Can TOFD replace conventional UT on welding?

Posted by: Rolf Diederichs , E-mail: rd@ultrasonic.de, on May 20, 1997 at 16:55:43:

Many advantages of the TOFD (Time of Flight Diffraction) method
are reported in literature.
Since the method works fast it can be an economically alternative to pulse echo UT or X-ray.
What are the draw backs especially for welding testing?
Is the method just a useful addition?
Is there already a standard established?
