Hi full metal inspector!
First off,
"WELDCOME TO THE WORLD'S GREATEST WELDING FORUM!!! :) :) :)"Now, nobody said there isn't a standard or code regarding your application which you have chosen to be rather sketchy regarding the details involved that IMHO, does not constitute any serious violations regarding national security that I'm aware of!!! :) :) :)
Seriously though, there are building codes that are to be followed if this is a structural application and I don't know if this will be helpful, but I'm posting some links to websites that have info which may be indeed helpful to answering your query... So let me start with this one:
