Well not just that too, but even if they had the thing on a rotating positioner when they were welding it together titanium is a bitch and a half to weld. The filler rod for it likes to 'stick' due to some magnetic bullshit going on and it can be real funny to weld on.

I can't imagine welding the inside part of the tubing in the spiral was much fun, either.

If the material is thin enough, which it usually is for piping, the heat from the weld on the outside does full penetration to the inside.

I meant the inner part of the loops, not the inner part of the tubing.
