[0002] Large-diameter pressure pipes are often used to increase throughput, and welding multiple large-diameter pressure pipes together is a critical step in pipeline networks. Existing welding devices typically only weld two pipes together, leaving welds fragile and prone to breakage when rotated.
[0003] For example, the Chinese patent publication number "CN221603607U" discloses a "pipe welding device", which includes a fixing frame and an equipment base. A welding frame is provided on the top of the equipment base, and a welding element is provided on the top of the inner wall of the welding frame. Two sets of slide grooves are opened on the top of the equipment base, and a guide rod and a bidirectional screw rod are respectively provided inside the slide grooves. This application arranges corresponding pipe clamping and fixing mechanisms on both sides of the welding structure. The pipe clamping and fixing mechanisms can be moved and adjusted according to the length of the pipe, so as to fix the pipe mouth and pipe body of the pipe to be welded.
[0004] However, the rotating wheel of the above-mentioned device drives the pipeline to rotate under the drive of motor three, so that the welding element completes the welding of the pipe mouth around the circle. However, at this time, the two pipelines are only partially welded together and have not been completely welded together. The weld is still relatively fragile. If the two pipelines are rotated at this time to achieve the welding of the pipe mouth around the circle, it may cause the newly welded part to break, posing a safety hazard. Summary of the Invention
