Hi BPI1!
If you want to know about the AWS structural welding codes for steel and stainless steels, then go ahead and read away but, I seriously do not think you're going to find anything enlightening with respect to applying the optimal welding parameters, shielding gas parameters or anything else that will guide you in depositing the best welds possible using the aforementioned forms of GMAW methods of metal transfer.

If you want to find information about how to achieve the best GMAW deposits with various methods of metal transfer through process control without all of the sales hype, then I strongly suggest that you visit Ed Craig's:
http://www.weldreality.com Take a journey around his site and you'll see why most of us here have such respect for the experience and, knowledge this man has to offer when it comes to just about everything one wants to find out about how to deposit optimal welds through process control knowledge!!! :)
I'm not going to give you any other suggestions because, I really do'nt need to anymore!!! Especially since I've pointed you in the direction where you need to be so, enjoy your journey into Ed's world!!! :) :) :)
Respectfully,
Henry
