Between two joining partners to be joined, the molded part is placed, wherein the cross section of the molded part is adapted to the geometry of at least one of the joining partners. For this purpose, the molded part is connected in a form-fitting manner to the at least one joining partner before welding, so that subsequently the two joining partners are connected to one another by welding along the molded part with force and form fit.

  • Velocity fluctuations also lead to a non-reproducible weld material composition.
  • different weld compound compositions occur in the area of the seam root and the seam flank.
  • So-called molded parts can replace the wire during laser beam welding as welding filler material. These molded parts simplify the welding process while increasing process reliability. Such a molding design depends largely on the shock configuration.
  • the object of the invention is therefore to use the use of moldings on fillet welds, overlapping or parallel joints so that process reliability and thus a higher reproducibility of the welding or soldering process is given.
  • overlapping and parallel thrust does not require a symmetrical geometry of a molded part during welding.

It is important to ensure that the predetermined breaking point is designed so that both mold halves do not deform plastically during the separation process.
  • Such a molded part is formed so that it preferably has an approximately triangular outer shape, which is interrupted by a stop surface, which is a bearing surface. Due to the stop surface on the molded part, the position of the welding filler material is clearly defined at the joining partner.
  • At least one of the joining partners has one Material reduction in the area of the fillet weld to be executed.
  • the molded part is inserted or inserted, so that the molded part with its contact surface with the material reduction, which may be formed as a step or recess is in contact.
  • a lateral edge of the joining partner with the material reduction is pressed against the stop surface of the molded part.
  • the support surface prevents the molded part from slipping before and during the welding or stapling process. This is achieved in particular by a clamping device, which clamps the joining partners with the partially intermediate molded part before stapling or in the actual welding process with each other. Such positioning avoids speed variations of the wire feed, with the result that different weld metal compositions are not present in the present process.
