Description

Schweißdrähte oder -elektroden aus austenitischen Stählen zum Schweißen von austenitischen Manganstählen Zusatz zum Patent 3'46 130 Im Patent 7q.6170 ist die Verwendung von Schweißdrähten und -elektroden aus austenitischen Stählen mit bis 0,7% Kohlenstoff, mindestens 120/0 Mangan, Rest Eisen mit den üblichen Gehalten an Silizium und Verunreinigungen zum Verbindungs- und Dichtschweißen von austenitischen Manganstählen geschützt, wenn von der Schweißverbindung hohe Zähigkeit nach Luftvergütung gefordert wird, ohne daß der Schweiße sonstige Legierungselemente zugesetzt werden. Dabei bestehen die Drähte oder Elektroden vorzugsweise aus einem austenitischen Stahl, der o,25 bis 0,6% Kohlenstoff und 2o bis 13% Mangan enthält. Die Elektroden können blank verschweißt werden, und die fertige Schweiße braucht keine Vergütungsbehandlung zu erfahren.Austenitic steel welding wires or electrodes for welding of austenitic manganese steels Addition to patent 3'46 130 in patent 7q.6170 is the use of welding wires and electrodes made of austenitic steels with Up to 0.7% carbon, at least 120/0 manganese, the remainder iron with the usual contents of silicon and impurities for joint and sealing welding of austenitic Manganese steels protected if the welded joint has high toughness after air treatment is required without other alloying elements being added to the weld. The wires or electrodes are preferably made of an austenitic one Steel containing 0.25 to 0.6 percent carbon and 20 to 13 percent manganese. The electrodes can be welded blank, and the finished weld does not require any tempering treatment to experience.

Weitere Untersuchungen haben nun ergeben, daß es vorteilhaft ist, die Schweißung mit Drähten oder Elektroden aus austenitischen Stählen vorzunehmen, .die höchstens 0,7% Kohlenstoff, mindestens 12% Mangan und o,6 bis i,50/0 Silizium, Rest Eisen mit den üblichen Gehalten an Eisenbegleitelementen enthalten. Die durch diesen erhöhten Siliziumgehalt herbeigeführte Verbesserung wirkt sich insbesondere bei der Handschweißung aus. Bei Einhaltung des in austenitischen Manganstählen üblichen Siliziumgehaltes von etwa o,3$°/0 ist vor allem bei der Handschweißung das Schmelzbad noch sehr unruhig, und die Spritzverluste sind entsprechend verhältnismäßig hoch. Diese Nachteile und auch die Gasblasenbildung, die sonst zuweilen festgestellt werden konnte, treten nach der Erhöhung des Siliziumgehaltes auf wenigstens o,6%, vorzugsweise auf mehr als o,70/0 nicht mehr auf. Auch diese Elektroden können blank verschweißt werden, und es ist nicht notwendig, die fertige Schweiße einer Vergütungsbehandlung zu unterwerfen.Further investigations have now shown that it is advantageous welding with wires or electrodes made of austenitic steels, .the maximum 0.7% carbon, at least 12% manganese and 0.6 to 1.550 / 0 silicon, The remainder contains iron with the usual levels of accompanying iron elements. By improvement brought about by this increased silicon content works especially when welding by hand. If the in austenitic Manganese steels with the usual silicon content of around 0.3% are mainly used in manual welding the weld pool is still very restless and the spray losses are correspondingly proportionate high. These disadvantages and also the gas bubble formation that is otherwise sometimes noted could be, occur after increasing the silicon content to at least 0.6%, preferably to more than 0.70 / 0 no longer. These electrodes can also be bare be welded, and it is not necessary to heat-treat the finished weld to subjugate.

Im allgemeinen wird man mit dem Siliziumgehalt nicht über i 9/o hinauszugehen brauchen.In general, the silicon content will not go beyond i 9 / o to need.
