parts assembly forming an angle therebetween and method of obtaining this assembly

The parts 2, 4 are provided with pads 6, 8, 10, 12 intended to be connected by means of welding elements made from a metallic material with low melting point, the sealable timber, the surface of each stud being wettable by the material in the molten state, whereas their environment is not. The studs of one of the parts are coated wafers 10, 12 of material of the same thickness but of different volumes; the pads of the other part are placed on the corresponding wafers; the wafers are brought to the molten state, their thickness, their volume, their spacing and the surfaces of the pads being chosen so that the parts then form between them a determined angle. Application to the manufacture of mirrors .
