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
