Description
<Desc/Clms Page number 1>
Stahlelektrode für Lichtbogenschweissung.
Auf elektrischem Wege vorgenommene Schweissungen von Stahl haben gegenüber den autogenen
Schweissungen vor allem den Nachteil geringerer physikalischer Werte der Schweissstelle. Der Grund hiezu liegt in dem durch den Schweissprozess bedingten, ungünstigen Gefügeaufbau, der die Eigenschaften der Schweissstelle im Verein mit den häufig noch auftretenden Poren und Ungänzen nachteilig beeinflusst.
Da die elektrische Sehweissung wesentlich wirtschaftlicher als die autogene Schweissung ist, war man bestrebt, durch geeignete Zusammensetzung der Elektrode höhere physikalische Werte der Schweissstelle zu erzielen und die Güteeigensehaften der autogenen Sehweissung zu erreichen, bisher aber ohne Erfolg.
Es ist nun gelungen, eine Legierung für Elektroden zu finden, die die Herstellung einer hochwertigen Schweissung, welche selbst der autogenen Schweissung nicht mehr nachsteht, ermöglicht. Im Schweissmetall wird Titan im Ausmasse von etwa 0. 1-1.7% und gegebenenfalls Aluminium in Mengen von 0.1-1.5% beilgiert. Durch solche Legierungen wird eine überraschende Verbesserung der physikalischen Werte von Stahlschweissungen erzielt.
Derartige Elektroden haben mit den bekannten Gusseisenschweissstäben nichts gemeinsam, da bei diesen der Zusatz von Aluminium lediglich den Zweck hat, dass der Kohlenstoff im Roheisen in Form von Graphit ausgeschieden wird, um die Schweissstelle weich und bearbeitbar zu machen.
Durch die bedeutend grössere Wirtschaftlichkeit der elektrischen Schweissung gegenüber der Gasschmelzschweissung ist ein wesentlicher Vorteil gegeben.

Steel electrode for arc welding.
Electrically made welds of steel have compared to the autogenous
Welds mainly have the disadvantage of lower physical values of the welding point. The reason for this lies in the unfavorable structure of the structure caused by the welding process, which adversely affects the properties of the weld point in conjunction with the pores and discontinuities that still frequently occur.
Since electrical welding is much more economical than autogenous welding, efforts were made to achieve higher physical values of the welding point by means of a suitable composition of the electrode and to achieve the quality characteristics of autogenous welding, but so far without success.
We have now succeeded in finding an alloy for electrodes that enables the production of a high-quality weld that is no longer inferior to autogenous welding. In the weld metal, titanium is added in the amount of about 0.1-1.7% and, if necessary, aluminum in amounts of 0.1-1.5%. Such alloys result in a surprising improvement in the physical values of steel welds.
Such electrodes have nothing in common with the known cast iron welding rods, since the only purpose of the addition of aluminum is that the carbon in the pig iron is precipitated in the form of graphite in order to make the welding point soft and workable.
The significantly greater economic efficiency of electrical welding compared to gas fusion welding provides a significant advantage.
