The second metal tube 16 is inserted into the fixed sleeve 21 on the other side of the workbench and fixed by the locking bolt 22. Then, under the intervention of the operator, the bearing seat 19 is pushed, so that the adjacent ends of the first metal tube 15 and the second metal tube 16 are in contact with each other. Then, the first driving motor 5 of the first driving mechanism drives the first lead screw 4, so that the first moving block 7 moves up and down along the first lead screw 4, thereby adjusting the position of the support frame 8. A second driving mechanism is provided inside the support frame 8. The second driving motor 10 of the second driving mechanism drives the second lead screw 9, so that the second moving block 12 moves left and right along the second lead screw 9, thereby adjusting the positions of the welding machine 13 and the welding torch 14, so that the welding torch 14 is aligned with the position where the first metal tube 15 and the second metal tube 16 are in contact, realizing precise welding. When a solder joint is formed at the position where the first metal tube 15 and the second metal tube 16 are in contact, the control panel 28 is used to control the reduction motor 18 to drive the three-jaw chuck 17 to rotate slowly. Since the bearing seat is rotationally connected to the rotating rod 20, and one end of the rotating rod is fixedly connected to the fixed sleeve 21, the first metal tube 15 and the second metal tube 16 can be driven to rotate simultaneously, so that the welding torch 14 is aligned with the outer peripheral side where the first metal tube 15 and the second metal tube 16 are in contact for all-round welding, thereby forming the required metal railing.
