  • Device for and method of establishing joints by means of laser beams
    Patent number: 4912297
    Abstract: In a device for joining by means of laser radiation, in particular for welding edges, the laser beam travels essentially parallel to the plane of the joint gap and is directed essentially perpendicular to the joint line. To ensure that the energy of the laser radiation is absorbed almost entirely in the region of the joint, the laser radiation is polarized mainly parallel to the plane of the joint gap and/or the laser beam (20) is shaped or focused at right angles to the joint gap (12) in the form of a strip parallel to said gap.
