Zusatz zum Patent 399946.Addition to patent 399946.

Patentiert im Deutschen Reiche vom 14. Dezember 1922 ab. Längste Dauer: 29. Juni 1940.Patented in the German Empire on December 14, 1922. Longest duration: June 29, 1940.

In dem Hauptpatent ist ein Verfahren zum Aufschweißen von Plättchen aus hochwertigem Stahl (Werkzeugstahl, Schneüdrehstahl usw.) auf minderwertigeren Stahl oder Eisen angegeben, bei dem die Schweißung nach dem elektrischen Widerstandsschweißverfahren vorgenommen wird. Für derartige Schweißungen eignet sich vorteilhaft eine besondere Abart des Widerstandsschweißverfahrens, nämlich das sogenannte Abschmelz- oder Abbrennverfahren, bei dem die zu schweißenden Gegenstände zunächst bis zur Berührung einander genähert und dann auf eine kurze Entfernung wieder voneinander entfernt werden, so daß zwischen den beiden zu verschweißenden Gegenständen ein oder mehrere kleine Lichtbogen entstehen. Durch diese werden etwa zwischen den zu verschweißenden Flächen vorhandene Unreinlichkeiten weggebracht und die Schweißflächen selbst sehr schnell auf die erforderliche Schweißhitze gebracht. Dies ist besonders vorteilhaft für das aus hochwertigem Material bestehende Stahlp-ättchen. da bei diesem die Schweißhitze sich nur auf eine verhältnismäßig dünne Schicht ausdehnen darf, um das Plättchen nicht zu überhitzen oder gar zu verbrennen. Hierbei sind die Einspannbacken für die Schweißgegenstände in der in. dem Hauptpatent angegebenen Weise zu wählen und anzuordnen.In the main patent is a method for welding on platelets made of high quality Steel (tool steel, cutting tool steel, etc.) specified on inferior steel or iron, in which the welding is carried out according to the electrical resistance welding process will. A special variant of the resistance welding process, namely the so-called melting or burn-off process, in which the objects to be welded are first brought closer to each other until they touch and then moved a short distance away from each other, so that one or more small arcs between the two objects to be welded develop. This removes any impurities that may exist between the surfaces to be welded and the welding surfaces themselves are brought to the required welding heat very quickly. this is particularly advantageous for the steel plate made of high quality material. because in this case the welding heat only extends to a relatively thin layer in order not to overheat or burn the plate. Here are the clamping jaws for the welding objects in the manner specified in the main patent to choose and arrange.
