Abstract
The invention relates to a method of securing an apparatus part in a hole (5) in a metal base plate (1), adjoining peripheral areas (5a, 7a) of the hole (5) and of the part (7) being fused to one another by melting adjoining material portions of the base plate (1) and the part (7) by means of a parallel beam of coherent light (laser light), a mandril (15) being introduced into the hole (5) in which the part (7) is to be secured in a precise orientation relative to the x, y and z axes of the base plate, which mandril (15) is introduced in the exact x, y and z orientation relative to the base plate (1), the edge (5a) of the hole being upset in the mandril direction or z-axis direction at a plurality of peripheral areas of the hole which are equispaced along the 360 angular degrees of the edge (5a) of the hole, as a result of which a protective layer (3) on the base plate (1) is broken up or removed by mechanical deformation in the fusing area prior to fusing, so as to expose the bare metal in the fusing area, the mandril (15) being replaced by the part (7) to be secured, upon which the light which serves for fusing impinges directly on the exposed metal, melts this metal and fuses with the equally molten surface area (7a) of the part (7) between the supports (21) formed by upsetting at the peripheral areas of the hole and the part (7).
