Gas Shielding of the Welding Arc-Some Aspects

Abstract

I consider it a great honour for me to be singled out this year for giving this Memorial lecture on this important occasion and to so distinguished a gathering of welding technologists of this country. The honour is doubly great because this lecture is instituted in memory of Keith Hartley with whom I was privileged to be associated for many years in the course of my working life and also in the course of work we were doing for this Institute.
