Anordnung zur Ultraschalleinbringung bei der Ultraschallanalyse von Widerstandsschweissverbindungen

The description relates to an arrangement for feeding ultrasound in the analysis of spot-welding joints. The invention is characterized by the fact that the ultrasonic transmitter and if required the receiver are attached to the outer wall of the electrode shank or the electrode holder. This is permitted by the fact that no longitudinal waves are used for investigating the welding nugget by ultrasonic transmission
