How does a welding course work?

The course consists of a theoretical part, which lasts two days, and a practical part. In the theoretical part participants gain the basic and specific knowledge needed to work as a welder. In the practical part instructors work with each participant individually and adapt the exercises to their level of experience and the client’s needs. The length of the practical part depends on the candidate and their previous knowledge.

We run welding courses in line with IIW, EWF and DVS guidelines and ISO education standards, using flexible European principles.

Yes. After the course you can go through certification and obtain an international welder certificate. Certification takes place in the welding shops of the Institute in Ljubljana or Maribor, and on request at the client’s site. More on the page Welder certification.
