Abstract: Two components (42, 44) are bonded together by placing a layer of braze filler metal between and in contact with the faying surfaces, and then directing a high energy beam (46) through one of the components, through the faying surfaces and the layer of brazer filler metal, and into the second component so as to form a melt-through weld bond (53) centrally located between two braze bonds (54, 55). Relative movement between the high energy beam and the components can be provided so that the high energy beam is always perpendicular to the portion of the faying surfaces in which the weld bond is currently being formed. The two components can be an impeller disc and an impeller cover.
