Navel Aluminum Profile Sheet

With the rapid development of the shipping industry, ship design and manufacturing follow the concept of lightweight structure. More and more naval aluminum alloy structures are widely used in superstructures of speedboats, cruise ships, hovercraft and large ships。

Generally, the plate thickness of aluminum alloy structure is relatively thin, and the ribs on the plate are arranged densely. If the structure with conventional incision form is used, the welding workload is too large, and the post-welding yield strength of aluminum alloy will be reduced.

Therefore, in order to improve construction efficiency, reduce welding workload and the adverse effects of welding on structural performance, a large number of aluminium profile sheets,that is, ribbed plates are used in aluminum alloy hull structures, and beams, ribs, and longitudinal girders are directly installed on the integral ribbed plate profiles, and connected to the integral ribbed plate frame through connectors and brackets.

The suspension structure has obvious construction advantages compared with the conventional longitudinal frame structure. It can improve construction efficiency and control welding deformation during the construction of the ship.

In order to reduce welding deformation and improve construction efficiency, the suspended structure should be used as much as possible in the plane structure. In the usual hull suspension structure, the connection structure is generally welded between the outer plate and the beam.

In the specific design, according to the stress form of different parts, there are connectors set every other or every two longitudinal bones, and connectors are set only on the end face. In order to reduce the weight of the hull, improve the construction efficiency, and control the welding deformation during the construction of the hovercraft, most of the internal structures of large hovercraft adopt the hanging structure of the integral wall plate.

Function of ribbed sheet

1. The aluminum profile sheet can enhance the strength and rigidity of products without increasing the wall thickness of products, so as to save material consumption, reduce weight and reduce costs.

2. It can overcome the distortion of products caused by uneven stress due to differences in wall thickness.

As an emerging welding process, friction stir welding has been rapidly and widely recognized and applied in the industrial field due to its stable and excellent joint performance and automated welding characteristics.

Haomei Alumium has a batch production line for friction stir welding wide stiffened aluminum plates. The longest product is 28m long and 5.8m wide, and the product qualification rate can reach 100%.
