FSW APPLICATION
Stiffened Panels Welded by FSW
Enhanced technical characteristics of aluminium stiffened panels through Friction Stir Welding.
Why Choose Friction Stir Welding for Your Stiffened Panels Assembly?
Aluminium stiffened panels comprising a “skin” sheet and stiffeners, are widely utilized in industries like aeronautics, automotive, railways, naval and bridge construction. Formerly assembled primarily through riveting or MIG welding, these panels are increasingly being joined using FSW welding due to its superior technical benefits in the assembled components.
No Risk of Leak
Ranging from vacuum to any liquid, as FSW is a solid-state welding process, thus eliminating porosity.
Wider Panels
With FSW, aluminium profiles, which must be less than 400 mm wide, can be butt welded to overcome this limitation.
High Mechanical Resistance
FSW results in 2 times higher mechanical resistance compared to MIG or TIG. This results in a weight reduction of 10%.
Cost Divided by 10
Compared to MIG or laser welding, FSW offers a more economical solution (no gas, no wire, few electrical energy).

Battery Trays: A Key Application for Stiffened Panels in EVs
Why Friction Stir Welding for Battery Trays?
Battery trays in electric vehicles (EVs) demand robust and lightweight designs to ensure safety, efficiency and performance. Friction Stir Welding offers unique advantages for assembling stiffened panels in battery trays. It ensures zero leakage, providing airtight and watertight seals critical for protecting battery modules. The technology also delivers a high strength-to-weight ratio, reducing overall vehicle weight while maintaining structural integrity. Additionally, FSW enhances thermal conductivity, optimizing battery performance and extending its lifespan.
Proven Results in EV Manufacturing
FSW’s precision and repeatability have been successfully applied in creating battery trays for leading EV manufacturers, showcasing:

Aluminium Stiffened Panels: Key Concerns for Critical Sectors
In the realm of advanced manufacturing, the emergence of Friction Stir Welding as a reliable technique has transformed how industries approach assembly and design. FSW-welded stiffened panels stand out, not just for their robustness but also for their adaptability and efficiency in construction. These panels are renowned for their mechanical stability, lightweight attributes and resistance to environmental challenges, qualities that are sought after in high-demand sectors. Industries ranging from automotive to aerospace, from shipbuilding to railway, have witnessed the transformative benefits of these welded panels
Stiffened panels play a pivotal role in various sectors where high mechanical resistance is imperative:
They Trust Us
“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.”
Gabriel Venet
Doctor of mechanical engineering
“FSW technology has the possibility that, when you weld, you don’t degrade the material as other process or other joining technologies. The main advantage that we see at Stirweld is the intercompability and the flexibility that the head provides us compared with a dedicated machine.”
