1. A process for the laser beam machining of components, the process comprising:

  • providing a remote laser head;

    guiding the laser head with a manipulator with a multiaxial manipulator hand, said remote laser head being arranged externally on said manipulator hand, said laser head emitting a laser beam;

    during welding or cutting, guiding the emitted laser beam along a welding or cutting path on the component by orientation modifications and with a variable irradiation angle β

    , the guiding including changing the orientation of the laser beam only by pivoting motions of the manipulator hand about at least one of the hand axes resulting in a changing of irradiation angle of the laser beam; and

    changing and adjusting at least one or more of a laser power output of the emitted laser beam and a velocity of welding or cutting as a function of the changing irradiation angle β

    of the laser beam.
