[0002] "Welding" in the field of industrial production and metal processing usually refers to welding, which is a technology that permanently connects two or more metal parts together by applying heat, pressure and forming a common or filler material (weld) between molecular layers to form a joint.

[0003] The existing small-aperture positioning ring welding device drives the clamping plate to approach the pipe that needs to be ring-welded through the driving module, fixes the outer sides of the two pipes that need to be ring-welded, positions and fixes the pipes, and then extends the welding device into the pipes to perform ring welding on the joints between the pipes. However, in actual use, due to the relatively simple positioning structure and positioning direction of the pipes, it is only necessary to position the pipes, and it is difficult to ensure that the end faces of the two pipes are in close contact, so that the joint between the two pipes cannot be in close contact during welding, resulting in poor welding effect and affecting the quality of the ring welding.
