This is for a sculpture I'm working on. I'm planning on cutting out the shapes, shaping them on the english wheel, then attaching them together. I'd love to completely weld every seam, but it'll more likely be several tacks.

if it matters, I'm using oxy / acet for the work.
Use a respirator with zinc cartridges and use a wire wheel to remove the zinc. Since the material is thin, try tacking them to a backing plate.
