Abstract

A welding consumable comprises an antimagnetic high strength iron-manganese-chromium welding alloy or a self-fluxing nickel-chromium hard facing alloy of specified compositions. A novel welding consumable comprises an antimagnetic high strength iron alloy containing (by wt.) 20% Mn, 15% Cr, 0.3% Mo, 0.4% N and 0.03% C. An Independent claim is also included for a welding consumable for producing hard, wear resistant, self-fluxing nickel base hard facings, containing 25-40 wt.% Cr and optionally Mo to achieve a non-magnetic coating.

Description

Die Erfindung betrifft einen Schweißwerkstoff nach den Oberbegriffen des Patentanspruches 1 und dessen Verwendung. Ein Grundwerkstoff für Bohrgestänge an Erdbohrern für den untertägigen Bergbau oder die Erdölindustrie der Werkstoff­ bezeichnung P 550 weist die folgenden Eigenschaften auf:
The invention relates to a welding material according to the preambles of claim 1 and its use. A basic material for drill rods on earth drills for underground mining or the oil industry with the material designation P 550 has the following properties:

  • - chemische Zusammensetzung (in Gew.-%):
    - chemical composition (in% by weight):
  • - mechanische Gütewerte:
    - mechanical quality values:

Auch in der Schiffbauindustrie - etwa beim U-Bootbau - sind Grundwerkstoffe im Einsatz, welche eine hohe Festig­ keit, verbunden mit antimagnetischen und korrosionsbestän­ digen Eigenschaften, haben und zu verschweißen sind.Also in the shipbuilding industry - e.g. submarine construction - are base materials in use which have a high strength ability combined with anti-magnetic and corrosion-resistant properties, and have to be welded.

Auf dem Markt sind Schweißzusatzwerkstoffe bekannt, die entsprechend dem Grundwerkstoff gleiche oder ähnliche Fe­ stigkeitseigenschaften aufweisen; diese besitzen jedoch keine antimagnetischen Eigenschaften. Andererseits errei­ chen antimagnetische Schweißzusätze nicht die geforderten Festigkeitswerte.Welding consumables are known on the market that the same or similar Fe depending on the base material have strength properties; however, these have no anti-magnetic properties. On the other hand antimagnetic welding consumables do not meet the required requirements Strength values.

Entsprechende Probleme entstehen bei nichtmagnetischen Beschichtungen zum Verschleißschutz von nichtmagnetischen Stählen. Auch der diesbezügliche Grundwerkstoff entspricht beispielsweise jenem Werkstoff "P 550".Corresponding problems arise with non-magnetic Coatings for wear protection of non-magnetic  Steels. The relevant basic material also corresponds for example that material "P 550".

In Kenntnis dieses Standes der Technik hat sich der Erfin­ der das Ziel gesetzt, eine antimagnetische Schweißgutzusam­ mensetzung mit hohen Festigkeitseigenschaften als Panzerung anzubieten, die beispielsweise an den beschriebenen Bohrgestängen eingesetzt zu werden vermag oder als Verschleißschutz auf Grundwerkstoffen der erwähnten Art.The Erfin has knowledge of this state of the art who set the goal of an antimagnetic weld metal together Composition with high strength properties as armor to offer, for example, to the described Drill pipe can be used or as Wear protection on base materials of the type mentioned.

Zur Lösung dieser Aufgabe führt die Lehre des Patentan­ spruches 1; die Unteransprüche geben günstige Weiter­ bildungen an. Zudem fallen in den Rahmen der Erfindung alle Kombinationen aus zumindest zwei der in der Beschreibung, der Zeichnung und/oder den Ansprüchen offenbarten Merkmale.The teaching of the Patentan leads to the solution of this task saying 1; the subclaims give favorable further education. In addition, all fall within the scope of the invention Combinations of at least two of those in the description, the drawing and / or the features disclosed.

Erfindungsgemäß enthält ein Schweißwerkstoff zum Herstellen von harten - bevorzugt selbstfließenden - Ni-Basis-Panze­ rungen für eine nichtmagnetische Beschichtung als Ver­ schleißschutz mit einem Chromgehalt von etwa 25 bis 40 Gew.-%. Ein solcher Schweißwerkstoff kann stattdessen auch einen Gehalt an Cr und Mo von 25 bis 40 Gew.-% aufweisen. Zudem mögen Metalloide wie B, Si und C zur Absenkung des Schmelzpunktbereiches sowie zur Erhöhung des Verschleißwiderstandes zugesetzt werden.According to the invention contains a welding material for manufacturing of hard - preferably self-flowing - Ni-based patches for a non-magnetic coating as Ver wear protection with a chromium content of about 25 to 40% by weight. Such a welding material can also be used instead have a Cr and Mo content of 25 to 40% by weight. Metalloids such as B, Si and C may also be used to lower the Melting point range and to increase the Wear resistance can be added.

Der Anwendungsbereich dieses Schweißwerkstoffes soll sich auf den Schutz von nichtmagnetischen Bohrgestängen bzw. Stabilisatoren bzw. Instrumentengehäusen im Bereich der Bohrköpfe erstrecken. Zur Bohrkopforientierungsmessung muss - z. B. bei gezielten Bohrungen zu verschiedenen Lager­ stättenabschnitten von einem Standort aus - dieser Bereich unmagnetisch sein, um das als Messorientierung genutzte na­ türliche Erdmagnetfeld nicht zu stören. Nichtmagentische Eigenschaften - bzw. magnetische Eigenschaften ähnlich der Atmosphäre - werden im Bohrkopfbereich benötigt, um das örtliche Erdmagnetfeld nicht zu stören; an diesem orientieren sich nämlich die im Bohrkopfbereich eingebauten Messsonden. Diese Messorientierung wird vor allem bei Bohrungen benötigt, die nicht direkt über den kürzesten - geraden - Weg vorgetrieben werden, sondern über beliebige Umwege bzw. Kurven.The area of application of this welding material is said to be on the protection of non-magnetic drill pipes or Stabilizers or instrument housings in the area of Extend boring heads. To measure the drill head orientation - e.g. B. with targeted drilling to different camps Sections of sites from one location - this area be non-magnetic in order to use the na Do not disturb natural earth magnetic field. Non-magnetic tables Properties - or magnetic properties similar to that Atmosphere - are needed in the drill head area to do not disturb local earth's magnetic field; at this orient the built in the drill head area  Measuring probes. This measurement orientation is mainly used for Holes that are not directly over the shortest - straight - be driven forward, but over any Detours or curves.
