Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe processing, in particular to a steel pipe segmented synchronous welding device. Background Art

[0002] Segmented back welding refers to a welding process in which the weld joint is divided into several sections and welded in sections when the weld is long. The welding direction of each section is opposite to the growth direction of the entire weld. When welding steel pipes in sections, since the steel pipes are long and the welding gun cannot cover the entire length of the steel pipe, the steel pipe needs to be moved to move the welding position to the welding gun. However, the steel pipe itself has a length, and the setting of a pushing device makes the overall length of the equipment too long, occupying a large plant space, which is not suitable for the operation of small-scale plants.
