Abstract

I feel deeply honoured for being invited by the Indian Institute of Welding (IIW) to deliver the prestigious Prof.Placid Rodriguez Memorial Lecture. This is a great occasion to recall the fond memories of a renowned metallurgist, eminent scientist and technologist Prof.Placid Rodriguez and his contribution to advancement of science and technology in general and to welding fraternity in particular. This occasion becomes more unforgettable as it coincides with the Golden Jubilee Celebrations of the Indian Institute of Welding. I humbly accept this award and profusely thank the President, Hon.Secretary General, Chairman-Technical Committee and Council Members of IIW for bestowing the honour upon me and the Chairman and Managing Committee members of IIW Hyderabad Branch for having nominating me. The topic I have chosen for this lecture is on welding of ultrahigh strength steels, which is of great importance as these steels are being widely employed in aerospace and defence applications.
