4 th International Symposium on Friction Stir Welding

Park City, Utah, USA, 14-16 May 2003

The International Friction Stir Welding Symposia, organised by TWI on behalf of the Friction Stir welding Licensees Association, are now recognised as the leading forums for debate on this topic, as they cover all industries and materials, and all aspects of friction stir welding and related technologies.

The 4 th Symposium, held in the spectacular mountain surroundings of Park City, Utah, lived up to expectations, and drew the largest number of delegates yet (160), despite reservations on travel caused by terrorism, the Iraq war and SARS. The event was co-hosted by Brigham Young University, whose efforts to provide a really first class venue were appreciated by all.

The response to the Call for Papers was so great that for the first time there were a number of split sessions, allowing 51 papers to be presented within the three days of the event. The approach of presenting process development papers in single sessions, and more specialised topics such as modelling, FSW of steels and specific industry-focused papers in split sessions worked well. There were also 12 poster presentations.

The event has reverted to the initial format of 30 minute presentations, giving a much more generous presentation time for authors and audience alike, allowing more detailed presentations to be made. The presentation periods were separated by generous breaks, allowing ample time for the all-important networking processes to take place, and it was clear that full advantage of this was being taken by the delegates. The social event at Robert Redford's Sundance resort (generously sponsored by MegaStir Inc) provided more networking opportunities, accompanied by great food and a backdrop of truly spectacular mountain scenery, and even a lunar eclipse at no extra charge!

A number of companies exhibited their products during the symposium, and this was appreciated by the delegates, and will be a feature of future events - if possible on a larger scale.

Many technically significant presentations were made, and it is unfair to single out specific contributions. However, the rapid pace of progress in friction stir welding of steels and stainless steels was perhaps most forcibly illustrated in a group of six papers from various authors. Steel is not yet welded commercially by this process, but it is clear that there is now strong interest in achieving this objective.

Other specialist sectors also reported considerable recent advances, including applications in aerospace, weld modelling, machine design, NDE, microstructural development and others, thus demonstrating significant progress over a very broad front.

The Proceedings are available on a CD-ROM, and represent an invaluable source of data. Non-registrants may obtain this CD-ROM from the Library at TWI ( library@twi.co.uk) for £150 (+ VAT for UK purchasers). Look for our special offer on acquiring the proceedings of earlier symposia.

The 5 th Symposium will be held in Metz, France between 14 and 16 September 2004, and this event will be co-hosted by the Institut de Soudure - further details will be posted on TWI's website as they become available.
