Description
Gegenstand der Erfindung ist ein Verfahren zum elektrischen Widerstandsschweißen von Aluminium, insbesondere zum Punkt- und Nahtschweißen. Es ist bisher mittels Widerstandsschweißung nur möglich gewesen, Aluminium durch Stumpfschweißung zu verbinden. So sind Schweißmaschinen für dasThe invention relates to a method for electrical resistance welding of aluminum, especially for spot and Seam welding. So far it has only been possible to use resistance welding, aluminum to be connected by butt welding. So are welding machines for that
_ Stumpfschweißen von Aluminiumdrähten mit Erfolg in Verwendung. Dagegen ist besonders eine Punktschweißung bei Aluminium und aluminiumreichen Legierungen bisher mit Erfolg nicht durchführbar gewesen. Eine einzige bekannt gewordene Methode, welche gute Schweißungen ergibt, hat sich nicht eingeführt, weil sie für die Praxis zu umständlich war. Diese Arbeitsmethode bestand darin, daß man das zu verschweißende Aluminiumblech zwischen zwei dünne Eisenbleche legte, so daß der Stromübergang von der Punktelektrode_ Butt welding of aluminum wires with success in use. Against it is special spot welding of aluminum and aluminum-rich alloys with success so far not been feasible. A single known method that produces good welds has not been introduced, because it was too cumbersome for practice. This working method consisted in that you put the aluminum sheet to be welded between two thin iron sheets so that the current transfer from the point electrode
ao zum Aluminium und umgekehrt erst durch das Eisenblech passieren mußte. Diese Methode ergibt recht gute, gesunde Schweißungen, ist aber, wie schon gesagt, für den praktischen Gebrauch zu umständlich, weil man für jeden Punkt eine neue Eisenblechfläche braucht und sehr oft gar nicht imstande ist, die Eisenbleche zu verwenden.ao to the aluminum and vice versa first had to pass through the iron sheet. This method results in very good, healthy welds, but, as already said, is for practical use Too cumbersome to use because you need a new sheet iron surface for each point and very often is unable to use the iron sheets at all.
Nach dem neuen Verfahren wird nun wie folgt gearbeitet: Die zu vereinigenden Flächen werden mit einer dünnen Jodlösung bestrichen, oder es wird eine Auflösung von Jodsilber oder Kupferjodid in einer Jödlösung verwendet. Diese Arbeitsweise ergibt ohne alle besonderen Hilfsmittel bei verhältnismäßig kleinen Stromdichten gesunde und sehr zähe Schweißungen. Es geben auch wohl andere zum Schweißen von Aluminium bereits bekannte Halogene, wie z. B. Chlor- und Fluorverbindungen, noch brauchbare Resultate, jedoch neigen die Schweißungen mit diesen beiden Halogenen sehr zum Beschlagen nach der Schweißung, und die Schweißungen sind deshalb nach kurzer Zeit recht unsauber geworden. Dagegen bleiben besonders die Schweißungen mit Jod und Jodverbindungen trocken und sauber.The new procedure now works as follows: The surfaces to be united are smeared with a thin iodine solution, or there will be a dissolution of iodized silver or copper iodide is used in an iodine solution. This way of working results without any special Aid for relatively low current densities, healthy and very tough Welds. There are also other known ones for welding aluminum Halogens such as B. chlorine and fluorine compounds, still useful results, but the welds with these tend both halogens are very foggy after welding, and the welds are therefore became quite unclean after a short time. On the other hand, welds with iodine and iodine compounds in particular remain dry and clean.
Sinngemäß ist dieses Verfahren auf die Herstellung von Nahtschweißungen anzuwenden. Es ist auch hier nur nötig, die Schweißzonen vorher mit Jodlösung oder einer Auflösung von Verbindungen von Kupfer oder Silber mit Jod zu bestreichen.This process can be applied analogously to the production of seam welds. It is only necessary here, too, the welding zones to be coated beforehand with iodine solution or a dissolution of compounds of copper or silver with iodine.
Diese Arbeitsvorbereitung ist einfach, leicht durchführbar und billig. Sie ist nicht nur für Reinaluminium, sondern auch für aluminiumreiche Legierungen, wie Silumin u. dgl., vorzüglich geeignet.This work preparation is simple, easy to carry out and cheap. She's not just for Pure aluminum, but also excellent for alloys rich in aluminum, such as silumin and the like suitable.
