Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline welding, and in particular relates to a pipeline welding mechanism. Background Art

[0002] When two pipes are butt-jointed, they need to be fully welded to ensure the stability of the two pipes after butt-jointing. When butt-jointing, a pipe welding mechanism is needed, such as the existing patent with the publication number "CN114043114B" which discloses "a pipe automatic butt-jointing full welding device; comprising a frame, a pipe feeding track, an automatic butt-jointing mechanism and a rotary welding device, the pipe feeding track is arranged at the lower end of the frame, and the automatic butt-jointing mechanism is arranged directly above the pipe feeding track; the automatic butt-jointing mechanism comprises a first connecting column, a cross arm and a second connecting column connected in sequence, and the end of the first connecting column is connected to the hydraulic device through a slider..."
