| 摘要 |
<p>The invention relates to a method in connection with a laser machining apparatus, whereby during laser machining (LT), carried out by the apparatus, nitrogen (N2) is being used as shielding gas, which is produced by means of a so called nitrogen generator (1), such as membrane-, PSA-separator or like, which separates nitrogen gas from a gas flow being treated therewith. Machining gas (TK). which is being generated during laser machining (LT) that is protected by shielding gas, is being used as the gas to be processed by the nitrogen generator (1).</p> |
