Profession Electric and gas welder. Who is an Electric Gas Welder?
In the old days, metal products were jointed or monolithic. Today, there are several ways to connect metal parts so tightly that they become one. These methods include gas and electric welding. A person who masters both of these techniques is called an electric gas welder.
It's a kind of magic: joining two pieces of metal together. This specialty is very useful in construction and industry. The essence of welding (it makes no difference whether gas or electric arc) is that molten metal is poured between the edges of the parts to be welded, which are previously well heated.
The welder heats the edges of the parts being welded exactly as much as necessary. The thickness and quality of electrodes or wire used in gas welding must also be selected according to the metal being welded.
An electric gas welder performs work on welding and cutting metal parts of various configurations and cutting blanks of various shapes and holes of various sizes and shapes from sheet metal. He prepares the parts to be joined for welding and cleans the weld seams after it, welds horizontal, vertical and ceiling seams, welds cavities and cracks on parts, and performs metal cutting on semi-automatic and automatic machines.
One only has to look at how many welded metal products there are around us to understand how important these professionals are to society. Metal structures are most often welded using electric arc or gas welding. It is one of the most respected engineering specialties. If their work were removed from the places where it is now located, our world would fall apart at the seams.
Personal qualities
An electric gas welder must not be prone to allergic diseases, have a strong hand to hold the torch or electrode evenly, be careful and never drink alcohol at work.
average salary
From 35,000 to 60,000 rubles per month, depending on experience and place of work.
The salary consists of a salary and a bonus for the volume of processing.

Reference
An electric gas welder is a specialist who welds various metal products (metal structure components, pipelines, machine parts and mechanisms, etc.). According to one version, the word “welding” comes from the name of the ancient Slavic god of blacksmithing, Svarog. To weld metal, either gas or current is used. It turns out that this profession includes two others - electric manual welder and gas welder. People of this profession work in construction, mechanical engineering, metalworking enterprises, utility organizations, agriculture and many other industries.

How users rated this criterion:The life of any modern person is inextricably linked with the use of metal: without it it is impossible to build a house or a ship, make a castle or a computer, install electricity into the house or install bars on the windows. Metal surrounds us everywhere: in everyday life, construction, agriculture, industry. Therefore, it is not surprising that such a specialist as a gas-electric welder will be in demand, if not always, then for a very, very long time.
The life of any modern person is inextricably linked with the use of metal: without it it is impossible to build a house, plane, car or ship, make a gate, lock or computer, install electricity into the house or install bars on the windows. Metal surrounds us everywhere: in everyday life, construction, agriculture, industry. Of course, individual metal parts are of little use; in order for a metal product to become useful, all its parts need to be connected (welded) together. Therefore, it is not surprising that such a specialist as gas-electric welder will be in demand, if not always, then for a very, very long time.
It is not difficult to guess that the integrity, durability, uninterrupted operation and required technical characteristics of any metal equipment, product or structure entirely depend on the quality of the welding performed. From which it follows that the profession of a gas welder is not only in demand, but also very responsible: sometimes the safety of our home or the pleasure of using the benefits of civilization depends on it. In other words, you need to choose this profession for yourself consciously, after carefully studying all its features. And under no circumstances should you go to study to become a gas-electric welder (and then work in your specialty) just because you couldn’t get anywhere else.
Who is a gas-electric welder?
Gas-electric welder (electric-gas welder) is a qualified specialist who welds (connects) various metal products or structures using electricity or gas. This profession combines three related specialties: gas welder, manual electric welder, and welding machine operator.
Official "birthday" gas-electric welder profession It is generally accepted that the year 1802 was when the Russian scientist Vasily Petrov discovered the effect of the electric arc. Until this time, metal parts were connected to each other exclusively using forge welding. By the way, there is a version that the method of joining metal by welding got its name from the ancient Slavic blacksmith god Svarog (hence the name “welding”).
The main distinguishing feature of modern gas-electric welders from forge welders is the mobility of the former. If earlier, in order to weld a metal product, you had to go to a forge, order the production of parts and their connection from a craftsman, and then take the finished product home yourself, today you just need to call a gas-electric welder to the place where the metal parts are located, and he will do it right away will cook.
The main task of a gas-electric welder is both connecting metal parts and cutting metal products using a welding machine. In addition, he carries out adjustments and installation of the required mode on the welding machine, monitoring the welding mode, eliminating defects in metal parts and cleaning the seams after completion of welding work. In his work, a gas-electric welder uses a gas welding torch, electrodes, tongs, hoses, automatic and semi-automatic welding machines.
What personal qualities should a gas-electric welder have?
Since any error or negligence in work of a gas-electric welder can lead to catastrophic consequences (it’s scary to even imagine the consequences of the negligent work of a gas-electric welder who was involved in the construction of a multi-storey residential building), such a specialist must necessarily have the following personal qualities:
- attentiveness;
- responsibility;
- discipline;
- pedantry;
- patience;
- accuracy;
- mental stability.
In addition, a gas-electric welder must have good health, good hand coordination, keen vision, technical thinking and developed spatial imagination. Also, a representative of this profession must thoroughly know the structure of the welding machine, all the nuances of welding work, the basics of metal science, the process of preparing and processing parts, the properties of gases and electrical engineering.
Advantages of being a gas-electric welder
Every year the scope of metal use is constantly expanding, which means the need for qualified gas-electric welders will constantly increase. Accordingly, such specialists are in great demand in the modern labor market (even young specialists without work experience can easily find employment). The advantages of this profession also include:
- high level of payment - the higher the qualification of the gas-electric welder, the higher the salary level;
- prestige - despite the fact that this is a blue-collar profession, being a gas-electric welder is fashionable and honorable;
- great opportunities for additional income - a good specialist can simultaneously not only perform his duties at his main place of work, but also take orders privately;
- good prospects for career growth - with the appropriate level of qualifications and higher education, a representative of this profession can become an engineer or foreman.
Disadvantages of being a gas-electric welder
The main disadvantage of this profession is the harmful working conditions: due to the large release of heat and gases when performing welding work, electric and gas welders belong to the “hot shop” professions. In addition, work certified gas-electric welder has such disadvantages as:
- heavy load on vision - associated with the high brightness of the electric arc, as well as ultraviolet and infrared radiation;
- unfavorable working conditions - sometimes you have to work at high altitudes and in any weather;
- increased risk of injury - when performing welding work it is very easy to get burns and various injuries.
Where can you get a job as a gas-electric welder?
Get a job as a gas-electric welder it is possible either at special courses (but this option will allow you to become a good specialist only if you have work experience in a “close” specialty), or in secondary specialized educational institutions, where they provide training in such specialties as “gas-electric welding welder”, “welding production” " or " welding equipment operator ". At the same time, further employment does not depend on the choice of technical school, since all domestic secondary specialized educational organizations use almost the same training programs.
