Laboratory for Non-Destructive Testing
Ultrasonic Testing of Metals and Welded Joints (UT)
- The Sonatest VEO+ Ultrasonic Device is a state-of-the-art instrument for detecting volumetric defects in metal parts and welded joints. It is also used for crack detection, corrosion mapping, aerospace testing, and composite inspection.
- Testing is conducted using four methods:
- Conventional
- Phased Array
- TOFD
- FMC/TFM
- The laboratory has over 60 probes, enabling a wide range of testing capabilities.
Visual Testing (VT)
- Visual testing of metals and welded joints is applied as a basic non-destructive testing method and includes the detection of surface discontinuities and non-compliance of joint geometry with standard requirements.
- It is used both in the production phase and for checking the condition of welded joints on objects in operation.
- The laboratory has complete equipment for such types of testing.
liquid penetrant testing (PT)
- This method involves testing with colored and fluorescent penetrants. This method of testing detects surface discontinuities on metals, non-metals (plastics and ceramics) and on welded joints.
- The test is based on the detection of surface discontinuities larger than 10μm. The method is based on the capillary effect, i.e. the penetrant liquid penetrates the discontinuity and is then drawn to the surface by the developer.
magnetic particle testing (MT)
- This test method detects surface and subsurface discontinuities in ferromagnetic materials.
- The method is applicable for testing both base materials and welded joints.
- The laboratory has the most modern electromagnetic yoke, a white light source and an ultraviolet light source (UV lamp).
