Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding devices, in particular to a pipeline welding device used for water and electricity installation. Background Art

[0002] At present, there are more and more pipeline construction projects for transporting various gases and liquids. The technical safety requirements for pipelines during construction are relatively high, especially when the pipelines are welded together, the allowable deviation accuracy is high. When the pipelines are butt-jointed, the size of the butt joints, the roundness of the pipe ends, the straightening of the pipelines, and the leveling of the misaligned ends all need to be corrected.

[0003] Pipeline docking and correction are relatively difficult. Therefore, in actual construction, constructors sometimes force the pipelines to be assembled and aligned, such as using heavy objects to knock on the pipe mouth to achieve correction. This will cause quality problems in the pipeline welding parts, affect the construction progress, waste manpower and material resources, and even cause safety hazards and economic losses to the commissioned pipelines.

[0004] Furthermore, the design and functionality of pipe welding equipment for hydro installations may vary depending on the specific application and requirements. Utility Model Content
