Who We Are

Our purpose is to help people and organisations maximise the performance of welding, joining and allied processes; and the resulting products and assets they create.

We are a membership-based organisation, supporting both individuals and companies alike. We exist to provide authoritative and impartial expert advice, knowhow and safety assurance through engineering, materials and joining technologies – helping you design, create and operate the best products possible.

Descended from the British Welding Research Association (BWRA), we have grown into one of the foremost independent research and technology organisations. We span innovation, knowledge transfer and problem resolution across all aspects of welding, joining, surface engineering, inspection and whole-life integrity management.

TWI’s single client projects bring together experts from TWI and the Member to provide solutions directly focused on assisting the Member’s business. The work undertaken is confidential with the outcomes and associated intellectual property owned exclusively by the client.
