WELDING TUBES IN MULTI-CHAMBER CELLS

A multi-chamber bladder is comprised of a plurality of stacked bladder sheets including at least a first bladder sheet, a second bladder sheet, and a third bladder sheet, wherein the first bladder sheet and the second bladder sheet have aligned chamber holes, and wherein the third bladder sheet encloses one end of the multi-chamber bladder. A tube is positioned between the second and third bladder sheets such that one end of the tube extends outward of an outer perimeter of the plurality of bladder sheets. A single attachment interface attaches the tube and the outer perimeter of the second and third bladder sheets together.
