[0002] With the rapid development of modern architecture and industry, steel pipe rods are widely used in various scenarios as important structural support components. Most of the steel pipe rods are made of a single steel plate. After forming a cylinder, a gap will remain on the surface of the steel pipe, which needs to be welded. During the joint welding of the steel pipe rod, it is usually necessary to limit it to avoid deformation and expansion of the steel pipe rod due to tension during the joint welding. For this reason, a joint support seat is usually used to position and support the joint of the steel pipe rod.

[0003] During the process of welding steel pipe joints, the existing steel pipe rods are usually simply placed on the support seat and clamped and loaded by the support seat.

The support seat cannot adapt to the clamping and loading according to the changes in the diameter size. The multi-tube joint operation capability is not good enough, and the versatility and flexibility are insufficient.
