Earlier institution

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.

Formation

TWI Technology Centre at Catcliffe

In April 1934, the Institution merged with the British Advisory Welding Council to form a new organisation – the Institute of Welding.

This was important to the later creation of TWI Ltd as it took the scope of the Institute beyond personal professional membership to also include industrial member companies in order to further support research activities.

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.^[[2]] The Institute had no laboratories of its own and supported work, mainly in UK universities.

Research association

In the late 1940s, a move was made to transform the Welding Research Council to the recently established status of Research Association, thereby giving it access to DSIR funding in proportion to that raised from industry. At the time, professional institutions were debarred from acting as Research Associations^[[3]] The debarring of professional institutions from acting as research associations forced the two arms of the Institute to split in 1946, leading to the creation of the British Welding Research Association (BWRA) as a separate entity to The Institute of Welding.

Cambridgeshire

In 1946 the BWRA bought Abington Hall, near Cambridge, UK, a country house and grounds in poor repair, for £3850 and commenced business under Allan Ramsay Moon as its director of research. The first welding shop was established in stables adjoining the house, and fatigue research commenced under Dr. Richard Weck.

BWRA also occupied a house in London, 29 Park Crescent, which it converted into a metallurgical laboratory, with the butler's pantry becoming the polishing room and the coachman's quarters, the machine shop.

Ramsay Moon left after one year, disillusioned at the grant of only £30,000 from DSIR, and it fell to Dr. Harry Taylor to grow the organisation into a viable business.^[[4]]

In 1948, The Welding Institute celebrated its silver jubilee with the award of a Grant of Arms by the College of Arms. The coat of arms depicts a joint being made through the application of heat with a Latin motto that translates as ‘out of two, one.’

Academic programmes

Meanwhile, The Institute of Welding had bought property in London very close to the Imperial College of Science and Technology. It ran an expanding training programme through its School of Welding Technology and later the School of Non-Destructive Testing in what is a clear forerunner to today's TWI Training.

The first course, on the welding of pressure vessels, saw nearly 100 applicants for the 40 places, demonstrating a need for such courses.

Merger

In 1957, Richard Weck, became Director of BWRA. The 1960s saw significant growth in the size and scope of BWRA, including its involvement in training.^[[5]] In general, these activities complemented those of the Institute of Welding but it became apparent that the two organisations would serve industry better by merging. The scessor to DSIR, the Ministry of Technology, put forward no objection so a merger was agreed and a new body – The Welding Institute – was created on 28 March 1968.

These earliest years were the foundation of The Welding Institute and what would later become TWI Ltd.

Withdrawal of Government funds

Direct support from Government departments ceased in the 1970s, but TWI not only survived this funding crisis but grew rapidly. The original individual professional membership envisaged in 1922 developed into a body of more than 7000 engineers.

Expansion worldwide

In 1988 Bevan Braithwaite was appointed as chief executive of The Welding Institute. By 2008, the organisation had opened offices and laboratories at three further sites within the UK (in Middlesbrough, Port Talbot and the Advanced Manufacturing Park, South Yorkshire) and operated facilities in the North America, China, Southeast Asia, India and the Middle East.

In 2012, it launched the National Structural Integrity Research Centre (NSIRC) for postgraduate education.

By 2015, TWI had established a further UK base in Aberdeen and 12 international branches.

In 2016, TWI formed the Tipper Group—" a group designed especially for women in the engineering profession." It aims to support and inspire female engineers in welding, joining and associated technologies.

In February 2019, Aamir Khalid was appointed Chief Executive of TWI (the successor to Christoph Wiesner).
