Hi Fusion and Welcome,

If this link does not work, you can go to AWS.org and under "publications" it will take you to global's web site where you can search for AWS A2.1 for the wall charts. I'm sure they will charge for them. However there may be some references to those symbols on the web. Try searching for "welding symbols". Another AWS publication that is handy to have is AWS A2.4 which gives lots of insite to the symbols and their meanings. AWS A3.0 is the Standard for terms and definitions.
Hope this helps,
John Wright
