Postupak u skladu sa zahtjevom 1, naznačen time što je laserska zraka koja međusobno zavaruje individualne ploče (E) vođena pod oštrim kutem uz rubove ploča koji se trebaju zavariti.2. The method according to claim 1, characterized in that the laser beam that mutually welds the individual plates (E) is guided at a sharp angle along the edges of the plates to be welded. 3. Postupak u skladu s jednim od prethodnih zahtjeva 1 ili 2, naznačen time što je struja plina primijenjena na područje zavarivanja za vrijeme postupka zavarivanja.3. The method according to one of the preceding claims 1 or 2, characterized in that the gas current is applied to the welding area during the welding process. 4. Postupak u skladu sa zahtjevom 3, naznačen time što se struja plina upuhuje.4. The method according to claim 3, characterized in that the gas stream is blown. 5. Postupak u skladu sa zahtjevom 3, naznačen time što se struja plina tvori primjenom podtlaka.5. The method according to claim 3, characterized in that the gas stream is formed by the application of negative pressure. 6. Postupak u skladu sa zahtjevom 3, 4 ili 5, naznačen time što je korištena struja plina struja zraka ili struja intertnog plina.6. The method according to claim 3, 4 or 5, characterized in that the gas stream used is an air stream or an inert gas stream.
