A couple of questions?
What is your goal? Testing to certify students, wanting to test welders in industry, testing for businesses? Structural, high pressure ?
It is fairly expensive in comparison to having someone do the testing for you if you are only looking at a few students per semester.
The info from AWS is easily ordered, just give them a buzz.
Other options include; contacting local businesses and seeing if they would be willing to share in the cost. Also, often your local welders union will have a portable testing lab which you can use. Just some thougths.
