Seamless tube does not have a seam at all. That tubing is created by piercing a hole into a solid round bar of steel.

very interesting, John...I have seen a lot of butt strap boilers with gas welded seams that had the straps rivited on for the structural strength. As far as I know, no traction engine maker used a forged or fusion welded seam.
