Definitions
- the invention relates to a joining method.
- the laser beam welding method is known as a joining method in which the energy is supplied to the workpieces or components to be joined via a laser.
- the process is used to weld components that must be joined with high welding speed, narrow and slim welds and low thermal distortion.
- the laser welding or laser beam welding is usually carried out without feeding a filler material.
- non-positive clamping or fixing devices are used for fixing the components.
- a pressure-sensitive adhesive was additionally inserted between the two sheets.
- the method consists of a combination of pressure-sensitive adhesive tape assembly between the two sheets arranged in the lap joint and a subsequent laser beam welding in addition to the pressure-sensitive adhesive tapes.
- the tape was first glued to the surface of a component. Then, the second component was arranged in overlap on the first component and fixed by the present between the components adhesive film. The welding took place afterwards. Due to the immediate adhesion of the double-sided adhesive tapes, the sheets are geometrically fixed.
- An object of the invention is therefore to provide a method with the workpieces such.
- B. metallic or non-metallic films gap-free in a simple manner can be joined together.
- a laser beam welding method is to be provided, with which thin foils or sheets can be joined without gaps to themselves or to other workpieces. It should be dispensed with costly and time-consuming clamping devices - and methods, especially when three-dimensional geometries are to be created.
- the method for gap-free joining of two workpieces is characterized by the steps: a. the workpieces to be joined are brought into contact with each other, so that a joint is formed, b. the joint is geometrically fixed by a film, c. the workpieces are joined together.
- a joint is formed by bringing two workpieces into contact with each other until they overlap or are in the form of an I joint.
- I-jointed workpieces may, but need not be in direct physical contact with each other. Contacting each other in this sense means that the workpieces are brought into contact with each other close enough to ensure that a joint is formed between the workpieces and a joining process with a chance of success can be used to join the workpieces.
- the movie can be continued after step c. be removed from the surface of the workpieces.
- workpiece further includes in particular but not exclusively metallic foils and sheets, and non-metallic workpieces, provided that they are joined with a joining method according to the invention.
- bringing workpieces into contact with each other optionally means that the joint consists of two Ends a single mechanically flexible workpiece, such.
- B. a film can be formed. In the case of a thin film, this may be for the purposes of the invention z. B. are rolled up into a tube, so that two ends of the same film abut each other (I-push) or overlap. As a result, the joint is formed and fixed from two surfaces of a single workpiece.
- step a. and step b. be interchanged.
- step b. before step a. takes place the surface forming a joint of a first workpiece is first fixed and then at least a second workpiece brought into contact with the first workpiece and fixed with the film. It is conceivable and, of course, also feasible to first weld one of the workpieces peripherally on the surface with a film and then to perform step a. perform. The film is then first overlapped on one of the workpieces, and then the second work piece is brought into contact with the first work piece and fixed with the free part of the adhesive film. Other workpieces can be brought in this way in multi-layer impact with each other. There are therefore different approaches to bring the workpieces into contact with each other.
- the workpieces are brought into overlapping contact with each other. Then, a workpiece overlaps the other workpiece preferably marginally, so that virtually a workpiece at the edge of the upper workpiece and a workpiece forms the corresponding lower.
- the film is arranged on the surface of the workpieces and fixes the joint geometrically, so that the workpieces remain in their intended form during the joining process.
- the joint is fixed in the overlap area, ie on the surface of the workpieces, with the film. There is no film between the workpieces, as in the prior art, but only on the surface of the workpieces.
- this ensures a particularly simple fixation of the workpieces to be joined to one another.
- This measure has the particularly advantageous effect that a gap-free joining method can be used and, if appropriate, the film can also be removed again.
- the material of one of the two workpieces is no longer available as useful area for later applications.
- the workpieces are brought into abutment with each other in contact and formed there the joint (I-shock). Then the entire material of both workpieces is available as usable area for later applications.
- the joint formed between the workpieces is formed in the joint of the workpieces in contact with each other, so over the faces of the workpieces, z. B. sheets.
- the workpieces can be z. B. in the same plane to each other. Then they lie virtually flat next to each other and the film is arranged on the surface of the workpieces for geometrically fixing the joint.
- the workpieces can also be angled to each other, then they are z. B. at a right angle to each other.
- any pipe cross-sections can be made, for. B. square tubes, round tubes and so on.
- impact means that the surfaces to be joined of the workpiece (s) only come into contact with one another at their end faces. There are then no overlap of two or more workpieces. In this case, there are no lower or upper surface of a workpiece between at least two of the joined workpieces, but both workpieces to be joined are either flat in the same plane or angled towards each other. In this case, too, there is advantageously a gap-free joining method, since the film for fixing is present only on the surface of the workpieces, but not between the workpieces.
- Another embodiment relates to the formation of a tube. This is either in the overlap area or on impact from a single mechanically flexible workpiece, such. B. formed a metallic foil.
- the fixation of the joint with a film is therefore possible in various ways.
- film is advantageously saved as a fixing agent while maintaining the geometric shape of the joint.
- this measure has the advantageous effect of freeing up the choice of the joining method and of being able to use other joining methods in addition to laser beam welding methods.
- Some films are known to have insulating properties, e.g. B. Scotch tape ®. Then some joining methods may not be performed on the fixed areas of the joint, for. B. should there no electron beam welding can be applied.
- Adhesive film or adhesive film (transpaLaserstrahlsch spabacter the rent, insulating) entire joint, possibly the entire joint is fixed further joining methods, such.
- Adhesive film or adhesive film (transpa laser beam welding process on the rent, insulating) entire joint;
- the joint is only partially fixed electron beam welding, microplasma welding, arc welding, etc. at the non-fixed points of the joint
- Adhesive film or adhesive film (non-electron beam welding, microplas transparent, insulating) welding, arc welding to the entire joint is fixed to the entire joint
- Adhesive film or adhesion film (non-electron beam welding, microplas transparent, insulating) welding, arc welding to the joint is only partially fixed to the entire joint;
- non-transparent films according to the last two lines in the table are locally removed by the process heat of the joining process, for. B. by evaporation.
- the joint is fixed by means of a transparent adhesive film.
- a transparent adhesive film such as As Tesafilm
- Tesafilm the properties of a laser beam is not affected.
- the laser beam first penetrates the Tesafilm ® or other optically transparent films uninfluenced and joins the workpieces at the joint without gaps.
- the laser can be used particularly advantageously in combination with the adhesive film fixing since the optically clear, transparent film or the film is penetrated by the laser radiation without being influenced.
- Adhesive films require tensioning over the corner by redirecting the force. They are only loadable on train. Transparent films on the role as DeCeFix ® can also be used.
- Laser beam are to be added, were added by means of transparent adhesive film or adhesive film for processing by means of joining processes such as primarily laser beam welding, since the laser beam penetrates the optically transparent film and melts the workpieces.
- Non-transparent adhesive and adhesion films have also been used with electron beam and micro-plasma welding, possibly also with an arc welding process, in order to add workpieces according to the invention.
- laser beam welding methods can not be used.
- films were joined together as workpieces with the method according to the invention, in which a film is vaporized during the joining process before the jet or the arc or the plasma melts the workpieces underneath. This means that all films and joining methods can be freely combined with each other.
- a combination of laser beam welding is applied with a superficially with adhesive film or adhesive film fixed joint.
- the laser beam first passes through the transparent film and then hits the joint. Again, there is no film between the workpieces, so that a gap-free joining is made.
- metal-free and non-metallic films and sheets of 0.005 mm to 5 mm thickness have already been joined together without any gaps by the method according to the invention.
- the workpieces can have any thickness, that is, from 0.005, 0.006, 0.007, ... 4.997, 4.998, 4.999 to about 5 mm.
- the dimensions of the width and height of the sheets and films are not subject to any restrictions per se.
- the fixation and clamping problems customary in the prior art have been dispensed with in the case of large-area workpieces, so that positive-locking fixing can be provided for the first time as an alternative to conventional clamping technology.
- the method according to the invention can be used in particular in prototype construction with variable component geometries.
- the workpieces can also be arranged on substrates and fixed with film, in which the substrate transmits its shape to the workpieces.
- Workpieces produced by the method according to the invention consist in particular of a film in which the film is present in a gap-free manner with itself, e.g. B. thin tubes. These are z. B. usable as a scintillation tube.
- the workpieces according to the invention are, in particular, a small tube in which the ends of the film are overlapping or butt-jointed (I-butt).
- the length can z. B. between 10-50 mm with a diameter of 1- 10mm.
- the tubes according to the invention thus consist in particular of a thin-walled, in particular metallic, aluminum or beryllium foil which has a thickness of between 0.005 and 5 mm.
- the workpieces or the film can have any thickness of 0.005, 0.006, 0.007, ... 4.997, 4.998, 4.999 to about 5 mm and assume any intermediate value. With respect to the dimensions of the width and height of the sheets and foils, these in turn are not subject to any restrictions per se.
