Abstract

PURPOSE: To improve brittle fracture and fatigue strength by build-up welding the surface of a material to be welded with the 1st welding material then further build- up welding the same with the 2nd welding material of a coefft. Of linear expansion smaller than that of the 1st welding material.
CONSTITUTION: After the surface of a material 1 to be welded is build-up welded by the 1st welding material 2, the surface of the material 2 is build-up welded by the 2nd welding material 3 of a coefft. of thermal expansion smaller than that of the material 2. Therefore, the degree of shrinkage deformation of the material 2 is smaller than that of the material 3, and is governed by the deformation of the material 2. As a result, compressive residual stresses are generated in the material 3.
