Details

As in every profession, the profession of a 2nd grade welder or any other has its pros and cons. The advantages of this specialty include prestige and high demand among employers. Newbie welders who have recently graduated from an educational institution do not have to look for work for a long time.

Welders who do not yet have work experience are most often hired by housing and communal companies or private organizations. After a certain time of constant work, "fouling" experience and skills, after raising qualifications or category, the welder can go to work in industry or construction.

The disadvantages of the specialty are difficult working conditions, work in all weather conditions in open places, in the strong influence of ultraviolet radiation, infrared radiation from welding on the welder's eyes, as well as a large emission of gases when working with welding.

What should a grade 2 welder be able to do?

Welders, like all working professions, have their own qualifying ranks(1-6), showing the level of proficiency in welding equipment and professionalism of the work. The 2nd category of a welder is also considered an initial (student), like the first, but with a more responsible approach to duties and greater confidence in the welding work performed.

A 2nd class welder should be able to:

Perform manual electrode and plasma welding works to weld the lightest and most primitive metal parts and systems in the lower, vertical position of the weld.
To make surfacing of elementary uncomplicated units.
Preheat workpieces and products before starting welding.
Carry out tacking of workpieces, products and metal structures in all spatial positions of the weld.

Also, a 2nd grade welder must know:

The mechanism of operation of electric welding equipment for electrode welding with alternating and direct current.
How to properly maintain electric welding machines.
The sequence of material preparation for welded work.
Various chopping options.
Basic characteristics of the used electrodes, processed material and alloys.
Purpose and circumstances of use of the used measuring devices.
Where do defects come from during work and how to prevent them?
Basic knowledge of inert gas welding.

In simpler terms, a Level 2 welder should be able to cut any metal using a variety of hand torches from any power source, from electricity to kerosene.

Of course, he must have the skills to weld various metal products with any manual welding. A welder of the 2nd category must be able to lead the weld not only in a straight line, but also curvilinearly, and be able to do all this, both in the lower vertical position and in other spatial positions.

After welding works and cutting, the 2nd category welder is obliged to clean the seams. Also, at this level, a specialist should already understand the drawings and be able to properly prepare gas cylinders for work. And this is a far from complete list. necessary knowledge and the skills that a level 2 welder must have.

Salary of a welder of the 2nd category

As you already know, each category of a welder has its own wages. The higher the rank, the higher the payment. The 2nd category of the welder, like the first, is not common. Basically, the first two categories are considered student and they are assigned, in most cases, to trainee welders studying in specialized educational institutions or a person who graduated from training courses for the specialty of a welder and passed certification for this particular category. There are even cases when a 3-grade welder is lowered to grade 2 due to the inconsistency of his work with this grade.

Most welders try to get higher and generally accepted grades as quickly as possible, such as the 3rd, 4th and 5th grades, since they are more in demand in production and industry, and the salary is higher.

Speaking of salary. The 2nd grade welder earns relatively little, if not little. Like the first-rate, the second-rate salary can be piecework or at a rate. But in either case, such a welder currently earns, depending on the region and place of work, an average of 12-15 thousand rubles.

Of course, it is not worth stopping at this, because the specialty of a welder is multidisciplinary, and there is room to grow in it. There would be a desire, and everything else will be. The welder of the second level earns little, then you need to increase your rank. To do this, it is worth taking courses to improve the qualifications of welders, where you can not only enrich your knowledge, but also raise your professionalism and hone your skills. Plus, a new category will be added to this, which will allow you to earn more.

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

What skills does a welder need to have to get this job? What are the features 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?

The scope of professional duties of a welder

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

If the welding of parts is made with violations of poor quality, then the sad consequences cannot be avoided. Under the action of the load, the welding seams can disperse, and after that the entire structure will collapse, which will inevitably lead to the destruction of the object and even to the death of people. Therefore, every welder should 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 welding works. 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 of safe use of welding equipment, the basic principles of equipment operation and the ability to use technical means... The welder must know well the properties of metals and alloys and the peculiarities of changing their properties under the influence of high temperatures.

In addition, a true welding professional must love his job, treat all production tasks responsibly, be enduring and have good physical health.

What determines the size of the salary

The welder's salary is determined by the following factors:

Welder rank and work experience

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

1st category allows you to carry out only auxiliary work, which will bring no more than 10-12 thousand rubles. per month.
A specialist of the 2nd category can perform simple welding of non-main parts and receives 15-20 thousand rubles for his work. monthly.
Grade 3 gives permission to work on the main sections of metal structures and pipelines, and provides income in the amount of 20-30 thousand rubles.
The 4th grade welder is engaged in basic welding with cutting seams for 30-40 thousand rubles. per month.
A 5th grade professional is allowed to work in important areas of complex technological structures, including pipes under high pressure. Such work brings up to 40-50 thousand rubles a month.
The highest 6th grade provides the ability to work on the most complex and critical facilities in the oil and gas industry, shipbuilding, aircraft and rocketry. Universal welders earn more than 50 thousand rubles a month.

Place of residence and place of work

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

The highest wages are received by employees of oil and gas enterprises - up to 200 thousand rubles. And welders providing the work of housing and communal services have monthly incomes of 20-45 thousand rubles. It should be noted that welders working in hazardous industries earn more than their colleagues. Thus, argon welders receive an average of 60-65 thousand rubles per month.

Rotational work method

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

Additional bonuses

As additional bonuses, organizations that invite welders to work on a rotational basis, pay employees for accommodation, meals, travel to the place of work and back.

In addition, hazardous working conditions for welders require 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 in the range of 30-200 thousand rubles per month. Average earnings are 60-70 thousand rubles. This is in line with the average salaries in the Moscow economy. Today, the demand for welding specialists on the labor market in the capital is great, about 1200 vacancies remain open.
