  2. Knows the requirements and organizes maintenance and calibration / verification of equipment and tools used in welding production.
  3. Can read the compliance of welding drawings with the standard EN ISO 2553.
  4. Analyzes and evaluates the technical requirements for the welding structure.
  5. Distinguishes steel types, takes into account the effect of steel properties on weldability and implements measures to ensure weldability.
  6. Determines the methods of destructive inspection of welded joints according to the requirements of the standards.
  7. Knows the defects of welded joints, the causes of their occurrence and applies methods to repair and prevent them.
  8. Applies methods for prevention and reduction of residual stresses and deformations of welding structures.
  9. Implements measures to ensure occupational safety and safety in welding production.

Documents to be issued: School certificate if the course has been completed to the extent of at least 80% (introductory course for welding controller VT2 courses). 

Description of the learning environment: Both theoretical and practical parts take place at Pae 29, Tallinn. Safety and health requirements are guaranteed in the theory auditorium and workshop. To study the theory, we have 4 classrooms depending on the subject taught, each class can accommodate 30+ people. The theoretical part is issued at home to record knowledge electronically (on memory sticks). We also issue both personal protection and tools for practical training. 

Requirements for the trainer’s competence: Technical or industrial education / applied higher education; experience as an adult educator for 2 years.


Practice teacher: Vladislav Shrubkovskiy. 

Theory teacher: Tatiana Karaganova.
