    摘要： In a method and a device for the ultrasonic monitoring of overlapping welded joints between a first sheet and a second sheet pulses are irradiated at an angle of between 15 and 80° into the first sheet by a first rotating probe head. The rotating probe head is arranged on a mount and has a tire rotating about the axle, coupled to the ultrasound transmitter and rolling along the first sheet, parallel to the overlapping welded joint. On ultrasound investigation of the overlapping welded joint the impulses transmitted to the second sheet are received by a second receiving rotating probe head, of similar construction to the first rotating probe head.

    摘要： A method for non-destructive testing of a weld joint of a bolt welded onto a contact area on a planar sheet metal using the lift ignition method uses directed ultrasonic signals. During the welding operation a weld pool having a modified material structure is formed beneath the contact area in the sheet metal. Ultrasonic signals are transmitted into the sheet metal using a directed and obliquely transmitting ultrasonic transmitter positioned at a coupling-in point A. An ultrasonic receiver is positioned at a coupling-out point B and receives the ultrasonic signals transmitted through the sheet metal at the coupling-out point B, an acoustic path being formed between the coupling-in point A and the coupling-out point B. The acoustic path is positioned so that it passes a center of the contact area in a distance d from this center, d being smaller than the radius of an intact weld pool and bigger than the radius of a non-intact weld pool, and the intensity of the ultrasonic signals transmitted along the acoustic path from the coupling-in point A to the coupling-out point B is detected.
