Qualification characteristic of a welder of the 2nd category. Qualification characteristics. What should I know

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 a 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 qualification categories (1-6), showing the level of proficiency in welding equipment and professionalism in performing work. The 2nd grade 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 the 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 and cutting, the 2nd class 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 of the necessary knowledge and skills that a level 2 welder must have.

Welder's salary 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 welders - trainees 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 category.

Most welders try to get higher and generally accepted grades as soon 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. A 2nd class 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 for improvement 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.
