5 main misconceptions about professional standards.
Currently, the qualification requirements for the position of a repairman are approved by the Decree of the Ministry of Labor of the Russian Federation of November 15, 1999 No. 45. qualification requirements established criteria for the level of education, only for repairmen of the 7th and 8th category. Requirements for work experience are not provided for any categories of repairmen. At the same time, for mechanics-repairmen of the 7th and 8th category, a requirement is established for the presence of secondary vocational education, without presenting requirements for the direction of education.
For the remaining categories of repairmen, only the requirements for the worker in relation to special knowledge, as well as knowledge of the provisions, instructions and other guidance materials, methods and means that the worker must apply, are provided. In addition, a list of works is established that is most typical for a given profession, which a worker can and should perform ( see attachment to answer below).
It should be noted that the legislation does not oblige the employer in any way to check the availability of relevant knowledge and skills of the employee. Therefore, the employer has the right to accept the profession of a repairman from the 2nd to the 6th category of a person without work experience and relevant education, if he considers that he has the necessary knowledge and skills.

Activity content: Mechanical fitter assembly work- basic actor while creating finished product. He assembles machines and mechanisms from parts received from other workshops of the enterprise or from other enterprises. To assemble a finished mechanism, you must first study the drawing, prepare the parts, then assemble the individual units, adjust, that is, check the correct interaction of the assembled parts and units, and, finally, test the assembled product. Sometimes the preparation of parts requires adjusting their dimensions to the required ones. The fitter-assembler has to carry out fine-tuning of parts with the help of special locksmith tools. Fitting parts requires knowledge of the properties of metals and alloys, as well as knowledge of all types of locksmith work related to the processing of a part. The connection of parts into units and later in the structure occurs by pressing, soldering, welding, as well as using bolts, dowels, threads, rivets and other fastening methods, depending on the mechanism being assembled. For example, when assembling a ship's hull, a mechanic needs to use hammers of various calibers, welding tools, and when assembling a radio circuit, screwdrivers, a soldering iron, and files. In most industries, a significant part of the assembly work is done automatically. High-level locksmiths make static and dynamic adjustment of complex parts and assemblies, calculate gear couplings, identify and eliminate assembly defects, and participate in the preparation of a passport for assembled and tested products.
Dominant interests: Engineering, metalworking. Test "Drawing-everything with the letter Sh"
Related interests: Mathematics, physics, chemistry.
Test on the course "Metalworking"
Communication at work: assembly fitters often work in teams and have the help of specialists from other profiles. Therefore, they need the ability to work in a team, a developed sense of responsibility not only for their area of work, but also for the work of the entire team as a whole.

Mechanical assembly fitter: features of the profession
A mechanical assembly fitter is a specialist who has certain knowledge in the field of manufacturing parts and assembling mechanisms. He must have certain personality and professional qualities that will ensure the highest quality of the product made by him.
What knowledge should the presented specialist have?
So, now let's figure out what a mechanical assembly fitter should know:
- conditions and rules for assembling mechanisms, their structure and functionality;
- mechanical and Chemical properties the materials with which he works;
- the result of the influence of various conditions on metals (heating, melting, welding, cooling);
- system of landings and tolerances;
- features of the use and sharpening of tools;
- rules for making welded and riveted seams, as well as features for ensuring maximum joint strength;
- a method of marking various kinds of parts;
- the use and features of the use of various solders, fluxes, pastes and mordants;
- the functionality of various measuring instruments that may be useful in the work.
What steps should a professional take? What grid of discharges does this specialist have?
A mechanical assembly fitter does not only assemble products, but also adjusts the dimensions of parts. After connecting them into a single structure, he must check the quality of work and the strength of the product. If there are any defects in the mechanism, this specialist eliminates them. As for the structures with which the locksmith interacts, these are: machine tools, cars, complex and unique units, industrial equipment.
A mechanical assembly fitter performs threading on parts, welding and riveting, preparation of various blanks from sheet steel and metal rods. The activity of the represented specialist is connected with grinding, drilling, milling and other machines. In addition to welding, he uses cold and hot soldering, glue, and some other types of fastening parts in his work. This specialist can also install pipelines, unique test benches. In addition, he can perform many other work related to fitting, manufacturing and assembling parts into a single mechanism.
As for the level of qualification, it depends on where the specialist received his education and what practical skills the mechanic of mechanical assembly works has. The ranks are determined by the complexity of the operations that it performs. A specialist receives a qualification by decision of a special commission. The tariff scale includes 5 categories (from the 2nd to the 6th). Each of them has its own list of tasks.
What are the responsibilities of a specialist?
In principle, they are what the presented professional does. That is, he must not only be able to fully assemble various mechanisms (stands, machine tools, vehicles), but also know how to properly manufacture and process necessary details. He must be able to work with metals and other materials with which they are connected.
A mechanical assembly fitter, whose duties include knowledge of safety regulations when working on various machines, must be able to make certain calculations, draw diagrams of parts. He also conducts testing and elimination of flaws in the assembled mechanisms.
Job description for a mechanical assembly worker - a document designed to describe the rights, duties and required skill level of an employee holding this position. Let's figure out why such a document is needed and how it is compiled.
Why do you need a job description for a locksmith?
Unlike employment contracts job descriptions are not among the documents that must be drawn up for each employee. They do not replace the professional standards that are gradually being introduced for various positions. Why, then, are they needed in enterprises?
How to become a mechanical assembly worker?
You can get a locksmith qualification at a technical school or college. Upon admission, you will need to pass an exam in physics and mathematics. You can’t call them simple, so you should prepare in advance, and if necessary, hire a tutor.
Another way is to get a job as an apprentice to an experienced specialist. After several years of such training, you will become a real mechanical assembly fitter. The duties of an apprentice exclude operations of increased complexity, so you should not count on full payment. But still, given that this is only a step on the way to the desired profession, such a distribution of the budget can be tolerated.
Finding the Right Job
Finding a job as a locksmith won't amount to special work because they are necessary for any enterprise. Remuneration will depend on the size of the organization and the responsibilities that will fall on the shoulders of the locksmith.
As for the search for vacancies in the specialty "mechanic of mechanical assembly works", everything is more complicated here. Indeed, at small enterprises there is no need to separate locksmiths into categories, and no one will pay extra for highly specialized education.
Therefore, it would be wiser to look for work in large enterprises. Modernization of machinery and equipment is constantly carried out here, which means that the services of an assembly fitter will be relevant. Also, do not forget about the factories that manufacture machine tools, various kinds of tools, units, and so on.
If there is nothing suitable, then you can get a job with a related specialization. For example, a mechanic for control of automation or a toolmaker.
What are the responsibilities of a mechanical fitter?
Plenty in future profession depends on the specific production. After all, it is one thing when a person works at a car factory, and a completely different thing is the metal-rolling industry. Nevertheless, it is possible to draw certain parallels.
The responsibilities of a mechanical assembly fitter are as follows:
- First of all, a locksmith must be able to work with various mechanisms: assemble them on the basis of drawings, fit parts, adjust and check for suitability.
- Also, the duties of a locksmith include repairs. First, he is responsible for the serviceability of his products. Secondly, he is obliged to repair all the mechanisms in his area in order to prevent downtime in production.
- Regardless of the type of production, he must obey the higher management.
Job description for a mechanical assembly worker
When applying for a job, each locksmith must sign a number of documents. Among them there is also an instruction of a mechanic for mechanical assembly works. It just specifies all the duties and rights of this worker.
The job description of a mechanical assembly fitter is a set of rules, and it is strictly forbidden to violate them. In general, such a document can be divided into four large sections.
- Basic provisions. Here the requirements for the poor worker are indicated: list required documents, his position in production, at whose disposal he will be, and so on.
- Tasks and responsibilities. A list of all the operations that a specialist in the specified production will have to perform.
- Rights. A list of what a locksmith is supposed to do: the length of the working day, the availability of lunch, and the like.
- A responsibility. In this paragraph, all situations that can lead to financial punishment are indicated.
Mechanical assembly fitter: ranks
There are 5 tariff categories. The youngest is the second, the oldest is the sixth. To be admitted to work of increased complexity, you must have a grade of at least 5th.
Naturally, the higher the rank, the more chances to find high paying job. Nevertheless, a mechanical assembly fitter is a profession where experience is valued first of all, and not a diploma. Therefore, it is highly likely that the first 2-3 years will have to work in a small enterprise and only then apply for more promising vacancies.
Job description for a locksmith of mechanical assembly works of the 4th category
"____" ____________ 20__
Locksmith of mechanical assembly works of the 4th category
1.1. Real job description defines functional responsibilities, rights and responsibility of a mechanical assembly fitter of the 4th category [Name of organization in the genitive case] (hereinafter referred to as the Company).
At the mere mention of the word "locksmith", a person appears in the mind who performs mainly mechanical work. In his hands you can see a screwdriver, a file, a wrench and even a sledgehammer. All these tools are brought to use by the instrumentation and automation fitter, since the equipment that has to be repaired, adjusted and maintained is very diverse.
Here you can meet the thinnest, almost clockwork mechanisms, heating furnaces, water valves, injection mechanisms of large injection molding machines or frequency-controlled electric drives. Therefore, the most diverse tools are required: from microscopic watch screwdrivers to pipe wrenches of the latest number.
When conducting various communication lines, for example, to connect sensors, a sledgehammer, and even scrap, is often used. Without this tool, it is absolutely impossible to make a hole in a brick, especially a concrete wall. True, recently these prehistoric tools have been replaced by modern electrified perforators, "grinders" and other tools. But, nevertheless, sometimes you have to use both a crowbar and a sledgehammer.
It often happens that in the mechanism some part made of sheet metal. To restore this part, you need to replace it, but if there is no spare, then, if possible, make a new one. It is enough for this to pick up a hammer, a chisel, a file, maybe even a drill with a drill and whip up at least a temporary replacement, for which, at least by hand with a pencil, sketch out a sketch of the future part. If an instrumentation mechanic has such skills, then he simply has no price!
The ability to work with hammers and screwdrivers is not all that one should be able to real instrumentation mechanic. First of all, he must know the basic laws of electrical engineering and have an electrical safety group of at least III, know how a transistor works, logical or. Knowledge of microcontroller technology will also come in handy, and if you have programming skills for microcontrollers, then this is very good, even excellent.
