| WO2006045431 A UPAB: 20060526 NOVELTY - The method involves emerging a laser beam (2) from a cutting head (3) comprising a cutting nozzle with an inner edge (4). The axis of the beam is displaced in relation to a workpiece along a cutting line with a fixed orientation in a cutting direction of the workpiece. A position of the cutting head is modulated with regard to its temporal average value, or the laser power and gas pressure in the cutting head are modulated. USE - Used for cutting materials. ADVANTAGE - The position of the cutting head is modulated with regard to its temporal average value, or that the laser power and gas pressure in the cutting head are modulated, thus avoiding unwanted broadening of cut joint due to high laser power and formation of adhering beard due to small cutting speed. | |||||||||
