Patentansprüche:Patent claims: 1. Verfahren zum. Punktschweißen von Werkstücken mit isolierenden Schichten oder Zwischenlagen; insbesondere von Transformatorenblechen, dadurch gekennzeichnet, daß die von den Elektroden berührten, zu verschweißenden Werkstücke an beliebiger Stelle leitend verbunden werden.1. Procedure for. Spot welding of workpieces with insulating layers or liners; in particular of transformer sheets, characterized in that that the workpieces to be welded touched by the electrodes are conductively connected at any point will. 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß mittels Zange, Klammer o. dgl. die zu verschweißenden Werkstücke festgeklemmt und von ihrer Isolation an der Klemmstelle befreit werden, so daß ein künstlicher Stromschluß herbeigeführt wird.2. The method according to claim 1, characterized in that by means of pliers, clamp or the like. The workpieces to be welded are clamped and their isolation be released at the terminal point, so that an artificial current circuit is brought about will. 3. Verfahren nach Anspruch I, dadurch gekennzeichnet, daß für die Schweißung der Stanzgrat der Werkstücke belassen wird, um die leitende Verbindung zwischen den von den Elektroden berührten Werkstücken herzustellen.3. The method according to claim I, characterized in that for the weld the punching burr of the workpieces is left to create the conductive connection between the workpieces touched by the electrodes to manufacture.
