Mathematical modelling of weld phenomena 6 PDF

INTRODUCTION

The Sixth International Seminar on Numerical Analysisof Weldabilitywasheld during October 2001, again at Schloss Seggau near Graz, Austria. This location worked its magic again to provide an inspiring environment for friendly discourse and intellectual debate between scientists from many parts of the world. The conference proved once more to be a vigorous forum for the science and technology of welding.

The conference is biannual, organised by the IWS of the Technical University of Graz and the working group on the numerical analysis of weldability of commission IX of the International Institute of Welding. The meeting has a unique tradition of publishing: all the articles refereed, edited and typeset for uniformity; each article is required to be comprehensive in its content, a feature which is atypical of conference proceedings in general. Hence the large number of citations of all the preceding volumes in the series.

A new feature of the sixth seminar was the 'Kenneth Easterling Best Paper Award' sponsored by the IWS in commemoration of the first chairman of this seminar the late Professor Kenneth Easterling. Following what was perceived to be a fair and full selection procedure, the award was given to V. Kharkhin et al. for their novel contribution on the inverse modelling of welds, a technique which apparently has its origins in rocket science!

It is the intention that this award should become a permanent feature of future meetings, both to honour the contributions of Kenneth Easterling and to encourage the best scholarship in our search for reputable welds. It was also decided at the meeting that there was a need for a materials database covering information of the kind vital in weld modelling; following a survey of opinion, the concept has been launched as an international activityunder the auspices of the IIW.

The seminar took place in the aftermath of the tragic events of 11 September. It was nevertheless attended by 135 participants from 27 countries. In his opening address, Dr FelixWallner used a quote which underlined the need for people to work together rather than engage in conflict through ignorance, and he expressed delight at the example set by the conference delegates. His address is reproduced below.

Our sincere gratitude to all those who participated in the seminar and associated events, and who worked towards a better understanding of welding phenomena. We thank also the local organisers who with their warm welcomes and endless patience made things work. They are now preparing the seventh meeting to be held from 28 September to 1 October 2003 at Seggau/Graz. We especially thank Ernst Kozeschnik for taking charge both of the organisation and of the publication of these proceedings. We particularly appreciate the work of Peter Danckwerts and his team at Maney Publishing. Their work is reflected in the high production-quality which has typified the series as a whole.
