The Welding Institute or TWI is a research and technology organisation, with a specialty in welding. With headquarters six miles south of Cambridge, Cambridgeshire, England, since 1946, and with facilities across the UK and around the world. TWI works across all industry sectors and in all aspects of manufacturing, fabrication and whole-life integrity management technologies.
TWI services include consultancy, technical advice, research and investigation for industrial member companies and public funding bodies. It also offers training and examination services in NDT, welding and inspection across the globe.
Employing over 800 staff, TWI serves 700 Industrial Member companies across 4500 sites in 80 countries. The formation in 1922 of its professional institution, The Welding Institute, and the later establishment of the British Welding Research Association (BWRA) in 1946 provided the basis of the company group as it is today. The Welding Institute currently has a separate membership of over 6000 individuals.
Friction stir welding was invented by TWI in 1991.
The Professional Division of TWI is a Licensed Member of the Engineering Council. It is situated at Granta Park, at the junction of the A11 and the terminus of the A505, three miles east of Duxford Museum.
Both industrial and professional members are represented on the Council that oversees TWI’s business and the operational activities of its Directors.
The organisation has international branches in Australia, Bahrain, Canada, China, India, Indonesia, Malaysia, Pakistan, Thailand, Turkey, United Arab Emirates and North America.
The Welding Institute (TWI Professional Group) is a direct descendant of the Institution of Welding Engineers Limited, which began when 20 men gathered on 26 January 1922 in the Holborn Restaurant in London and resolved to establish an association to bring together acetylene welders and those interested in electric arc welding. The date of registration under the Companies Act was 15 February 1923. Slow growth over the next ten years saw Membership grow to 600 with an income of £800 per annum.
In April 1934, the Institution merged with the British Advisory Welding Council to form a new organisation – the Institute of Welding. A symposium that same year, Welding of Iron and Steel, held in conjunction with the Iron and Steel Institute, showed the need for a research programme. It took the threat of war, the Welding Research Council and modest funding from the Department of Scientific and Industrial Research (DSIR), to generate the will and ability to commence such a programme in 1937. The Institute had no laboratories of its own and supported work, mainly in UK universities.
