  • Patent number: 6447631
    Abstract: A process for joining components and assembly units of rail-borne vehicles by bonding is described, in which the use of an adhesive, which produces fatigue strength but cures more slowly, is combined with the use of an adhesive that ensures sufficient strength for handling in a short time, wherein complicated design of the bonded joints as well as the need for a large amount of devices are to be avoided, manufacturing tolerances are to be equalized, and defined minimum bonded gap widths are to be maintained. Furthermore, the wetting by the adhesive shall be limited to selected joining surfaces, without having to remove and dispose of the edge limitation.
