Lawrence really nailed it in terms of what to look for. You don't mention any experience in the field as a lot of times people will go back to school to learn a new process or get certs which he mentioned.
AS far as two schools, Ferris State in Big Rapids MI, and Washtenaw Community College in Ann Arbor both have excellent programs and facilities. I might be biased because I graduated from WCC last year, but it's considered one of the best AAS welding programs in the nation. I can't speak to any other schools in other states you mention but if you want additional information I can provide quite a bit about WCC.
as lawrence mentioned schools and programs have slightly different focuses, an AAS with a focus on robotic welding won't help you pass pipe certs and visa versa. Also degrees are usually pretty general, just enough to get your foot in the door but chances are you'll be taking additional cert tests on positions and joints you never practiced in the classroom, as there are just soo many possible configurations.
Good luck it's a great field to be in, PM me and I can give you loads more information about WCC and AAS degrees as I've been there and I'm working on my B.A.S now
