The shipbuilding industry uses friction stir welding (FSW) to produce aluminum plates from aluminum extrusions, which are widely used in ship superstructures, deckhouses, etc.

A stiffened panel is a critical structural component in shipbuilding, consisting of a skin plate and reinforcing stiffeners welded together. It significantly increases structural strength while reducing weight.

Marine aluminum alloy ribbed plates are a high-performance, high-quality shipbuilding material and are widely used in the shipbuilding industry.
