Zusammenfassung:	A tooling and method for flexible through connection of a double-liner water heater. The tooling includes a transition shaft, a tooling connecting plate and a fastening screw. The method includes: allowing a shaft head of the transition shaft to be in fit with an inner surface of an outer flange of a lower liner for welding; allowing an end hole to be in fit with an outer surface of an inner flange of an upper liner for welding; after welding seams are cooled, removing the tooling, and enameling the upper and liners; forming through-flexible connection between the inner and outer flanges; and firmly fitting the upper and lower liners together with two steel strips to ensure that a gap between the upper and lower liners is not greater than 7 mm.
