[0002] Seamless steel pipe is a steel pipe without welds on the surface. It is made by perforating a whole round steel. In many engineering applications, multiple sections of seamless steel pipes need to be connected to form the required length. The seamless steel pipe welding support device is a special equipment used to fix and support the steel pipe during the welding process. Its purpose is to ensure the quality and accuracy of the welded joint.

[0003] When using the current seamless steel pipe welding support device, workers often find that: currently, most of the support frames are used to support and limit the two sections of steel pipes so that their interface ends are butted together to prevent movement. Then the workers use a welding gun to weld them. Since the seamless steel pipe needs to be welded along the outer diameter for a circle, the connection at the bottom is blocked by the steel pipe, which makes it inconvenient for the workers to weld, resulting in reduced welding accuracy.
