PROBLEM TO BE SOLVED: To provide a lining support between jointed parts by final friction star welding in aluminum tank assembly. SOLUTION: In the construction of a cylindrical tank 2 provided with an end dome, the dome is mounted by friction star welding, a wagon wheel 10 is positioned inside the tank at an interface between a tank cylinder 6 and the dome 12, and a lining support is fitted against a pressure applied by a friction star welding tool. A welding area and the tank are reinforced by welding it inside the tank by means of a friction star welding process. |
