Metarinka,
Hello. Yes, I was at FABTECH all four days.
Monday, I was in the presentation on the 'Education Annual Program' from 8-5. The first two on 'Using Practical Welding Metallurgy Object Lessons' by Larry Zirker and 'Common Errors in Applying ANSI/AWS A2.4 Welding Symbols' which actually was presented by David Hernandez were the most interesting of these to me personally. But I stayed all day taking notes and appreciating the presentation given to educators and career counsellors on the opportunities within welding careers. I wish other members of this forum, who have been really negative about welding as a career choice, could have been there. I wanted to bring this type of info back to AZ and especially to the high schools and colleges I am working with on their advisory committees.
Tuesday, I walked the show floor and sat in on the D14.3 and later D14 main committee meetings to see what happens in code committee meetings and if I wanted to get involved.
Wednesday, I was in the WPS seminar all day with Dr Scott Helzer. Pretty good but needed to go a lot further. I don't feel it lived up to it's advertising nor it's listed objectives in the 'Official Guide and Directory' for the show.
Thursday I went to the Professional Program presentation on 'Materials Weldability' in rm N139. The first one at 8:00am was read by Dr. Alexandre Queiroz Bracarense of Federal University of Minas Gerais. I read that one for some students who were not able to attend. It made some good points and conclusions about preheat and hydrogen in regards to cold cracking.
But, after Dr. Boian Alexandrov of Ohio State gave a presentation, also on Hydrogen Assisted Cracking in Dissimilar Metal Welds', Dr. Bracarense read a paper of his own research into 'Impermeable Low Hydrogen Covered Electrodes' and what they are trying to do in developing new electrodes that will not need to be kept in rod ovens. They start with lower hydrogen than our current 7018 and stay at those reduced rates even when left in atmosphere for 2-3 MONTHS.
Now, this would be quite a development indeed. And their procedures also required less energy to manufacture making them a very energy (read 'GREEN') saving product.
ANYWAY, I was just curious as to rather the good Prof. Crisi knew this guy or not.
So, to get to both of you in one post, hope you see this Professor. That is his full name and the school if I got my info correct.
Have a Great Day, Brent
