Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to an automatic welding device for ship piping accessories. Background Art

[0002] In the complex shipbuilding process, the piping system occupies a pivotal position. It is not only the circulation of various liquids and gases inside the ship, but also the key element to ensure the normal operation and safety performance of the ship. The basic construction of this system lies in the precise and stable connection between various pipe fittings. Usually, pipe fittings are produced according to standard lengths, but in the actual installation process, in order to adapt to the complex layout and specific functional requirements inside the ship, the pipe fittings often need to be extended. At this time, welding technology becomes particularly important. In addition, when constructing the piping system, it is inevitable to encounter the turning and branching of the pipeline, which requires a large number of three-way welded pipes, a key component. The three-way welded pipe is the node connecting the three pipelines. The accuracy of its positioning is directly related to the smoothness and stability of the entire piping system. However, in actual operation, how to ensure that the branch pipe and the cross pipe in the three-way welded pipe can be accurately connected has become a technical challenge;

[0003] At present, in order to solve this problem, the method commonly used in the industry is to use two independent fixed structures to position the branch pipe and the cross pipe respectively. Although this method can ensure the welding accuracy to a certain extent, the operation process is relatively cumbersome. It not only requires a lot of manpower and time, but also may cause positioning errors due to human factors, affecting the final welding quality and the overall performance of the pipeline system. For this reason, we propose an automatic welding device for ship piping accessories. Summary of the invention
