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.
Claims21
A method for fixing adhesive-bonded workpieces, the method comprising:
- 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,
- wherein the adhesive has an evaporation temperature that is less than a melting temperature of a material of the workpieces, and
- wherein the adhesive has a viscosity that substantially inhibits an ingress of the gas generated during the evaporation of the adhesive.
A method for fixing adhesive-bonded workpieces, the method comprising:
- applying an adhesive between a pair of workpieces;
- directing an energy beam upon the workpieces and thereby forming a point of material engagement between the workpieces;
- and
- maintaining a vapor channel in a weld pool in an effective zone of action of the energy beam during the formation of the point of material engagement,
- wherein at least part of the adhesive situated within the zone of action of the energy beam evaporates and gas generated by the evaporation of the adhesive escapes through the vapor channel during the formation of the point of material engagement, and
- wherein the adhesive has a viscosity that substantially inhibits an ingress of the gas generated by the evaporation of the adhesive during the formation of the point of material engagement.
