Along with the increasing requirements of customers, NDT tests are performed at every stage of production, inter-operational, acceptance and operational. They allow to confirm the absence of unacceptable defects, a detailed catalog of which is included in the applicable standards.
The main goal is to confirm the quality of the material, eliminate defective elements from the production processes and reduce the unreliability of the structures in use. Faster detection and removal of existing cracks, delamination, corrosion loss of thickness will extend the service life of a given structure and save costs of new construction and production downtime.
Visual tests are based on a thorough inspection of the surfaces of welded joints, and are the most effective way of inspecting products. These tests are obligatory for all types of structures, most often as a preliminary test preceding other tests. The inspections can be carried out at various stages of the welding process, mainly at the finished joints. If the customer’s requirements or the product standard require a more detailed analysis, we make them at the stage:
The employee who will perform the test will need access to control and production documentation, all necessary measurement tools are provided by our company.
Ultrasonic tests belong to the volumetric tz tests. informs us about the state of the entire studied space. It allows you to determine the size, amount and distribution of discontinuities in the material. The research uses the phenomena accompanying the propagation of waves with an ultrasonic frequency over 16,000 Hz, greater than the upper limit of audibility of the human ear. Ultrasonic tests are used in tests carried out during acceptance, production, final or periodic inspection during operation. UT non-destructive testing is used to test objects made of ferritic and austenitic steels, aluminum, magnesium, copper, copper alloys, lead, nickel, composite materials, such as sheets, castings, bars, forgings and in the examination of welded joints (welds).

The company has a PMI MASTER PRO 2 SPEKTROMETER. It is designed for precise analysis, quick identification and verification of metal samples.
The plasma generated during the measurement performed with the probe emits light, which is then led to the PMP via optical fiber. There, it is subject to spectral analysis and measurement with CCD (charge-coupled devices, photosensitive semiconductor systems).
A specific area of the measured spectrum can be assigned to each element.
The PMP device is operated with the supplied software, which displays the analysis result on the screen.
These tests are the oldest method of non-destructive testing. Penetration tests are based mainly on the use of the capillarity phenomenon, i.e. the penetration of liquid into capillaries. The surface tension of the liquid, the wettability of the material and the gap width play an important role here. In welding, they are used to detect welding imperfections, in particular to reveal discontinuities of the material emerging on the surface of the welded joint. Penetrant testing is suitable for detecting non-conformities such as cracks, pores, sticking, and lapping that are open and come to the surface. Penetrant testing can be performed on a variety of metallic and non-metallic materials, in addition to porous materials. They are performed after the VT test and removal of unacceptable non-conformities.
In ultrasonic thickness tests, the basics of classical ultrasonic tests of wave transit time and its amplitude (echo technique) are used. We perform wall thickness measurements using the A-scan point method or in combination with the B-scan method, i.e. wall thickness scanning with a graphic representation of the material cross-section. The equipment we use allows us to take measurements without removing the protective paint, and to measure by scale and at high temperatures.
