Definitions

  • the invention relates to a fillet weld on an overlapping or parallel joint between a first and a second joining partner using a molded part which is used as welding filler. Furthermore, the invention relates to a method for producing such a fillet weld using a molded part.
  • a filler metal is used in the laser beam welding.
  • This filler metal is usually used as wire or tape.
  • the positioning, feeding and introduction of this welding filler material is very difficult. Complicating the introduction of the welding filler in the case is still when small focal lengths must be used, because, for example, the space is designed to be very small or angled. It is therefore necessary that in such a case for verification, a control system with a sensor with regard to the feed rate and positioning of the welding filler material is required.
  • DE 10 822 16 A shows that runs between to be welded together strip edges with a welded thin, metallic profile strand, at least on the inside of a shell on both sides of the Weld is provided with projections to cover the seam.
  • the object of the invention is to improve the welding or soldering of fillet welds on lap and parallel joints so that a
  • the molded part is designed as a welding filler material and is thus always available in a defined amount and the same composition during the welding process.
  • the molding is placed in regions between the joint partners to be joined and thus is available in a defined amount at each point of the weld.
  • the molded part is formed so that it preferably has an approximately triangular outer shape, which is interrupted by a stop surface, which is formed at an angle to a support surface. Due to the stop surface on the molded part, the position of the filler metal weld material is clearly defined.
  • At least one of the joining partners has a material reduction in the region of the fillet weld to be executed.
  • the molded part is inserted or inserted, so that the molded part is in contact with its bearing surface with the material reduction, which may be formed as a step or recess.
  • 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 slipping of the molded part before the welding or stapling process. This can be achieved in particular by a tensioning device, which braces the joining partners with the partially intermediate molded part prior to stapling or in the actual welding operation. As a result of this positioning, speed fluctuations of the wire feed are eliminated, which also results in that the present method does not record different weld material compositions.
  • FIG. 1 is a view of a dumping of a molded part between two joining partners, which are connected to a fillet weld;
  • FIG. 2 shows a second view of a design of a shaped piece in a perspective illustration
  • Fig. 3 is a third view of a fillet weld in a cross section after

  • Form part 3 has been introduced.
  • the material reduction 4 is dimensioned such that it is of the same order of magnitude as the molded part 3 in this dimension
  • the molded part 3 has formed in this area a support surface 5, which is in contact with the material reduction 4. On the opposite side of the support surface 5, a base surface 8 of the molded part 3 is present.
  • a tensioning device not shown, the joining partners 1 and 2 are pressed or clamped together with the intermediate therebetween molding 3 before the welding process, to prevent slipping of the molded part 3 in the welding process.
  • the molded part 3 still has a stop surface 6, which is directed against an edge 12 of the joining partner 1.
  • the molded part 3 is reproduced again in a separate representation. It can be seen that the molded part 3 has approximately a triangular shape which is interrupted in a region of the bearing surface 5 and the stop surface 6 which is angled towards it. In the area of the stop surface 6 and the bearing surface 5, an interruption 7 in the form of a recess or a concavity is present. This interruption 7 allows, for example, an edge of the joining partner 1, as can be seen in FIG. 1, to protrude into this region of the interruption 7.
  • the welding process is such that, prior to the actual welding operation, the joining partners 1 and 2 are combined with the correspondingly placed molded part 3, as can be seen for example in FIG. 1, and clamped or pressed against one another by means of a suitable clamping device.
  • the clamping device By the clamping device, the molded part 3 can not leave its position during the welding process or the stapling process.
  • a remelting of the welding filler material is achieved, so that a non-positive and positive connection in the form of a fillet 11 between the joining partners 1 and 2, as can be seen in Figure 3, arises.
  • the welding nozzles can be omitted and, moreover, a complicated control system in the form of sensors for checking the wire feed is not necessary.
  • the optimization of the fillet 11 is increased in terms of their properties such as strength, ductility, corrosion and hot cracking.
  • This proposed method or the use of a molded part in a fillet weld 11 is particularly suitable when using aluminum or aluminum alloys.
  • the molding is made of AIMgX or AISiX or the like.
