Abstract

Die Erfindung betrifft ein Verfahren zur Schweissstromsteuerung beim Widerstandsschweissen, insbesondere beim Punktschweissen, die durch ein allmaehliches Ansteigen des Schweissstroms gekennzeichnet ist. Das Ansteigen des Schweissstroms wird dann abgebrochen, wenn der Durchgang des Widerstandes an der Schweissnaht die Groesse seines lokalen Maximums erreicht oder sich diesem Maximum naehert, und dass das Schweissen dann bei der eingestellten Groesse des Schweissstroms fortgesetzt wird, der beim Abbrechen seines Ansteigens erreicht wurde.
