Description of the Related Art Conventionally, when imparting abrasion resistance to a portion where abrasion resistance is locally required, such as a cutting edge or a ripper point, as disclosed in, for example, Japanese Patent Laid-Open No. 2-6097. It is practiced to form a build-up layer having a composite structure composed of a metal matrix (soft base material) and hard particles on the surface of a member by a build-up welding method. In this case, the following various methods can be adopted in order to include hard particles in the overlay when forming the overlay. Hard particles are directly charged into a molten pool composed of a welding base material. A rod-shaped build-up welding material in which hard particles are enclosed in a tube made of a welding base material is supplied into an arc or flame. Perform submerged arc welding using granular flux and hard particles.
