Friction Stir Welding thin section aluminium butt joints

Utilise robotic stationary shoulder FSW to join thin aluminium sections without melting the material.

Use the FSW process to prevent heat distortion, achieving a strong, defect-free joint at thicknesses from 0.3 mm up to 50mm.

A P P R O A C H

Create a reliable, high-strength butt joint in thin-section aluminium, which is prone to warping and defects with traditional welding.

Maintain joint strength and minimise distortion to suit applications with strict weight and durability requirements

OUTCOMES

Consistently strong joints with tensile strength up to 95% of the base material.

Minimal to zero distortion and reduced residual stress, maintaining dimensional accuracy.

High surface quality, reducing the need for additional finishing.
