Choosing the right friction stir welding parameters for aluminum is essential for controlling heat input, material flow, penetration, and weld strength. Among the most important FSW parameters are tool rotation speed, travel speed, and axial force, but the optimal settings vary with aluminum alloy,
FSW has inherent advantages in the lightweighting of rail transit vehicles, particularly in vehicle structures such as body panels, roofs, and floors. It reduces the use of rivets, lowers weight, and enhances structural strength and fatigue performance, meeting the stringent weight and strength requ
In shipbuilding, FSW is used to weld hulls, decks, and cabin bulkheads. This welding method reduces the use of rivets, lowers weight, and enhances structural strength and fatigue performance, improving the sealing and safety of hulls and ensuring the safety performance of ships.
