One or two, no idea.
Many? Roller burnisher.

Neither ball sizing or roller burnishing is appropriate for thin
tubes.
I was waiting to see the wall thickness before commenting, based on
industry practice rather than my own experience, but I either missed
it or it hasn't been stated.
We did a lot of roller burnishing when I was at Wasino. You need some
resistance to make it work. I don't think it would iron out a weld
seam, regardless. It's used to size and to flatten the peaks of the
bore's surface finish.
Similarly, ball sizing. Unless those tube walls are quite thick, I
can't see it ironing out a weld seam. It probably would just locally
stretch the tube, unless the tube has very thick walls. That doesn't
seem likely if it's seam-welded.
