  • Method and a device for thermal surface-hardening of metal workpieces
    Patent number: 5096511
    Abstract: The invention concerns a method for thermal surface-hardening of metal workpieces, in particular of shaft ends, by means of a laser source with which, if necessary, with relative movement of workpiece and laser source, the workpiece surface to be hardened is heated sectionally by laser radiation. In accordance with the invention, the laser radiation is irradiated essentially uniformly in a hardening zone that extends in a principal direction, at least approximately over the entire workpiece surface to be hardened.
