Description
Es ist bekannt, bei Schweißdrähten innerhalb der Umhüllung außer dem eigentlichen Schweißdraht noch einen dünnen Aluminiumdraht anzuordnen, um eine Sauerstoffaufnähme beim Schweißen zu verhindern. Man hat auch schon versucht, Aluminium als Legierungselement in Schweißdrähten zu verwenden. Es hat sich jedoch gezeigt, daß Schweißdrähte aus einer mit Aluminium legierten oder desoxydierten Stahllegierung für die Gasschmelzschweißung und insbesondere für die elektrische Lichtbogenschweißung ungeeignet sind, weil das im Schweißdraht vorhandene Aluminium das Auftreten von Tonerdeeinschlüssen in der Schweißnaht bewirkt und dadurch die Güte der Schweißnaht beeinträchtigt.It is known to have welding wires inside the sheath other than the actual one Welding wire still a thin aluminum wire to be arranged in order to absorb oxygen to prevent when welding. Attempts have also been made to use aluminum as an alloying element to be used in welding wires. It has been shown, however, that welding wires from one with aluminum alloyed or deoxidized steel alloy for gas fusion welding and in particular are unsuitable for electric arc welding because this is in the welding wire The presence of aluminum causes alumina inclusions to appear in the weld seam and thereby impair the quality of the weld seam.
Überraschenderweise weisen Schweißdrähte, die mit einem nach dem Diffusionsverfahren hergestellten Überzug aus Aluminium versehen sind, den angeführten Nachteil nicht auf, sondern ergeben gut desoxydierte Schweißnähte, die frei von Tonerdeeinschlüssen sind. Den Gegenstand der Eras findung bilden demgemäß solche legierten oder unlegierten Schweißdrähte, die mit einem nach dem Diffusionsverfahren aufgebrachten Aluminiumüberzeug versehen sind.Surprisingly, have welding wires that are made with a diffusion process produced coating of aluminum are provided, do not have the disadvantage mentioned, but result in well deoxidized Weld seams that are free of alumina inclusions. The subject of the Eras-fiction is accordingly alloyed ones or unalloyed welding wires, which are applied by a diffusion process Are provided with aluminum coating.
Diese Schweißdrähte weisen den weiteren Vorteil auf, daß sie beim Lichtbogenschweißen* die Bildung eines ruhigen Lichtbogens begünstigen. So wurden mit einem nichtumhüllten, mit einer AluminiumdifTusionsschicht versehenen Schweißdraht aus Manganhartstahl weit günstigere Ergebnisse in bezug auf ruhigen Lichtbogen und Dichte der Schweißnaht erzielt als mit einem umhüllten Schweißdraht gleicher Zusammensetzung, jedoch ohne Aluminiumüberzug. Die Herstellung des Aluminiumüberzuges nach dem bekannten Diffusionsverfahren erfolgt durch Erhitzen der Drähte in Aluminiumpulver. Außerdem können die Schweißdrähte nach der Erfindung insbesondere dann, wenn sie für die elektrische Lichtbogenschweißung ver- *5 wendet werden sollen, auch mit einer an sich ■bekannten Umhüllung versehen werden.These welding wires have the further advantage that they are used during arc welding * encourage the formation of a steady electric arc. So with an uncovered, Welding wire made of manganese steel with an aluminum diffusion layer Far more favorable results in terms of steady arc and density of the weld are achieved than with an encased one Welding wire of the same composition, but without an aluminum coating. The production the aluminum coating is carried out by the known diffusion process Heat the wires in aluminum powder. In addition, the welding wires can after of the invention especially when they are used for electric arc welding are to be used, also be provided with a cover known per se.
