Electric welding, gas shielded welding, argon arc welding is more practical to learn 20

are more practical.

At present, the training of welding technical schools is a variety of welding training.

Including electrode hand arc welding, tungsten argon arc welding, gas arc welding, gas welding, gas cutting, plasma cutting, trying to cut and other courses.

It is difficult for a single type of welding to adapt to society at present.

Electrode arc welding, suitable for repairing workpieces, with the characteristics of flexible operation. The disadvantage is that the welding efficiency is low, and the technical requirements for welders are high.

Gas shielded welding, suitable for thin plate welding, as well as mass production and manufacturing of welded workpieces of medium thickness plates, with high efficiency and low comprehensive cost. The disadvantage is that the wind resistance is poor, which is suitable for workshop welding operations.

TIG welding, in a narrow sense, is tungsten TIG welding, (MIGG welding also belongs to the category of gas shielded welding). It is mainly used for non-ferrous metal welding, low carbon steel, low alloy steel, boiler pipes and other precision parts for root welding, etc.

However, electrode arc welding is a basic skill, and it is much easier to learn the electrode arc welding after learning well.

It's not that they have their own advantages, manual arc welding is the most widely used, its advantage is that it is flexible and can be welded in any position, but it cannot weld thin parts, and the efficiency is also low. Gas shielded welding is good, thin parts can also be welded, thick parts can also be welded, the efficiency is also high, is the reason for poor flexibility, for there is a wire feeder in the back is inconvenient, argon arc welding thin is the most suitable, thick is not suitable, the key is that the efficiency is too low, manual arc welding is the most test technology to learn it, in learning other welding is much better. Of course, it's all good to learn.

Of course, it is to learn the electric welding first, manual arc welding can exercise and deepen the depth of the welding operation, more able to contact the handle, the beginner is generally not very stable, the transport bar is easy to tremble, after the welding foundation is laid, in learning some gas shielded welding, in fact, the application of manual arc welding is very extensive, if you are in the installation industry, manual welding and tungsten argon arc welding are widely used, and the income is about 4500-6000 yuan, believe me, I am the thirteenth construction company of Sinochem.

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.

Learning electric welding is the hardest, as long as you learn electric welding. Sub-arc welding, oxygen welding is very simple to learn. Electric welding is widely used, argon arc welding is mainly used to weld stainless steel, and temporary use of oxygen welding should not be common.

Yes, but it must be based on manual arc welding, followed by sub-arc, you can learn CO2 gas shielded welding by hand, and you will learn it quickly

In fact, as a welder, these techniques should be mastered, and the cut is bypassed, and the basic technology is almost the same, but the instruments and equipment are different.

Gas shielded welding is the most practical inside the big factory.

The welding method of important structures is generally manual arc welding.

Second, it is better to weld well.

The second shielded welding (full name carbon dioxide gas shielded welding) process is suitable for low-carbon steel and low-alloy high-strength steel various large-scale steel structure engineering welding, its welding productivity is high, the crack resistance is good, the welding deformation is small, the deformation range is large, and the welding of thin plates and medium and heavy plates can be carried out.

Welding preparation: 1. Before welding, the joint cleaning requires that the burrs, oil, rust and oxide scale that affect the quality of the weld within 30mm on both sides of the groove must be cleaned.

2. When the construction environment temperature is lower than zero or the carbon equivalent of the steel is greater than that, and the structural rigidity is too large, and the object is thicker, preheating measures should be used before welding, the preheating temperature is 80 100, and the preheating range is 5 times the thickness of the plate, but not less than 100mm.

3. When the thickness of the workpiece is greater than 6mm, in order to ensure the welding penetration strength, the butt edge of the plate should be cut V-shaped or X-shaped, the groove angle is 60°, the blunt edge p is 0 1mm, and the assembly clearance B is 0 1mm; When the thickness of the plate is 4 mm, the butt edge of the thicker plate should be skewed.

Operational Points:

1. The joints with bevels in vertical or inclined positions must be welded from bottom to top, and the butt butt and vertical fillet welding of thin plates without bevels can be welded downward; Flat, horizontal and vertical butt joints can be welded in the left direction.

2. When the wind speed is greater than 1m s in outdoor operations, windproof measures should be adopted.

3. A reasonable welding sequence must be selected according to the structure of the workpiece to be welded.

4. Arc striking and arc extinguishing plates of appropriate size should be set at both ends of the butt.

5. The dirt in the hose and the splash of the nozzle should be cleaned frequently.

Each of the two types of welding has its own advantages and characteristics.

1.Manual tungsten argon arc weld is of high quality, and argon arc welding is suitable for welding non-ferrous metals and alloy steels that are easy to oxidize (at present, AL, MG, Ti and their alloys and stainless steel are mainly used); It is suitable for single-sided welding and double-sided forming, such as root welding and pipe welding; Tungsten TIG welding is also suitable for thin plate welding.

2.CO2 gas shielded welding features:

Small welding stress and deformation, suitable for all-position welding, high CO2 gas, low welding power consumption, low sensitivity to rust, not easy to produce porosity, low hydrogen content of weld, good crack resistance, high productivity; Auxiliary machines can be used to automate production.

Now the manufacturing industry has been widely used, such as: bridge construction welding, automobile manufacturing, shipbuilding, steel structure, machinery manufacturing, pipe welding industry and many other fields.

Argon arc welding and two welding have their own advantages, according to their own situation to choose, it is recommended to go to a more professional school to study, recommended to Zhengzhou technician [North Electric Welding School], Zhengzhou Technician North School is mainly based on actual combat, training consumables are sufficient, learning + certification, heavy practical operation is based on practical training, teachers teach in small classes, you can [apply for tuition-free admission places].

The three most commonly used welding methods in production: electrode arc welding, argon arc welding, and secondary welding. These three types of labor are in the greatest demand, with different technical levels and different wages. The more you learn, the greater the scope of employment, and it is best to be able to study all of them.

Argon arc welding and two-shield welding are commonly used welding methods, there is no saying which is better, in actual use, it is still necessary to choose the appropriate welding method according to the welding material, requirements, occasions, etc. For example, although the welding efficiency of argon arc welding is low, the welding quality is better than that of secondary welding, the welding heat input is small, and the welding deformation is small.

So depending on what the welding requirements require, then choose the right welding method.

I think it's best for you to learn TIG welding, because the salary of such an TIG welding is very high, and the professional ability required is also very strong, so if you learn, you will also find yourself a better job.

You can learn to weld second, because it is now widely used and can be used in many places.

Summary. Which is stronger, TIG welding or electric welding? Electric welding ironElectric welding iron is relatively strong.

TIG welding is specialized in welding stainless steel, but welding iron can also be welded, but TIG welding iron is not as strong as stainless steel. The degree of harm of argon arc welding is relatively greater than that of electrode arc welding, but it is not so large that it is daunting, infrared radiation is about 1 times that of ordinary electrode arc welding, and the ultraviolet radiation produced by argon arc welding is about 5 20 times that of electrode arc welding. When welding in a confined space, the concentration of ozone can increase to a dangerous level, and during the welding process, harmful gases such as carbon dioxide and carbon monoxide and metal dust will be produced, which will cause certain hazards to welders.

Therefore, we should do a good job of protection in the welding process, choose the material of the electrode, and try to choose cerium tungsten with low radioactivity. When grinding electrodes, wear masks, gloves, and wash your hands after work to minimize the harm.

Is it possible to use argon arc welding for pipe welding?

Which is stronger, TIG welding or electric welding? Electric welding ironElectric welding iron is relatively strong. TIG welding is specialized in welding stainless steel, but welding iron can also be welded, but TIG welding iron is not as strong as stainless steel.

The degree of harm of argon arc welding is relatively greater than that of electrode arc welding, but it is not so big that it is daunting, infrared radiation is about 1 times that of general fiber search through electrode arc welding, and the ultraviolet radiation produced by argon arc welding is about 5 20 times that of electrode arc welding. When welding in a confined space, the concentration of ozone can increase to a dangerous level, and during the welding process, harmful gases such as carbon dioxide and carbon monoxide and metal dust will be produced, which will cause certain hazards to welders.

That is, the welded pipeline can not be all used argon arc welding, generally argon arc welding bottom, hand weld cover surface?

Dear Yes.

Which one is easier to learn? The master tells you about the experience.

Answer: Electric welding is easier to operate than argon arc welding, and each has its own advantages. However, electric welding is widely used, and welders are also more common; TIG welding has few applications, but it must be very "popular" to find a job. Electric welding is a special job, in fact, no matter what you do, you will have a future if you learn well.

If you choose electric welding, you have to endure the feeling of smoke and fire, wear thick clothes in summer, and the harm of arc light radiation and soot, argon arc welding radiation can be 15 times that of hand welding, or even higher. Ask a question, yes.

Ask questions for a month but don't know which welder to choose.

As for the welder, it is relatively wide, and it is easy to find a job.

Personally, I think argon arc welding is easy to learn, but as far as these two types of welding are concerned, argon arc welding is relatively harmful to the human body! Therefore, it is not recommended to learn argon arc welding.

Electric welding is easy to learn, and the radiation of electric welding is also the lowest. TIG welding will do the trick. And the degree of harm of argon arc welding is relatively greater than that of electrode arc welding, but it is not so big that it is daunting, infrared radiation is about 1 times that of ordinary electrode arc welding, and the ultraviolet radiation produced by argon arc welding is about 5 30 times that of electrode arc welding, when welding in a limited space, the concentration of ozone can be increased to a dangerous degree, and in the welding process, harmful gases such as carbon dioxide and carbon monoxide and metal dust will also be produced, which have certain hazards to welders.

It's best to study after you get married. There are also those who get married after doing electric welding, and some can give birth to healthy babies. This is not easy to say, recommended answer 3:

The differences between gas shielded welding and argon arc welding are:

1. The definition is different: gas shielded welding refers to the welding method of carbon dioxide or argon protection, without welding rod and welding wire. TIG welding is a welding technology that uses argon as a shielding gas.

2. Different uses: gas shielded welding is mainly used in aluminum and aluminum alloy, copper and Fengjuqing copper alloy, magnesium and magnesium alloy, titanium and titanium alloy, high-temperature alloy and other welding, and has a wide range of applications in many important industrial sectors. TIG welding is mainly used in nuclear energy, aviation, aerospace, shipbuilding, electronics, metallurgy and other industries.

3. The hazards are different: the hazard of gas shielded welding is that arc and dust have a great impact on the health of welders. The radiation hazards that welders are often exposed to in welding include strong light, infrared, ultraviolet rays, etc. The X-rays produced by the electron beam in welding can affect the health of the welder.

The ultraviolet radiation intensity of argon arc welding is much greater than that of general arc welding, so a large amount of ozone and oxynitride will be produced during the welding process; Ozone, in particular, is concentrated well above the reference health standards. If effective measures are not taken, these gases have a great impact on human health and are the most important harmful factors of argon arc welding.
