Definitions
- the components to be joined together are, in particular, the pipes of the exhaust system, through which the exhaust gas flow is guided, for example, from the exhaust manifold to a catalytic converter or a silencer.
- the pipes of the exhaust system through which the exhaust gas flow is guided, for example, from the exhaust manifold to a catalytic converter or a silencer.
- such components have always been connected by a weld.
- comparatively much base area for, for example, an automatic welding machine or a welding robot is required for carrying out the method.
- the components to be welded must be moved relative to the welding head. Therefore, expensive devices for fixing the components to be welded at high dynamic load are required. These devices have a relatively large footprint in the welding booth and for their storage.
- the EP 1 061 240 A2 describes a method for joining components of exhaust systems by arc brazing. It is stated there that induction soldering of exhaust systems is disadvantageous.
- an exhaust system is provided with a first component and a second component, which is characterized in that between the two components, an induction soldering is present, which consists of a high-temperature solder material.
- This object is also achieved by a method for connecting a first component of a motor vehicle exhaust system to a second component, in which the two assembled and provided with a high-temperature solder material components are heated in the region of the solder material by means of an inductor to a temperature above the melting point of the solder material lies.
- the invention is based on the surprising finding that, contrary to the prejudices in the art, a high-temperature solder joint withstands the stresses that act on a motor vehicle exhaust system.
- solder joint is out of the question.
- the maximum allowable operating temperature of soldered components has generally been considered to be around 200 ° C, even when working with a high temperature solder (see, for example, the Draft Specification DVS 938-2 "Arc Soldering" of the German Welding Association of October 2002, which describes exhaust systems an operating temperature for soldered connections up to 180 ° C is specified and a use of solder joints at temperatures of over 180 ° C is expressly not recommended).
- the invention overcomes this prejudice, as the Applicant has found in experiments that soldered components can be exposed to temperatures of over 600 ° C for longer periods without affecting the mechanical stability of the solder joint.
- Favorable to the high temperature strength of the solder joint has the additional effect that sets after the solidification of the soldering material, a reflow temperature, which is higher than the initial melting temperature. The reason for this has not yet been finally clarified.
- One reason could be that certain alloys evaporate when the solder material melts.
- Another reason could be the diffusion of atoms of the base material into the solder material.
- the two components can be connected to one another with less effort and less space requirement than is the case when using a welding method. It is not necessary that the two components are bypassed in the region of their connection by a robot in the circumferential direction. Instead, the connection area between the two components can be accommodated in a compact protective gas chamber.
- the dynamic strength of the solder joint is higher up to a certain temperature, which is lower than the operating temperature occurring at exhaust systems, as compared to a welded joint, since no abrupt changes in stiffness are produced.
- the two components can be formed with a smaller wall thickness, if they are soldered together instead of being welded.
- one of the components has a support surface for solder. This makes it possible to arrange the solder in the vicinity of the soldering gap, so that the solder material, once it has melted, is drawn into the soldering gap by capillary forces.
- the support surface prevents the solder material from running away from the soldering gap and towards other areas of the component. On the one hand, the solder material would be undesirable there for optical reasons, and on the other hand, this solder material would no longer be available for the actual solder joint.
- the bearing surface on the component can be formed with little effort by a circumferential bead, on which the solder ring can be arranged.
- the solder support in the region of the solder joint which has the support surface for the solder material.
- This embodiment has the advantage that the component itself does not have to be reshaped to form the support surface.
- the Lot 100 consists of a material which is electrically non-conductive, for example of a ceramic material. This has the consequence that the solder support is not inductively heated during induction soldering, so that the solder material does not connect to the Lot aggregate. This can therefore be easily removed after soldering the two components.
- an outlet region is provided between the two components, in which excess solder is received without having connected to the two components.
- the discharge area thus acts in the manner of an overflow container, which is then filled when the soldering gap is completely filled with the solder material. It is envisaged that the outlet area does not heat to soldering temperature during soldering so that the solder material begins to solidify as soon as it enters the outlet area. This ensures that the solder material does not escape again on the side facing away from the soldering gap and leads to undesirable solder drops in the interior of the two components. Such a drop of solder could lead to damage during operation of the exhaust system inside.
- two components 10, 12 are shown, which are here two tubes of an exhaust system for motor vehicles. It should be noted at this point, however, that in principle also components other than tubes can be interconnected, e.g. Funnels with tubes, funnels with housings, etc.
- the first component 10 is designed with a constant cross-section, while the second component 12 at the end, which faces the first component 10, on the one hand with an outwardly facing bead 14 and then to the bead 14 with a male portion 16 is executed.
- the insertion portion 16 has an outer diameter that is slightly smaller than the inner diameter of the first component 10.
- the component 10 facing, aligned perpendicular to the central axis M surface of the bead 14 forms a bearing surface 18 on which a ring of solder material 20 is arranged.
- the solder material thus lies in the region of a soldering gap, which is formed between the insertion section 16 of the second component 12 and the first component 10.
- the solder material 20 is a copper-based or nickel-based high temperature solder.
- solder can of course be provided in other forms, such as sheet metal strip, paste, etc.
- a soldering device 22 Around the area to be soldered of the two components 10, 12 around a soldering device 22 is arranged, which consists essentially of two shells 24, 26th exists, which enclose the area to be soldered approximately gas-tight. Within the shells 24, 26, a protective gas atmosphere can be generated by a suitable device (not shown). Extending around the two shells 24, 26 is an inductor 28 which generates eddy currents in the region of the portions of the two components 10, 12 to be soldered together and in the solder material 20, which are converted into heat due to the electrical resistance.
- the ring of solder material 20 is arranged on the bead 14 of the second component 12 in a first step. Then, the second component 12 is inserted with the insertion portion 16 in the first component 10. Subsequently, the two shells 24, 26 closed around the portion to be soldered of the two components 10, 12, and in the interior of the two shells, a protective gas atmosphere is formed. Then, the portions to be soldered together of the two components 10, 12 and the solder material 20 are heated by means of the inductor 28 to a temperature which is of the order of 1000 ° C.
- solder material 20 melts, so that it is drawn by capillary forces against gravity in the soldering gap between the two components 10, 12 and completely fills it.
- the support surface 18 on the bead 14 ensures that the solder material 20, when it melts, does not run away from the soldering gap, but is drawn into the soldering gap.
- it could also be soldered lying or at an angle.
- the two shells 24, 26 can be opened, and the now interconnected components can be removed.
- the soldering device is ready to receive the next components.
- the particular advantage of the soldering device and the induction soldering process carried out with it is that very short processing times are possible.
- the achievable process time for welding two components, including heating and cooling, is on the order of 40 seconds unlike welding, regardless of the seam length. Thus, with a small footprint, a high output can be achieved.
- FIGS. A second embodiment is shown in FIGS.
- the same reference numerals are used, and reference is made to the above explanations in this respect.
- the difference from the first embodiment is that the bearing surface 18 is not formed on one of the components themselves, but on a Lot inventory 30, which is here designed as a closed ring.
- the solder support is made of an electrically non-conductive material, such as a ceramic material, and surrounds the second component 12 adjacent to the soldering gap. In other words, the first component 10 is pushed onto the second component 12 until it bears against the solder support 30. This makes it possible to use the solder support 30 as a reference in the positioning of the two components 10, 12 relative to each other.
- the surface of the solder support 30 facing the first component 10 then forms the contact surface 18 on which the ring of solder material 20 is arranged.
- waves, noses or grooves may be provided, which facilitate the solder to flow under the end face of the component 10 into the soldering gap.
- FIGS. 6 to 8 a third embodiment is shown. Again, the same reference numerals are used for the components known from previous embodiments.
- the support surface 18 is formed on a funnel-shaped flared end portion of the second component 10.
- the ring of solder material 20 thus lies directly between the first component 10 and the second component 12.
- the soldering gap between the first and the second component 10, 12 is formed so that a discharge region 32 for the liquid solder material is trained.
- the outlet area is determined by the fact that it lies outside the area of the two components 10, 12 heated by the inductor 28 and therefore also remains during the actual soldering process at a temperature which is below the solidification temperature of the solder material 20.
- the area of the soldering gap is heated by the inductor.
- the solder material 20 As soon as the solder material 20 has melted, it is drawn into the soldering gap by the capillary forces, in which it wets the surface of the two components 10, 12.
- the solder material reaches the lower section of the soldering gap with respect to FIG. 7, it emerges from the actual soldering gap and enters the outlet region 32. Since this is at a temperature which is lower than the solidification temperature of the solder material 20, the solder material solidifies in the outlet region 32.
- the outlet region 32 is chosen to be sufficiently long to prevent the solder material from the lower side of the soldering and / or into the interior of the two components 10, 12 occurs.
- FIGS. 9 and 10 show a fourth embodiment of the invention.
- a receiving chamber 34 is provided, within which the solder material 20 is arranged.
- the solder material 20 does not have to be arranged here as a completely circumferential ring. It is sufficient that the solder material, for example, extends only along half of the circumference of the annular receiving chamber 34. Once the solder has melted, it spreads due to the capillary forces along the entire circumference of the solder gap, so that a circumferential and gas-tight connection between the two components is made.
- FIG. 12 shows the components known from FIG. 11, wherein, in contrast to FIG. 11, the longitudinal axis of the two components 10, 12 is arranged vertically instead of horizontally. Therefore, the end face of the extension of the second component 12 serves as a support surface 18 for the solder material 20th
- a sixth embodiment is shown.
- the difference from the preceding embodiments is that no tubes are soldered together, but two housing parts of a muffler, a catalyst or other component of an exhaust system.
- the first component 10 forms the upper shell of the housing
- the second component 12 forms the lower shell of the housing.
- Both components are provided with a circumferential edge, wherein the edge of the second component is provided with a circumferential bead, so that together with the edge of the first component, a chamber for receiving the solder material 20 is formed.
- all components of an exhaust system can be connected to each other with the method according to the invention. It is irrelevant whether the components are soldered successively, in groups at the same time or all at the same time. It is also possible to solder different materials together. For example, end pipes, which are made of non-ferrous metals and thus made of a different material than the actual exhaust pipes, are soldered to the exhaust pipes.
