Radiographic testing (RT) is an NDT method in which X-ray or gamma radiation passes through the tested component and creates an image of its internal structure.​ This makes it possible to quickly and reliably detect typical material discontinuities in castings and welded joints, such as cracks, gas pores, inclusions, voids or lack of penetration.

At ULTRARENT we complement proven film-based radiography with digital techniques (DR/CR), which significantly shortens the waiting time for results, enables fast analysis of radiographs and makes archiving easier. In practice this means greater detectability, which translates into better control at the production stage, less risk of error, and a significantly more efficient completion of the inspection process. Testing is carried out in accordance with EN ISO 17636-1, by inspectors certified to EN ISO 9712, level 2 and 3.

In practice this means:

Effective detection of internal discontinuities such as: cracks, porosity, inclusions and lack of penetration
An unambiguous, permanent test result in the form of a radiograph – easy to document, verify and archive
Faster access to results when using digital (DR) or computed (CR) radiography – no need for chemical film processing
Greater efficiency and shorter inspection time thanks to digital solutions, helping to reduce service downtime
Quality control of welded joints in pipelines, industrial installations and steel structures
Testing of tanks and pressure equipment, where an assessment of the interior of the component and confirmation of quality are required
Diagnostics of castings and components with complex geometry for porosity, inclusions and voids
Maintenance inspections (service/plant maintenance): verification of repair welds and assessment of component condition before returning to service
RT inspection of a steel tank – DÜRR DR 2430 digital detector at a circumferential weld

Radiographic testing is a proven inspection method, but in practice it is not always suitable for every case. That’s why we help select the right technique for the specific task and its purpose, one that will work best under the given operating conditions.

Badania ultradźwiękowe (UT)

Ultrasonic testing (UT) is an NDT method using ultrasonic waves to detect internal and surface discontinuities in tested components.

Replace radiographic testing:

Phased Array Ultrasonic Testing (PAUT) is an advanced NDT method in which a multi-element ultrasonic probe generates an electronically steered beam at multiple angles in a single scan, enabling a full volumetric assessment of welds, castings and structural components.

Digital radiography in NDT covers the DR (Digital Radiography) and CR (Computed Radiography) techniques, in which X-ray or gamma radiation passes through the component and an image of the internal structure is recorded by a digital detector or imaging plate instead of classic film.

Ultrasonic testing (UT) is an NDT method in which an ultrasonic wave is introduced into the tested component via a probe, and the reflected signals are analysed in order to detect internal and surface discontinuities.

Depending on the material, access and type of tested component, we also recommend surface testing methods:

Penetrant testing (PT) is an NDT method used to detect discontinuities open to the surface, based on the capillary penetration of a penetrant into cracks.

Magnetic particle testing (MT) is a non-destructive testing method used to detect surface and near-surface discontinuities in ferromagnetic materials such as carbon and low-alloy steels.

This is a classic non-destructive testing (NDT) method in which X-ray or gamma radiation passes through the tested component and the result is recorded on radiographic film. It is used, among other things, to assess welds, castings and other components when volumetric inspection and a permanent record of the result are needed.

RT very effectively reveals internal and volumetric discontinuities, such as gas pores, inclusions, voids, and many typical welding defects (e.g. lack of penetration). In the radiographic image, defects are visible as differences in density resulting from changes in the thickness or density of the material.​

It all depends on the specific case, the client’s requirements, regulations, and the thickness and geometry of the tested component. The method is very flexible and universal. In most cases it provides unambiguous results and a permanent, physical record of the test in the form of a radiograph, which can be archived and presented as evidence in quality documentation.

The testing time depends on the thickness, geometry and accessibility of the tested component, as well as the number of exposures required to carry out the test correctly. In addition to exposure time there is also the film processing stage, which usually extends the whole inspection process compared with digital techniques (CR/DR), as well as the subsequent interpretation of the resulting radiographs.

Usually yes – the radiation source must be placed on one side and the film on the other side of the tested component, in order to record the image formed after the beam passes through the material being examined. In the case of pipeline testing, access to the inside of the pipe is not a necessary condition.

It is safe provided that safety procedures and radiation protection measures are strictly followed, including designating and securing zones and dosimetric supervision. Because ionising radiation is present, marking and controlling access to the zones during exposure is extremely important. Testing using digital techniques shortens exposure time, reduces the doses received and improves safety.

Not always – although UT and advanced ultrasonic techniques (PAUT, TOFD) can often replace RT, in many industries and applications radiography is required as the reference method. The choice of method should be based on standards, project specifications, and an analysis of risk and technical feasibility.
