ABSTRACT:
In the construction of cylindrical tanks having end domes wherein the domes are attached by stir friction welding, a wagon wheel is placed inside the tank at the interface of the tank cylinder and the dome such that it provides backup support for the pressure exerted by the stir friction welding tool and strengthens the weld area and the tank by being welded into the tank by the stir friction welding process.
