Post Subject: Wave modes in Automated ultrasonic testing 8 channel module PV-100
Please provide me with the wave modes in UT -8channel module which is the combination of TOFD and pulse echo. Also i could not know the angles in the pulse echo modes. In TOFD i am using 60 degree and 70 degree wedges.

Normal practice with the PV-100 is to use 45 shear wave transducers in full skip for the cap, and 60 degree shear wave transducers for the root - one on each side. For very thick materials, you may want to use creeping waves for the cap. Your TOFD sounds correct; are you using both 60 and 70 degree shear waves for TOFD at the same time?

Yes. We are using both 60 degree and 70 degree shear wave for TOFD. for Pulse echo we are using two groups and the display of both the pulse echo groups shows the through thickness indications.

It sounds like you are doing "best practice" right now. If you need more help, Olympus NDT has a spreadsheet showing the recommended procedures for various wall thicknesses. Send me an e-mail if you want more information.
