1977 Portevin Lecture Welding, a Subject for Teaching and a Means of Teaching

It is because I devote an important part of my time to the teaching of welding that I have chosen it as the nbject of this lecture in memory of Professor Albert Portevin, a lecture which the Executive Council of the rtW did me the honour of asking me to prepare. It is also and above all because Albert Portevin was himself a teacher, my own and that of many others, that I had the idea of devoting this lecture to an activity in which tie shone during his whole career, in particular at the Ecole Centrale des Arts et Manufactures, the Ecole Superieure de Fonderie and the Ecole Superieure de Soudure Autogene.
