Blog : What's new ? technical tip: to focus or not to focusCategory "NDT Consulting and Techniques" | No comment

Tech tip Ed Ginzel

Ed Ginzel, retired consultant with Materials Research Institute, active member of the community and CIVA user, explains in a technical tip  why a focused beam should not be used for general weld inspection.

His demonstration based on CIVA simulation can be downloaded here. It shows that the increase of sensitivity due to focusing is done at the expense of reducing sensitivity in the weld/HAZ zone, thereby requiring the operator to use more receiver gain in the TCG construction in the region of interest. As a result of the increased beam spread that occurs after the focal point, there is reduced beam resolution.  Therefore, closely spaced indications are more difficult to resolve.

In the framework of your NDT/NDE activity, you are working on a UT inspection with a procedure requiring the use of one or more probes with a separate Transmitter and Receiver (TRL probes). You would like to utilize the benefits of CIVA modeling software, but you’re not sure of some input parameters required in the CIVA Graphical User Interface for such probes, or you do not know which numerical values should be defined in order to accurately model your probes and get relevant simulations. Don’t worry, EXTENDE can provide you with a probe setting file ready to load in CIVA and based on experimental data. You just need to provide us with some data measured with the real probe as well as some basic information about it. We can definitely help you; do not hesitate to contact us for more information.
