A method for along -, - and diagonal defect testing by means of ultrasound workpieces according to the pulse - echo - the method

摘要

in the procedure for the longitudinal, transversal and schru00e4gfehlerpru00fcfung ultrasonic workpieces, a pru00fcfkopftru00e4ger (26), at least one probe (32 to 36) has on a surface of the workpiece translatorisch (44, 64) hinwegbewegt.ultrasonic pulses are generated in rapid succession by the probe (32 to 36) along each of the schallstrahls in pru00fcfbereichen on the surface of the workpiece (44, 64), and all of these pru00fcfbereiche on a linienhaften testing areso that in all pru00fcfbereiche interrupted translatorischer movement in one and the same range coincide, and with the sound ray in a predetermined, constant angle to each range was normal (38) lost. the sound ray are run on a kegelmantel to respective normal (38).a full circulation of 360 degrees is provided in a period which is shorter than the period of time, the translational movement needs to track with the dimensions of a pru00fcfbereichs to cross. a circulation at least ten ultrasonic pulses are generated and the surface of the workpiece (44, 64) are coupled.
