For complicated work, employees certification is certified. This procedure is necessary for assigning a certain qualifying level. At the highest level of qualification, the employee is allowed to work on complex objects.

Are no exception and welders. To obtain admission to work, they pass attestation of NACS. This organization is based in order to control the quality of work in the welding sphere. In order to prevent problems with the passage of the exam, most specialists prefer to enjoy professional help in passing certification or attend courses of advanced welder's qualifications.

What is Nax certification

Certification of welding technology Nax is a confirmation of the professionalism of the welder. The received certificate indicates the competence of a specialist in his business, and also confirms that it is aware of the safety rules, has welding techniques and can work with complex welding equipment. Also, both practical classes are conducted as part of the program, the direction of which is determined on the basis of the professional responsibilities of the listeners.

The NACC abbreviation itself is decrypted as the "National Welding Control Agency". This organization certifies not only welders, but also engineering and technical workers related to welding work. Fit to the official registry NACS allows you to get admission to welding hazardous production facilities. Employees in this registry can also count on the increase in salary.

Who needs a certification of Nax

Not only welders and masters welders are applied for certification of NACS, but also technologists and engineers.

Verification of knowledge and skills of working personnel engaged in the welding area, provides such types of certification of the Nax:

  1. Welder Nax. A specialist who passed this exam receives a certificate providing admission to work in responsible objects. The duties of this employee include welding of any alloys and metals in all possible spatial positions. It also performs work on cutting, stroking and planing material. The welder, certified by the National Welding Control Agency, is able to impose seams of any type and take rational solutions in the event of an emergency;
  2. Master welder. Master requirements are much higher. Its competence includes not only welding. He also provides control over the activities of other welders and advise them in writing or oral form;
  3. Technologist. The duties of the technologist include the control of enterprise production processes, including welding;
  4. Engineer. The duty of an engineer is to control the compliance with the rules that regulate the welding process. The engineer is also responsible for the development of documentation that approves these rules.

Order of passage

To obtain admission to the welding process, you must contact one of the points of certification of Nax. To apply for certification and advanced training, you need to collect a number of securities.

In accordance with the requirements of the National Welding Control Agency, such documents for certification of NACS will be needed:

  • Documents that confirm the availability of special education;
  • Medpravka, indicating the absence of pathologies incompatible with welding;
  • certificate confirming the employment experience of the employee;
  • certificate confirming the rank of worker;
  • 2 photos 3x4 cm.

The procedure itself consists of three stages: a common, practical and special exam. First of all, employees passing certification take the practical part of the exam. As part of this exam, the skills of the welder are inspected, as well as knowledge of technological requirements, safety regulations and labor protection standards. If the welder could not pass the practical exam, then it can repeat the attempt in 30 days.

In the case of successful handling of the practical exam, the specialist receives admission to the general and special part. As part of these exams, a specialist skills check on the ability to perform complex welding compounds. It remains to add that the welder can simultaneously be certified in several types of work related to the welding sphere.

Welder Certificate Nax

In accordance with Rostekhnadprove's regulatory documents, in order to have the right to work on hazardous production facilities, welders and welding specialists (welding managers, master, pro-paper, technologists, technologists) should receive an EXC certificate. To date, almost all specialists working in the field of welding seek to confirm their qualifications. One way is the passage of certification or certification. The most common working system is Nax. It is important that after passing the CEX certification procedure, the certificate issued is entered into the publicly available registry. What makes it possible to check the welders and their employers information on the Internet and confirm the authenticity of documents. Serious large assembly companies are usually refused to take welding professionals without a corresponding certificate. Unfortunately, the validity period of the NACS welders is small and learning has to go back, which is quite expensive.

Decoding certificate of Nax

The NACK certificate is indicated on which object and which welding works can be performed by a welder undergoing certification. Certification is carried out depending on the level of training and groups of technical devices on which the welding production specialist will work.

All the topic studied during the training will allow successfully to pass the examiners when receiving certification, and enterprises get qualified specialists and become successful competitors in the enterprise market providing similar services.

Types of certification of Nax

To get a certificate of the NACK, you need to go through the certification procedure that is carried out by checking the practical skills and theoretical knowledge in accordance with the welding method and the group of technical devices, the welding of which performs the welder in production.

Certification of welders is divided into primary, extra, periodic and extraordinary.

Primary certification There are welders who did not have previously certified NACS. With primary certification, welders hand over common, special and practical exams.

Additional certification Welders passed by primary certification, to expand the field of certification. With additional certification, welders give a special and practical exams.

Periodic certification There are welders who end or expired the validity period of the NACS. With periodic certification, welders will hand over special and practical exams.

Extraordinary certification Welders are held after their temporary removal from work for violation of welding technology or repeating poor-quality welded joints. With extraordinary certification, welders hand over common, special and practical exams.

For good welding specialists in the field of welding, it is not difficult to pass the exams to get a certification certificate of the NACS. To make it successfully, you need to know the procedure for certification, there are a lot of any nuances in it. It is necessary to determine which to choose objects for certification, welding methods, materials main and welding, diameters and thicknesses. This stage is most important because it depends on the area of ​​certification and, accordingly, what specific work can perform the past certification of a person.

Start preparations for certification It is necessary with regulatory documents in accordance with which the certification of welders (I level) and specialists of welding production II, III, IV levels of vocational training Namely "Rules of certification of welders and welding specialists" (PB-03-273-99 ) and the "technological regulations for the certification of welders and welding specialists" (RD 03-495-02).

The next step needs to prepare the necessary documents and the application without which the certification will not allow

Documents for certification of Nax

To pass the procedure for certification of NACS and obtaining a certificate, it is necessary to prepare documents specified in the rules of welders and welding professionals:

  • Certificate of experience in the method of welding from an employer or a certified copy of the employment record;
  • Medical certificate of the established form of health status that a person can perform welding work and does not have any contraindications (a reference value is better to clarify in a specific attestation center, since it does not all require it, so you can avoid extra spending;
  • Documents confirming the qualification discharge on welding methods;
  • Documents on education, certificate, diploma or welder certificate;
  • Consent to the processing of personal data;
  • 3x4 photos in the amount of 2 pieces.

The procedure for certification of Nax

When all documents are collected, you can submit an application to the attestation center. We will usually be issued on the site of the center in which the certification will be held. Individuals undergoing certification an application can be helped to issue employees of the Center. It is very important to correctly determine the type of work, the area of ​​the certification that will be indicated in the certificate so that there are no "surprises" on the arrival. For each type of work, you need your certificate, therefore, the welder gets tolerance only to the type of work on which certification passes. It is not an option to ask for everything in a row, because the cost of certification will be incredibly high. Start this process is better in advance in many centers. Submitted documents can be considered for a very long time.

After the application with a set of documents will arrange employees of the NACS, prescribe the date of the passage of special training and the date of the exams practical and theoretical.

In a practical exam, welders must breed control samples and specialists perform a written practical task. After the practical exam, the welded samples are carried out, in satisfactory results, appoints the date theoretical exam, when unsatisfactory - the candidate is considered not to be certified;

On theoretical examination you need to pass tests according to the declared certification facilities and the welding method, for a specialist of the level on which certification passes. Theoretical exam is carried out in writing or using a computer. A welder is considered to be sustained testing if he replied correctly at least 80% of the questions asked. Questions must be said can get the most diverse, including those who are not relating to the direct work of a specialist. Therefore, it is nice to prepare for the theoretical exam, questions on certification can be found on the Internet.

All procedure Certification lasts from week to month. After the successful passage of certification, the protocol and the certificate is issued, the design of these documents can take place for several days, and even weeks. Upon receipt of the certificate, it is necessary to check your data and the area of ​​certification for compliance with the application. Despite the high price of certification, employees of some centers are quite negligent about their duties and errors are possible. The received certificate is considered valid if entered into the register of the welding production certification system. How to check availability in the registry read in the article How to check certificate of NACS on authenticity.

How much does it cost to get a certificate of Nax?

There are no single rates for certification. Prices are highly dependent on the specific attestation center in which you appeal and the required distribution area. On average, in Russia, the Welder Certificate of the Nax will cost 25,000 to 150,000 rubles, a welding specialist (master, pro-ITR) from 15,000 to 90,000 rubles. It is worth noting that this is quite expensive, the private commercial organization for alas and establishes prices at their discretion.

On the Internet, you can find a lot of ads with suggestions to buy Nax. At the same time, the cost will be much more than in the official attestation center and you need to not forget that you can get on scammers.

You can only restore the certificate by contacting that center that conducted certification. If this center is buried, then restore the documents is unlikely to succeed. Before the duplicates of documents are usually issued without charge charges. But in the extradition of the duplicate certificate of the NACS may refuse if you do not have paid it yourself when the certification is passed, and your employer. Then it will be necessary to get permission to receive a duplicate.

Personal certification

Nax for working personnel is carried out on four levels:

  1. Welder;
  2. Master welder;
  3. Technologist welder;
  4. Engineer welder.

The duties of the welder Nax include maintenance of metal structures on particularly dangerous objects. It is necessary to be able to weld any metals and alloys of any thickness in all spatial positions, as well as produce a surfacing, planing, cutting materials.

The competence of the certified Master-welder includes a distribution of written and oral instructions, which must be performed by the Welders of Nax.

Past certification of technologists-welders lead those divisions of the enterprise that are engaged in welding. Such experts are responsible for the sequence and quality of production work.

Welder engineers Nax are responsible, including for regulatory documents regulating the fulfillment of welding work of all types.

  4. Extraordinary Certification.

Primary is carried out for specialists without admission to various welding work. If the employee wants to acquire admission to various welding work, not specified in its certification certificate, then he needs to undergo additional certification. Periodic is made at the end of the term of certification documents in order to extend. But extraordinary certification will be required by welders, for some reason it turned out of work.

In addition, the NACx distinguishes the types of certification of specialists of welders on production, depending on the areas of work and types of technical equipment, with which a specialist works, for example, for oil and gas production (NDHO), gas (GO), various equipment used in chemical, dangerous, oil production (OKHNVP). Now the hotel technologies have been created in the Nax for the passage of the current certification of welders working on the NDGO, GO, OKHNP and other types of production equipment.

For some types of equipment, for example, the NDHO, the regulatory of the certification procedure takes into account the federal, corporate, sectoral methodological documents, for example, the regulatory documentation of Transneft OJSC.

As deciphered by Nax

To collect responsible structures will be trusted not every welder. And most likely the chosen candidate will be an employee who has passed the certification of Nax. Proper decoding Abbreviation: National Welding Control Agency. The name of the organization directly indicates the type of its occupation: monitoring the qualifications of specialists employed in the field of welding metal structures. Not only welders, but also engineers and new technologies pass the test stages in the walls of the institution. So, the Welder Certificate of the NACC is considered as such, the level of preparation of which meets the requirements of production standards.

Official site of the NACS Registry of welders - find yourself by last name

In addition to licensing employed in welding work, the agency is engaged in other functions:

  • development of standards and relevant documentation;
  • publication of methodological manuals;
  • introduction of technical recommendations in enterprises;
  • advisory support of complex processes;
  • Formation of commissions from experts and high-level specialists;
  • Personal certification.

Nax certification: Welder levels

Determining the level of qualifications is carried out in four levels:

  • First - Welder Nax . Organizations of independent experts give a specialist good for welding of responsible structures;
  • Second - Master Welder . Higher discharge specialist. It can not only perform, but also control the welding process, as well as to indicate the correctness of the implementation of specific technological operations. Recommendations may be made both orally and in writing;
  • Third - technologist . Engaged in the control of all welding processes in the enterprise;
  • Fourth - engineer . Services managers who are engaged in the control of welding processes of any level of complexity and are managers of relevant services.

It is important to emphasize that NACx certifies not only by specialists, but also equipment that is used to perform technological operations. In other words, the agency is designed to control the frames, the process and snap.

Welders pass three stages of testing: primary, re-and extraordinary. The purpose of events is two important points:

  • the company's readiness to perform a certain type of work on the compound of metals;
  • Confirmation of the level of training of specialists who are allowed to conduct responsible welding operations.

How to get certificate

Licensing of welding industry specialists is carried out in training centers listed in the Nax registry. Before applying for the passage of the relevant tests, the welder must collect a package of documents. It includes:

  • extract from the employment record with an indication of the work experience in the specialty;
  • Protocols for the delivery of safety standard;
  • photos;
  • Documents on the receipt of profile education;
  • Medical health certificate.

To check the maximum objective for rent two exams: on theory and practice. In cases where a test is not passed, it can be repeated in a month. First of all, practical skills of work are checked. If they have not been handed over, the applicant is not allowed to theoretical exams.

Employees of engineering must know the highly specialized requirements for specific areas of work. Quite often questions intertwined and affect not one, but several types of welding processes. Therefore, engineers should prepare for passing exams thoroughly and know technical standards and requirements of any kind of welding.

Attention! After a half-year break in labor activity in the specialty, regardless of the reasons, the welder or engineer must undergo certification and pass the Tax exams.

In the preparation process, it is recommended to study the documentation and standards that were developed by the agency specialists in the last period. In the training of welders, all themes and questions are included in the examination program are included. It is important to attend such courses on which:

  • TB welding works;
  • Basic welding equipment, auxiliary equipment and consumables;
  • Methods to eliminate welding seam defects;
  • Methods and types of welding process control;
  • Technology welding and soldering metals.

However, all the above themes welder can learn independently without a mandatory visit of advanced training courses. Just he will not receive a certificate on the passing of these courses. But it does not matter if the exams confirming the level of employee qualifications will be successfully submitted.

Certificate Nax

With a positive assessment of the test skills, a testimony of a special sample is issued. It is a confirmation that this specialist can work on all the objects under Rostechnadzor. Such a certificate is issued to welders of all levels without exception subject to a positive test outcome.

Repeated certification by welders should be passed only in two years, the masters and technologists will hand over attestation exams even less often - after three years, engineers are five years later. In each document, which is issued to experts in hand, refers to the type of work to which the specialist who received a document is allowed.

For example, if the CD abbreviation is in the certificate, it means that the welder has the right to work with manual arc welding, please - manual argon conversion welding. Other designations:

  • G - gas;
  • AF - automatic method under flux;
  • KTS - contact point;
  • MP - mechanized.

If the courses listener passed the exams for admission to several types of welding, then several abbreviations are affixed in the certificate, respectively. We emphasize that the document received is a kind of admission to the work on welding of responsible structures.

Certification of organizations and enterprises

If there are welding processes in the list of services of the company, then the structure itself is also subjected to NACC certification. The purpose of such an inspection is to confirm or refute the technical capabilities of the company in performing a certain type of work. Experts check how correctly organizational and technological tasks are solved; How measures are being carried out on quality control. And the main task of such monitoring is confirming the availability of qualified personnel for welding work.

It is important that the enterprise has documentation on technological processes that are used in the organization's production activities. It is a detailed instruction with a description of all stages of performing a wider cycle. As a rule, it is developed by profile specialists with higher education. The quality of study of the technical documentation sections is largely depends on the duration of the company's verification by SBS specialists. The shortcomings can extend the validity period and ultimately lead to a refusal to issue a certificate.

Specialists of the company's checked need to be carefully prepared for certification. Commissions Nax must be provided to the following documents:

  • technological cards of operations performed;
  • a valid contract with the control laboratory to selective product samples;
  • industrial instruction of the welder;
  • Certificates of Nax, issued by the Company's specialists;
  • A complete list of equipment and separately that CEX certification has been passed;
  • Quality certificates for consumables and welding equipment.

In the process of certification of the company, as a rule, the quality of welded joints performed by welders of this organization is checked. In this case, it is allowed to resort to different methods of quality control, including destructive. Welding equipment is subject to check. Subject to the requirements of the regulatory documentation, a corresponding certificate is issued. It is signed by all members of the Commission and is valid for four years.

Operated equipment and equipment are checked by technical parameters. They should be the same as they specified in the accompanying passport. Deviation of indicators for the worse is the basis for the Commission to refuse to admit the equipment to perform welding. In the same way, things are both consumables. Provided that electrodes or other consumables are manufactured by large batches, a certificate is issued for a period of three years. If the products are small, then the document is issued for a period of one year. Communicably checked complete set of equipment provided to verify.

During the inspection, all systems and mechanisms are checked: electronics, mechanics, pneumatics, hydraulics. Testing necessarily includes trial welding of two metal blanks. After that, the quality of the seam received is checked and appropriate conclusions are made.

Additional Information

In manufacturing plants there are employees who cannot be attracted to certification. These include:

  • partbooks;
  • specialists who are involved in work in the framework of a short-term employment contract (no more than two years);
  • Young professionals;
  • An employee adopted on the competition worked for less than one year;
  • A specialist who is currently undergoing training courses.

Unfortunately, not all the leaders of enterprises and organizations understand that the Nax certificate is tolerance to the fulfillment of welding and its availability of employees. Otherwise, the welder cannot fulfill its duties. This is illegal. Before the start of the certification, members of the Commission should make a tolerance - permission to verify and exam.

Not every welder is allowed to assemble responsible structures. And only those who have passed the certification of Nax. What is NACS - decipher such: the National Welding Control Agency. It is this organization that is engaged in the control of the qualifications of workers related to welding work. These are not only welders, but also engineers, and technologists. By the way, each employee has its own level, but about it is slightly lower. So, the welder (NACS certificate received) is considered the highest qualified, therefore, it can perform work in the most responsible sites.

sample decoding certificate

The agency is engaged not only by the licensing of welders, in its conduct of a fairly large amount of functions.

  • Development of regulatory documentation.
  • Methodical manuals.
  • Consultations about properly held welding events.
  • Developing technical policy in enterprises.
  • Formation of expert commissions.
  • But the main thing is a certification.

Levels of certified workers

There are four levels for which certification is made.

  • Level number 1 is a welder of Nax. That is, it is welcome to carry out welding of responsible structures.
  • Level number 2 is a master welder. This specialist can control the welding process and give instructions about properly conducted operations. Instructions can be oral or written.
  • Level 3 is a technologist. Mainly, technologists are controlled by all welding processes in enterprises.
  • Level number 4 - engineers. These are the heads of welding services that approve documentation regulating welding processes.

It should be noted that welding equipment and tools are taking place. That is, the Agency controls the quality of the used snap-in confirming the ability to weld the responsible structures.

Welders pass three types of certification:

  1. Primary.
  2. Repeated when the time is coming the time of study at the courses of Nax.
  3. Extraordinary. This can happen if doubts have doubts from a higher organization in the qualifications of the welder.

The goal of the NASK certification has two points: to check the readiness of the company that is engaged in welding, and confirmation of the qualifications of employees of the company admitted to the conduct of complex welding works.

How to get a certificate

Licensing employees is produced in special training centers that are in the Nax registry. In order to pass on the exam, the welder provides a package of documents, which except the application includes: a medical record, an extract from labor, confirming work experience, documents on education and special preparation, photographs, safety verification reports.

Rent 2 exams: theory and practice. If one of the exams is not commissioned, the welder can re-pass a test in a month. The first is the exam in practice, if he is not commissioned, then the welder is no longer allowed to pass theoretical knowledge. As for the certification of engineering composition, their knowledge is mainly checked for verification of standards and requirements in narrow directions on narrow specializations. Often, the issues of the Commission affect not one type of welding, but several. Therefore, it is recommended to know the engineers to know all types of welding, requirements for them and technical standards of the welding process.

Attention! If the welder or engineer did not work for half a year in his specialty, then it must complete the Tax exams.

Before the exam, it is recommended to explore the documentation for welding processes and standards that are developed in Nasc sidelines. Training in the courses of welders affects all positions that will be present in the exam tickets. Therefore, it is very important to attend such courses. The courses are required:

  • Safety technique during welding;
  • methods of control of welding seams;
  • Welding equipment and consumables;
  • Welding and soldering - technological processes;
  • Ways to eliminate the obtained defects.

In principle, all these sections the welder can explore both independently without visiting advanced training courses. Just at the same time, the certificate will not be issued on the hands, that the employee passed these courses. The main thing is to pass the certification of the Commission.


Welder Nax receives a certificate at the end of positive exams. Nax Certate - What is it? This is a confirmation that the worker can work on objects that are controlled by Rostechnadzor.

The certificate is issued to all specialists (all levels). At the same time, the Welder Nax passes re-certification in two years, the master and technologist through three, and the engineer in five years. At the same time, it is necessary to take into account the fact that in the certificate will be marked, to what types of welding work this employee is allowed.

For example, the "RD" mark suggests that the Welder Nax is allowed only for welding operations by manual arc welding. Rad - manual argon conversion welding with uncomplicated electrodes. G - gas. MP - mechanized. KTS - contact point welding. AF - automatic method under the flux. List is large for each position. Multiple marks are often set, which provide admission to several welding types. The received certificate is tolerance for welding of responsible structures.

Certification of enterprises and organizations

Companies that are engaged in welding processes should also pass attestation of NACs. Its goal is a confirmation that the company has all the possibilities (technical, technological and organizational) on the conduct of certified technology, which inside the production is carried out correctly. Of course, the presence of specialists confirmed by NACS, a prerequisite.

At the same time, a technological documentation should be present at the enterprise, which describes the welding technology technology used on the facility. In essence, this is a technological instruction, as well to carry out welding operations. It is usually developed by specialists with higher education. From how qualitatively a documentation was developed, the duration of certification of NACS will depend on. The shortcomings will only increase the check, which may ultimately lead to the failure of the certificate.

Therefore, it is recommended to prepare specialists of companies. What will be necessary for this will be provided by the Commission of the NACC.

  • Technological card of the welding process.
  • Instructions.
  • The contract that the laboratory of welding control conducts periodic checks.
  • Quality certificates for welding equipment and consumables.
  • List of equipment that has already passed the certification of Nax.
  • Certificates of Nax, confirming the qualifications of employees of the company.

In the process of checking a company for compliance with NACC standards, welded joints are usually examined. Here are used and destroying methods and non-destructive. Welding equipment is checked. If all the standards are observed, the certificate is issued. He is signed by the members of the Commission, indicating the name and position. Certificate is 4 years.

As for the equipment check, it is certified by technical specifications that must comply with indicators in the accompanying documents (passport). The deviation in the lower side gives the right to commission not to take it as possible in the conduct of welding operations. The same applies to consumables. If they are produced by serial parties, the certificate is issued for three years if small parties, then for one year. Must be checked completeness of technological equipment.

When testing, all systems are checked: electrical, pneumatic, hydraulic, mechanical. Typically, the check passes in the form of welding of the joint of two metals. Based on this and the assessment is given.

additional information

There is always a group of workers to the enterprise, which is not subject to certification. This list includes:

  • specialists working under an urgent contract for up to 2 years;
  • partbooks;
  • Welder Nax (master, technologist, engineer), which is in advanced training courses;
  • The completed contest worker who works for less than one year;
  • young specialist.

Not all enterprise leaders understand that the Tax Certification is tolerance. If there is no employee, it is impossible to allow him to conduct welding work or their control. This is illegal. Checking organizations when conducting certification must present their own tolerance, that is, permission to conduct inspections and exams.

Training welders Nax.

All employees of enterprises planning to associate their professional activities with the implementation of welding or surfacing work must necessarily pass attestation of NACS - the National Welding Control Agency. This applies to those who want to achieve professional growth in these works. This not only allows you to comply with the legislative requirements in this matter, but will also increase the practical and theoretical skills of workers.

The price for tuition begins from 95 tr. For timing - one month.

There are requirements for passing welders with the corresponding level of professionalism of certification. They are set forth in such legislative and regulatory documents of the Russian Federation, as law No. 1029618-6-FZ, the Resolution of Gosthernkhnadzor No. 63 of 30.10.98 and No. 101 of 19. 06. 06. This is also the leading documents and technical regulations, Regulating as the process of certification of welders and welding production.

In essence, certification is the process of passing a specialist of several exams confirming the compliance of its practical and theoretical preparation of the qualifications to which he claims. Accordingly, preliminary training is necessary to prepare for these exams. In addition, without providing a crust on passing preliminary training, admission to certification is not produced.

Who needs to be trained Nax?

Training takes place all welding workers applying for certification of NACS. In general, they are divided into 4 groups, in accordance with the level of qualifications.

Employees receiving 1 level are specialists who have experience in welding production at least 6 months and applying to the "Welder of Nax" level.

2 Levels are obtained by those employees who have the right to provide mandatory instructions to fulfill other employees. They get the "master welder" qualification.

The following 3 levels are obtained by specialists, whose duty is to develop, approval, control of technological welding processes. They are assigned the qualification "welder-technologist".

The latest category of specialists is the governing staff and engineers of welding production, on the signature of which the approval of the entire documentation required to perform surfacing and welding works is depends. Their qualifications are "Welder Engineer".

Where can I get trained welders of the NACS?

Training is conducted by specialized centers. Terms and cost of training are determined by the need for employee level of training. On average, the cost of learning is from 95,000 rubles, and the duration is a month.

After studying, all the training specialists receive a document of the established sample, which is a certificate or a crust on the end of the training, which in the future it will be necessary to attach to the package of documents necessary to submit an application for certification.

What advantages is learning?

The main task is to provide the level of knowledge that is necessary for the successful passage of certification of NACK employees. In addition, training is always accompanied by an increase in the skills of a specialist, expanding his skills and knowledge. The type of preparation under consideration will allow employees to receive and improve knowledge not only in the field of welding work, but also in matters of ensuring safety and labor protection during their implementation.

If the organization plans to conduct welding, especially in cases of dangerous or complex objects, the presence of certified professionals will become a clear advantage compared to competing organizations.

Properly organized training plays not the last role in the surrender of the necessary examinations and receiving certification. In case of insufficient training, the exams can give up employees again and again. This leads not only to temporary losses, but also significant financial costs, because each new exam requires a re-payment.
