Register of certified welding materials NAKS: what is it and what documents need to be sent?

Sooner or later, any manufacturing enterprise may require confirmation of the qualifications of working personnel and approval of welding processes. This event is called certification, and it is necessary both for welders and for all workers in the production workshop. Welding technology certification is usually carried out by NAKS (National Welding Control Agency). It has many important nuances and features that must be taken into account during the process.

What legal documents governs

The documentation according to which the agency operates is approved by the Gosgortekhnadzor of the Russian Federation. The standards describe:

who should conduct the certification;
forms of completed papers;
test types.

After the inspection, the organization that provided samples of welding materials receives a certificate, and at the same time it is included in the unified NAKS database.

Perm Test » Registration of a NAKS welding certification certificate

Currently, it is impossible to imagine industrial production in which there is no need for welding work. Due to the complexity and potential danger of this type of work, their quality is subject to state control. For these purposes, NAKS (National Welding Control Agency) was created - a self-regulatory organization that promotes the centralization of the welding production certification process. The activities of this organization involve the development of documentation related to the certification of welders and the welding process, coordination of the certification process itself and verification of existing certification centers and is regulated by the charter, as well as regulations of the welding process certification system.

State control over the certification procedure for welders and welding equipment is carried out by Rostekhnadzor, its representatives are required to be present on the certification commission.

State control in the field of welding work is carried out in the following areas:

certification of welding specialists;
certification of welding technologies;
certification of welding materials;
certification of welding equipment.

Let's look at these types of certifications in more detail.

Certification of a welding specialist is carried out to confirm that he has the required level of theoretical knowledge and practical skills. A welder who has received a NAKS certificate has the right to work at facilities controlled by Rostechnadzor.

The presence of certified welding specialists at the enterprise allows us to draw appropriate conclusions about its real organizational and technical capabilities for carrying out welding activities.

There are four classes in the certification system:

1st class - certified welder,
2nd class - certified master welder,
3rd class - certified welding technologist,
4th class - certified welding engineer.

The certificate obtained based on the results of the 1st grade certification is valid for two years, and for the certification of grades 2-4 - from three to five years, then the document must be renewed.

Certification of welding technologies

In accordance with the requirements of current legislation, welding and surfacing technologies used during installation, repair or reconstruction of hazardous production facilities (equipment, buildings, structures) are also subject to mandatory certification. Accordingly, technologies that have not passed the necessary testing are prohibited from being used. The validity period of the welding certificate is four years.

Certification of welding materials

In accordance with the provisions of the law, all welding materials coming into circulation for the first time, both produced in Russia and imported from abroad, are subject to mandatory certification. The initiative for its implementation can come either from the manufacturer of the materials themselves, or from their supplier (in the case of foreign-made welding materials - the importer), or from the customer. The validity period of the NAKS certificate for welding materials is three years.

Certification of welding equipment

Russian legislation contains a requirement for mandatory certification of welding equipment, which is used in the production, installation, reconstruction and repair of equipment and hazardous production facilities. During certification, the ability of the equipment to provide the necessary technological characteristics of various types of welding, as well as the proper quality of welded joints, is checked. The appropriate certificate must be obtained for welding equipment for gas, resistance, arc welding and for welding polymers.

Consultation with a specialist Call me back

Why is certification necessary?

If the manufacturer of welding materials does not ensure stable quality of its products, then defects may appear during the creation of permanent connections:

pores;
fistulas;
cracks.

This may occur due to a violation of technology: erroneous addition of elements during creation, violation of temperature conditions during the process.

As a result, welded joints may fail during construction, inspection, or operation.

Algorithm

In order for industrial institutions to pass the certification test, the personnel must include at least one third-level welding specialist and at least two welders. They must be certified, they must have supporting documentation.

To obtain a NAKS certificate of certification of welding technology, you must submit documents from the enterprise that manufactures the product. An application with documents is submitted to the supervisory authority.

To obtain a certificate of certification of welding materials and technologies, you need to collect documents from the list below:

Articles of association.
Diagrams of the location of pipe communications and welding equipment in the production workshop.
An agreement concluded with a laboratory that controls the quality of welds at the enterprise.
It is imperative to collect all certification documents for the welding equipment used, for metals and other materials used to manufacture products.
NAKS certificates of all employees, they must indicate the level of qualifications.

If all documentation is in perfect order, then the production organization will be allowed to audit. Specialists must draw up a plan indicating all the important criteria that are taken into account during production. If the production establishment passes the inspection, a certificate is issued that is valid for 4 years.

The certificate of certification of welding materials and technologies received by NAKS is considered confirmation that the organization has passed the necessary checks and complies with the standards. It must prove that the production employs highly qualified specialists, the workshop is equipped with the required equipment and materials, which have also been certified.

What is

The verification procedure is carried out depending on the type of welding materials. The sequence is described in the developed documentation:

General tests - audit of papers that accompany welding documentation for compliance with GOST and TU.
Practical tests - carried out in special laboratory conditions after creating control seams. The samples are then tested to ensure they meet the stated specifications. For this purpose, non-destructive testing methods are used, as well as mechanical tests for strength, tensile, corrosion and other tests.
Additional tests are necessary to check gas mixtures.

The expert commission gives an opinion, after which the final documentation is filled out.

Welding certification NAKS. Control instructions

It often happens that in order to carry out installation, repair, production and reconstruction of technical devices at hazardous industrial facilities, the Customer hires a specialized installation organization, the range of services of which also includes welding work.

Before starting welding work, it is necessary to check the permitting documentation of the installation organization. Only after checking the permitting documentation can the installation organization receive permission to begin work. As a rule, the decision on permission to work is made by the technical supervision (construction control) of the Customer. Such a specialist must have the necessary knowledge in the field of welding production, and must also check and pay attention to the presence of the following documents in the process of checking the permitting documentation of the installation organization:

Certificate of NAKS on the readiness of the applicant organization to use certified welding technology in accordance with the requirements of RD 03-615-03

Certification of the NAKS technology confirms the fact that the installation organization has the technical and organizational capabilities, qualified personnel to conduct welding work in accordance with the certified technology, as well as control that the welded joints implemented in the conditions of a specific production using the certified technology comply with the requirements of regulatory documentation to hazardous production facilities.
Just having a welding certification certificate is not enough. It is important to pay attention to what welding method and what group of technical devices it is issued. It is also necessary to check the validity period of the certificate.

If necessary, the authenticity of the certificate can be checked on the NAKS website, where by the certificate number or the name of the organization you can find out whether the certificate is included in the NAKS register or not.

It is important to remember that an annex must be prepared for the certificate, which contains the following data about the established scope of the production certification of the technology:

welding method
nature of the work performed (manufacturing, installation, repair and reconstruction)
groups and brands of basic materials
welding materials
diameter range
thickness range
seam type
connection type
type of connection
cutting angle
welding position
presence of heating
presence of heat treatment
type of electrode coating

Based on this annex to the certificate, it is necessary to assess the ability of the installation organization to carry out a set of welding works provided for by the working documentation or the welding production project (WPP).

Certificate of certification of welding equipment in accordance with the requirements of RD 03-615-03

Certification of welding equipment by NAKS is carried out to check the ability of the equipment to provide specified technological characteristics for various welding methods, which determine the required quality of welded joints in the manufacture, installation, repair and reconstruction of technical devices used at hazardous production facilities.

During the verification of this certificate, first of all, it must be revealed that the serial number on the welding equipment corresponds to the number specified in the equipment certification certificate. The name and brand of the equipment must also match.

Also, in the certificate of certification of welding equipment, it is necessary to check the compliance of groups of technical devices for compliance with the facility at which welding work is carried out (GO, GDO, KO, KSM, MO, NGDO, OTOG, OKHNVP, PTO, SK). Simply put, is the presented welding machine suitable for carrying out work, for example, on the installation of boiler equipment.

The type of welding assumed and specified in the working documentation or welding work project (RD, RAD, MP, etc.) must correspond to that specified in the certification certificate.

The validity period of the certificate is also subject to mandatory control. Equipment with expired certification certificates are not allowed to perform work.

The authenticity of welding equipment certification can be checked on the NAKS website.

Welding production specialist certification certificate

Certification of welders NAKS is a set of documents, according to which a welder is allowed to work at hazardous production facilities. It is worth noting that work carried out at hazardous production facilities must be performed not only by certified welders, but also under the supervision of a level II or III welding specialist. Uncertified personnel cannot be allowed to carry out work.

Welding production specialists have the following certification levels:

Level I – welders who have the right to perform welding work using specific welding methods, both manually and by mechanized or automated methods.

Level II – specialists (craftsmen, work producers) who have the right to give instructions to welders in written or oral form, as well as to exercise guidance and technical control during the welding process.

Level III – specialists (technological engineers, laboratory employees) who provide, as well as carry out management and technical control of welding work. Level III welding production specialists have the right to develop and sign production and technological documentation for welding work (welding production projects and technological maps).

Level IV – specialists who are the managers of the enterprise’s welding service (chief welder), who provide management and technical control of welding work, and also have the right to develop and approve guidelines and regulatory documents for the performance of all types of welding work.

It often happens that checking the documents of welding production specialists is limited only by their availability. But no one pays attention to which hazardous production facility was certified by NAKS. It is important to remember that a specialist certified in gas equipment (GO) does not have the right to carry out work on the installation of oil and gas production equipment (OGPE).

The certificate of a welding production specialist must be accompanied by a certification protocol. The protocol contains information about the groups of dangerous technical devices for which the specialist is certified, as well as the name of the organization in which the specialist worked at the time of certification. The certificate will be valid even if the specialist changes his place of work several times.

In addition to the NAKS certificate, a welding production specialist must be certified according to safety rules in Rostekhnadzor for hazardous production facilities specified in the certificate.

Certified welders must have a certificate of the established form, which reflects and must verify the following data:

type of welding (RD, RAD, MP, etc.)
type of parts (T - pipe, L - sheet, T+L - pipe + sheet)
types of seams (SSh - butt weld, USH - fillet weld)
group of welded material (M01, M02, etc.)
welding materials
thickness of parts
outside diameter
welding position
type of connection

Certified welders are allowed to perform welding work at hazardous production facilities in accordance with RD 03-495-02 and PB-03-273-99.

It is not uncommon for installation organizations, in order to save money, to have only one certified specialist or not at all. Thus, they are forced to illegally attach other people’s copies of certificates of specialists, often not working in this organization, and sometimes even forged certificates. Therefore, the authenticity of the ID must be verified on the NAKS website.

Certificate of certification of welding materials in accordance with the requirements of RD 03-615-03

When checking the quality of welding materials, it is necessary to pay attention not only to the availability of certificates, but also to the presence of a NAKS certificate of certification of welding materials.

Such certification is necessary to verify the compliance of the actual technological properties and characteristics of welding materials with the properties and characteristics specified in the accompanying documentation and the requirements of current standards, technical specifications and other regulatory documents for welding materials. Based on the certification results, the possibility of using welding materials during installation work is determined in accordance with the declared welding technology.

The certification certificate for welding materials contains the following data:

brand of welding materials
standard size (diameter)
welding method (RD, RAD, MP, etc.)
groups of basic materials (M01, M02, etc.)
groups of technical devices (KO, GO, SK, OKHNVP, etc.)

The type or brand of welding materials must correspond to those specified in the working (design) documentation or the welding project. It is also necessary to check the validity period of the NAKS certification. Typically, the validity period is 3 years.

The authenticity of the certificate of certification of welding materials can be checked on the corresponding page of the NAKS website. The certificate must be entered in the NAKS register.

What welding materials are required?

NAKS certification is required for the following materials:

protective gas mixtures - carbon dioxide, argon, helium;
flammable gases – butane-propane, acetylene;
welding pastes to protect the welding zone and fluxes;
tapes and powder self-protective materials : powder wire for mechanized (semi-automatic) and automatic welding;
non-consumable electrodes for electric arc welding - from tungsten and alloys;
consumable electrodes for electric arc welding;
wires with a solid cross-section for use on semi-automatic or automatic welding machines.

Nax certified electrodes

The assignment and issuance of certificates for electrodes is a guarantee of high quality consumables that are used for different types of welding work. At the moment, NAKS certification is available in all regions of the country, thanks to which it is possible to track how high-quality welding consumables are entering the market. Many online stores offer electrodes certified by NAKS.

NAKS is the National Welding Control Agency. It is the central body of the Welding Certification System in the country. Here decisions are made on the directions, methods, structure, work rules and functions of welding. NAKS unites more than 113 organizations and 200 certification centers, as well as approximately 700 certification points that issue certificates on the quality of electrodes to manufacturers. Certification centers are available throughout the country and have also been established in other countries. Basically, they are created on the basis of industrial enterprises or at the welding department in technical universities in Russia.

Today NAKS is the largest Russian professional community of welding specialists. This service is gaining increasing interest abroad as well. The certification centers provide everything for training first-class specialists: technicians, engineers, craftsmen and welders. Teaching aids include specialized literature and regulatory documents. Also, for improved assimilation of the material, a video is shown, and the classes themselves are taught by experienced specialists and instructors.

In our age of technology, it is simply necessary to be a specialist in your field in order to carry out welding as efficiently as possible and at the same time save time and energy resources. It is worth remembering that a welder at work risks his health and, sometimes even his life, every day. Therefore, welders need to be high-level specialists in order to protect themselves from danger.

Now let's talk about electrodes that are certified by NAKS. Below are the main brands of electrodes that have been certified and received NAKS certificates:

UONI 13/55 - electrodes that have proven themselves to be one of the most effective when welding structures, which operate at low temperatures and guarantee trouble-free operation of welding structures even for decades;
UONI 13/45 is a guarantee of obtaining ductile welds. No hydrogen content in the deposited metal ensures the absence of cracks and other types of defects;
ANO-21 is the best that can be taken from UONI and MR electrodes. These electrodes can be welded in any weather conditions, on almost any welding equipment and on metal with any surface;
MP-3 – electrodes that can be used to weld any, even heavily contaminated, metal;
OZS-12 - similar to ANO-21, but differ in that they can be used even at reduced current;

Use electrodes certified by NAKS, and the quality of your welding will always be at its best.

Types of certification

Depending on the specifics of the company’s work and the need for verification, the following certification is carried out:

primary – if the product has never been tested in NAKS laboratories before;
additional - if the inspection has already been carried out previously, but changes in technology occurred in production (using welding materials of this type), or the manufacturer decided to expand the scope of application of its products;
periodic - carried out once every three years if the product has been tested (passed the initial tests), but regular re-certification is necessary. Moreover, if during this period none of the customers have made justified claims to the manufacturer, then the procedure at the NAKS center is carried out according to a simplified scheme;
extraordinary - it is passed by those welding materials that have already been tested earlier, but then the State Mining and Technical Supervision of the Russian Federation introduced a ban on their use. Upon recertification, the manufacturer receives a new document.

Technology certification

The NAKS register includes welding materials and technologies with a high degree of danger, which, according to the legislation of the Russian Federation, cannot be used without certification. The audit is carried out by the National Welding Control Agency.

Among the most dangerous objects of the organization that are used in production are:

elements with an oxidizing effect that can support combustion processes;
gas mixtures with rapid ignition;
toxic elements with chemical and biological composition;
components that have a negative impact on the environment;
melts of ferrous and non-ferrous metals.

Welding work at these facilities is permitted only after passing a welding technology test. The NAKS Center conducts an audit of the quality of welding works using practical research methods.

If the technology is being used for the first time or it has undergone some changes, then an initial check will be required. Every 4 years, production establishments must undergo periodic audits. Also, verification is required if the technology has not been used for a year.

Main brands of electrodes certified by NAKS

In order to obtain comprehensive information about which electrodes have passed the NAKS certification and received certificates of conformity, as well as find out the details of such certificates, including their validity periods, you can refer to the NAKS register.

To obtain information, you can log on to the official website of the National Welding Control Agency and go to the “Welding Production Certification System” section. The menu in this section will allow you to enter the subsection “Certification of welding materials”, where a special register is located. In this register you can obtain all the necessary information about welding materials that have passed official certification.

In order to clarify information about whether a specific brand of electrodes has passed certification, you need to know the type of electrode being tested, as well as its brand or manufacturer. If information about the brand and manufacturer is unknown, you will have to search manually through a list of five hundred items.
