<p><P>PROBLEM TO BE SOLVED: To provide a cutting method of brazing wire capable of safely cutting the tip of the wire with high accuracy without depending on mechanical cutting and minimizing cost required for facilities. <P>SOLUTION: In the wire cutting method for continuously delivering the wire 11 supplied from a wire supply machine 14 to an irradiation point P of a laser beam La through a contact tip 12 and for allowing a delivering end to be applied to laser brazing to be fused, an air nozzle 20 is arranged in a wire cutting area which is set adjacent to a brazing area, and a laser torch 10 is positioned such that the laser irradiation point P is arranged close to the air nozzle 20 by action of a robot arm 18. The tip of the wire is fused by the laser beam La while the wire 11 is delivered from the contact tip 12, compressed air is blown to a laser irradiation side from the air nozzle 20 to scatter a melt, and the tip of the wire 11 is shaped and the projecting length of the wire 11 from the contact tip 12 is made constant. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
