Definitions

  • the invention relates to a method for manufacturing of spark plugs with central and body electrode (s), which with Precious metal inserts are armored.
  • the object underlying the invention is in specifying a method of the type mentioned at the beginning, quickly and economically with high manufacturing reliability can be carried out.
  • the center electrode has a preferred one Embodiment of the invention a pyramid-shaped Tip (round pyramid) 9, with the base diameter of the Tip 9 has the diameter d.
  • a welding electrode 3 is arranged in the end face a precious metal ball 2, in its most preferred embodiment consists of iridium / iridium alloy, stored is; it also has a diameter of d.
  • the usual spark plugs have a diameter d in the range of 0.4 to 1.0 mm, in particular from 0.6 to 0.8 mm.
  • the noble metal ball 2 in the End face of the center electrode is embedded in that the pyramid-shaped center electrode tip 9 on the precious metal ball 2 is pressed and liquefied, the Material of the tip 9 flows around the precious metal ball 2 to the extent in which they are not in the end face of the welding electrode 3 is embedded; Precious metal ball 2 is preferred about half sunk in the end face of the welding electrode 3 stored.
  • the Body electrode (s) 8 the spherical precious metal reinforcement 2 be introduced.
