Before the certification for welders and specialists who have a professional training in the field of welding production and having a practical skills at the level of PB-03-273-99 requirements and applicable to standard documents, a special training is conducted.

Special training should be carried out before certification (initial, additional, periodic and extraordinary).

After completion of special training ЮР-5ЦСП (Special training center) issues a certificate of special training passing.

Certification of welders (in accordance with the PB-03-273-99 and RD 03-495-02) consists of passing practical, general and special exams.

Certification begins with the practical examination of welders. If the welder does not pass the practical exam, then he is not allowed for further examinations and he is considered to be decertified. Welder can be certified again after additional practical training not earlier than 1 month and provided that he will pay for practice exam again.

Certification of welding production specialists involves performing of two exams: general, special (including a practical task).

Upon successful passing of the certification ЮР-3ГАЦ issues:

  • A certificate recorded in personnel register of certification system of welders and welding production specialists of National Certification Committee for welding production (NAKS).

  • Certification protocol signed by the chairman of a committee, committee members and representative of Russian Rostechnadzor.
