Ultrasonic Testing (UT) – a volumetric method of non-destructive testing based on the propagation of waves in the material at ultrasonic frequencies.
In NDT inspections we use flaw detectors – measuring the time of wave propagation in the tested material and probes (transducers) – implementing and receiving oscillations with relevant frequencies.
Ultrasonic Testing is a widely recognized method of NDT for materials and structures condition evaluation.
Our NDT operators have all the necessary qualifications to perform Ultrasonic Thickness Measurements (UTT), including through-coatings testing, conventional ultrasonic testing and advanced ultrasonic technique – Phased Array (PAUT).
Magnetic Particle Inspection (MPI) – one of the electromagnetic methods based on applying small magnetic particles on the surface of magnetizing object material.
MPI is one of the basic NDT methods used to detect surface breaking cracks and subsurface defects (up to 2-4mm under the surface). Thera are two basic techniques of Magnetic Particle Inspection – colour and fluorescent, depending on kind of applied particles/ink and environmental conditions (white light or UV-A radiation).
Visual Testing (VT) is a basic method of non-destructive testing which should be applied before any other inspection to detect and evaluate surface flaws.
Visual Testing method can be applied during material manufacture process and exploitation. VT can be performed with “bare” eye or using specialized equipment (magnifying glass, mirror, endoscope, video endoscope, video camera, etc.).
ACFM® (Alternating Current Field Measurement) is one of the non-destructive electromagnetic methods. It’s main purpose is to detect and size (length and depth) surface breaking cracks in magnetic and non-magnetic metals.
The ACFM technique introduces an alternating current into the surface of the component to detect defects. The presence of a crack disturbs the electromagnetic field and the return signal is converted to data, in real time, so that the operator is alerted to the presence of a defect. This results in cost and time saving benefits, which gives ACFM users and operators a great advantage over the popular MPI method.
Non-destructive testing (NDT) is a group of inspection methods (surface and volumetric), which give information about properties of material being tested without changing its structure. NDT examination is commonly used in design, manufacturing and exploitation sectors. The main purpose of non-destructive testing is to detect and evaluate flaws in the material, both technological and exploitation.
We provide NDT services, including surface (VT, PT, MPI, ACFM) and volumetric (UT, UTT, PAUT) methods, as well as inspections, acceptances, technical consulting and supervision. We've also extended our service offer by hardness testing (Leeb method).
You are welcome to get familiar with our offer, which includes:
Penetrant testing (PT) is one of surface methods of nondestructive testing, which is used to detect surface-breaking defects.
Penetrant testing requires the test surface to be properly prepared (any dirt, grease or paint needs to be removed, and defects need to be "opened") and special chemical products to be used:
The penetrant testing method is commonly used to inspect nonmagnetic materials, such as austenitic steels, magnesium, aluminum and nickel based alloys, titanium and some composites. There are two possible techniques for penetrant inspection: visible dye or fluorescent, in which the application of UV-A radiation is required.
Hardness testing is one of the most common withstand tests, giving an information about mechanical properties of materials.
While constructing parts for machines and devices, the right choice of a material is essential for the optimum hardness of elements for specific work conditions.
If the hardness is too high, surface of elements will "flake" or some parts will be exploited too quick. If the hardness is too low, surface of elements will be to soft for some applications. In both conditions wrongly chosen hardness will significantly reduce an element exploitation time or will even prevent machine or device to work.
