certified aircraft with welded aluminum frames?

That is a pretty broad statement.

Parts are made from any materials that the manufacturer
desires/specifies. Wood, aluminum, brass, glass and anything in between.
That includes 6061 of all tempers.



That is kinda what I thought. I'd like to find some specific examples
of certified aircraft parts made from 6061. I took a gander at
Aircraft
Spruce's online catalog, but the search function isn't set up for
that.

I'm thinking that certified metal props will probably be 6061 too.
