The limiting bolt 4 passes through the inside of the limiting slider 3, and the limiting slider 3 is threadedly connected to the limiting bolt 4. By setting a rotatable first limiting plate 6, the first limiting plate 6 can be adjusted to a designated position, and the first limiting plate 9 is movably connected to the first limiting plate 6. The two limiting plates 9 work together to fix the two steel pipes to be welded at a specific angle, so as to facilitate welding the two steel pipes at a certain angle, making the welding of steel pipes simple and convenient and improving the welding efficiency of steel pipes; the fixed bracket 7 is fixedly installed above the first limiting plate 6. The fixed bracket 7 has a first adjusting threaded rod 8 installed inside the threaded part of the first adjusting threaded rod 8. The first adjusting threaded rod 8 is installed below the limiting pressure plate 11. The limiting pressure plate 11 has a first connecting bearing 12 installed inside the limiting pressure plate 11. The first adjusting threaded rod 8 is installed on both sides of the first adjusting threaded rod 8. The lower surface of the limiting pressure plate 11 has a limiting pressure groove 13.

[0021] Working principle: When using this steel pipe auxiliary welding mechanism, firstly rotate the first limiting plate 6 to adjust the included angle between the first limiting plate 6 and the second limiting plate 9 to the specified angle. Then, tighten the limiting bolt 4 on the limiting slider 3 so that the limiting bolt 4 abuts against the bottom of the limiting groove 2, thereby fixing the adjusted first limiting plate 6. Next, place the steel pipe to be welded in the limiting support groove 5 inside the first limiting plate 6. Then, rotate the first adjusting threaded rod 8 in cooperation with the limiting auxiliary rod 10 to push the limiting pressure plate 11 downward, which cooperates with the limiting pressure groove 13 to fix the adjusted steel pipe to be welded.
