  • Method for laser fusion cutting without cutting gas
    Patent number: 8222565
    Abstract: A method for laser fusion cutting of a metal workpiece including applying a laser beam to the workpiece, where a kerf is melted in the workpiece by the laser beam and a laser beam diameter in a working point is configured to expel molten material from the kerf without cutting gas.
    Type: Grant
    Filed: March 16, 2011
    Date of Patent: July 17, 2012

  • Fixing Adhered Workpieces
    Publication number: 20100071835
    Abstract: A method for fixing adhesive-bonded includes directing an energy beam upon two or more workpieces and thereby causing localized evaporation of an adhesive disposed therebetween within an effective zone of action of the energy beam; and maintaining a vapor channel in a weld pool within the effective zone of action of the energy beam during the evaporation of the adhesive for releasing gas generated during the evaporation of the adhesive. The adhesive has an evaporation temperature that is less than a melting temperature of a material of the workpieces. The adhesive has a viscosity that substantially inhibits an ingress of the gas generated during the evaporation of the adhesive.
