Welder is a prestigious profession. They get paid better than many others, because a high-quality welder is worth his weight in gold. But knowing how to cook using conventional methods is not a difficult task. As practice shows, several attempts, and even the most ordinary person can somehow weld one metal piece to another. That’s why people learn this profession, that’s why there is such a thing as the ranks of welders.

So, welders are assigned six categories, which depend on the qualifications of the worker. To improve your qualifications means to receive the next rank. And this is not only honor and respect, it is a solid increase in wages. This is an opportunity to take part in more complex projects.

Before moving on to analyzing the categories of welders, it is necessary to understand the categories.

They depend on the ability to use one or another welding technology.

• Welders who work on resistance spot welding equipment. There are no electrodes, and the process itself is quite simple.
• Workers who can work on diffusion-welding type installations. These are operations with a piece connection, which allows you to increase the characteristics of the weld.
• Ability to work on electron beam installations. Welding is carried out in a vacuum; workpieces made of special alloys are usually joined using this technology. Such an employee must know a lot; he usually has the highest qualifications.
• A welder who can perform thermite welding. The process itself is carried out on special presses, the welding molds of which are heated, and therefore the parts being joined are heated.
• Gas welding. Such a worker is called a gas welder. By the way, he can also cut metals using a gas cutter.
• And the last category is electric welder. The most popular profession in the welding category.

Welding discharges

A welder of the first category is, in fact, a novice master, or rather, an apprentice. Such workers are not classified as qualified; they are still learning and can perform simple operations of cutting and welding non-critical structures. Such categories are assigned to students of vocational schools.

A welder of the second category is a graduate of welding courses or an educational institution who can perform welding in a lower and vertical position. But at the same time, such a specialist cannot seal pipelines during welding joints.

A 3rd category welder is also a graduate of a specialized educational institution. But he has no experience in manufacturing or construction.

• Firstly, a 3rd category welder must be able to weld corner, vertical and bottom seams, plus weld hermetically sealed pipe structures.
• Secondly, he must understand welding equipment, know the principles of its operation, as well as safety precautions when carrying out welding operations.
• Thirdly, he must be able to read blueprints, because this was taught to him during his studies. And assemble structures according to the drawings. But only simple products are trusted to him.

A 4th grade welder can work with structures and parts of average complexity. This is already a qualified specialist who can carry out welding in any position except the ceiling. In addition, he has the skills to create sealed seams when welding two pipes that will operate under pressure. Knowledge of drawings and other skills is required. A 4th grade welder earns more than all previous workers.

Welder 5th category. This category is assigned to those craftsmen who can weld in any position and cut any configuration from sheet material. At the same time, the fifth category indicates that its owner is allowed to weld any types of pipelines. At the same time, it can weld workpieces of any thickness, any grade of metal and its alloys.

Welder 6th category. This is the highest level. Its owner performs all operations, like the owner of the previous rank. But only he is trusted to carry out welding work related to joining workpieces from experimental alloys that no one has ever welded before. It is the sixth high that gives him the right to determine for himself how to cook, in what mode and with what consumables (electrodes, additives, gases, and so on).

How to increase the rank of a welder

For example, a 3rd category welder wants to upgrade his category to the fourth. What needs to be done for this. If he works in a large enterprise, then it must have a qualification commission. You need to contact it, after which the exam day will be set. You must pass this exam and receive a document that will confirm that you have received an increased rank.

If the enterprise is small, you will have to contact training center, where welders undergo advanced training. But it is necessary to clarify whether you will receive a document for the next grade, or you will only be given a certificate stating that you have attended a certain course. If this is the second option, then this does not bode well for you, because the certificate is only confirmation that you were just studying. Therefore, it is worth looking for a training center that will assign qualifications and issue the necessary document. It will need to be provided to the head of the enterprise, the human resources department and the accounting department. This will serve as proof that the employee can receive a salary increase and be involved in work with increased complexity. And a 4th grade welder gets more than a 3rd grade welder.

Advantages and disadvantages of the profession

The advantages include:

• Constant demand in the labor market.
• High salaries.

On the downside:

• Very often you have to work in difficult conditions, one might even say extreme.
• Eye strain even with protective glasses and masks.
• The welder constantly inhales industrial dust, so their occupational diseases are silicosis, asthma, pneumoconiosis.

And yet the profession of a welder is very popular. Of course, salary plays a big role. But there will always be work for them, so young specialists who have graduated educational institutions welder by profession, they quickly find work. Many industries give quotas for their hiring, regardless of qualifications, because many progressive managers prefer to grow workers for themselves rather than hire them on the side, fulfilling the workers’ conditions.

For development industrial production V modern Russia The need for highly qualified specialists in blue-collar professions has increased sharply. One of these professions is the profession of a welder. Thus, an analysis of the labor vacancy market showed that today more than 21,000 jobs across the country are waiting for welding specialists.

What skills does a welder need to have to get this job? What are the characteristics and working conditions of this category of workers? How do they affect people's health? How much does a welder earn per month? Does he have the opportunity to increase his income?

Range of professional responsibilities of a welder

Many modern structures are based on many metal elements. In order for the structure to hold firmly, specialist welders are needed who will carry out the work of connecting its elements into a single whole. If the work is done efficiently, the structure will last a long time and its operation will be reliable and safe for humans.

If the welding of parts is carried out with poor quality violations, then sad consequences cannot be avoided. Under the influence of load, welding seams can separate, and after this the entire structure will collapse, which will inevitably lead to the destruction of the object and even the death of people. Therefore, every welder must treat his work with a high degree of responsibility. He must constantly improve his skills and achieve high quality welding work.

Welding structures is a complex and creative process at the same time. There are three main types of welding:

• automatic electric welding;
• electric arc;
• gas welding;

Not all workers with a diploma in the specialty “Welder” can be admitted to all of the listed types of welding work. To work with each type of welding, you must have the appropriate specialization.

In order to master the skills of working on all types of welding equipment, it is necessary to master a significant amount of special knowledge. Among them, knowledge of the rules for the safe use of welding equipment, the basic principles of operation of the equipment and the ability to use technical means. The welder must have a good knowledge of the properties of metals and alloys and the peculiarities of changes in their properties under the influence of high temperatures.

In addition, a true welding professional must love his job, be responsible for all production tasks, be resilient and have good physical health.

What does the salary depend on?

The salary of a welder is determined by the following factors:

Welder rank and work experience

The level of professionalism of a welder is determined by his rank, which means that the higher the rank, the higher the specialist’s salary. There are six categories of welders.

2. A 2nd category specialist can perform simple welding work on minor parts and receives 15-20 thousand rubles for his work. monthly.
3. The 3rd category gives access to work on the main sections of metal structures and pipelines, and provides an income of 20-30 thousand rubles.
4. A 4th grade welder does basic welding with seam cutting for 30-40 thousand rubles. per month.
5. A 5th category professional is allowed to work on important areas of complex technological structures, including pipes under high pressure. Such work brings in up to 40-50 thousand rubles per month.
6. The highest 6th category provides the ability to work on the most complex and critical objects oil and gas industry, shipbuilding, aircraft and rocket engineering. Generalist welders earn more than 50 thousand rubles per month.

Place of residence and place of work

The salaries of welding specialists living in the Far North, Far East, as well as in the Moscow region significantly exceed the earnings of welders in other territories of the country.

Employees of oil and gas complex enterprises receive the highest salaries - up to 200 thousand rubles. And for welders who ensure the work of housing and communal services, monthly incomes amount to 20-45 thousand rubles. It is worth noting that welders working in hazardous industries earn more than their colleagues. Yes, welders argon welding on average they receive 60-65 thousand rubles per month.

Shift work method

Today, the labor market offers welders from the central regions of Russia up to 50% of open vacancies with employment in the Orenburg and Tyumen regions, the Yamalo-Nenets Autonomous Okrug, and the Krasnoyarsk Territory. Employers are willing to pay 100-150 thousand rubles. per month.

Additional bonuses

As an additional bonus, organizations inviting welders to work on a rotational basis, pay employees for accommodation, food, travel to and from work.

Besides, harmful conditions welders' labor assumes an annual additional leave lasting at least 7 days. Some types of work, incl. outdoors means an increase in vacation by 12 days.

Average salaries of Russian welders

The average monthly salary of welding specialists in Russia is 47-49 thousand rubles, which is approximately 1.5 times higher than the average salary in the country’s economy.

In Moscow

In the Moscow region, welders earn between 30-200 thousand rubles per month. Average earnings are 60-70 thousand rubles. This corresponds to the average salary indicators for the Moscow economy. Today, the demand in the labor market in the capital for welding specialists is great; about 1,200 vacancies remain open. Employers undertake to pay workers in this profession 30-130 thousand rubles.

In the regions of Russia

Welders earn the highest wages Tyumen region and Yamal-Nenets Autonomous Okrug, they receive 110-120 thousand rubles monthly for their work. Average salary welders in St. Petersburg, Volgograd corresponds to the average monthly income of this category of Russian workers - 48-50 thousand rubles. IN Yekaterinburg, Novosibirsk, Krasnoyarsk, Omsk, Perm, Samara, Ufa and Chelyabinsk average salaries are at the level of 33-40 thousand rubles.
