Modern machinery, advanced technologies, and certified processes are crucial in industrial production. Behind each of these elements, however, are people, their knowledge, experience, and ability to responsibly assess the quality of work performed.
That is why at FEMET we consistently invest in the development of our team’s competences.
In May 2026, Łukasz completed specialized training in visual testing (VT) at levels 1 and 2, organized by TÜV Rheinland Polska. The knowledge he acquired and updated forms the basis for extending his certification at the Łukasiewicz Research Network, the Upper Silesian Institute of Technology, and the Welding Center.
What is VT visual testing?
Visual testing, abbreviated as VT for Visual Testing, is a non-destructive testing (NDT) method.
They allow for the assessment of the surface condition of a material, element or welded joint without disturbing its structure and without causing damage to the tested product.
Visual examinations can be conducted directly, with appropriate lighting and access to the surface, or using specialized equipment such as:
- magnifying glasses and measuring instruments,
- feeler gauges,
- inspection mirrors,
- industrial endoscopes,
- videoendoscopes,
- devices for controlling observation conditions.
Although visual inspection may seem like a basic assessment method, its proper implementation requires specialized knowledge. The person performing the inspection must be familiar with the appropriate standards, observation conditions, acceptance criteria, and how to document results.
40 hours of theory and practical preparation
The VT 1+2 training conducted by TÜV Rheinland Polska included 40 hours of theoretical and practical classes.
The edition in which Łukasz participated took place from May 11 to 15, 2026. The program covered issues related to the qualification of non-destructive testing personnel, the physical basis of the method, the properties of materials, and the assessment of non-conformities occurring in industrial products.
During the training the following topics were discussed, among others:
- principles of qualification and certification of NDT personnel,
- basics of optics and anatomy of the visual organ,
- corrosion of materials,
- lighting conditions and proper observation,
- characteristics of the equipment used during the inspection,
- industrial endoscopy,
- evaluation of welded joints, castings, forgings, pipes and plastically processed products,
- detection and classification of non-conformities,
- selection of appropriate examination techniques,
- working with standards and technical specifications,
- preparation of inspection reports,
- developing written test instructions.
The practical part included conducting tests at various stages of the production process, assessing detected non-conformities and properly documenting the results.
What discrepancies can be detected during visual inspection?
A properly conducted visual inspection can detect visible material and welding inconsistencies, such as:
- cracks,
- surface porosity,
- flooding,
- incomplete filling of the welding groove,
- incorrect shape of the weld,
- shifts and deformations of elements,
- ślady korozji,
- surface damage,
- other deviations from the technical documentation or adopted quality criteria.
Simply identifying nonconformities is not enough. A qualified person must also be able to evaluate the results in accordance with applicable standards, customer requirements, and project documentation.
Scope of competences at the VT2 level
The second level of qualification involves a broader scope of responsibility than just performing inspection activities in accordance with the instructions received.
Competencies developed during VT2 training include, among others:
- selection of research techniques for a specific task,
- determining the possibilities and limitations of the method,
- selection and checking of equipment,
- performing and supervising research,
- interpretation and evaluation of results,
- development of non-destructive testing instructions,
- collating results and preparing reports,
- providing guidance to less qualified personnel.
These are competencies that are important not only from the perspective of final inspection, but also of the entire process of manufacturing metal structures and elements.
Basis for extending the certificate at the Łukasiewicz Welding Center
Completing additional training and meeting the requirements for updating qualifications gave Łukasz the basis to extend his certificate at the Łukasiewicz Research Network, the Upper Silesian Institute of Technology, and the Welding Center.
The Centre conducts qualification and certification processes for non-destructive testing personnel in accordance with the requirements of the PN-EN ISO 9712 standard.
Certification provides independent confirmation of the competence of the person performing the tests. However, it does not replace internal procedures, employer responsibilities, or project-specific requirements. It is one element of a quality assurance system that must function in practice at every stage of production.
What does developing qualifications mean for FEMET clients?
For our clients, investing in staff development means, above all, greater control over the quality of implemented components and structures.
Current knowledge and appropriate qualifications allow:
- identify potential inconsistencies in advance,
- reduce the risk of costly corrections,
- more precisely control the execution of welded joints,
- maintain documentation in accordance with project requirements,
- communicate inspection results more efficiently,
- maintain production repeatability,
- carry out orders for sectors with increased quality requirements.
At FEMET, we develop both our machinery and the competences of the people who operate production processes, conduct inspections, and are responsible for compliance with documentation.
Technology creates opportunities. It is the knowledge and responsibility of people that determine how they will be used.
Congratulations to Łukasz!
We congratulate Łukasz on completing another specialist training course and consistently developing his knowledge in the field of non-destructive testing and quality control.
Each new or renewed qualification in our team strengthens the competencies of the entire company. It also allows us to expand FEMET’s offerings and respond to the increasingly sophisticated requirements of clients from various industry sectors.

Frequently asked questions
What does VT stand for?
VT stands for “Visual Testing.” It is a non-destructive testing method used to evaluate the surfaces of materials, components, and welded joints.
Do visual inspections cause damage to the tested item?
No. VT testing is a non-destructive method. It allows you to inspect a component without damaging its structure or limiting its subsequent use.
What is the difference between VT1 and VT2?
A person with a first-level qualification performs tests according to prepared instructions and under specific supervision. The second-level qualification encompasses broader competencies, including technique selection, result interpretation, compliance assessment, preparation of instructions, and reporting of test results.
