A mechanical assembly mechanic is a specialist who has certain knowledge in the field of production of parts and assembly of mechanisms. He must have certain personal and professional qualities that will ensure the maximum quality of the product he makes.

What knowledge should the represented specialist have?

So, now let’s figure out what a mechanical assembly mechanic should know:

What actions should a professional perform? What kind of discharge grid does this specialist have?

A mechanical assembly mechanic performs threading on parts, welding and riveting work, and preparation of various workpieces from metal rods. The activities of the presented specialist are related to grinding, drilling, milling and other machines. In addition to welding, in his work he uses cold and hot soldering, glue, as well as some other types of fastening parts. This specialist can also install unique pipelines. In addition, he can perform many other works related to fitting, manufacturing and assembling parts into a single mechanism.

As for the level of qualifications, it depends on where the specialist received his education and what practical skills the mechanical assembly mechanic has. The ranks are determined by the complexity of the operations that it performs. receives by decision of a special commission. The tariff schedule includes 5 categories (from 2nd to 6th). Each of them involves its own list of works.

What responsibilities does the specialist have?

Basically, they consist of what the represented professional does. That is, he must not only be able to completely assemble various mechanisms (stands, machines, vehicles), but also know how to properly manufacture and process the necessary parts. He must be able to work with metals and other materials with which they are connected.

A mechanical assembly mechanic, whose duties include knowledge of safety rules when working on various machines, must be able to make certain calculations and draw diagrams of parts. He also tests and eliminates flaws in the assembled mechanisms.

Mechanical assembly mechanic is a difficult profession, and not everyone is able to master it. The reason lies in the fact that future specialists will have to study the structure of many mechanisms, and this requires an innate talent for memorization. In addition, a mechanical assembly mechanic must have excellent endurance and strength, because the specifics of the work will repeatedly force him to deal with heavy parts and mechanisms.

And yet, anyone who masters this specialty can be sure that he will have decent job. After all, mechanics are always needed in enterprises, especially highly specialized ones.

What is a fitter?

This branch of specialists is engaged in the assembly of mechanisms and devices. In particular, they install various types of turbines, motors, nozzles, heating units, and so on. If we compare an ordinary mechanic with his mechanical assembly colleague, the second differs in that he has more in-depth knowledge in the field of mechanics.

If in ordinary enterprises there is no particular need for such specialists, since their duties can be performed by an ordinary mechanic, then in factories producing various equipment they are simply irreplaceable. Especially where they create high-tech mechanisms and assemblies that require increased attention during manufacturing.

How to become a mechanical assembly mechanic?

You can obtain a locksmith qualification at a technical school or college. Upon admission, you will need to pass an exam in physics and mathematics. They cannot be called 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 mechanic. Journeyman duties exclude operations increased complexity, so you shouldn’t count on full payment. But still, given that this is only a step on the path to the desired profession, such a budget distribution can be tolerated.

Finding a suitable job

Finding a job as a mechanic will not be difficult, because they are necessary in any enterprise. Remuneration will depend on the size of the organization and the responsibilities that will fall on the shoulders of the mechanic.

As for searching for vacancies in the specialty "mechanical assembly mechanic", everything is more complicated here. After all, in small enterprises there is no need to divide mechanics into categories, and no one will pay extra for highly specialized education.

Therefore, it would be wiser to look for work in large enterprises. The modernization of machinery and equipment is constantly carried out here, which means that the services of a fitter will be relevant. Also, do not forget about factories that produce machines, 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, an automation control mechanic or a tool maker.

What are the responsibilities of a mechanical assembly mechanic?

A lot in future profession depends on the specific production chosen. After all, it’s one thing when a person works at a car plant, and quite another thing in the metal rolling industry. Nevertheless, it is possible to draw certain parallels.

A mechanical assembly mechanic has the following responsibilities:

1. First of all, a mechanic must be able to work with various mechanisms: assemble them based on drawings, adjust parts, configure and check for suitability.
2. The responsibilities of a locksmith also include repairs. Firstly, he is responsible for the serviceability of the products he produces. Secondly, he is obliged to repair all the mechanisms on his site in order to prevent downtime in production.
3. Regardless of the type of production, he must report to higher management.

Job description for mechanical assembly mechanic

When starting a job, each mechanic must sign a number of documents. Among them there are instructions for a mechanic for mechanical assembly work. It specifies all the duties and rights of this worker.

The job description of a mechanical assembly mechanic is a set of rules, and violating them is strictly prohibited. In general, such a document can be divided into four large sections.

1. Basic provisions. Here are the requirements for the future employee: list necessary documents, his position in production, at whose disposal he will be, and so on.
2. Tasks and responsibilities. A list of all operations that a specialist will have to perform at the specified production site.
3. Rights. A list of what a mechanic is supposed to do: length of the working day, availability of lunch, and the like.
4. Responsibility. This paragraph identifies all situations that could lead to financial punishment.

Mechanical assembly mechanic: categories

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 category of at least 5.

Naturally, the higher the rank, the greater the chances of finding a high-paying job. And yet, a mechanical assembly mechanic is a profession where experience is valued above all, not a diploma. Consequently, there is a high probability that you will have to work in a small enterprise for the first 2-3 years and only then apply for more promising vacancies.
