AEE’s friction stir welding (FSW) technology is widely used in aerospace component manufacturing, especially for rocket fuel tank production. It enables high-strength, low-defect welds for lightweight structures, helping meet strict aerospace requirements for safety, reliability, and performance.

Main Applications

01 Rocket Tanks (Core Application)

Applicable to rocket fuel tanks and liquid hydrogen storage tanks, FSW enables high-quality welding of AA2219 aluminium alloy and critical cylindrical tank seams. The joints offer strong leak resistance, reliable cryogenic performance, and long-term service durability.

02 Fuselage & Structural Panels

Provide durable, lightweight, high-precision welds for aluminium and aluminium-alloy components used in aircraft and spacecraft.

03 Reinforcement Plates & Lightweight Frames

Enable efficient assembly, ensure excellent component durability, and provide structural support for rockets and spacecraft.

Advantages

High-Strength Welds

Creates strong, low-defect joints for critical components such as rocket tanks.

Lightweight Design

Balances strength and weight reduction to improve launch-vehicle payload efficiency.

Precision & Low Distortion

Provides repeatable, low-heat welding with minimal distortion and less post-processing.

Flexible Joining Solutions

Adaptable to advanced rocket tanks and aerospace structures in different materials and sizes.
