The horizontal height adjustment of the welding steel pipe 9 can be controlled by coordinating the telescopic lengths of the two first telescopic rods 6 to ensure that the welding steel pipe 9 is horizontally sleeved on the docking auxiliary block 21 on one side of the two grinding discs 17. When the welding steel pipe 9 is sleeved on the docking auxiliary block 21, the welding steel pipe 9 will tilt under the guidance of the guiding conical surface 22.

[0024] A welding method using a welding adjustment device comprises the following steps: Step 1: Pass the two welded steel pipes 9 horizontally through the fixing slots of the two fixing frames 5, and then the two first telescopic rods 6 of the fixing frames 5 respectively control the two movable wheel plates 7 to move toward the welded steel pipes 9. At this time, the eight clamping and fixing wheels 8 clamp and fix the welded steel pipes 9 horizontally; Step 2: The moving screw rod 3 controls the two moving seats 4 to move relative to each other. At this time, the end of the welding steel pipe 9 contacts the guiding conical surface 22 of the docking auxiliary block 21. Under the conical guiding action of the guiding conical surface 22, the welding steel pipe 9 is sleeved with the docking auxiliary block 21 and contacts the grinding surface of the grinding disc 17. During this period, as the welding steel pipe 9 approaches the grinding disc 17, if the welding steel pipe 9 tilts up and down, the extension length of the two first telescopic rods 6 can be adjusted to keep the welding steel pipe 9 and the docking auxiliary block 21 in a horizontal posture; Step three: The movable driving seat 14 drives the two mounting turntables 16 and the grinding disc 17 to rotate at high speed.
