摘要： The invention relates to a method for determining the threshold value of screens which enable an evaluation of a sound coupling during the ultrasound testing of a series of spot welding joints of a selected type. Initially, a geometrical minimal thickness dMin is established for the spot welding joints. At least one echo of the front surface (entrance echo) is received in addition to one echo of the first reflection on a rear wall of the spot welding joint (first rear wall echo) and at least one further (n-th) rear wall echo. The propagation time tMin of the ultra sound pulse is defined for the path to the front surface to the rear wall and back to the front surface at a minimal thickness dMin and a propagation time tT for the total thickness. A first screen (B1) is set for the signal of the rear wall echo, starting at a moment in time t1S=tE+tMin−tSA and ending at a moment in time t1T=tE+tT+tSE, whereby tSA and tSE are additional small security measures. An n-th screen is correspondingly determined for the n-th rear wall echo. The testing head is oriented differently.

摘要： The invention relates to an ultrasound control device for non-destructively inspecting a workpiece. The inventive ultrasound control device comprises a transmitting-receiving sensor provided with an element for connecting to the input surface of a controlled workpiece, a transmitter which is connected to the sensor and sends pulses produced thereby to said sensor, a receiver connected to the sensor and a screen which is connected to the receiver for displaying electric echo signals received by the receiver. The sensor transmits ultrasound pulses which, on one hand are reflected by the input surface and return to said sensor, and penetrate into the workpiece and are reflected at least once by the back wall thereof, on the other hand. Said ultrasound control device also comprises a bar display for visualising the received electric echo signals. At least one signal value displayed on said display in a real time results from one of electric echo signals reflected by the input surface: an input echo reflected by the input surface, at least one echo from the back wall and/or one signal calculated on the basis of several echoes reflected thereby.
