Verfahren zur Herstellung von SchweißelektrodenProcess for the production of welding electrodes

Zusatz^ zum Patent 488815Addition ^ to patent 488815

Patentiert im Deutschen Reiche vom 25. Mai 1928 ab Das Hauptpatent hat angefangen am 5. November 1927.Patented in the German Empire from May 25, 1928 The main patent started on November 5, 1927.

Das Hauptpatent betrifft ein Verfahren zur Herstellung· van Schweißelektroden mit Zusätzen in Farm eines Dochtes. Die Füllmasse wird in ein Rohr fest eingestampft und dieses ,gefüllte Rohr zentral in die Kokille eingesetzt, wo,rauf das Schweißmetall beliebiger Legierung herumgiegossen wird. Der so hergestellte Block wird nun auf die gewünschte Elektrodenstäfke ausgewalzt.
to Bei Durchführung dieses Verfahrens zeigt es sich, daß beim Verwalzen der Blöcke insofern Schwierigkeiten auftreten, als das Füllungsmaterial ausgequetscht werden kann, wenn sein Schmelzpunkt unter der Walzig temperatur des herumgegossenen Elektroden-The main patent relates to a process for the production of welding electrodes with additives in the form of a wick. The filling compound is firmly tamped into a tube and this filled tube is placed centrally in the mold, where the weld metal of any alloy is poured onto it. The block produced in this way is then rolled out onto the desired electrode thickness.
When carrying out this process, it has been found that difficulties arise when rolling the blocks insofar as the filling material can be squeezed out if its melting point is below the rolling temperature of the electrode poured around it.

materials liegt. Es hat sich in der Herstellung als günstiger erwiesen, die Zusätze derart zu wählen, daß ihr Schmelzpunkt über der "Walztemperatur liegtj wodurch ein Ausquetschen oder Verformen des Dochtes ver- 20 mieden wird.materials lies. The additives have proven to be cheaper to manufacture to be chosen in such a way that their melting point is above the "rolling temperature" thereby causing squeezing or deformation of the wick is avoided.
