Phased array and others for weld inspection

Dear Rolf Diederichs

the October issue of NDT.net had been dedicated to NDT for welding and there had been during the last two month indeed two events which should be cited here. The EPRI NDT Center organized a first Seminar about the application of phased array probes for ultrasonic inspection (Portland/Maine, 8.-9. September 1998). Some remarquable improvements for the ultrasonic weld inspection could be followed there, e.g. the use of realtime scanning angle beam probes for a fast and reliable weld inspection. Even a TOFD arrangement with phased array probes working as well in standard pulse echo as in TOFD mode had been discussed, but no information about results from a realized inspection are available so far. This idea is probably still in statu nascendi. It will certainly offer the most efficient ultrasonic tool for weld inspection. The Seminar demonstrated not only the potential benefits of this technique to solve former unsolvable problems and to carry out a more reliable, a faster and a better quantitative ultrasonic inspection but also it proved that ultrasonic phased arrays are nowadays no more an exotic playtool for academic institutes. Like for the medical applications Ultrasonic Phased Arrays will became one of the standard solutions offered to the industrial use of ultrasonic pulse echo techniques. The author of this letter presented at the seminar a contribution concerning the determination of the characteristic and essential parameters of phased array inspection systems, a question to be answered, if a more frequent use of the P.A technique is to be expected.
Another event was the First International Conference on NDE in Relation to Structural Integrity for nuclear and pressurized components ( Amsterdam, 20. - 22. October 1998), organized by the Joint European Research Center (Petten/Holland).
Beside an extensive discussion about the Qualification of NDT methods, the experience with several national systems and their critical evaluation, enough opportunity had been given to follow some interesting technical reports about modern NDT techniques for e.g. Eddy current, Ultrasound and X-Ray. Unfortunately the large number of contributions within the three conference days (with up to three parallel sessions) reduced the exchange of information to a more receptive attitude.
The specialist for NDT of welds could among others once again see an X-ray system with a Gamma-Camera and several applications of ultrasonic Phased Array Probes.
This short notice should apologize my fairly long silence.

With best regards

Hermann Wuestenberg

TOPAZ® 64: Fully Integrated Portable 64 Channel PAUT Instrument with FMC & TFM

Introducing TOPAZ64, the industry’s most intelligent fully integrated, portable 64-channel phased
...
array ultrasound (UT) instrument. TOPAZ64 combines code-compliant phased array UT with the industry’s most advanced full matrix capture (FMC) and total focusing method (TFM) capabilities. Featuring the highest acquisition frequency in its class, high resolution FMC and a 12” multi-touchscreen, users can easily visualize even the smallest flaws. TOPAZ64 can generate a bipolar pulse that provides more acoustic energy versus previous models for punching through thick components. The result is a portable tool that delivers increased inspection coverage, more accurate signals, and the ability to handle all UT inspections in one package. TOPAZ64 is ideal for challenging applications in transportation, oil and gas, manufacturing and power generation.
