  • Joint method
    Patent number: 11958138
    Abstract: A joint method includes a groove formation step of removing part of a first projection and part of the second projection to form a groove region between the first projection and the second projection, a first welding step of joining a first member and a second member to each other by butt welding, and a second welding step of filling the groove region by buildup welding. The groove formation step forms a first inclined surface in the first projection facing the groove region to be gradually distant from a joint position joined with the second projection so as to be closer to an outer surface of the first projection, and forms a second inclined surface in the second projection facing the groove region to be gradually distant from the joint position joined with the first projection so as to be closer to an outer surface of the second projection.
