Ultra wide aluminum friction stir welding plate with ribs are aluminum alloy plates manufactured using FSW (Friction Stir Welding) technology, which usually include rib structures. The maximum width of extra wide FSW ribbed aluminum plates can reach 6000mm and the maximum length can reach 15m. The thickness range is wide, ranging from 3mm to 8mm. The maximum rib height can reach 150mm‌.

The ultra wide aluminum friction stir welding plate with ribs has the following characteristics:

- High strength and light weight: Due to the use of aluminum alloy materials, especially high-strength aluminum alloys such as 5083, these aluminum alloy plates achieve weight reduction while ensuring sufficient strength, which is particularly important for ship design.

- Good welding quality: FSW is a solid-state connection process that does not produce defects such as pores and cracks that are common in fusion welding, thereby ensuring the quality of the joint.

- Low deformation and high precision: Compared with traditional welding methods, FSW produces lower heat input, so the deformation after welding is smaller, which helps to maintain the accuracy and flatness of the plate size.

- Excellent corrosion resistance: Aluminum alloys have good corrosion resistance, especially in marine environments, which makes ribbed aluminum plates very suitable for shipbuilding.

In the shipbuilding industry, this type of ultra wide aluminum friction stir welding plates can be applied to the following key parts:

- Hull structure: including the inner and outer plates of the hull and the deck, especially for those parts that need to withstand greater pressure or stress.

- Superstructure: such as the cab, living cabin and other parts, because they have high requirements for weight reduction, and also need to have sufficient rigidity and stability.

- Internal partitions and supporting structures: In order to optimize the spatial layout and improve the stability of the overall structure, plates with ribs are often used as partitions or supports.

- Special use areas: such as cold storage rooms, cargo holds and other places that require special environmental control, because these places may require better sealing and thermal insulation.

The ultra wide aluminum friction stir welding plate with ribs can not only improve the overall performance of the ship, but also reduce maintenance costs, and help achieve more efficient production and assembly processes. With the development of technology, the application scope of friction stir welding is constantly expanding and has become an indispensable part of modern shipbuilding.
