  • Laser brazing improvement with twinspot
    Patent number: 7875827
    Abstract: The present invention provides a method for laser brazing a first member to a second member using a laser brazing head. The laser brazing head has means for generating a first laser beam and a second laser beam. The method comprises the steps of: arranging the first member in contact with the second member such that a junction is formed there-between; providing a filler material in the vicinity of said junction, and passing the laser brazing head along the junction such that the first laser beam melts the filler material to at least partially fill said junction to form a brazed joint. The second laser beam then effects a post heat treatment of the brazed joint.

  • Lasercutting With Scanner
    Publication number: 20090039060
    Abstract: The embodiments described relate to a laser cutting method suitable for cutting multilayered or painted materials such as for example car bodies. The method involves the step of scanning a low laser beam a plurality of turns along an intended cut edge. Utilizing the described cutting method, the paint located in the vicinity of the cut edge is only slightly affected by the heat generated by the laser beam.
