The welding body 14 is driven to move forward. After the welding body 14 moves to the turntable 3, the rotation of the rotating roller 13 is stopped, and the welding work can be carried out. The component 21 to be welded is inserted between the semicircular ring 17 and the arc plate 18. The motor 23 drives the end of the clamping plate 24 to rotate to the outside of the end of the component 21 to be welded. The driving end of the oil cylinder 22 extends out to push the clamping plate 24 to move. The clamping plate 24 contacts the component 21 to be welded, and the component 21 to be welded is pushed to move so that it contacts and presses against the welding body 14. The mechanical arm and the laser welding gun are started, and the welding work at the connection between the welding body 14 and the component 21 to be welded is completed by the high-energy laser beam emitted by the laser welding gun;

[0028] Furthermore, to ensure that the welding body 14 can be placed in alignment with the turntable 3, a rotatable or movable baffle can be set on the surface of the workbench 1 to prevent the welding body 14 from moving forward so that the welding body 14 falls on the turntable 3. When subsequent welding is completed, the baffle can be rotated down or retracted.
