Multifunction UT - Phased Array Probe for NDE - Examinations
Author Werner Rathgeb
- Small dimensions
- Angles of incidence within 0° to 70° in steel
- Large bandwidth
- The possibility for using mode conversion and "Tandem" techniques.
- High sensitivity
- Sufficent signal to noise ratio
- Resistant against mechanical stress
The result of this development program was a Multifunction UT - Phased Array Probe
The features are:
- All points 1 to 7 are fullfilled
- High damped UT- probe based on "Composite" material
- 16 elements
- High sensitivity in the near surface area
- Stainless Steel - housing with flexible coax-cable and waterproofed connector
- Vertical scew range from 0° to 75° for long and shear waves.
Phased Array Probes
All probe characteristics like pulse, spectrum, soundfield and sensitivity are compareable to standard UT-Probes with a single function and exceed former PA - Probes.
After passing the qualification program in laboratory, the Multifunction UT - Phased Array Transducer was used in field in March 96 with great success. The very short time schedule
and a lot of geometrical restrictions were the backround conditions. The scanning areas could be optimized and the inspection volume was covered by 100%. The new technique was effective , time and money were saved.
Dipl.-Ing. Werner Rathgeb,
born 1948, studied Material Sience at the University of Berlin.
From 1976 until today be worked in several departments of SIEMENS/KWU.
Since 1996 he has been in charge of the department for probe development at SIEMENS/KWU in Erlangen, Germany.
