You sound like you're making this stuff up.
Tig welded with either shielding gas or in the best case in a vacuum chamber.

The limiting factor with advanced steel alloy is wall thickness and the "beer can effect".
Yes and? Were we not discussing strength? Now it's suddenly frame weight. You can do things with aluminum you can't do with steel. You can do stuff with carbon fiber you can't do with steel. None of that is new. But steel is still stronger than aluminum. Yet strength isn't everything or we'd be making frames out of UHMWPE.
