News in brief - May/June 1999

Connect, no. 100, May/June 1999, p.7

Inaugural meeting of Group Sponsored Project

- Polythionic acid stress corrosion cracking (PASCC)

A successful launch meeting was held on 24 March to address the issues of susceptibility to PASCC of materials currently being used in refineries and those which may be used in modification /new build.

Industry representatives welcomed the concept of the project. TWI will prepare a detailed proposal incorporating input from industry which will be discussed during the inaugural meeting at TWI on Thursday 24 June 1999. For further details or discussion, please contact Andrew Leonard.

Solid state joining today

The E.O.Paton Electric Welding Institute of the National Academy of Sciences of Ukraine, and TWI are organising a symposium to provide an update on exciting new developments in, and applications of, solid state welding processes. This will take place 13-14 September 1999 at TWI. Solid state processes make it possible to join materials, and combinations of materials which are otherwise difficult or impossible to weld. In many cases the joint cycle time is very short compared to other processes, leading to economic advantage.

This event will bring together speakers from both organisations and from industrial end users, and will cover developments in friction welding, flash butt welding, MIAB, explosion welding, and other solid state processes and will include plastics and fibre reinforced plastics (FRP) technologies as well as metals. Further details can be obtained from the Meetings Section. Email:

Friction stir welding on display

Registrations are now coming in to TWI for the world's first major International Symposium dedicated exclusively to friction stir welding (FSW). The event brings together speakers from all corners of the globe who have hands-on experience of the process. Friction stir welding, invented by TWI and patented in December 1991, is arguably the biggest advance in welding aluminium alloys since the invention of MIG (GMAW).

In the short space of 7 years, over 35 companies have been licensed to use the process, and more than 150km of production welding, for applications from ships to spacecraft, have been made. Meanwhile, the research community is extending the scope of the process by working on FSW of steel, titanium, and other materials, as well as looking at an ever wider range of applications.

The Friction Stir Welding Licensees Association is supporting this event, which will be held at the Rockwell Science Center, Thousand Oaks, California, USA, on 14, 15 and 16 June 1999. Full details, brochure, and enrolment form can be obtained from Diana Fairmaner.

Welding and Joining 2000

A call for papers has gone out for this International Conference - New Materials and New Perspectives - to be held in Tel Aviv 19-20 July 2000. Bevan Braithwaite, Chief Executive of TWI, is a member of the International Organising Committee of this Conference being run by Israeli materials and welding organisations and sponsored by international welding societies.
