Triton Tooling

Friction Stir Welding

Friction Stir Welding (FSW) was invented in 1991 by Wayne Thomas at TWI. The process operates below the melting point of the workpieces which leads to very high strength and minimal distortion.

The process is used in many sectors including: aerospace, railway rolling stock, automotive and ship building.
It is increasingly being adopted by electric car manufacturers for the production of battery trays.

Benefits of the process include greater weld strength, little or no post-weld repair, no welding fumes or gases, minimal workpiece distortion, little to no porosity, no filler metals required, improved corrosion resistance, no solidification cracking and lower cost in production applications.

We work closely with a variety of clients in the Friction Stir Welding industry, including TWI Ltd, to provide bespoke FSW tooling to worldwide customers.

Our customer base includes clients from industry leaders as well as universities and research companies.

We were also one of the original members of the Eurostir project.

Triton Tooling was a consortium member of the Mobi-Weld project
