<p>PCT No. PCT/DE88/00239 Sec. 371 Date Jan. 12, 1989 Sec. 102(e) Date Jan. 12, 1989 PCT Filed Apr. 20, 1988 PCT Pub. No. WO88/08353 PCT Pub. Date Nov. 3, 1988.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.</p> |
