Abstract

To bond together two metal components, they are welded together in a first step in a single stage spot welding action. In a second step, they are soldered together at the welded seam, using hard solder.

Description

Die nachfolgende Erfindung betrifft ein Verfahren zum Verbinden von zwei Metallteilen, welche in einem ersten Schritt miteinander verschweißt werden.The following invention relates to a method for Connect two metal parts, which in a first Step welded together.

Unter dem Begriff "Schweißen" wird ein Fügeverfahren der Fertigungstechnik verstanden, bei dem unter Einwirkung von Wärme, Kraft oder Kraft und Wärme eine stoffschlüssige Ver­ bindung zwischen Werkstoffen hergestellt wird. Das Schweißen kann mit oder ohne Zusatzwerkstoffe erfolgen, es wird durch Schweißhilfsstoffe, wie Schutzgase, Schweißpulver und -pasten ermöglicht oder erleichtert.The term "welding" is used for joining Manufacturing technology understood, under the influence of Warmth, strength or power and warmth a cohesive bond between materials. The welding can be done with or without filler materials, it will through welding aids, such as protective gases, welding powder enables and facilitates pastes.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, das Verbinden von zwei Metallteilen wesentlich zu verbessern.The present invention has for its object that Joining two metal parts to improve significantly.

Zur Lösung dieser Aufgabe führt, daß die Metallteile in einem zweiten Schritt im Bereich der Schweißnaht miteinan­ der verlötet werden. To solve this problem leads that the metal parts in a second step in the area of the weld who are soldered.  

Unter dem "Löten" wird ein Fügeverfahren zum Verbinden ver­ schiedener metallischer Werkstoffe mit Hilfe geschmolzener Zusatzmetalle (Lote) verstanden, deren Schmelztemperatur unterhalb derjenigen der Grundwerkstoffe liegt. Die Grund­ werkstoffe werden benetzt, ohne geschmolzen zu werden.Under the "soldering" is a joining process for connecting ver different metallic materials with the help of melted Additional metals (solders) understood their melting temperature is below that of the base materials. The reason materials are wetted without being melted.

Die wesentlichen Vorteile des vorliegenden Verfahrens sind zum einen, daß die Verbindung der beiden Metallteile abso­ lut dicht wird. Mögliche Haarrisse oder Schmelzdurchgänge, die beim Schweißen immer wieder entstehen können, werden durch das Lot aufgefüllt und abgedichtet.The main advantages of the present method are on the one hand that the connection of the two metal parts abso lut gets tight. Possible hairline cracks or melt runs, that can arise again and again during welding filled up and sealed by the solder.

Ein weiterer Vorteil ist, daß die Verbindung absolut rost­ sicher wird. Dies ist ebenfalls darauf zurückzuführen, daß Spalte und Hohlräume der Schweißnaht durch das Lot ausge­ füllt werden. Insbesondere wenn als Schweißverfahren das punktschweißverfahren angewandt wird, gilt dies.Another advantage is that the connection is absolutely rusty will be safe. This is also due to the fact that Gaps and voids in the weld seam are drawn out by the solder be filled. Especially when the welding process spot welding process is used, this applies.

Ferner wird die Verbindung fester und hochwertiger, es er­ gibt sich eine günstigere Krafteinleitung und ein günsti­ gerer Spannungsverlauf. An der Schweißnaht entsteht ein geringerer Einbrand, was wiederum weniger Nacharbeit erfor­ dert.Furthermore, the connection is firmer and higher quality, he said gives itself a cheaper introduction of force and a favorable lower voltage curve. At the weld seam a less penetration, which in turn requires less rework different.

Als Lötverfahren wird besonders das Hartlöten bevorzugt, bei welchem eine Arbeitstemperatur von über 450°C erreicht wird.Brazing is particularly preferred as the soldering method, at which a working temperature of over 450 ° C is reached becomes.
