International Symposium on Friction Stir Welding

14th International Symposium on Friction Stir Welding

TWI, Cambridge, UK on 19 - 21 May 2026

We will be holding the 14th International Symposium of Friction Stir Welding from 19-21 May, 2026, at TWI Cambridge.

Friction stir welding (FSW) was invented at TWI in 1991 and continues to grow as a mature process for joining aluminium and many other engineering alloys.

The cost benefits of the FSW process have provided economic advantage to numerous organisations around the world, and 14ISFSW will provide an unrivalled opportunity to meet leading authorities on FSW including researchers, practitioners, customers and suppliers.

About the Symposium

The 2026 Symposium has particular significance as it will be held at TWI, where FSW was invented in 1991. In the years since, we have made major advancements in the technology, and continue to lead developments in FSW today.

The International Symposium will be the largest friction stir welding event in 2026, with more than 80 papers planned to be presented in oral sessions and poster presentations.
Topics covered in the symposium will include: 

• New developments in processes and control
• Improved tool technology
• High-temperature materials
• Additive techniques
• Fundamentals and modelling
• Metallurgical characteristics
• Mechanical properties
• Dissimilar materials joining
• Industrial applications
• Friction stir spot welding

Please note that a call for abstracts will be made in August 2025, but in the meantime please mark your diaries for what promises to be another unmissable event.
