Description
Verfahren zum Punktschweißen von Metallen Die elektrische Punktschweißung von. Metallen, insbesondere von. Stahlblechen aneinander, läßt sich, nach den bekannten: Verfahren nur durchführen, wenn die zu vereinigenden Stücke in blankem Zustand vorliegen, insbesondere keinen Anstrich aufweisen. Derartige Anstrichfilme wirken; mehr oder weniger als Isolierschichten, die den Stromdurchgang durch, die zu verbindenden Stücke in hohem Maße beeinträchtigt, so daß eine ausreichende Verheftung der Stücke nicht erreicht werden kann. Wenn, auch die Außenseiten. der in blankem Zustand ane@inand:ergeschweißten Stücke nachträglich noch mit einem. Anstrich, etwa einem Rostschutzanstrich, versehen werden 'können, so entfällt doch diese Möglichkeit an. den durch, die Punktschweißung miteinander verhefteten. Flächen, die somit leicht korrodieren., wodurch auch die einzelnen Schweißstellen angegriffen werden.. Die Erfindung betrifft ein neues Verfahren zum elektrischen Punktschweißen von Metallen, das die Möglichkeit gibt, auch mit einem Anstrich, insbesondere einem Rostschutzanstrich, versehene Metalle einwandfrei miteinander zu verbinden" so daß also, insbesondere eine Rolstbildung auf den nach dem Aufeinanderschweißen unzugänglichen Seiten der Teilstücke mit Sicherheit vermieden werden kann,.Process for spot welding metals. Electric spot welding from. Metals, especially of. Steel sheets together, can be, according to the well-known: Only carry out the process if the pieces to be combined are in a bare state, in particular have no paint. Such paint films work; more or less than insulating layers that allow current to pass through those to be connected Pieces impaired to a great extent, so that sufficient stapling of the pieces cannot be achieved. If so, also the outsides. the one in the bare condition ane @ inand: welded Pieces with a later. Paint, for example a rust protection paint can be ', this possibility does not apply. the through, the spot weld pinned together. Surfaces that are therefore easily corroded. As a result, the individual welds are attacked .. The invention relates to a new method for electrical spot welding of metals, which gives the option of using a coat of paint, in particular a rust protection coat, works perfectly to connect "so that so, in particular a Rolstbildung on the after the welding inaccessible sides of the sections avoided with security can be,.
Das neue Verfahren zum; elektrischen Punktschweißen vorn Metallen, insbesondere Stahlblechen, besteht darin, d-aß die zu vereinigenden. Stücke vor dem Verschweißen mit einem Metallpulver enthaltenden Überzug versehen werden. Der Überzug besteht aus einem styrolisierten Öllack, dem ein präpariertes Aluminiumpulver zugesetzt ist. Das Pulver wird vorteilhaft vor dem Vermischen mit dem Bindemittel in einem fettlösenden Lösungsmittel angeteigt und/oder erhitzt, um die dem Aluminiumpulver etwa anhaftenden Fettspuren, zu entfernen. Es wird hierdurr' !, gleich-zeitig erreicht, daß das. Luftpolster, welch --s bei üblichen Metallpulvern die einzelnen Tei',@hen gegeneinander isoliert, verschwindet.The new method for; electrical spot welding of metals, especially steel sheets, consists in d-aß the to be united. Pieces before be provided with a coating containing metal powder after welding. Of the The coating consists of a styrenated oil varnish to which a prepared aluminum powder is added. The powder is advantageous prior to mixing with the binder in a fat dissolving solvent dough and / or heated, to remove any traces of grease that may have stuck to the aluminum powder. It will be here !, at the same time achieved that the air cushion, which --s with common metal powders the individual parts, isolated from one another, disappear.
