Description

Technical Field

[0001] The invention relates to a method for producing a side wall for a drawer, the side wall comprising at least one carrier profile at least partially made of metal material and at least one hollow profile at least partially made of metal material, wherein the at least one carrier profile and the at least one hollow profile are welded to one another by means of at least one laser welding connection. The invention also relates to a side wall for a drawer, the side wall comprising at least one carrier profile and at least one hollow profile, wherein the at least one carrier profile and the at least one hollow profile are at least partially formed of metal material and are welded to one another by means of at least one laser welding connection. The invention also relates to a carrier profile for such a side wall. The invention also relates to a configuration system comprising at least one laser and at least one such side wall. Background Art

[0002] From the prior art, side walls for drawers are known which comprise a hollow profile and a carrier profile made of metal, wherein the carrier profile and the hollow profile are connected to one another by means of a laser via a laser welded connection.

[0003] A disadvantage of the prior art is that, for a safe and appropriate laser welded connection, while at the same time retaining the functionality of the carrier profile as a container rail, the location of the laser welded connection must be positioned deep in the carrier profile and that the location of the laser welded connection is difficult to access for the laser due to its structural dimensions, especially in the case of narrow carrier profiles. As a result, the laser must be arranged outside the carrier profile at a certain distance from the laser welded connection, resulting in the laser being emitted at an unfavorable angle and at a large distance from the material to be welded. Due to this unfavorable angle, a large amount of laser light provided for the laser welded connection is at least temporarily reflected during the welding process, so that the laser intensity and energy are lost before they are used and, in addition, undesirable heating (possibly with deformation) occurs on the areas of the side wall that are not provided for the laser welded connection. In the case of an inappropriate laser welded connection, the service life of the drawer is reduced and there is the risk of the carrier profile being undesirably loosened from the hollow profile during use of the side wall. In addition, a visually flawless appearance of the laser welded connection is essential, since otherwise the impression is given that the side wall is not safe for use under load. Summary of the invention

[0004] Therefore, the objective technical task of the present invention is to provide a method for manufacturing side walls, a side wall, a carrier profile and a configuration system that are improved compared to the prior art, in which the disadvantages of the prior art are at least partially eliminated, and the outstanding advantages of the method, side wall, carrier profile and configuration system are in particular the reduction of the laser power required for the laser welding connection and / or the improvement of the quality of the laser welding connection and the increase in the strength of the side wall.

[0005] This object is achieved by means of the features of claim 1 .

[0006] Accordingly, according to the present invention, it is provided that the at least one carrier profile and / or the at least one hollow profile has at least one pressed portion in the area of ​​the at least one laser welded connection and / or around the area of ​​the at least one laser welded connection before welding, for increasing the energy absorption of the laser of at least one laser to form the at least one laser welded connection, and for at least partially melting the at least one pressed portion during the welding process.

[0007] This makes it possible for the first time to design the side walls, in particular the at least one carrier profile and / or the at least one hollow profile, to be particularly narrow, thereby making it possible to produce a drawer with increased storage space that is particularly aesthetically pleasing.

[0008] Furthermore, the at least one laser welded connection can be arranged particularly deep in the side wall or the at least one carrier profile, whereby the side wall can be adjusted particularly flexibly to specific requirements. Limiting factors of the welding process, such as proximity to the at least one laser or an angle of incidence of the laser on the welding point close to a right angle or a straight line, can be significantly reduced by the at least one embossment and can be easily adapted via the specific shape or geometry of the at least one embossment.

[0009] In the prior art, the at least one laser must also be operated particularly close to the side wall and / or with high laser power in order to be able to generate the energy input necessary for melting the material despite reflections. In particular, due to this, the sensitive and expensive optics of the at least one laser become contaminated and the focusing of the laser beam is particularly complicated for focusing. In the present invention, the distance and / or the laser power of the at least one laser can be optimally adjusted so that the at least one laser can also be protected from contamination.

[0010] The at least one embossment ensures that the laser beam of the at least one laser can strike the side wall in essentially any design for welding at essentially a right angle. The at least one embossment can significantly reduce the degree of reflection of the laser light provided for welding and, moreover, effectively suppress heating next to the at least one laser welded connection.

[0011] By increasing the energy absorption at the desired welding point, energy of the at least one laser can be saved and damage due to defective laser-welded connections can be prevented.

[0012] In addition, the positive effect can be achieved that the side wall can be loaded in the region of the at least one laser welded connection and a greater load can be applied to the drawer front wall or drawer rear wall. This can be advantageous, for example, when the panel tilt adjustment is performed via a rail, wherein the range of applications such as size optimization is widely spread.

[0013] Typically, the at least one stamping can be completely melted during the laser welding connection, wherein the at least one stamping is preferably only partially melted. In other words, an edge region of the stamping can remain around the at least one laser welding connection, for example in order to be able to orient the at least one laser with reduced precision and / or to exclude undesirable reflection effects in the edge region of the stamping.

[0014] As mentioned at the beginning, protection is also claimed for a side wall for a drawer, which side wall comprises at least one carrier profile and at least one hollow profile, wherein the at least one carrier profile and the at least one hollow profile are at least partially formed from a metal material and are welded to one another by means of at least one laser welded connection, wherein the at least one carrier profile and / or the at least one hollow profile comprises at least one pressing portion in the area of ​​the at least one laser welded connection and / or around the area of ​​the at least one laser welded connection for increasing the energy absorption of the laser of at least one laser to form the at least one laser welded connection.

[0015] For example, the at least one stamping can serve as an indicator of the intended position of the at least one laser-welded connection, an indicator which can preferably be recorded automatically and / or by a camera system.

[0016] The number of embossings and / or the positioning of the at least one embossing can be adapted to the parameters of the side wall, such as load-bearing capacity, dimensions etc.

[0017] The at least one carrier profile can be in the form of a container rail, which can usually be used to connect a side wall to a drawer bottom.

[0018] The at least one hollow profile can be in the form of a frame cap, which can generally be used to arrange at least one retaining device for a drawer rear wall or a drawer front wall at least partially within the at least one hollow profile.

[0019] The side wall is particularly preferably a drawer side wall, a container side wall or the like. Preferably, it is a drawer with a drawer front wall, a drawer rear wall, a drawer bottom and two such side walls, wherein the holding device is provided for fixing the drawer front wall and / or the drawer rear wall to the side wall.

[0020] Preferably, the at least one carrier profile and / or the at least one hollow profile is provided in a preliminary method step, preferably via rolling and / or bending.

[0021] As mentioned at the beginning, protection is also claimed for a carrier profile for such a side wall, wherein the carrier profile is at least partially formed from a metal material and is characterized in that the carrier profile, in particular on the inner side facing the interior space of the carrier profile and / or on at least one side strip pointing in the vertical direction when the carrier profile is in use, comprises at least one embossing for increasing the energy absorption of the laser of at least one laser in order to form at least one laser-welded connection with at least one hollow profile.

[0022] For example, the embossing can be arranged along the side strips and / or on the side strips on the inner side and / or on two side strips, preferably oriented parallel to one another, of the carrier profile and / or hollow profile.

[0023] As mentioned at the outset, protection is also claimed for an arrangement comprising at least one laser and at least one such side wall, wherein, in order to introduce the at least one laser-welded connection, in particular in such a way, the at least one laser is oriented with a laser emission opening at an acute angle, preferably an acute angle of 15° to 30°, particularly preferably 20° to 25°, relative to a vertical direction in the use state of the at least one side wall, so that the laser light can be emitted, in particular directly and essentially at a right angle, onto the flank of the at least one embossing.

[0024] This ensures positive properties, namely that the at least one laser does not have to be operated too close to the side wall and that material-specific properties that differ from those conventional for the furniture industry do not have to be provided in order to increase the energy input at the welding point.

[0025] In particular in the case of narrow side walls or carrier profiles, a connection via riveting is not possible, wherein the carrier profile can be welded using a disk laser, for example.

[0026] During the welding process, the distance between the laser and the side wall is preferably in the range of between 5 cm and 50 cm, particularly preferably between 10 cm and 40 cm, further preferably between 15 cm and 25 cm.

[0027] Advantageous embodiments of the invention are defined in the dependent claims.

[0028] It is particularly preferred that the at least one embossing is arranged on the at least one carrier profile and / or the at least one hollow profile before welding in order to increase the energy absorption of the laser in the region of the at least one laser welded connection and / or around the region of the at least one laser welded connection.

[0029] Since the at least one embossment is a structural element of the side wall, no changes can be made to the at least one laser, such as focus width, intensity, pulse duration, irradiation duration, etc. Use in different lasers with corresponding dimensions and properties is possible.

[0030] According to an advantageous embodiment of the invention, it can be provided that the at least one embossing is arranged on the inner side of the at least one carrier profile facing the inner space of the at least one carrier profile, preferably on at least one side strip of the at least one carrier profile pointing in the vertical direction when the side wall is in use.

[0031] In the case of a laser-welded connection facing the exterior, there are fewer problems with the accessibility of the at least one laser, but even here a particularly advantageous integration into the production cycle can be ensured. Problems with the accessibility of the at least one laser can also be overcome without complex components such as mirrors or split profiles by at least one pressing in the interior.

[0032] Advantageously, it is provided that at least two, preferably exactly three, embossments are provided and / or that the at least one embossment is introduced into the at least one carrier profile and / or the at least one hollow profile in such a way that the at least one embossment

[0033] - in the form of grooves, preferably corrugated grooves, preferably having at least two, particularly preferably at least five, further particularly preferably at least ten ridges, and / or

[0034] - have a substantially rectangular cross-section and / or local arrangement, and / or

[0035] - arranged in the longitudinal direction of the side wall in the region of the free end, preferably at a distance of at least five times the material thickness of the at least one carrier profile, and / or arranged centrally, and / or

[0036] - arranged orthogonally to the longitudinal direction at a distance of at least ten times the material thickness of the carrier profile from the free end and / or arranged along the side strip of the at least one carrier profile in the front third starting from the upper side of the at least one carrier profile arranged in the use state of the side wall, and / or

[0037] - arranged on a side strip of the at least one carrier profile and / or of the at least one hollow profile in the use state of the side wall, and / or

[0038] - a depth of at least one fifth and / or at most half the material thickness of the at least one carrier profile, and / or

[0039] A contact region for the at least one hollow profile and / or the at least one carrier profile is formed on the side of the material facing away from the at least one embossment, preferably in an essentially planar manner.

[0040] The properties of the at least one embossment, such as depth, geometry, shape and / or positioning on the side wall, can be individually adapted to the conditions and / or requirements of the side wall. In the case of varying material thicknesses, the material thickness can be defined, for example, via an average or maximum material thickness. Free ends are usually present both for the at least one carrier profile and for the at least one hollow profile in the vertical direction (for example as the maximum distance along this degree of freedom) and in the longitudinal direction.

[0041] It has proven to be advantageous if the elevations each have two flanks, preferably converging toward each other at their tips.

[0042] - the flanks form an angle between each other in the range of 70° to 110°, preferably substantially a right angle, and / or

[0043] - orienting one of the two flanks relative to the at least one carrier profile and / or the at least one hollow profile in such a way that the normal of the flank leads out of the side wall without contact between the two side strips of the at least one carrier profile and / or the at least one hollow profile, and / or

[0044] - the two flanks have a flank height in the range of between 0.05 mm and 0.2 mm, preferably between 0.1 mm and 0.15 mm and / or at least one of the two flanks has a flank length of between 0.1 mm and 0.25 mm, preferably between 0.15 mm and 0.2 mm, and / or

[0045] The protrusions have a flank angle of between 15° and 40°, preferably between 25° and 30°, relative to the side strips of the at least one carrier profile and / or the at least one hollow profile, and / or two adjacent protrusions are spaced apart from each other by a distance of between 0.2 mm and 0.5 mm, preferably between 0.3 mm and 0.4 mm.

[0046] The properties of the at least one embossing, such as the geometry and / or the orientation of the flanks, can be determined by the laser light of the at least one laser and / or the component dimensions of the side wall, so that the production process of the side wall is particularly efficient.

[0047] According to an advantageous embodiment of the invention, it is provided that the at least one laser welded connection is introduced in the form of a point or line laser welded connection.

[0048] Particularly preferred are spot-shaped welds which extend at least partially within the lateral extension of the at least one embossing.

[0049] It has proven to be advantageous to apply at least one coating, preferably a plastic coating, to the at least one carrier profile and / or the at least one hollow profile, preferably in the region of the at least one embossing, and to remove this coating, preferably using the at least one laser and / or locally, before or during welding.

[0050] The at least one coating can, for example, be provided for a specific visual appearance of the side wall, wherein the at least one coating is possibly undesirable for the at least one laser welded connection and / or - for example via composition and / or coloring - at least temporarily increases the absorption of the laser light at the start of welding.

[0051] The evaporation or removal of the at least one coating before welding with the at least one laser can reduce or remove a certain amount of substances that are harmful to welding, such as organic matrices and / or harmful substances.

[0052] An advantageous variant is that, in order to introduce the at least one laser welding connection, the at least one laser is oriented with a laser emission opening at an acute angle, preferably an acute angle of 15° to 30°, particularly preferably 20° to 25°, relative to the vertical direction in the use state of the side wall, preferably providing that the laser is emitted essentially at a right angle to one of the two optionally present side wings of the at least one embossed portion.

[0053] It is particularly preferred to provide that at least one retaining device at least partially formed of a metal material is provided for connecting the side wall to the drawer rear wall or the drawer front wall, wherein the at least one retaining device and the at least one carrier profile are welded by means of at least one laser weld, and in the area of ​​the at least one laser weld a laser deformation portion separated from the at least one laser weld is induced by irradiation with a laser.

[0054] As a result, an additional laser treatment can be carried out in the region of the weld in order to, on the one hand, further stabilize the side wall and, on the other hand, counteract tearing of the at least one retaining device.

[0055] In other words, during the welding operation for fixing the at least one holding device, heat is additionally introduced into the at least one carrier profile by means of at least one laser. This causes the at least one carrier profile to deform slightly and bend upwards. In other words, stresses are generated in the at least one carrier profile in a targeted manner, which stresses lead to a preferred deformation.

[0056] In the case of certain material qualities, structural changes may also occur and thus initiate a hardening process.

[0057] Due to the additional laser treatment, the at least one carrier profile is more load-bearing, so that higher loads on the drawer rear wall or drawer front wall connected to the at least one retaining device are possible. This is advantageous, for example, when the tilt adjustment of the drawer front wall is achieved via a rail.

[0058] In a preferred embodiment of the present invention, it is provided that:

[0059] - the at least one laser weld is arranged predominantly at a location of the at least one carrier profile at which the at least one retaining device and the at least one carrier profile contact one another, and / or

[0060] - the at least one laser deformation is arranged predominantly at a location of the at least one carrier profile at which the at least one holding device and the at least one carrier profile do not contact one another, and / or

[0061] - arranging the at least one laser deformation portion on the at least one carrier profile offset relative to the at least one laser weld seam, and / or

[0062] the at least one laser deformation and the at least one laser weld are arranged relative to one another in such a way that the laser deformation and the at least one laser weld have at least one intersection point, and / or the at least one laser deformation extends over a greater width in a direction transverse to the longitudinal direction of the side wall than the at least one laser weld, and / or

[0063] The at least one laser deformation is at least partially linearly shaped in the form of a sawtooth, and / or

[0064] - The at least one laser weld seam and the at least one laser deformation are produced by the same laser, and after producing the at least one laser weld seam and before producing the at least one laser deformation, the focus of the laser is adjusted, preferably widened.

[0065] Typically, the same laser can also be used for the at least one laser-welded connection and the at least one laser weld, wherein the laser sequentially processes the locations of the side wall to be processed. Typically, different lasers or a plurality of lasers of the same type can also be used at least partially for the individual heat treatments—for example for different locations along the side wall.

[0066] It is particularly preferably provided that the at least one laser weld seam and the at least one laser deformation are at least partially linear and have different line widths, preferably the laser deformation having a larger line width than the at least one laser weld seam.

[0067] Mutual modifications, the side wall may have the design or structural features of a method claim, wherein the features of a device claim for the side wall can be applied in a similar manner to a method claim. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] Figure 1a A side wall 1 for a drawer is shown, which comprises a carrier profile 2 in the form of a container rail for connecting the side wall and the drawer bottom and a hollow profile 3 in the form of a frame cap for arranging a holding device 4 for the drawer rear wall and the drawer front wall within the hollow profile 3 (see Figure 4b-4d ).

[0076] The carrier profile 2 and the hollow profile 3, which at least partially consist of a metal material, are provided so as to be welded to one another by means of a laser welded connection 5. In order to improve the laser welded connection 5 (see Figure 3a-3d ), the carrier profile 2 comprises a plurality of embossings 6 in the area of ​​the laser welded connection 5 to be arranged on the side wall 1 and around the area of ​​the laser welded connection for increasing the energy absorption of the laser light 7 of the laser 8 to form the laser welded connection 5.

[0077] The stamping 6 is arranged on the carrier profile 2. Alternatively or additionally, the stamping 6 can be arranged on the hollow profile 3.

[0078] Figure 1b and Figure 1a The only difference is that the side wall 1 is viewed from a changed perspective, wherein it can be seen that there are exactly three embossments 6. Generally, the number of embossments 6 is arbitrary, wherein, for example, further embossments 6 can also be arranged opposite to each other on the carrier profile 2 (or hollow profile 3).

[0079] Figure 1c The free ends of the carrier profile 2 in the longitudinal direction 15 of the side wall 1 and in the vertical direction of the side wall 1 are shown, formed by the upper side 18 of the carrier profile 2 arranged in the side wall usage state 17 and the opposite lower edge.

[0080] Along the longitudinal direction 15 of the side wall 1, the embossments 6 are arranged in the region of the free end and centrally on the support profile 2 (hidden in the view) at a distance of at least five times the material thickness 16 of the support profile 2. Orthogonally to the longitudinal direction 15, the embossments 6 are arranged in the front third of the side strip 12 of the support profile 2 from the lower edge of the side strip 12 of the support profile 2 formed in the use state 17 at a distance of at least ten times the material thickness 16 of the support profile 2 and starting from the upper side 18 of the support profile 2 arranged in the use state 17 of the side wall 1.

[0081] The carrier profile 2 has a further side strip 12 oriented parallel to the side strip 12. The stamping 2 is located closer to the top 18 than to the lower edge of the carrier profile in the vertical direction 11, so that due to the structural dimensions of the side wall, producing the laser welded connection 5 without the stamping 6 is complex and difficult.

[0082] The embossing 6 is introduced into the carrier profile 2 (and optionally also into the hollow profile 3 ) in such a way that it has a rectangular cross section with rounded corners, is arranged in a partial area of ​​the side wall and is positioned on the side strip 12 of the carrier profile 2 in the use state 17 of the side wall 1 .

[0083] Figure 1d An enlarged detail of the side wall 1 is shown in the region of the embossings 6. These embossings 6 are arranged on the inner side 10 of the carrier profile 2 facing the interior 9 of the carrier profile 2 - on side strips 12 pointing in the vertical direction 11 in the use state 17 of the side wall 1.

[0084] Figure 2 A particularly preferred embodiment of a carrier profile 2 for a side wall 1 is shown, wherein the carrier profile 2 is made of a metal material and a pressed portion 6 is arranged on an inner side 10 facing an inner space 9 of the carrier profile 2 and on a side strip 12 pointing in a vertical direction 11 when the carrier profile 2 is in use, in order to increase the energy absorption of the laser light 7 of the laser 8 in order to form a laser welded connection 5 with the hollow profile 3.

[0085] The carrier profile 2 has a transverse web 28 which is oriented orthogonally to the two side webs 12 of the carrier profile 2 and, in the state mounted on the hollow profile 3 , is oriented orthogonally to the two side webs 12 of the hollow profile 3 .

[0086] Figure 3a A side view of the side wall 1 is shown together with a sectional view of the side wall and an enlarged detail in the region of the embossed portion 6 or the laser-welded connection 5 .

[0087] The laser welded connection 5 is shown schematically, wherein for illustration purposes the embossing 6 is shown completely in cross section—this is usually not provided in the region of the laser welded connection 5 due to the melting process of the material.

[0088] The laser welded connection 5 as a material-locking connection can be combined with other types of fixed connections between the carrier profile 2 and the hollow profile 3. For example, a screw connection, a nail connection, a clamping connection, a form-locking connection, etc. can be used.

[0089] In the use position 17 , the side wall 1 is oriented for connecting further components of the drawer.

[0090] Figure 3b and Figure 3a The only difference is that the side wall 1 is rotated by 180°. This orientation can be used to assemble the side wall 1, wherein the laser welded connection 5 is produced by emitting the laser 7 from above toward the pressing part 6 located in the interior 9 and between the two side strips 12. However, the orientation of the side wall 1 during the production process is generally arbitrary.

[0091] The depth of the embossing 6 lies between one fifth and one half of the material thickness 16 of the supporting material 2 .

[0092] The embossing 6 is in the form of a corrugated groove 13 , wherein the groove 13 has a plurality of ridges 14 .

[0093] On the side of the material of the carrier profile 2 facing away from the embossing 6 , the embossing 6 forms a contact area 20 which can be used for linear or surface contact between the side strips 12 of the carrier profile 2 and the side strips of the hollow profile 3 for defined contact for the laser welded connection 5 .

[0094] The laser-welded connection 5 can be in the form of a point or line laser weld, for example.

[0095] Figure 3c The system arrangement comprising lasers 8 and side walls 1 is shown, wherein the lasers 8 (in general any number) are oriented with laser emission openings 23 at an acute angle of between 20° and 25° to / towards the vertical direction 11 for the introduction of the laser-welded connection 5, so that the laser light 7 of the laser 8 can be emitted directly at right angles to the flank 21 of the embossing 6 (see Figure 3d )superior.

[0096] A method for producing a side wall 1 can be illustrated as follows: a metal carrier profile 2 and a metal hollow profile 3 are provided, wherein, before the welding process, in order to increase the energy absorption of the laser 7, a pressing part 6 is arranged in and around the region of the laser welding connection 5 on the carrier profile 2, so that the carrier profile 2 and the hollow profile 3 are subsequently welded to each other via the pressing part 6 with the aid of the laser welding connection 5, wherein at least the carrier profile 2 has the pressing part 6 before welding and the pressing part 6 is at least partially melted during the welding process.

[0097] A coating 22 in the form of a plastic coating can be applied to the carrier profile 2 or the hollow profile 3 in the region of the embossing 6 , which coating is at least partially removed by the laser 8 before or during welding.

[0098] To produce the laser welded connection 5 , the laser 8 is oriented with the laser emission opening 23 at an acute angle to the inner side 10 of the carrier profile 2 , wherein the laser light 7 is emitted at a right angle to one of the two flanks 21 of the stamping 6 formed by the stamping 6 in order to melt the metal material.

[0099] Figure 3d The embossing 6 for the laser-welded connection 5 is shown in an enlarged view, wherein it can be seen that the elevations 14 of the grooves 13 each have two flanks 21 converging toward each other at their tips. The radius in the transition region of the flanks 21 caused by production is usually arbitrary.

[0100] The flanks 21 of the groove 13 form a right angle with one another, wherein the ridges 14 of the embossing 6 have a flank angle 31 of 28° relative to the side strips 12 of the support profile 2. The ridges 14 are arranged obliquely with their flanks 21, wherein two adjacent ridges 14 are spaced apart by a distance of 0.36 mm.

[0101] The two flanks 21 form a flank height 29 of 0.125 mm. The two flanks 21 of the elevation 14 have different flank lengths 30, one flank 21 having a flank length 30 of 0.17 mm.

[0102] As in Figure 3c It can be seen that one of the two flanks 21 is oriented in each case relative to the side strip 12 of the carrier profile 2 in such a way that the normal of the flank 21 leads out of the side wall 1 without contact between the two side strips 12 of the carrier profile 2 so that the laser-welded connection 5 can be completed via the embossing 6 with reduced reflections.

[0103] In a similar structural design, a pressing portion 6 may be provided on the hollow profile 3 .

[0104] Figure 4a The carrier profile 2 of the side wall 1 is shown from the bottom side toward the top side 18 (as a plate-shaped component of the carrier profile 2). Figure 4b to Figure 4d In the figures, the dashed-line region of the free end of the carrier profile 2 is shown in different exemplary embodiments for connecting the holding device 4 or for increasing the stability of the holding device.

[0105] Figure 4b It is shown that a holding device 4 for connecting the side wall 1 to a drawer rear wall or drawer front wall made of a metal material is provided and arranged on the carrier profile 2 . The holding device 4 and the carrier profile 2 are welded by means of a laser weld seam 24 .

[0106] Figure 4c It is shown that the connection between the support profile 2 and the holding device 4 has, in the region of the laser weld seam 24 , a laser deformation 25 which is separate from the laser weld seam 24 and which is emitted by the laser 7 .

[0107] The laser deformation 25 is arranged for the most part at locations of the carrier profile 2 at which the holding device 4 and the carrier profile 2 are designed without contact with one another.

[0108] The laser weld seam 24 and the laser deformation 25 are linear in shape, wherein the laser weld seam 24 and the laser deformation 25 have different line widths (during the emission of the laser 7 and after the welding process). The laser deformation 25 has a larger line width than the laser weld seam 24 .

[0109] The laser deformation 25 extends in a direction transverse to the longitudinal direction 15 of the side wall 1 over a greater line width than the laser weld seam 24 .

[0110] Laser deformation 25 is linear and designed in the form of saw teeth 27 .

[0111] The laser deformation 25 and the laser weld seam 24 have a common intersection point 26 .

[0112] Figure 4d It is shown that a further laser deformation 25 is provided, which is arranged offset with respect to the laser weld seam 24 on the carrier profile 2. By means of the laser deformation 25, a hardening process and an increase in strength can be achieved during the irradiation with the laser 7.

[0113] During the production of the side wall 1, the retaining device 4 provided with metal can be welded to the carrier profile 2 by means of a laser weld 24 or a plurality of spatially separated or mutually connected laser welds 24, wherein a laser deformation portion 25 separated from the laser weld 24 is induced in the area of ​​the laser weld 24 by irradiation with a laser 7.

[0114] It is usually not mandatory that the laser weld 24, the laser deformation 25 and the laser welded connection 5 are produced by the same laser 8. For example, only the laser weld 24 and the laser deformation 25 can be produced by one laser 8. In this embodiment, after the laser weld 24 is produced and before the laser deformation 25 is produced, the focus of the laser 8 is adjusted in a manner that widens the focus.
