Beschreibung
Zusammenfassung:	The invention relates to a device and method for determining parameters of a welding system. According to the invention, a welding area ( 18, 21, 22 ) is subjected to the action of ultrasonic waves, preferably to the action of shear waves, by using an ultrasound source ( 14 ). During a first welding process (n 1 ), a signal processing ( 30 ) determines a first ultrasonic permeability (Dn 1 ) from a received ultrasonic signal (UE). During at least one subsequent welding process (n 2 ), a second ultrasonic permeability (Dn 2 ) is determined from an ultrasonic signal (UE) that is received during a renewed exposure of the welding area ( 18, 21, 22 ) to ultrasonic waves. A display ( 32 ) and/or a diagnostic function and/or a correction of control quantities of the welding system is/are carried out as a function of the at least two ultrasonic permeabilities (Dn 1 , Dn 2 ).
