yes, WW i am aware of your numerous nuclear certs since you never miss an opportunity to remind the reader of the fact that you possess them. in this case you might take a moment to read the posts on this thread. no nuclear welder's here just a group of poster's that believe that chemical alchemy is going to make their welds look better. the post and photos were for illustrative purposes only; you do not have to kill yourself with acids and cleaners to get a decent weld in place but you will have to take the time to practice welding. in most cases a ss brush and some acetone is all you'll ever need; if that. you are a little detached from the reality of working in non nuclear environments. perhaps a little time in a hack shop would suit you well. WPS? don't make me laugh.
