[0035] A protective cover 20 is fixedly connected to the surface of the welding device 3, and an observation window 21 is installed on one side of the protective cover 20. When the welding device 3 welds the pipeline, the protective cover 20 is used to avoid glare to the personnel and observe through the observation window 21. The protective cover 20 has an anti-glare effect on the personnel, thereby effectively improving the work safety of the personnel. A smoking device 22 is installed on one side of the welding device 3. Two groups of smoking pipes 23 are connected to the upper surface of the smoking device 22.

A heating wire 25 is fixedly connected to the upper surface of the heating device 24. A weld gap detector 31 is slidably connected to one side of the heating device 24. Special processes require that the pipeline be preheated by the heating wire 25 when connected. The heating device 24 achieves the effect of further improving the welding efficiency of the device.

[0036] A telescopic rod is installed on one side of the pipe mouth docking tooling 26, and a magnifying display screen 27 is fixedly connected to the output end of the telescopic rod. The pipe mouth docking work is observed through the magnifying display screen 27, and the magnifying display screen 27 plays a role in improving the pipe mouth docking accuracy. A turntable is fixedly connected to the upper surface of the base 4, and the upper surface of the turntable is fixedly connected to the Y-shaped bracket 5. The turntable drives the Y-shaped bracket 5 to rotate through the base 4, and the turntable plays a better supporting role for the Y-shaped bracket 5. The base 4 and the turntable can be moved in both height and horizontal directions. A plurality of rollers are connected to the surface of the Y-shaped bracket 5 for uniform rotation. The pipeline slides from the surface of the Y-shaped bracket 5 with the help of the rollers, and the rollers achieve the effect of reducing the friction of the Y-shaped bracket 5 itself.

[0037] Working principle: When it is necessary to weld the pipes of the pipeline system in the construction of a cruise ship, the pipes are first conveyed through the conveyor belt 1, and are grabbed by the first mechanical arm 2 to the surface of the Y-shaped bracket 5. The pipes can be rotated and moved horizontally with the help of the turntable and the base 4. The turntable plays a better role in supporting the Y-shaped bracket 5. The pipe mouths of the special-shaped pipes are connected, and the pipes to be welded are connected through the pipe mouth connection tooling 26 with the help of the telescopic rod using the enlarged display screen 27. The enlarged display screen 27 plays a role in improving the accuracy of the pipe mouth connection. Then, the weld gap of the connected pipes to be welded is detected by the weld gap detector 31. The weld gap detector is used to detect whether the group gap and groove data meet the welding standards. When the detection meets the standards, the pipeline is then inflated through the inflation pipe 17. The inflation pipe 17 uses the delivery pipe 14 through the argon distribution device 15 to transport argon with the help of the argon tank 13. The argon tank 13 can prevent oxidation at the weld in the pipeline. During the argon filling process, the argon concentration detector 18 can be used to detect the argon gas on the docked pipeline. After the argon concentration detector 18 detects that the argon concentration in the pipeline to be welded reaches the argon concentration required for welding the pipeline to be welded, the argon filling process is completed, and then welding is prepared. When some special-shaped pipelines or stainless steel pipelines with special process requirements are connected, the heating device 24 can be started. The heating device 24 can further improve the welding efficiency of the device. The heating device 24 heats the heating wire 25, thereby preheating the special process pipeline. After preheating is completed, it enters the protective cover 20 through the Y-shaped bracket 5. The protective cover 20 has an anti-glare effect on personnel. Welding is performed through the welding device 3, and personnel can observe through the observation window 21. At this time, the smoking device is started Device 22, the smoking device 22 plays a role in preventing surrounding air pollution. The hot smoke in the protective cover 20 is extracted by means of the smoking pipe 23. After welding is completed, it is transported again from the roller arc surface through the Y-shaped bracket 5. The roller achieves the effect of reducing the friction of the Y-shaped bracket 5 itself. When it is transported to one side of the grinding device 6, the surface of the welded pipeline is polished by the sand belt. After grinding, it moves to the surface of the transport vehicle 9. The transport vehicle 9 moves the pipeline to the lead room 7 through the track 8. The pipeline is inspected by the flaw detection device 10 in the lead room 7. After the inspection is completed, the transport vehicle 9 drives the pipeline out, and then the weld is inspected again by the ultrasonic weld detection device 29. The inspection data is transmitted through the data transmission module 30. When the pipeline needs to be repaired, it is reminded by the alarm light 19. The alarm light 19 plays a role in improving the response speed of the flaw detection device 10 or the ultrasonic weld detection device 29. The pipeline that does not need to be repaired is finally moved to the conveyor belt 12 by the second mechanical arm 11, and finally transported by the conveyor belt 12.

[0038] It should be noted that, in this article, relational terms such as the first robotic arm and the second robotic arm are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0039] This tool uses two independent weld inspection technologies: lead room flaw detection film and ultrasonic weld inspection. These two inspection methods operate in parallel, providing customers with flexible options to adapt to different inspection needs and standards.

[0040] In addition, in addition to welding work on straight pipe sections, it is also suitable for combining with existing technologies to carry out docking and welding work on bent pipes. Specifically, the flexibility and multifunctional design of the tooling allow it to be combined with existing pipeline construction technologies to adapt to pipes of different shapes and specifications, including but not limited to bent pipes. First, the conveyor belt 1 and the first robotic arm 2 in the tooling can be used in conjunction to accurately locate and grasp the bent pipe to ensure accurate docking with the straight pipe section or other bent pipes. The telescopic rod and magnified display screen 27 equipped with the pipe mouth docking tooling 26 can further assist the operator in making fine adjustments to ensure the docking accuracy of the bent pipe.

[0041] Secondly, the welding device 3 model PPBW-24 has the ability to adapt to different pipe shapes. The protective cover 20 and observation window 21 equipped therewith can protect the operator during the welding process and provide a clear line of sight to monitor the welding quality. In addition, the fume extraction device 22 and the heating device 24 can be used to remove the fume generated during the welding process and preheat the pipe respectively to meet the requirements of a specific welding process.

[0042] Furthermore, the argon distribution system in the tooling, including the argon tank 13, the delivery pipe 14, the argon distribution device 15 and the welding gun 16, can provide necessary argon protection for the elbow welding to prevent oxidation of the welding area.

[0043] Finally, the flaw detection device 10 or the ultrasonic weld detection device 29 can perform strict inspection on the weld after the elbow is welded to ensure that the welding quality meets the standard. Through the data transmission module 30 and the alarm light 19, real-time monitoring and feedback of the welding quality can be achieved.

[0044] It is worth noting that lead room flaw detection filming and ultrasonic weld inspection are used as two parallel inspection methods in this tool. This means that users can choose one or both methods to use in parallel according to specific welding conditions and quality requirements to obtain the most comprehensive weld quality assessment. " In addition to traditional physical detection methods, it is also possible to integrate advanced digital technology to achieve digital flaw detection operations by comparing big data. The following is a description of digital flaw detection operations and their technical means: Digital flaw detection is a non-destructive testing method based on computer technology and data analysis. It collects and analyzes the data generated during the flaw detection process and uses big data comparison technology to identify and evaluate possible defects in the pipeline welding process. The flaw detection device (10) or ultrasonic weld detection device (29) of the tooling can be equipped with corresponding sensors and data acquisition systems to achieve digital flaw detection.

[0045] Lead Room Flaw Detection Device 10, as the first method of weld inspection, uses X-ray technology to perform internal inspection of the weld. It is paralleled by Ultrasonic Weld Inspection Device 29, providing users with two different inspection options, rather than as a pre- or post-ultrasonic inspection step.

[0046] The operation methods and technical means include: 1. Data collection: Use high-precision sensors to collect signals such as sound waves, electromagnetic waves or rays during the welding process. These signals can reflect the internal structure and potential defects of the welding area.

[0047] 2. Signal processing: Through professional signal processing software, the collected raw data is processed by denoising, amplification and filtering to improve the accuracy and reliability of the data.

[0048] 3. Data analysis: Use machine learning and artificial intelligence algorithms to analyze the processed signals and use pattern recognition technology to compare known defect features to identify defects in the pipeline.

[0049] 4. Big data analysis: Compare the collected data with the large amount of historical data stored in the database, and use big data analysis technology to find out potential defect patterns and regularities.

[0050] 5. Result evaluation: Based on the analysis results, evaluate the welding quality and determine whether repair welding or other repair measures are needed. At the same time, feedback the results to the operator so that appropriate measures can be taken in time.

[0051] 6. Remote monitoring: Through the Internet of Things technology, remote monitoring and control of the flaw detection process can be achieved to ensure welding quality while improving work efficiency.

[0052] 7. Continuous learning: The system's ability to identify and evaluate welding defects will continue to improve over time through continuous learning and optimization.

[0053] Through the above-mentioned technical means, the digital flaw detection operation of this tooling can not only improve the accuracy and efficiency of detection, but also realize real-time monitoring and quality control of the welding process, thereby further improving the overall quality and reliability of marine stainless steel pipeline welding.

[0054] In order to further improve the overall quality and safety of pipelines after welding, a pressure detection device can be added to perform pressure testing on the welded pipeline to ensure that its sealing and pressure bearing capacity meet industry standards. The following are the technical solutions and steps for the pressure detection device: Technical solution: 1. Pressure detection device: Set up a pressure detection device that matches the pipe diameter and material. The device can apply a predetermined pressure to the pipe and can accurately measure the pressure changes in the pipe.

[0055] 2. Interface adapters: Develop a range of interface adapters to ensure that the pressure detection device is compatible with pipes of different diameters and shapes.

[0056] 3. Pressure sensor integration: Integrate a high-precision pressure sensor into the pressure detection device to monitor the pressure in the pipeline in real time.

[0057] 4. Data recording system: Equipped with a data recording system to store data during the pressure test for subsequent analysis and recording.

[0058] 5. Safety valve and pressure relief system: Design safety valve and automatic pressure relief system to prevent the pipeline from being subjected to pressure exceeding its design pressure during testing.

[0059] 6.Automated control system: Develop an automated control system to automatically adjust the pressure and monitor the test process to ensure the accuracy and repeatability of the test.

[0060] Steps: 1. Preparation: Fix the welded pipe after the inspection process including grinding and calibration on the pressure detection device, and ensure the sealed connection between the pipe and the detection device through the interface adapter.

[0061] 2. Set pressure parameters: Set the required pressure test parameters in the automated control system, including maximum pressure value, pressure rise rate and pressure holding time.

[0062] 3. Start the test: Start the pressure detection device and gradually increase the pressure in the pipeline to the set value through the booster pump.

[0063] 4. Real-time monitoring: Use pressure sensors to monitor the pressure in the pipeline in real time to ensure that pressure changes are under the monitoring of the control system.

[0064] 5. Data recording: record the data of the entire pressure test process, including pressure value, time and other relevant parameters.

[0065] 6. Inspection and evaluation: After the pressure holding time is reached, check whether the pipeline has leakage or deformation, and evaluate the pressure bearing performance of the pipeline.

[0066] 7. Pressure relief and analysis: After the test is completed, the pressure in the pipeline is slowly reduced to a safe level through the pressure relief system, and the test data is analyzed to determine whether the pipeline has passed the pressure test.

[0067] 8. Recording of results: Record the test results in quality control documents as part of pipeline quality assurance.

[0068] By adding a pressure detection device, the tooling of the present invention can not only improve the quality control level of the welded pipeline, but also ensure the safety and reliability of the pipeline in practical applications, and meet the engineering requirements under high pressure and complex environments.

[0069] The design concept of this tool is to provide flexibility and selectivity. Lead room flaw detection filming and ultrasonic weld detection are two parallel detection technologies that jointly ensure comprehensive monitoring of welding quality, rather than using one technology as a supplement or replacement for another technology. Although the embodiments of the present invention have been shown and described, it is understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
