Welding structure used for assembling thin-wall fish scale cylinders

The utility model discloses a welding structure used for assembling thin-wall fish scale cylinders. The welding structure comprises the thin-wall fish scale cylinders (1) and is characterized in that a liner thin steel plate (2) is welded to the inner side of the welded position of the ends of the two thin-wall fish scale cylinders (1), and after fixing the two thin-wall fish scale cylinders (1) together, the liner thin steel plate (2) is used for welding a gap between the ends of the two thin-wall fish scale cylinders (1) so that the thin-wall fish scale cylinders (1) can be assembled. As the two thin-wall fish scale cylinders are aligned accurately by welding the liner thin steel plate, the integral strength of the thin-wall fish scale cylinders is improved, welding joints can not be seen after the thin-wall fish scale cylinders are installed, and the attractiveness of the thin-wall fish scale cylinders is improved; in addition, as annular ribs are arranged, the phenomenon that due to high-temperature firing in the welding process, girdling possibly occurs can be further eliminated, and the strength of the thin-wall fish scale cylinders is improved; the welding structure is easy to operate, the excessive demands on the proficiency degree of workers are reduced, and the welding structure is suitable for application and popularization.
