Lyn, I am curious as to how you pre weld your seams before you use a heat gun on the seams! Do you first. Weld them with a mini Iron over a curved surface then go over the whole tube seam again with the gun and roller?
Thanks.

I weld them with a Jingda iron, but just by laying the tube pieces flat and facing together. Imagine that you’re sewing the pieces together, so you add a seam allowance of 7 mm or so to each end of each tube piece and then, instead of sewing, you weld them on that seam allowance. This is where Alpacka sew theirs. You end up with a hull that’s fully together and airtight (except that the floor seam is open) but has no real strength until you weld the seam tape on the outside.
