CONSTITUTION: A welding-bead peening device of a bellows pipe comprises a frame(20), a support unit(30), a roller unit and a horizontal moving unit(40). The support unit is horizontally connected to the frame. Welding beads are located on the bottom of the support unit. The roller unit is installed on the frame. The roller unit is located on the upper part of the welding bead of a molded pipe. The roller unit presses and makes the welding bead flat. The horizontal moving unit is installed on the frame. The horizontal moving unit horizontally moves the roller unit.
