Certification of welders according to NAKS (MMA +MIG/MAG)

Home Training and certification Personnel certification Certification in the field of NAKS

offers its assistance in training and certification of welders and welding production specialists at NAKS.

The presence of NAKS certificates for welding production is required for welders and specialists in order to perform work at hazardous production facilities, in accordance with the requirements of Rostechnadzor.

Certification/training of welders and NAKS specialists is regulated by the following documents:

PB 03-273-99 - “Rules for the certification of welders and welding production specialists.”
RD 03-495-02 - “Technological regulations for certification of welders and welding production specialists.”

Welders/specialists are certified in independent certification centers that are part of the NAKS structure.

NAKS certification of welders/specialists is divided into 4 levels:

The first level (I level)
is for welders. Certification gives the right to perform direct welding work.
The second level (II level)
is for welding production masters. Certification gives the right to control the entire welding process.
The third level (III level)
is for welding production technologists specializing in welding production. Certification gives the right to determine the technology of the welding process, develop and sign technological maps.
The fourth level (IV level)
is for welding engineers. Certification gives the right to sign and approve the documentation according to which welding work is carried out at the enterprise.

Cost of NAKS certification and training for welders and specialists:

Certification	Price
Certification of level 1 welders	from 15,000 rubles
Certification of specialists of levels 2 and 3	from 18,000 rubles

The exact cost is formed on the basis of the Questionnaire and depends on the level of certification, the number of specialists and the necessary parameters of welding production.

Send us an application for certification, and our managers will calculate the cost of the services you need.

OTU groups (hazardous technical devices).

Certification of welders and NAKS specialists can be carried out in any region of the Russian Federation, regardless of where the specialist plans to work.

Certificates of welders and welding production specialists give the right to perform only those welding works for which he is certified.

Information about the documents received based on the results of certification of welders/specialists is entered into the open register of NAKS.

Validity period of documents for welders and NAKS specialists:

2 years – for level 1 welders;
3 years – for level 2 craftsmen and level 3 technologists;
5 years – for level 4 engineers.

Upon expiration of the certificate, it is extended; the welder/specialist undergoes periodic certification. You can submit documents for extension no later than 1 month. before the end of their term. Periodic certification can be completed no more than twice. Next, you must again undergo primary certification.

About NAKS certification

NAKS is an acronym that stands for National Welding Inspection Agency. It is part of the welding production certification system. The organization and the technology itself are subject to control. Additionally, checks are carried out regarding materials, equipment and other things.

In many industries, the welding profession continues to be the main one. Persons working in this specialty must perform a whole list of different types of work. That is why there is a need for certification, since representatives of the authorized body want to know that the company will provide quality services. NAKS performs the following actions:

develops methodological documents;
controls the resolution of issues arising in the above area of activity;
monitors the work of certification centers;
constitutes an expert commission that will conduct certification;
is engaged in maintaining a register in which information about the certification performed and the results obtained is entered.

Only persons who have received the appropriate rank have the right to take part in the procedure. It is assigned after a person has completed specialized training and passed the relevant exams.

Carrying out the procedure

First of all, you will need to prepare documents. The list will need to include:

application requesting access to certification;
medical certificate demonstrating the absence of contraindications;
documents on the education received;
extract from the work book;
protocols confirming the completion of safety inspections.

If certification is carried out by NAKS in Zheleznodorozhny, you will have to pass a practical and theoretical exam. Initially, attention is paid to practice. If the employee does not pass it, the test ends there. Control is carried out on the basis of current GOSTs and documents developed by NAKS.

If you pass the practice successfully, you will have to pass the theory. It depends on the level for which the person is applying. You must answer at least 15 questions. If you need to get levels 2-4, the number of questions increases to 20. Usually the test is taken electronically using computers. However, sometimes the procedure is carried out in simple written form. The theoretical part is considered passed if the person gives correct answers to at least 80% of the questions. If the test fails, a retake is acceptable. However, it is completed within 3 months.

It is recommended that you complete training before taking the exam. You can order it from us. It is permissible to master the material remotely. The specialist will not have to stop working. For training, it is enough to have access to the Internet and a device that allows you to familiarize yourself with the information. We are ready to adjust the training schedule to suit your needs. The work is carried out under a contract.
