Kurt.. I'm an aerospace guy as far as Mil-Spec experience
Two fusion welding mil-specs are Mil-std 1595a which has been superseeded by AWS D17.1 Fusion welding for aerospace stuff. Another Mil-spec that is still in force for aerospace is Mil-Std 2219... D17 may someday superseed 2219 but it hasn't happened yet.
There are some other posters on the forum that have been involved in contract work on armor plate for military vehicles, which may be more up your alley than the aerospace stuff.. I hope they pick up on this thread and chime in on some of the things you might find to be helpful.
Here is a link to a forum thread that focused on armor plate and has a few clues as to where you might look for some beginning help.
http://www.aws.org/cgi-bin/mwf/topic_show.pl?tid=4247Here is the army training manual for welding (TC 9-237) It is nothing cutting edge.. But it is chock full of good information, much of it may be good for what your doing now.. Much of it will be good to help your CWI studies.
Hope this helps and keeps you busy for a while..
Stay with us when you can.. There are lot's of posters on this site who would appreciate the opportunity to serve you!
