Using TOFD technique on autenitic materials

Do you have written information about using TOFD technique at crack detection on welds on autenitic materials?

.
Regarding inspection of austenitic material there are problems to be expected. The frequency of the ultrasonic sound is the key fact. Definitively the noise created by the material could be high. A possibility to reduce noise to determine the very low diffracted signals steaming from cracks etc. may be found in the application of a 12-bit analog to digital converter in combination with the carefully selected frequencies of the transducers which can be tuned optional.

We would be happy to discuss your application further by return e-mail.

Re: Using TOFD technique on autenitic materials
Could you send me more information of meaning of TOFD?
Is posible to make tank bottom analyzes without opening the tank?

Thanks
