WHERE FSW TECHNOLOGY MAKES A DIFFERENCE
Friction Stir Welding in Defense
FSW technology fortifies defense with durable, resilient and advanced materials.
Unlocking Defense Potential with Advanced FSW Techniques
The defense industry is evolving in an increasingly unstable global context, where nations are accelerating their capabilities while facing constant pressure to reduce costs. Producing more, faster, and more efficiently has become essential, but this race introduces new manufacturing challenges.
In this demanding environment, Friction Stir Welding stands out as a powerful solution. By enabling high-quality, repeatable welds with reduced defects and lower operational costs, FSW supports both performance and efficiency objectives. It allows manufacturers to meet the growing demands of modern defense programs while ensuring reliability, durability and industrial competitiveness.
Defense applications require extreme quality, with strict standards and intensive inspection processes to ensure reliability in critical conditions.
FSW solution: Friction Stir Welding delivers highly consistent and repeatable welds through a solid-state process, eliminating porosity, cracks, and distortion. This results in superior weld integrity that meets the most demanding quality requirements.
Traditional manufacturing processes often involve multiple steps, rework and long validation phases, slowing down production and increasing costs.
FSW solution: Friction Stir Welding simplifies production by consolidating parts into a single structure and reducing post-processing thanks to its high process stability and repeatability.
Conventional welding processes face limitations due to skilled labor shortages and constraints on specialized machinery, reducing flexibility in production.
FSW solution: Friction Stir Welding offers a highly versatile and automated approach, capable of joining a wide range of materials, including complex geometries and dissimilar alloys, with consistent quality.
Exploring FSW Applications in the Defense Sector
In the stringent defense sector, ensuring equipment robustness, adaptability to extreme conditions and longevity, while maintaining operational efficiency, is paramount. Friction Stir Welding steps up to these challenges, offering unparalleled welding solutions tailored to the unique needs and high standards of military applications.
Stiffened panels
They are essential in the construction of armored vehicles and military structures. FSW is widely recognized as the preferred solution for assembling these high-performance defense components.
Tanks
In defense applications, they require maximum strength and perfect sealing. FSW delivers corrosion resistance, simplified designs and consistently flawless welds under pressure.
Cold plates
They play a key role in regulating the temperature of electronic components in defense systems. FSW ensures reliability and long-term performance of these critical thermal management solutions.
Brackets
Brackets used in defense equipment demand extremely high welding quality and consistency. FSW provides a flexible, automated and defect-free solution despite increasing welder shortages.
Battery trays
Defense structures must meet strict requirements in terms of strength, weight, and durability. Combining aluminum extrusions with FSW offers an efficient and highly reliable manufacturing approach.
Ensuring Compliance with ISO 25239 for Critical Applications
Friction Stir Welding (FSW) processes are governed by the ISO 25239 standard, which defines the requirements for welding procedure qualification, operator competency, and quality assurance. Particularly relevant for defense applications, this standard ensures repeatability, traceability, and high weld integrity. By complying with ISO 25239, manufacturers can guarantee that their FSW processes meet stringent quality and reliability expectations required for critical military components.

They Trust Us
“FSW is a complementary technology to the one we used today which was actually brazing and allows us for certain projects, to propose simpler things and faster to implement. The integration of FSW has allowed us to position ourselves on projects on which we were not performing enough. For some customer projects, we are more efficient with FSW. The gains are in waterproofing and lead times compared to brazing. It is your responsiveness and proximity that made the choice”
Robert GLEMOT
CEO of Prolann
“At Calip, we use Friction Stir Welding technology for three main reasons. First, for sealing purposes. Our clients often come to us with sealing challenges for their components and we find that FSW provides the only reliable solution. Second, we value the mechanical strength that FSW offers. As we work with very large profiles that sometimes require reassembly, the mechanical strength of the weld is crucial. The third advantage is repeatability, which ensures consistent quality across multiple welds.”
