[0002] During the construction of water conservancy and hydropower projects, pipes are connected by welding. Initially, manual welding was used, which was inefficient and the weld quality was greatly affected by the experience of the construction workers, resulting in inconsistent weld quality. Later, welding equipment was developed to replace manual welding, improving both efficiency and the stability of weld quality.

[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN222243225U discloses a water conservancy pipeline welding device, which can synchronously drive two water conservancy pipelines on the left and right sides to move inwards, so as to achieve a tight connection at the joint of the two water conservancy pipelines. It is more convenient and faster than manual subsequent adjustment. However, it uses a positioning plate to clamp and fix the pipeline, which is not convenient to rotate the pipeline and makes it difficult to achieve circumferential welding on the outside of the pipeline.

[0004] Therefore, it is necessary to design an automatic welding device for water conservancy and hydropower engineering pipelines that can achieve a tight connection at the joint of two water conservancy pipelines, while facilitating the rotation of the pipelines to realize external circumferential welding and improve welding efficiency, in order to solve the current technical problems.

[0012] The lifting plate has an opening that cooperates with the welding mechanism.

[0013] The welding mechanism has a welder, and a Z-axis driving component is provided on one side of the welder to drive it to move along the Z-axis direction.

Specifically, the outer side of the friction rollers 81 is fitted with anti-slip sleeves to increase the friction between the friction rollers 81 and the outside of the pipes 9.

Specifically, both the Z-axis drive component 62 and the X-axis drive component 63 are linear modules.
