oder legierten anderen Metall. 5 Vorteilhafte Ausführungsarten der Erfindung, die Solche Verbindungen sind zur Herstellung dichter einzeln oder in Verbindung miteinander angewandt Durchführungen von Thermoelementen durch die werden können, bestehen darin, daß das andere Mate-Hüllen von zur Verwendung in einem Atomkern- rial eine Zirkonlegierung, beispielsweise eine unter der reaktor bestimmten Atomkernbrennstoffelementen Handelsbezeichnung Zirkaloy bekannte Zirkonlegienotwendig. Das Herstellen von gas-, dampf- und io rung, Nickel, eine Nickellegierung, beispielsweise eine flüssigkeitsdichten, gegenüber hohem Druck bei hoher unter der Handelsbezeichnung Inconel bekannte Temperatur beständigen Verbindungen zwischen Nickellegierung, oder rostfreier Stahl ist; das Schweikreiszylindrischen Bauteilen und von ihnen durch- ßen im Lichtbogen unter Neutralgasatmosphäre, insdrungenen Kesselwandungen durch Einschweißen der besondere Argon, durchgeführt wird; das andere zum kreiszyHndrischen Bauteile im Lichtbogen unter einer 15 Auftragen bestimmte Material ein Magnesium-Man-Schutzgasabdeckung ist bereits allgemein bekannt gandraht oder ein Magnesium-Zirkoniumdraht ist.
(deutsche Patentschrift 1142 977). Auch ist es bereits Die Erfindung wird nun an Hand eines Ausfühbekannt, dünnwandige Rohrstutzen in dickwandige rungsbeispiels in Verbindung mit der Zeichnung näher Behälter in der Weise einzuschweißen, daß das erläutert. In der Zeichnung ist die einzige Figur ein Schweißgut um den Rohrstutzen herum in eine im ao axialer Schnitt einer erfindungsgemäßen Verbindung, dickwandigen Behälter vorgesehene Ringnut mit Wie in der Figur gezeigt, soll ein Thermoelement 1 kegelförmigen Begrenzungsflächen eingefüllt wird durch einen Magnesiumkörper 2 dicht in das Innere (deutsche Patentschrift 690 630). Weiterhin sind aus eines geschlossenen Volumens geführt werden. Das der DIN-Norm 1912 eine Reihe von Schweißnähten Thermoelement 1 ist an einem Stück 3 angelötet, das bekannt, darunter auch eine Schweißnaht mit halb- 25 bei 12 durch Elektronenbeschuß auf einem Körper 4 rundem, breiterem Nahtgrund, die sogenannte J-Naht. aus rostfreiem Stahl, Zirkaloy, Inconel oder Nickel Alle diese Vorveröffentlichungen betreffen jedoch angeschweißt ist. Ein bei 6 am Stück 3 angelöteter offensichtlich nur das Schweißen von Stahl und Eisen Stopfen 5 ermöglicht die Vervollkommnung der Ab- oder anderen leicht miteinander zu verschweißenden dichtung zwischen dem Thermoelement 1 und dem Materialien. 30 Körper 4.The invention relates to a high temperature th, frustoconical connector section, gas-tight connection between a sleeve-shaped which are nested, and that the two work pieces made of pure or alloyed magnesium work pieces with a ring groove filling and a plug-like workpiece made of a pure support metal are welded to one another,
or alloyed other metal. 5 Advantageous embodiments of the invention, which can be used individually or in connection with one another for the production of more dense such connections, consist in that the other material sheaths of a zirconium alloy for use in an atomic core rial, for example one under the reactor-specific atomic nuclear fuel elements trade name zircaloy known zirconium alloy necessary. The production of gas, steam and ionization, nickel, a nickel alloy, for example a liquid-tight connections between nickel alloy, or stainless steel, which are resistant to high pressure at high temperature known under the trade name Inconel; the welded circle cylindrical components and through them penetrate in an arc under a neutral gas atmosphere, penetrated boiler walls by welding the special argon; the other material intended for circular-cylindrical components in the arc under a 15 application is a magnesium-man shielding gas cover, which is already well known, or is a magnesium-zirconium wire.
(German patent specification 1142 977). Also it is already The invention is now known by means of an embodiment, thin-walled pipe socket in thick-walled approximately example in conjunction with the drawing to weld closer container in such a way that this explains. In the drawing, the only figure is a weld metal around the pipe socket in an annular groove provided in the ao axial section of a connection according to the invention, thick-walled container.As shown in the figure, a thermocouple 1 is supposed to be filled with conical boundary surfaces through a magnesium body 2 tightly into the interior (German patent 690 630). Furthermore are to be guided from a closed volume. The DIN standard 1912 a number of welds thermocouple 1 is soldered to a piece 3, which is known, including a weld with a half-25 at 12 by electron bombardment on a body 4, round, wider seam base, the so-called J-seam. made of stainless steel, zircaloy, inconel or nickel. All these prior publications concern however welded on. A at 6 on the piece 3 soldered obviously only the welding of steel and iron plug 5 enables the completion of the seal or other easily welded seal between the thermocouple 1 and the materials. 30 body 4.
