless steel pipe welding is 1, then the welding quality of the corresponding welding node of the stainless steel pipe is judged to be qualified; if the quality assessment result value of a certain node of the stainless steel pipe welding is 0, then the welding quality of the corresponding welding node of the stainless steel pipe is judged to be unqualified, and further welding problem analysis is performed on the phenomenon of unqualified welding nodes of the stainless steel pipe, so as to judge the welding quality of the corresponding welding of the stainless steel pipe.

[0043] As an optional implementation, the analysis obtains the quality assessment result value of each welding node of the stainless steel pipeline. The specific analysis process is as follows: Through the stainless steel pipeline welding quality evaluation model: where β d is the quality assessment result value of the dth node of the stainless steel pipeline, Y′ is the reference oxidation color of the stainless steel pipeline, J′ is the reference angular deformation of the stainless steel pipeline, H′ is the reference weld roughness of the stainless steel pipeline, and Y d is the oxidation color of the dth node of the stainless steel pipe, J d is the angular deformation of the dth node of the stainless steel pipe, H d is the weld roughness of the stainless steel pipeline corresponding to the dth node, R sets the reference quality value of the stainless steel pipeline, d is the number of each node, d = 1, 2, ..., ..., n, n is any integer greater than 2.

[0044] It should be noted that the reference oxidation color, reference angular deformation, reference weld roughness and reference quality value are set by professional welding personnel; the reference quality value is a reference value used to judge the welding quality of the corresponding welding of stainless steel pipes. The setting process of the reference oxidation color, reference angular deformation and reference weld roughness is consistent with that of the reference quality value, so they are not repeated here.

[0045] It should be noted that the reference control parameter data is set by professional welding personnel. The reference control parameter data is a reference value used to determine whether the control parameter data corresponding to the current stainless steel pipeline is compliant; the reference control data includes the welding gun angle and nozzle angle, welding current and voltage, number of welding layers and oscillation frequency, etc.

[0046] As an optional implementation, the analysis obtains control adjustments for the corresponding welding of the stainless steel pipeline. The specific analysis process is as follows: based on the phase difference between the data in the quality assessment result value of each node corresponding to the stainless steel pipeline and the reference data, if the oxidation color data in the quality assessment result value of a node corresponding to the stainless steel pipeline shows a large difference from the reference oxidation color data, then the control parameter data affecting the oxidation color is extracted from the control parameters of the corresponding welding of the stainless steel pipeline, and the extracted control parameter data is compared with the reference control parameter data stored in the database to obtain the phase difference between the control parameter data, and then the difference is reduced by one bit on the basis of the obtained phase difference so that the control parameter data is smaller than the reference control parameter data, and the reduced control parameter data is used as the control adjustment for the corresponding welding of the stainless steel pipeline. In this way, the welding adjustment for a node of the stainless steel pipeline with angular deformation and weld roughness quality is obtained by analogy, and the control adjustment for the corresponding welding of the stainless steel pipeline is obtained by analysis.

[0047] Based on the analyzed control parameters, the stainless steel pipe is welded, and the welding of the stainless steel pipe is monitored at the same time to obtain the welding data of the corresponding nodes of the stainless steel pipe, and then the welding quality of the corresponding welding of the stainless steel pipe is judged, and the control adjustment of the corresponding welding of the stainless steel pipe is analyzed to ensure the welding quality of the stainless steel pipe, reduce the scrap rate of the stainless steel pipe, and avoid the fault tolerance of frequent stainless steel pipe welding quality problems.

[0048] The database is used to store basic information, reference welding groove data, reference welding shape data, material data, reference element data, reference mechanical property data, historical reference critical values, historical reference safety values, wall thickness and welding data.

[0049] The early warning terminal is used to issue an early warning prompt when the welding quality of a certain node of the stainless steel pipeline is unqualified.

[0050] The embodiment of the present invention analyzes the welding morphology of the stainless steel pipe, and then analyzes the corresponding connection line of the stainless steel pipe based on the corresponding welding morphology of the stainless steel pipe, implements planned pipeline welding, and analyzes the corresponding welding method and control parameters of the stainless steel pipe, and performs high-quality welding parameter control of the stainless steel pipe, thereby ensuring the welding quality of the stainless steel pipe. At the same time, based on the control adjustment of the corresponding welding of the stainless steel pipe, the stainless steel pipe welding waste rate is further reduced, and the fault tolerance of frequent stainless steel pipe welding quality problems is avoided, thereby achieving effective control of the stainless steel pipe welding quality.

Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner.
