I venture to guess that both types of frames are made both ways.

Both materials exist at virtually all points in the market, from the
cheapest department-store junk to signed-by-the-welder bespoke jobs. I'm
pretty sure the technology to robo-weld either material is available,
too. Aluminum is supposed to be a bit trickier to weld from what I hear,
but both materials require expertise when they are as thin as high-end
bicycle tubing.
