1.Joint board station
Match with a set of steel joint board device(including thickness difference adjusting device and steel plate surface alignment processing facilities) and steel plate transmission positioning adjusting device. On the steel platform, after positioning adjusted the steel plate through manually align and press the surface, and then spot weld and montage. If two plate of different thickness need to be spot welding, the plate thickness difference adjusting device can adjust height to ensure the upper surface of the plate is flat when spot welding, then process manual spot welding.

2. Single face welding position
Match with 2 sets of movable FCB devices, simultaneously double-face forming welding two welding seam, until complete welding all welding seam.
Chain type transmission conveyor system transmit the welded steel to the mark, check, repair and cutting station.

3. Mark, check, repair, cutting station
Steel plate should process necessary examination and repair when inspecting pit, cut off arcing plate and arc plate.

4. Longitudinal vertical transfer station
Adopt roller transmission method, the tray rack filled with longitudinal is transported from workshop C area to B area, empty tray rack can be transported via the above-mentioned path back to the longitudinal conveyor belt of workshop C area.

5. Longitudinal assembly tack welding station
At the front of longitudinal installing station, after steel is in the place, the tray rack loaded with longitudinal is shipped to this station. Trolley take out longitudinal from the tray rack and transmit the longitudinal to the needed assembly position, then assembly gantry press the longitudinal on steel plate (if necessary, use the pulling up device on the steel plate to pull up steel plate, make it better fit with longitudinal), the spot welding system on gantry process spot welding. After spot welding, the door frame begin to assemble the next longitudinal.
Chain conveyor system will transport the segmentation loaded with longitudinal segmentation to the longitudinal angle welding station.

6. Longitudinal angle welding station
Equipped with a longitudinal angle welder with 24 electrodes (welding head), it can simultaneously weld six longitudinal. Complete longitudinal angle weld segmented by the segmentation carrier truck transport to the rib plate girder mounted station, or transport to traverse moving station then transport out to the other line.

7. Rib, girder assembly station
Each line is equipped with two rib girder spot welding gantry. After segment is in place, the rib and girder which need to be installed is transmitted into the mounting spot welding position, each door frame is equipped with six sets CO2 welding device to weld rib and longitudinal steel together, complete basic installation spot welding work. Complete rib and girder spot welding segmented, use the segmentation carrier truck transport to the next rib, girder welding station.

8. Rib, girder welding station
Each line is equipped with three rib girder welding door frame, mainly weld rib and girder. Each door frame is equipped with 12 sets of CO2 welders. The wire feeder and torch of all 12 sets of welders are hanging under the electric chain hoist hanger of main beam.
After welding is completed, sub-carrier truck will transport the segmentation to the next station.

9. Segmentation move out station
After complete above work, segmented is transported by the segmentation transport carrier to move out station. At move out station segmentation use segmentation jacking device to jack to 2.5 from ground. Then use hydraulic flat trolley to transport into bottom of segment. Jacking device put segment onto flat trolley. Segmentation is transmitted out segmentation production workshop by hydraulic flat truck.

10. Segmentation transmission trolley
After longitudinal welding station is completed, through segment trolley complete transport the following all station segment.

He assembly and welding production line is used for assembly and welding parts of hull, production line set distribution station, one tack welding station and four angle welding station. Station consists of working platform, conveyor lifting device and transmission conveyor. The workpiece transmission between working stations use roller transmission system, welding method adopts semi-automatic CO2 gas shielded welding, welding device is mounted on the movable half gantry, welding gantry mainly used for complete the welding work of parts on the platform.

The pipeline is a highly efficient mass production specialized for marine T-bar, there is panel positioning device, web positioning device, T-bar assembly, tack welding device, T-bar shunt device, panel four corners chamfering device, T-bar sidesway discharging device, T-bar gantry type welding machine, T-bar straightening machine, transmission conveyor and other auxiliary equipment, achieve automation of T-bar assembly process. The whole process is automatic controlled by PLC, every process has a security alarm and interlock to ensure that every aspect of safety, order production.
