That design holds fine. Welding is not necessary for structural integrity. In fact, with some of those bars it could be disadvantageous, considering the heat influenced zone of steel at some places in the structure, where it would partially recrystallize and thus weaken the material.
The advantage to bolting is that it's fast and cheap, plus if one bolt fails, the rest stays, if a crack appears in a weld, it enlarges fast if under strain. And there's another thing called strain hardening you might want to check into.
i understand heat can weaken metal but in this time the welding done was stick welding and stick welds get covered in slag during with welding process,
crystallized metal is oxidized metal that has been exposed to oxygen before it harderns, the flux on the weling rod melts into slag to prevent such a thing from happening,
there for weaking wont and souldnt happen.
also the buildings were made to withstand winds that high up so they were made to withstand the stress.
theres also something called tensile strength thats something thats alittle more important then just strain harding.
I know more about metals then you may think.

If it met the standards of the rest of the civil engineers, yes.
What does your welding experience have to do with the page linked?
meaning i know what a print or design sould have on it.
