Definitions
- the present invention relates to a method in which two parts by means of a
- Electron beam welding CMT arc welding, especially when joining non-similar materials, eg. As aluminum / steel, to form intermetallic phases in the molten bath, whose nature and thickness is difficult to control, but
- the object is achieved with a method in which two parts are joined together by means of a weld and in which the two parts are fixed during welding by a magnet, wherein the magnetic field of this magnet influences the flow of a melt in the weld.
- the parts to be joined are fixed, in particular held together and / or connected to each other during the thermal joining by a magnetic force, so that a between the parts to be joined
- the magnetic force is preferably made available over a very large area, so that sets a constant small gap between the parts to be joined.
- the magnet providing the magnetic force may be a permanent magnet or an electromagnet.
- a permanent magnet or an electromagnet.
- At least one electromagnet used whose field strength is adjustable.
- this part can be attracted directly by the magnet.
- the other part to be joined then becomes placed between this ferromagnetic part and the magnet.
- the magnetic field of the clamping device is now used simultaneously to influence the flow in the molten bath and thus to influence the local composition and / or the local metallic structure of the resulting weld.
- the magnetic field can be used to homogenize the molten bath, and / or to influence the divergence / convergence.
- the magnetic field is used to achieve a very specific concentration and / or microstructure gradient in the molten bath and thus in the resulting weld. This allows the quality, d. H.
- the resulting weld can be specifically influenced.
- the magnetic field does not serve to prevent the running away of the melt.
- the quality, i. H. the local chemical composition and / or the local microstructure, the resulting weld can be specifically influenced.
- the method according to the invention is suitable for joining two parts made of different materials, for example aluminum and steel. With the method according to the invention can be achieved very uniform, well reproducible connections between the parts to be joined.
- the magnetic field is changed during welding.
- the change may relate to the strength of the magnetic field and / or its direction.
- the magnetic field extends over the entire length of the weld.
- the influence of the magnetic field on the melt is interrupted only when it is sufficiently solidified, ie, if its structure is so far frozen that it no longer or only slightly changed.
- the invention will be explained with reference to the single FIGURE 1.
- Figure 1 shows a welding jig by means of which a first part 2 and a second part 3 are connected to a weld 6.
- the first part 2 is, for example, an aluminum sheet and the second part 3 is a steel sheet.
- the sheets 2, 3 are designed as very thin sheets. These two sheets are pressed together with the clamping direction 4, which is magnetically provided according to the invention, preferably over a large area, so that during welding by means of
- Welding device 5 for example the laser, only a smaller, more uniform
- the clamping device 4 consists in the present case of a magnet, in particular an electromagnet, and a ferromagnetic clamping piece, which is attracted by the magnet and thereby the parts 2, 3rd
- the ferromagnetic clamping piece By the energy input during welding, for example by a laser 5, the first and / or the second part 2, 3 are at least partially locally, in the region of the subsequent weld, melted, so that a molten bath 6 is formed. According to the magnetic field of the magnet 4 will now be used to a flow in the
- the local composition and / or the local structure of the resulting weld can be influenced. It is preferably not provided that the magnetic field prevents or reduces loss of the weld pool.
- the magnetic field of the magnet 4 can be changed during the welding process. For example, during the welding process, the strength of the magnetic field can be reduced or increased.
