About TWI

Providing solutions and adding value

TWI is one of the world’s foremost independent research and technology organisations, with expertise in materials joining and engineering processes as applied in industry. TWI specialises in innovation, knowledge transfer and in solving problems across all aspects of manufacturing, fabrication and whole-life integrity management.

Established in Cambridge, UK in 1946, the organisation has gained a first-class reputation for service through its teams of respected consultants, scientists, engineers and support staff. Now, approaching 1000 employees, it works with over 1800 Industrial Member companies in 70 countries.

TWI currently operates from 54,000 square metres (581,000 square feet) of manufacturing, testing and training space; five UK and 13 overseas facilities serve both its Industrial Membership and its training and examination needs. A successful international Training and Examinations programme sees 25,000 students trained each year in welding and inspection technologies.

In 2015, TWI opened three new laboratories at its Cambridge headquarters, including state-of-the art facilities for the National Structural Integrity Research Centre, a dedicated postgraduate centre for industry-led engineering research.

Alongside is its management of an Innovation Centre hub where a growing number of Innovation Centres are positioned to share research and technology capabilities, undertake joint research programmes and develop the next generation of technologies and engineers in the selected research disciplines.

TWI also houses a professional institution, The Welding Institute, with a separate membership of 6000 individuals.
