Friction Stir Spot-Welding
The motion of the bit eliminates the keyhole as the weld progresses. Higher weld strength and lower corrosion risk when compared to rivets.
Characteristics
Strength, shear resistance, and fatigue resistance at the weld spot are superior to rivets.
Requires no additional materials.
Applications
trains
cars
products for airplanes
