Joining method, joining appliance and fastening element

摘要

A method for joining a fastening element on to a surface portion of a component, the fastening element having an adhesion face, on to which there is applied an adhesive that is thermally meltable and thermally settable, comprising the steps of:
pre-heating the adhesive to a first temperature (T1), in order to activate the adhesive;pre-heating the surface portion to a second temperature (T2); andplacing the adhesion face on to the surface portion;

the adhesive undergoing main heating, to a third temperature (T3), after the adhesion face has been placed on to the surface portion, in order to set the adhesive and thereby permanently fasten the fastening element to the component.

1. A method for joining a fastening element on to a surface portion of a component, the fastening element being held in a holding device of a joining tool and having an adhesion face on which is applied an adhesive that is thermally meltable and thermally settable, comprising the steps of:
pre-heating the adhesive via a first heating source to a first temperature (T1), in order to melt the adhesive; pre-heating the surface portion to a second temperature (T2) via a second heating source separate from said first heating source; activating the joining tool to move the holding device so that the adhesion face of the fastening element is placed on to the surface portion; thereafter performing a main heating of the adhesive at a third temperature (T3) in order to set the adhesive and thereby permanently fasten the fastening element to the component; and thereafter activating the joining tool to release the fastening element from the holding device; wherein the pre-heating of the adhesive and the preheating of the surface portion are effected with an overlap of time.
