2. dass das hinzugefügte Metall der Verbindung weich und leicht zu feilen oder in anderer Weise von Hand oder maschinell zu bearbeiten ist,
3. dass die einzelnen Stücke so miteinander verbunden werden können, dass die Grossenabmessungen des   ursprünglichen   ganzen Stückes genau gewahrt bleiben. 



   Es sei noch darauf hingewiesen, dass eine solche Verbindung nicht nur eine Ausbesserung wie ein aufgesetzer Flicken bildet, sondern dass das Gussstück nach der Ausbesserung dem Wesen nach dasselbe ist, was es vor Eintreten des Bruches war. Der Wert des mit dem neuen Verfahren erzielten Erfolges ist daran zu bemessen, dass man bisher zerbrochene   Gussstücke   nur durch aufgesetzte Stücke in ungenügender Weise ausbessern konnte, wenn man nicht überhaupt das zerbrochene Gussstück zerstückelte.

2. that the added metal of the joint is soft and easy to file or otherwise manipulate by hand or machine,
3. that the individual pieces can be connected to one another in such a way that the dimensions of the original whole piece are precisely preserved.



   It should also be pointed out that such a connection not only forms a repair like an attached patch, but that the casting after the repair is essentially the same as it was before the breakage occurred. The value of the success achieved with the new process can be measured by the fact that previously broken castings could only be repaired in an inadequate manner by adding pieces if the broken casting was not dismembered at all.

Claims

PATENT CLAIM: Process for joining cast iron pieces by melting cast iron onto the heated and cleaned surfaces to be joined, characterized in that the parts to be joined are firmly clamped in the correct position to one another, the parts adjacent to the surfaces to be joined to a dark red heat and then the former itself directly heated by means of a non-oxidizing gas until they melt to form a part and then molten cast iron is added in small quantities, which unites with the partially molten surfaces of the parts to be connected without a loss of carbon content of the cast iron occurring.
