[0025] Specifically, in this embodiment, see Figure 5 , two welding devices need to be used to work together at the same time. First, the two welding devices are placed symmetrically, and the two ends of the steel pipe 51 are placed on the first roller 11 and the second roller 12 of the two welding devices by the pipeline conveyor. The ends of the steel pipe 51 are supported by the first roller 11 and the second roller 12. The driving component 2 is started to drive the two rollers to rotate in the same direction to realize the self-rotation of the steel pipe 51. Before the formal welding, the steel pipe 51 and the flange 52 have been preliminarily connected.

[0026] Take the lap welding of steel pipe 51 and flange 52 as an example, see Figure 6 The first welding gun 37 is used to weld the inner corner of the steel pipe 51 and the flange 52 to form an inner weld 53, and the second welding gun 48 is used to weld the outer corner of the steel pipe 51 and the flange 52 to form an outer weld 54. In this embodiment, the first telescopic arm and the second telescopic arm are electric telescopic rods.

[0027] See also Figure 3 The movable seat 32 slides horizontally forward and backward relative to the equipment body 1, the first slider 34 slides vertically up and down along the movable seat 32, the first slider 34 is rotatably connected to the first telescopic arm, and the end of the first telescopic arm is equipped with a first welding gun 37.

[0029] The equipment design takes into account the welding requirements of steel pipes 51 with different diameters and wall thicknesses. By adjusting the positions of the first welding gun 37 and the second welding gun 48, it can adapt to the welding operations of steel pipes 51 and flanges 52 of different specifications, thereby enhancing the scope of application of the equipment. Through the synchronous welding of two devices with a total of four welding guns, four welds are welded and formed between the two ends of the steel pipe 51 and the inside and outside of the flange 52 in one welding. One or more welding guns can also be freely selected for welding according to welding requirements. After the welding of the steel pipe 51 and the flange 52 is completed, the finished pipe is lifted and transported to the finished material rack by the pipeline longitudinal conveyor and then dropped. The utility model reduces the dependence on manual operation, and the operator does not need to have superb welding technology, which reduces the requirements for the operator's skill level and meets the needs of modern power grid construction for high-quality and high-efficiency welding processes.
