Physical aspects of arc welding: Proceedings of seminar in honour of J.F. Lancaster, 1 September 1993, Glasgow (U.K.)

This volume contains the papers presented at a seminar held in honour of Prof. J.F. Lancaster on 1 September 1993 in order to mark the occasion of his retirement as Chairman of Study Group 212 (Physics of Welding) of the International Institute of Welding. Prof. Lancaster was Chairman of Study Group 212 from 1965 to 1992. During the long period of his chairmanship he was the driving force behind the many activities of the Study Group. He organised numerous meetings, stimulated many discussions on a variety of topics within the area of physics of welding and succeeded in bringing and keeping together a group of experts in the field from many different countries. He made Study Group 212 what it is today: a unique scientific forum for the physics of welding. The theme of the seminar was 'Physical aspects of arc welding' and the papers presented cover the following topics: gas tungsten arc diagnostics, cathode phenomena in gas tungsten arc welding, the influence of ambient pressure on the arc welding process, arc ignition behaviour in gas metal arc welding, electrode melting in arc welding and weId pool behaviour. The members of Study Group 212 offer this volume to Prof. Lancaster in recognition of his stimulating activities in the field of physics of welding over a period of many years
