摘要：
A radial pin 2 has a second end portion 2B protruded from an outer surface of a turbine casing 1 and a first end portion 2A inserted into a through hole 3 formed in the turbine casing 1, and a weld bead 4 is formed on a periphery of the second end portion 2B. A weld bead cutting device 10 has a cutting portion 12 which cuts the weld bead 4 formed on the periphery of the radial pin 2, and a support portion 20 which supports the cutting portion 12 on an end surface 2C of the second end portion 2B of the radial pin 2 such that the cutting portion 12 is movable along the periphery of the radial pin 2.
