Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of welding devices, in particular to a steel pipe welding device for construction. BACKGROUND

[0002] Steel pipes are often used in the process of construction, and according to different use requirements, the steel pipes often need to be welded. In the welding process, not only the positions of the two ends of the welded pipe need to be aligned with each other, but also the center axes of the two pipes to be welded need to be on the same axis, so as to ensure that the pipes are in a stable state during welding. Therefore, when welding, a clamping structure is usually used to clamp and fix the steel pipe, and then a worker manually holds an electric welder to weld the steel pipe.
