Probe of ultrasonic test, ultrasonic test equipment, Test Procedure by ultrasound, and Method for Manufacturing seamless tubes or Pipes

摘要

The test procedure by Ultrasound according to the present includes the steps of providing a test probe Ultrasound 1 11 with a Plurality of Transducers with a tubular Object test pAnd to do that properly selected Transducers between the Plurality of Transducers transmit and receive Ultrasonic Waves so that the Ultrasonic Waves propagate in the tubular object of Trial in a Plurality of different directions of propagation.A condition in which sets of ultrasonic test so that the respective angles of refraction external QR of ultrasonic waves in a Plurality of directions of propagation are approximately equivalent and / or the respective angles of refraction Waves internal QK ULT Rasonicas in a Plurality of directions of propagation are approximately equivalent.
