Definitions
- the invention relates to a method for laser beam soldering of aluminum alloys using a suitable flux.
- Laser beam soldering is an alternative thermal joining process to e.g. B. components made of aluminum alloys or components made of aluminum and components made of other materials.
- the use of laser radiation is preferred when the components to be connected may only be partially exposed to heating.
- the required heat is focused by converting concentrated, high-energy radiation when it hits the workpiece.
- the absorbed portion of the laser radiation heats the workpiece to the soldering temperature and melts the solder so that it can wet the surfaces to be joined.
- the absorption of laser radiation is of central importance, since only the energy portion of the laser radiation is available for the joining process.
- the absorption rate can e.g. B. can be improved by suitable coating agents. This is how graphite improves the absorption rate of steel.
- the object of the present invention is to provide a method for laser beam soldering of aluminum alloys, in which laser energy-absorbing aids are to be used.
- the fluxes suitable for aluminum soldering are used as auxiliaries which absorb laser energy.
- the term "potassium fluoroaluminate” encompasses the known complex aluminum fluorides of potassium, which are composed of potassium, aluminum, fluorine and optionally water.
- Preferred fluxes are also cesium fluoroaluminate fluxes or mixtures of these fluxes with Al / Si, Al / Zn or Si powder.
- Active fluxes such as K 2 SiF 6 , KZnF or CsSiF are also suitable.
- Fluxes in the sense of the invention can, for. B. as potassium fluoroaluminate KAlF 4 , KA1F 5 , K 2 A1F 3 -H 2 0 or K 3 A1F 6 contain.
- the pentafluoroaluminate can also be in the form of irreversibly dehydrated products.
- the flux can be used as such, optionally with the use of customary auxiliaries.
- a binder can be provided as an auxiliary which improves the adhesion of the flux to the surface of the aluminum components to be connected.
- the flux is advantageously used in the form of a flux preparation which contains the flux as a slurry or paste in water, an organic liquid or a mixture of water and organic liquid.
- organic liquid alcohols are to be understood in particular methanol, ethanol, propan ⁇ l or isopropanol.
- K 2 SiF 6 and potassium fluoroaluminate mix individually or as a mixture with the liquid phase.
- the water or organic liquid content is adjusted so that the desired consistency with regard to the slurry or paste is achieved.
- the joints to be soldered can be coated in a conventional manner, e.g. B. by spraying, sprinkling, sprinkling, brushing.
- the coating of the metal surface with the laser energy absorbing aid is 3 to 50 g / m 2 .
- the auxiliary is a flux or mixture of fluxes
- the loading of the surface is expediently 10 to 20 g / m 2 . If a flux / metal powder mixture is used, the loading is advantageously 30 to 40 g / m 2 .
- the method is also suitable for joining solder-plated alloys.
- the laser beam soldering of aluminum with other metals such. B. steel, copper, iron, titanium, etc., is made possible by coating the joints with the tools mentioned.
- the soldering can be carried out with both continuous and pulsed laser radiation. Are suitable for. B. NdrYAG solid-state lasers or C0 2 lasers.
- the laser beam power directly determines the power density and the path energy.
- the soldering speed is directly dependent on the path energy.
- the process gas used and the respective amount of process gas influence the oxidation and / or, depending on the type of gas, the reduction of the soldering area in the interaction zone of the soldering process.
- a CO 2 laser with an output of 1.5 kW was used.
- Feed speed 50 to 70 mm / min.
