Is welding technology and automation electric or gas welding harmful to the body?

Electric welding and gas welding are available, because it is automatic and mechanically welded, so it is not harmful to people's bodies.

The difference between welding automation and electric welding;

1. The connotation of electric welding;

The broad definition of electric welding should refer to the welding category of electric fusion welding, and the common characteristics of this category of welding methods are: the base metal and filler metal material (sometimes without filler metal material) of the joint of the weldment are melted by electric heat, and they are fused with each other without pressure to form a weld, and a firm joint is formed after cooling and solidification. The welding methods that belong to the fusion welding category are:

Arc welding, submerged arc welding, MIG/MAG welding, tungsten argon arc welding, plasma arc welding, carbon arc welding, electroslag welding, electron beam welding

laser welding, etc. Usually what we call electric welding generally refers to manual arc welding.

2. The significance of welding automation;

Welding automation is a process or way of welding, welding automation can refer to the automatic welding of electric welding, or it can refer to the automatic welding of gas welding.

3. The difference between welding automation and electric welding;

Usually what we call electric welding generally refers to manual arc welding, which refers to a specific electric welding method, and welding automation is a process or way of welding.

In our country, welding operations need to be licensed, welders are the type of work that belongs to the access category, in the professional qualifications of skilled personnel, only five of the 81 types of work in the access category, welders are one of them, and the actual situation is that most of the industry practitioners are unlicensed operations. With the continuous standardization of technology and the relevant requirements of the industry, more and more people want to take a welding certificate, the advantage of the certificate is still very large, first of all, the salary of the certificate and the non-certificate are very different, often able to reach more than double or higher level. Therefore, the issue of short-term welder training has naturally become a concern for practitioners.

Welding as an industrial "tailor" is a very important means of processing in industrial production, the quality of welding plays a decisive role in the quality of the product, so, what is the future development of welding technology?

Industry outlook. With the development of production, welding is widely used in aerospace, aviation, nuclear industry, shipbuilding, construction and machinery manufacturing and other industrial sectors, in China's economic development, welding technology is an indispensable means of processing. After entering the 21st century, welding is an important part of the manufacturing industry, and the rapid development, so it has brought unprecedented development opportunities to the welding industry.

At present, China consumes 300 million tons of steel every year (about tons of welded structure), and needs about 750,000 welding machines, and the welding industry will continue to grow in the next 8 10 years.

Not during my university studies. When welding, safety protection measures should be taken, and the construction should be carried out accurately, and no illegal operations should be allowed.

Welding and automation are science and technology, of course, employment in the factory industrial area, the environment and climate are not as good as the urban area, more boring, and have a certain adverse effect on the body, but this major is good for employment, and the salary is stupid and high. All-aluminum alloy cars are developing, and automotive aluminum welding definitely needs more talents. Come on.

If you want to learn welding, it is best to take the examination in a good professional college, Harbin Institute of Technology, Tianjin University, Shanghai Hongjiao University, Shenyang University of Technology, Tsinghua South China University of Technology, etc.

There is damage, especially for the eyes, which are prone to presbyopia.

If it is a front-line operator, the impact on the body is still quite large. The domestic welding fume control is still relatively backward, do superficial articles, often breathe welding fumes, especially tiny particles, can directly enter the blood, the source of cancer.

Another is that welding is the effect of the light arc on the eyes. In fact, in factories, welding operations are often the worst working environment, and there are often cold operations, so noise is also very harmful to the ears.

Therefore, the welder industry basically relies on the body to eat, but in this industry, as long as there is technology, the salary is not worried, and it is generally the highest wage in the factory, among the workers.

However, if you are talking about welding technology and automation, it is also possible to operate a welding robot, which will hurt you much less. And it is very comfortable to operate the robot, the program number is OK, the robot automatically welds, you just need to track the quality and whether there is any abnormality. This is a technical job, and in the eyes of laymen and leaders, this type of work is both easy and valued.

The damage to the eyes is self-evident, the welding core of manual arc welding is made of metal wrapped in the coating, and the coating will react during electric welding, producing harmful gases to the human body, pungent, and very harmful to the lungs; If it is gas welding, then pay more attention to the correct use of gas to avoid **; There is also automatic submerged arc welding, this is much better, as long as the medicine is filled, the machine can be automatically welded. But don't be too stressed, every industry will have one kind or another injury, the key is to see if you like the industry or not.

If you do it, it hurts, and if you don't do it, you'll be fine.

The meaning of electric welding is very unclear, is it resistance welding, electron beam welding, electroslag welding, etc., or all welding methods related to electricity? If it is a general term for welding methods related to electricity, then welding automation is a method in electric welding (according to the degree of mechanization and automation, it is divided into: manual, semi-mechanized, mechanized and automated), welding automation is to realize the automatic control of the welding process, people only need to write a program, through computer control can be, no need for manual operation.

These are two different concepts, electric welding is a welding method, and welding automation is a welding effect.

But I can understand what you mean by asking is that you want to know what the advantages of welding automation over electric welding (traditional hand arc welding) are, right? This must be that welding automation is superior to electric welding, but in many occasions, welding automation cannot replace hand arc welding, such as downward welding of pipes, especially when it comes to filming, at least for now, it cannot replace manual welding.

The welding automation group should reflect the automation of rewelding equipment, and automation is to further reduce the work intensity of personnel and improve work efficiency. The scope of electric welding is very wide, and the knowledge of welding equipment is different, as long as the welding that uses electricity can be called electric welding. In practice, we call manual arc welding electric welding.

In fact, it is a very one-sided understanding.

Gas shielded welding is more harmful to the human body than electric welding

In addition to the safety characteristics of general electrode arc welding, gas shielded welding should also pay attention to the following points:

1.Gas shielded welding has high current density, strong arc light and high temperature, and produces high concentration of harmful gases under the action of high temperature arc and strong ultraviolet rays, which can be as high as 4 times and 7 times that of manual arc welding, so special attention should be paid to ventilation.

2.The high-frequency oscillator used in arc striking will produce a certain intensity of electromagnetic radiation, which will cause symptoms such as dizziness, fatigue and palpitations when exposed to more welders.

3.Rare metals such as thorium and cerium in tungsten electrode materials used in argon arc welding are radioactive, especially when the electrode is resharpened, radioactive dust is formed, and it is easy to cause diseases of the central nervous system.

No matter which job you choose, labor protection is necessary, and the working environment is also important, so I wish you all the best in your work!

I am doing electric welding, wear a glasses, so that it will not hurt the eyes very deeply, and the smoke will make the face peel, do a good job of protection, I use an exhaust fan to drain the smoke away, electric welding is very dry, to replenish more water, drink more water, and finally into the regular factory, there is insurance, in case of illness, I wish you a good job,

All are very large, and exhaust gases and soot will be produced during welding. Protective protection is a must. It is best to be a large state-owned enterprise or a foreign company. These companies do a good job of labor protection, and there are smoke and dust processors in the welding workshop.

Ultraviolet radiation is a greater point.

If there is smoke, the manual welding should be larger.

It's all the same, you have to protect yourself.

If you want to learn a professional skill from scratch in a short period of time, and be able to seamlessly connect to employment and get a high salary, then welding technology must be within your must! First of all, learn welding technology without worrying about employment, in the major recruitment**, the salary of welding-related positions is about 5000 10000. Not only is the job demand huge, but the salary is very considerable!

Second, the welding major is a short-term major, as long as you choose a good school, you don't need to invest too much time, you can get a job after studying. Students, we must recognize a reality, it is basically difficult to learn welding by yourself. "You will see it at a glance, and you will waste it as soon as you do it" This is a common problem in learning welding.

Welding is a very professional profession, if you want to learn well, you must go through professional training and constantly summarize experience, and ordinary training institutions do not have the corresponding equipment and facilities and industry specifications, if you can't learn the real technology, it is undoubtedly a waste of time and energy.

1.Various fields of industrial manufacturing, such as automobiles, aircraft, aviation, aerospace, home appliances, etc., are inseparable from the welding process, which is one of the most widely used basic processing processes, so learning welding is not worrying about employment.

2.With the country vigorously advocates industrial automation, intelligence, welding technology and automation has become the follow-up development direction, at present, all welding-related enterprises are promoting welding technology automation work, the prospect of learning welding automation is particularly good, and the salary is also high, but the premise is that your level and ability are high enough.

It's good to come out of the bachelor's degree, and a welder comes out of the junior college.

It's good to choose this major, but there is a shortage of talents in this area. But it is better to have a bachelor's degree or above, and it is very easy to come out and find a job.

At present, most of the welding work in the factory has adopted automatic welding technology, which has reliable welding quality and shortens the production cycle; Unlike before the 90s, which relied on crowd tactics, welders were labor-intensive. Therefore, the welding quality must be guaranteed by welding equipment and technology, which reduces the human factor.

The future is very good, especially the welding robot tooling.

Manual welding is mainly pneumoconiosis caused by welding smoke, if the welding area is well ventilated, there is generally no big problem, and I haven't seen how many old welders are sick after retirement, one is the working environment, on the other hand, self-protection;

When argon arc welding, we should pay a little attention to high frequency, many magazines at home and abroad say that high frequency is harmful to health, but there is no clear harm until now, everything is still guessed; At the same time, there are some tungsten electrodes with trace radioactivity (such as thorium tungsten electrodes), but this kind of tungsten electrodes are not used in China, so be careful not to inhale dust during grinding;

Semi-automatic gas shielded welding should not be carried out in a closed environment, such as drilling into the container for welding, and attention must be paid to ventilation to prevent suffocation when welding in the cabin and tank;

And automatic submerged arc welding is basically nothing, don't touch the place you have just welded, it will be hot!

Welding is known as the industrial sewing machine, as long as the metal connection is used where the welding needs to be welded, according to statistics, 50-70% of the steel production is required to be welded after the use of processing, how much is China's steel output every year? How many job opportunities do you say? Of course, employment is not guaranteed, and if you get a place in the national welding competition, congratulations

There are definitely high-paying opportunities waiting for you!

I graduated from this major in 09, don't misunderstand the major. In fact, when you hear this profession, your first feeling is that you are a welder, which is a big mistake. The major of the school is not to train welders, but welding engineering and technical talents.

You don't need to weld at all, you only need to come up with the welding process, solve the technical problems in the welding construction process, calculate the amount of welding materials, etc. There are very few bachelor's degrees in welding, so the employment of junior college is better, and it is one of the top 10 green card majors. As long as you study hard, employment is not a problem, it's very hot!

Hope it helps!
