  • the invention relates to a fastening element which can be placed on a component having a metallic surface and which has a metallic rotationally symmetrical end face and forms by rotation under pressure against the component.
  • Such a solder joint is disclosed in DE 198 03 392 Al. It is a Reiblötthetic between two plastic parts, namely a lid and a bottom part. To connect these two parts together, they each receive a metallization layer, wherein also in the region of the connection point a coating with the solder is provided.
  • the connection to the two parts is made by a frictional movement, which may be formed as a circular movement, wherein the solder is melted by friction and thus the Reiblötitati is produced.
  • the presentation in the cited document is kept very general, without being addressed to any specifics, how to make the surfaces to be joined together of the relevant components and the solder can be effectively brought to effect in a meaningful way.
  • the end face is provided with radially extending beads which scrape the surface along the beads during rotation and when pressed against the component, and the solder is pressed in the form of individual pieces in depressions in the end face next to the beads, that liquefiable or plasticizable solder fills the interstices between the beads as a solder film by means of friction heating.
  • the safety of a solder joint depends on the surface wetting of the components to be joined with the solder, which is ensured here by the surface of the component being scraped off during rotation when the end face provided with the solder is pressed against the component, whereby any foreign bodies are scraped off , in particular oxide layers, are removed and the metallic surface of the component is freely available for soldering.
  • the beads not only the effect of scraping is achieved by the beads, but also a uniform distribution of the liquefied or plasticized solder over the end face and thus over the counter surface of the relevant component, whereby the solder, which essentially the space between the beads as Soldering film fills in its solidification, can form a secure connection between the component and fastener.
  • the time required for the actual Reiblötvorgang effort is relatively low, since the solder on the one hand finds a clean surface when heated by friction and is also held in a uniform thickness between the radially extending beads, so that the existing solder is optimally utilized.

  • the attachment of the solder can advantageously take place in such a way that it can be secured as a single piece in a central depression of the end face is pressed.
  • the solder When heated by friction, the solder is then plasticized or liquefied and migrates into the area next to the beads, where it then comes into contact with the metallic surface of the component and then leads to soldering.

  • These driving elements then ensure that in the Reiblötvorgang one hand, the individual pieces taken during rotation and on the other hand not a whole piece of the solder can be torn out of the depression and thus possibly missing for the Reiblötvorgang.

In both cases, moreover, there is the possibility of giving the nut or the bolt a flange which is particularly suitable for being used for the friction-soldering process.
