Abstract
A method for the non-destructive ultrasonic testing of a part by the analysis of echoes returned by the part in response to the emission of an ultrasonic wave via an ultrasonic transducer, includes a step of determining a variable gain curve and a step of correcting the amplitude of the echoes returned by the part according to the variable gain curve and the moments of reception of the echoes. The method further includes steps of: producing a wave function representative of an ultrasonic transducer; producing transfer functions Frepresentative of the frequency responses of reference samples Rof the material forming the part; and calculating reference attenuation values between the wave function and the results of calculations of filtering of the wave function by the respective transfer functions Fof the reference samples R.
