| description | The invention discloses a bridge deck unit welding method which comprises the following steps: step 1, processing a U-shaped rib, and mounting the processed U-shaped rib on a bridge deck; 2, shape detection and workpiece welding parameter scanning are carried out on the assembled bridge deck slab; 3, a welding gun is used for conducting backing welding on welding seams on the two sides of the U-shaped rib; fourthly, after backing welding is completed, pressure is applied to the bridge deck slab to conduct reversible deformation operation, and then secondary welding is conducted on a welding seam; and 5, after welding of one side is completed, the steps 3-4 are repeated, and the welding seam capping process of the other side is completed. According to the welding method, intelligent welding of the bridge deck unit is achieved, manual intervention is reduced, the robot with the tracking function is adopted for transverse backing welding, the stability of the U-rib fusion depth is ensured, the U-rib fusion depth |
