Hello Firstpass!!!
American Technical Publishers (ATP) has some good material that's just what you're looking for, and their prices are reasonable.
If you got this month's welding journal, you'll find some info about what they have to offer in the AWS Product Literature Review brochure that accompanied the journal... You'll find it on page two, in the top right shown as: "Welding and Metallurgy Training Materials"...
In case you did'nt recieve one yet, ATP has a website @:
http://www.go2atp.com
You'll find what you're looking for and more in the website...
I've got to ask you this, have you checked out the AWS's own publication entitled: "Welding Metallurgy"??? I ask this because, this book is an excellent book, and also a good reference for the students in the future...
Just a thought...
Anywho, I'll look for some more leads because, as an instructor myself, I did alot of research locating multiple sources of training materials, and have kept many of them for future reference...
When I compile a list of resources, I'll send them to you via e-mail, and/or post them for anyone else that's interested...
Also, I'm sure that there are other instructors here that have resources to share with you...
Respectfully,
SSBN727 Run Silent... Run Deep!!!
P.S. ATP also has some interesting .pdf files that also may be of interest in their "Resources" link... Also, they offer some good material for teacher education that you might find interesting...
