18 or 20 gauge sheet steel. A conical roller really helps, but a straight roller and some hammer work will produce an okay cone. Butt weld the seam on the cone. Try for a very good fit and use a small torch tip (1 or 0) to fuse the joint, then planish the joint after welding.
Don't consider MIG welding. If you have a TIG and want to use it, fine, but with some practice (I did it for 10 hours a day for some months), an oxyacetylene torch works better. I have both, and wouldn't fire up the TIG for pipe work.
Is the entire barrel iron? If so, you might want to limit your excursion into performance land. More power results in more heat, and an iron barrel can't shed the heat as quickly as an aluminum barrel with a sleeve (not even going to talk about plated aluminum).
Please don't tell Mom I'm a pilot. She thinks I play piano in a whorehouse.
