Abstract

A method of welding erosion resistance metallic material is a method of welding erosion resistance metallic material to a base element () of a turbine blade leading edge portion (A). The method includes the steps of: forming a curved surface in the leading edge portion (A) to which the erosion resistance metallic material is applied so that a radius R of the curved surface is larger than thickness t of the base element (); and welding the erosion resistance metallic material to the leading edge portion (A).
