Performing NDT tests
Rope access and the alpine skills of our team allow us to carry out NDT projects both at heights and in hard to reach places. In order to detect various types of abnormalities, we use several testing methods, adjusting them individually to a particular case.
Non-destructive weld testing methods
Visual tests (VT)
most often treated as a preliminary examination, preparing for the application of another NDT method. They can be performed with the unarmed eye or with the use of appropriate equipment such as an endoscope or magnifying glass. Visual examination allows to detect, among other things, welding and hardening as well as corrosive defects.
Penetration tests (PT)
undertaken in the next stage after the visual test. The PT method is most often used for metal products, it works well for the control of non-magnetic materials, such as aluminum and stainless steel. Used in the verification of hard to reach elements.
Magnetic-particle test (MT)
used for detecting incompatibilities that are at a small depth. It is also a method used to locate the most dangerous discontinuities, including collapses, entanglements and tears. The component being tested is magnetized during the process.
Eddy current test (ET)
used primarily in the aviation, steel and engineering industries and for weld testing. The assessment of material condition is based on the analysis of several key factors – amplitude, electromagnetic field variation values, voltage current and phase shift.
Ultrasonic test (UT)
ultrasonic waves are emitted into the test material. A beam is formed and its reflected part is processed to take the form of a light pulse, which is visible on the defectoscope screen. The UT test is used for the detection of flat irregularities.
Other methods we can offer include ultrasonic thickness measurements (UTT) and assessment of technical condition of the structure.
