Friction stir welding (FSW) is an innovative solid-state joining process, performed without melting or filler material. Ideal for aluminium alloys, it ensures perfect sealing, excellent mechanical strength and preserves the metallurgical properties of the materials. The process guarantees consistently high weld quality, without porosity or thermal distortion.
Calip Group masters FSW for the assembly of complex aluminium parts, offering a reliable alternative to conventional welding techniques. This solution combines industrial performance, sustainability and environmental responsibility, using a clean, fume-free and gas-free process that is perfectly suited to the requirements of advanced industries.
FSW is based on a mechanical mixing process through friction, which joins materials in a plastic state. It generates very little heat, avoids deformation and eliminates common welding defects such as porosity, cracks or inclusions. The process offers:
With a machine fleet dedicated to FSW, we apply this technology to large or technically demanding parts : long aluminium profiles, cold plates, enclosures, mechanical components... Welding is carried out with micrometric precision under fully controlled conditions.
Our clients benefit from custom-made solutions, developed with speed, precision and full traceability.
As part of a continuous improvement approach, Calip Group collaborates with specialised institutes such as Institut de Soudure and CETIM, and is a member of Printing in Bourges.
These partnerships strengthen our technological monitoring, certification levels and ability to offer ever more advanced solutions. Our FSW expertise is part of a long-term industrial quality and innovation strategy.
Solid-state process
A weld performed without filler metal or material fusion, reducing the risk of deformation, cracking or porosity. Ideal for high-value aluminium alloys.
Excellent mechanical strength
FSW joints offer high mechanical resistance and long-term reliability, even under significant structural stress.
Environmentally responsible
A clean, energy-efficient process with no gas emissions or polluting consumables. FSW supports sustainable industry and low-carbon manufacturing.
Industrial applications
FSW is ideal for joining complex aluminium components in aerospace, defense, mobility and embedded electronics sectors.
