This production line is the specialized production line for high efficiency large mass production bridge U rib, there is base plate alignment assembly positioner, U rib port keyhole precise positioning device, movable U rib assembly machine, swing type anti-distortion assembly positioner, five head double wire U rib gantry welding machine, U rib unit mechanical rolling&straightening machine.

1).Base plate alignment assembly positioner, U rib port keyhole precise positioning device, movable U rib assembly machine, swing type anti-distortion assembly positioner, five head double wire U rib gantry welding machine, U rib unit mechanical rolling&straightening machine realize automation of U rib assembly, welding and straightening process. U rib through U rib installing machine auto-spot welding and install on single plate, U rib process hull auto-welding multi-longitudinal, after positive and negative bias hull welding then can complete the whole welding work, use U rib unit straightening machine to straighten U rib. Greatly improve production efficiency and reduce labor intensity.

2). Assembly line is equipped with two sets of U rib assembly machine, four U rib mounting areas.

3). Welding line is equipped with 8 sets of swing type anti-distortion jig and welding fixture, four 5 heads U rib double wire gas shielded welding machine.

4). Gas shielded welder current and voltage centralized control, each welder has trimming function.

5). CO2 gas concentration supply and unified management.

6). When welding adopt automatic tracking, has the function of multi-welding torch striking and quenching of arc at the same time.

7). In order to protect workers' health there is welding smoke dust remover to centralized dedust multi-head torch.

8). After welding board unit is mechanical straightened, greatly reduce flame baking.
