[0002] In modern industrial production, pipe welding is a very common and important process. Traditional pipe welding methods, such as manual welding, not only require a high level of skill from the welder, but also have low welding efficiency, making it difficult to meet the needs of large-scale production. At the same time, manual welding is easily affected by human factors, resulting in inconsistent welding quality and a high scrap rate. Therefore, it is necessary to use a high-efficiency automated welding device for pipe processing to carry out automatic welding operations.
[0003] However, due to the poor adjustment and positioning capabilities of existing high-efficiency pipe fitting processing automated welding equipment, it is not convenient to position and adjust the pipe fittings according to welding needs during actual use. Usually, it can only clamp and fix the pipe fittings, and it is not convenient to adjust the position of the pipe fittings according to welding needs. The personnel still need to manually adjust and determine the welding position, which is not convenient during placement and positioning, and affects the ease of use. Utility Model Content

The first electric push rod 307 is activated to adjust the length of the first push rod 308, causing it to move the positioning plate 309 and the rubber pad 310. The rubber pad 310 clamps and fixes the pipe fitting in place. Another section of pipe is placed on the first mounting base 306, and the first electric push rod 307 is activated again to clamp the pipe fitting. Then, the drive motor 302 is activated to rotate the adjusting threaded rod 303, causing the positioning sliding screw block 305 to move laterally on the adjusting threaded rod 303, moving the first mounting base 306 and thus moving the pipe fitting to the position of the other section. The movement position of the pipe fitting is detected by the infrared laser displacement sensor 12, which uses Keyence technology.

As needed, the second electric push rod 7 is activated to adjust the length of the second push rod 8, which pushes the laser welding gun 9 to move and perform welding operations on the longitudinal position of the pipe. The laser welding gun 9 uses the EN-FCX1500 welding head model.
