Welding is a prestigious profession. They get better than many, because a high-class welder is worth its weight in gold. But to be able to cook in the usual ways is a simple matter. As practice shows, several attempts, and even the most ordinary person can somehow weld one metal blank to another. That is why people study this profession, that is 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 qualifications means to get the next level. And this is not only honor and respect, this is a solid increase in wages. This is an opportunity to take part in more complex projects.
Before proceeding to the analysis of the categories of welders, it is necessary to understand the categories.
They depend on the ability to use a particular welding technology.
- Welders who work on 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, usually blanks made of special alloys are joined by 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 to be joined are heated.
- Gas welding. Such an employee is called a gas welder. By the way, he can also cut metals using a gas cutter.
- And the last category is the electric welder. The most demanded profession in the category of welding.
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 for cutting and welding non-critical structures. Such categories are assigned to students of vocational schools.
A welder of the second category is a person who has completed a welding course or an educational institution, who can perform welding in a lower and vertical position. But at the same time, such a specialist cannot carry out sealing of pipelines during a welding joint.
The welder of the 3rd category 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 fillet, vertical and bottom seams, plus weld hermetically pipe structures.
- Secondly, he must understand the welding equipment, know the principles of its operation, as well as safety precautions during welding operations.
- Thirdly, he must be able to read drawings, because during his studies he was taught this. And assemble structures according to the drawings. But only simple products trust him.
A 4th category welder can work with structures and parts of an average complexity category. This is already a qualified specialist who can weld in any position, except for the ceiling. In addition, he has the skills to create sealed seams when welding two pipes that will work under pressure. Knowledge of drawings and other skills is required. A rank 4 welder receives the most of all previous workers.
Welder of the 5th category. This category is assigned to those craftsmen who can weld in any position and cut out any configuration from sheet material. At the same time, the fifth category indicates that its owner is allowed to weld any type of pipeline. At the same time, it can cook workpieces of any thickness, any grade of metal and its alloys.
Welder of the 6th category. This is the highest grade. Its owner performs all operations, like the owner of the previous category. But only he is trusted to carry out welding work related to the connection of workpieces from experimental alloys, which no one has ever welded. 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, etc.).
How to increase the rank of a welder
For example, a 3rd grade welder wants to upgrade his category to 4th. What do I need to do. If he works at a large enterprise, then he must necessarily have a qualification commission. You must contact it, after which the day of the exam will be set. You must pass this exam and receive a document that will confirm that an increased level has been received.
If the enterprise is small, then you will have to contact a training center where welders undergo advanced training. But it is necessary to clarify whether you will receive a document for the next category, or you will only be given a certificate stating that you have taken a course. If this is the second option, then this does not bode well for you, because the certificate is only confirmation that you just studied. Therefore, it is worth looking for the training center that will assign qualifications and issue the necessary document for this. It will need to be submitted to the head of the enterprise, to the personnel department and to the accounting department. This will serve as proof that the employee can be raised in salary and involved in work with increased complexity. And a 4-grade welder gets more than a 3-grade welder.
Advantages and disadvantages of the profession
The advantages include:
- Constant demand in the labor market.
- High salaries.
By cons:
- Very often you have to work in difficult conditions, one might even say extreme.
- Eye strain even with goggles and masks.
- The welder constantly inhales production dust, so their Occupational Illness 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 professionals who have graduated educational establishments as a welder, they quickly find a job. Many industries give quotas for their admission, regardless of qualifications, because many progressive leaders prefer to grow workers for themselves than to hire on the side, fulfilling the conditions of workers.
