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.

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

Our R&D work has delivered a number inventions and developments to industry, including advancing MIG and TIG welding, creating CTOD and methods of understanding of brittle fracture, fatigue design SN curves, linear friction and friction stir welding, local vacuum electron beam welding, and many more. You can find out more on our innovation timeline (see link below) .

As well as our research programmes, we work directly with our Industrial Members through single client projects (SCPs) to provide solutions that directly assist the Member’s business. The work undertaken during SCPs is confidential with the outcomes and associated intellectual property owned exclusively by the client.
