when the welding device is used, the first driving oil cylinder 11 pushes the first sliding block 13 to move along the first sliding rail 12 in the axial direction, so that the whole of the rotary assembly 2, the deflection assembly 3, the radial movement assembly 4 and the welding assembly 5 moves back and forth; the power device 23 realizes the meshing rotation with the gear ring 22 through the driving gear 24, and further realizes the integral rotation of the mounting frame 25, the deflection assembly 3, the radial movement assembly 4 and the welding assembly 5; the welding assembly 5 is moved to the place platform 6 of the connecting bar to grasp the connecting bar 7. Then, the connecting ribs 7 are placed between the steel skeletons to be welded through the axial moving assembly 1 and the rotating assembly 2, the integral swing of the radial moving assembly 4 and the welding assembly 5 is realized through the first swing oil cylinder 31 in the deflection assembly 3, the angle adjustment is realized through the second swing oil cylinder 33, the radial moving assembly 4 and the welding assembly 5 are ensured to swing on the tunnel section, and the connecting ribs 7 are moved to the proper positions. Then, the main swing cylinder 51 rotates by a certain angle, so that the connecting rib 7 can enter between the two steel arches 8, and then the main swing cylinder 51 is aligned, and the clamping part assembly 54 moves forward to be tightly attached to the steel arches 8.
Then, the welding head 55 is aligned to the welding position on the side of the connecting rib 7 by the swinging adjustment of the third swinging oil cylinder 531 and the fourth swinging oil cylinder 533 in the mechanical arm assembly 53.
