Interview - Jiang Yunxi

16th November 2015


Mr. Jiang Yunxi, from Matrix NDT, is the exclusive distributor of CIVA software in China. He accepted to answer some of our question about the NDT market in China and his activities.


Jiang Yunxi



Can you let us know how the NDT market is in China?

MatrixNDT is a company that supports ONE STOP Service on the Chinese NDT market. We share the high level inspection services here in China, including production, technology and goods, and we hope to be leaders in the improvement of NDT. We have all kinds of production, including simulation software and inspection equipment and systems. We joined a committee to compile two NDT standards, and we are members of the Professional Committee of Nondestructive Testing for the PetroChina Engineering Construction Association, as well as the Chinese society of NDT.

Regarding the NDT market in China, I think it is similar to other places in the world. We mostly use conventional technology, but it is our mission to generalize the use of new technology to solve new problems coming from new materials.


What are the main sectors using NDT in China?

Many industries need NDT methods, such as in lifting equipment, heavy equipment, power plants, electricity, railway, aerospace, etc. But the main sectors using the newest NDT methods are the vessel and heavy industries, the aerospace industry, and the nuclear industry.


Which technology is the most required there?

The main technology is still conventional X-Ray, UT, PT and MT, but we hope to show the advantages of new methods. Some new methods are powerful, green, and data is easy to save, which meets the requirements of the social progress.


Do you personally use CIVA?

Yes, my company and me always use CIVA for demonstrations. We have three licenses, and also published some papers regarding CIVA software to show its advantages.


Have you tried the new analysis module? What is your feedback on this new tool?

Yes, but I am still getting used to it. The new functions are useful and powerful, but some functions are not easy to find, such as the “modes identification” tool. It is not as convenient as it was in CIVA 11.


Do you think that the improvements of the new version fit with the needs of the market?

Yes, of course. And I hope the improvements can be continuous.


What would you recommend for the next CIVA versions?

In the next version, I hope you can add the following functionalities to their respective modules:

UT Module:

  • In the scanning panel, we hope for the addition of an ”imported trajectory” function for the 3D pieces;
  • Add surface waves in the simulations;
  • In the TOFD simulations, we hope for GTD models to be used to calculate the effect of side drilled holes, because as in the TOFD inspections, we always use side drilled holes as calibration defects.

ET Module: We hope 3D pieces can be imported.

RT Module: We hope to be able to simulate X-Ray sources with higher energies than 450KV than with the current version.
