Description

Aufschweißdrähte und -elektröden aus einer stellitartigen Legierung Stellitartige Legierungen für Aufschweißelektroden sind seit längerer Zeit bekannt. Während sie zunächst meist Wolfram, Kobalt oder beide Elemente in größeren Mengen enthielten, ist man später zur Einsparung dieser Wolfram- und Kobaltgehalte im wesentlichen zu Legierungen der Eisen-Chrom- oder der Eisen-Chrom-Mangan-Grtindlage übergegangen.Weld-on wires and electrodes made from a stellite-like alloy Stellite-like alloys for weld-on electrodes have been known for a long time. While initially they mostly contain tungsten, cobalt or both elements in larger quantities contained, one is later to save these tungsten and cobalt contents essentially switched to alloys of the iron-chromium or iron-chromium-manganese base.

Alle diese Aufschweißlegierungen sind jedoch unverformbar und daher nur als gegossene Elektroden bekannt. Dünne Abmessungen, z. B. a- bis 3-mm-Stäbe, können als solche nicht gegossen werden, sondern müßten auf völlig unwirtschaftliche Weise von stärkeren Abmessungen heruntergeschliffen werden.However, all of these weld-on alloys are non-deformable and therefore known only as cast electrodes. Thin dimensions, e.g. B. a to 3 mm rods, cannot be cast as such, but would have to be completely uneconomical Way to be ground down from thicker dimensions.

Das Verfahren gemäß der Erfindung geht zur Herstellung vonAufschweißdrähten und -elektroden dieser Art, bei denen der Werkstoff bei der gewünschten Zusammensetzung stellitartig, d. h. praktisch nicht oder, insbesondere beim Ziehen von Drähten, nur schwer verformbar ist, von einer Legierung aus, welche die verlangten Legierungselemente bereits enthält, jedoch, da sie bei Anwesenheit des verlangten Kohlenstoffgehaltes praktisch nicht oder nur schwer verformibar wäre, kohlenstoffarm oder kohlenstofffrei ist. Eine solche Legierung, z. B. eine Eisenlegierung mit 18 bis 32% Chrom, wird zunächst zu Drähten oder Elektroden verformt und darauf mit Kohlenstoff angereichert. Beispiel Eine Legierung, die mit 1,8% Kohlenstoff, o,8o% Mangan, 0,35% Silizium und 28%. Chrom praktisch unverformbar wäre, läßt sich mit niedrigem Kohlenstoffgehalt ohne Schwierigkeit zu Drähten verformen und auf i,8% Kohlenstoff. aufkohlen. Das trifft auch zu, wenn sie 2 bis 8% Wolfram, i bis, 40/a Silizium und 6bis,40%Kobalt, einzeln oder gemischt, enthält.The method according to the invention is for the manufacture of welding wires and electrodes of this type, in which the material in the desired composition stellit-like, d. H. practically not or, especially when pulling wires, is difficult to deform from an alloy which has the required alloying elements already contains, however, because it is present in the presence of the required carbon content would be practically impossible or difficult to deform, low-carbon or carbon-free is. Such an alloy z. B. an iron alloy with 18 to 32% chromium, is first formed into wires or electrodes and then coated with carbon enriched. Example An alloy containing 1.8% carbon, 0.8% manganese, 0.35% Silicon and 28%. Chromium would be practically non-deformable, can be with a low carbon content deform into wires without difficulty and on 1.8% carbon. carburize. That also applies if they contain 2 to 8% tungsten, i bis, 40 / a silicon and 6 bis, 40% cobalt, individually or mixed, contains.

Mit dem Verfahren gemäß der Erfindung ist es also möglich, an Stelle der nicht verformbaren oder nur mit zu hohem Aufwand verformbaren Legierungen solche mit günstiger Verformbarkeit zu verwenden und sie aus gießtechnisch vorteilhafteren Abmessungen herzustellen. Es ist insbesondere auch möglich geworden, dünne und dünnste Albmessungen, wie sie in der Technik bei Aufschweißdrähten und -elektroden in steigendem Maße gebraucht werden, auf wirtschaftliche Weise herzustellen.With the method according to the invention it is thus possible in place the alloys that are not deformable or that can only be deformed with too much effort are those to use with favorable deformability and they are more advantageous in terms of casting Manufacture dimensions. In particular, it has also become possible to be thin and thinnest Alb measurements, as they are increasing in technology for welding wires and electrodes Dimensions are needed to manufacture in an economical manner.
