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

Friction stir welding (FSW), as a solid phase welding technology, is widely used in the manufacture of large-size aluminum alloy panels for use in marine and offshore applications.

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.
