We offer non-destructive testing (NDT) services for metal structural components and industrial equipment to detect any potential defects.
This testing is conducted using technologies that do not interfere with the structure, ensuring that the surfaces remain unchanged and intact.
Non-destructive testing can be performed during the operational phase of machinery, equipment, and electronic components, as well as at the manufacturing stage.
We perform the following tests:
| No. | Type of Test | Code |
|---|---|---|
| 1. | Visual Testing | VT |
| 2. | Magnetic Testing | MT |
| 3. | Penetrant Testing | PT |
| 4. | Ultrasonic Testing | UT |
Visual Testing (VT) is the quickest and most cost-effective method of non-destructive testing. The inspection involves a thorough external examination of the object and precise measurements. While the test is relatively simple, it is also highly effective. It can be performed directly without the use of any tools or with the assistance of a magnifying glass, mirrors, an endoscope, or a videoscope.
The visual method is used primarily in assessing the discrepancies in welded joints and all types of welds at the stage of manufacturing a given structure, object, machine, etc.
Magnetic particle testing (MT) is used in cases where the tested material has undergone a change in shape. This method is used to test ferromagnetic materials (those that exhibit magnetic behavior). It allows for the detection of magnetic field dispersion caused by material cracks. MT testing eliminates damage that would not be noticed during visual testing.
MT non-destructive testing is used in aviation, automotive and foundry industries, among others. It also enables measurements of the hardness or thickness of materials.
Penetrant Testing (PT) allows the detection of any material discontinuities. This method utilizes the capillary action phenomenon and involves the penetration of a low surface tension liquid into narrow vessels known as capillaries. Any potential damage is then detected using light, most often white or ultraviolet, but also through dye techniques. However, penetrant testing is not suitable for porous surfaces or those with irregular shapes.
Penetrant Testing (PT) is used to detect leaks in welded joints and narrow-gap material discontinuities.
Ultrasonic Testing (UT) allows the detection of defects or leaks and provides an assessment of damage within the entire volume of the tested object, not just on the surface (as in VT and MT methods), but also internally. The method uses the propagation of ultrasonic waves. A special device records these waves, and after the data is saved, it is analyzed by a computer.
The UT method is widely applied in industries such as metallurgy, aerospace, railway mechanics, and energy. Ultrasonic testing is most often performed alternately with radiographic testing, as this combination provides the best effectiveness in detecting all inconsistencies.
