How to practice electric welding well How to weld electric welding well

In addition to mastering the theoretical knowledge, beginners should have a good grasp of theoretical knowledge. In the actual operation, the reasonable selection of current is the key, the current is small, it is difficult for beginners to start the arc after starting the machine, can not transport the strip continuously, the weld is too narrow and too high, can not form an ideal molten pool, and the weld can not be formed. If the current is too large, it is easy to form undercut, collapse, breakdown, excessive spatter, ultra-wide weld, and difficult to form weld.

In particular, it is important to regulate the current at any time, and the simple way is to find a useless material (its material and thickness should be close to the weldment to be welded) after starting, easy to start the arc, the arc light is not large, and the spatter is not much. In actual operation, the welder must correctly select the current according to the thickness of the material, the welding content, the welding method, the material and the process requirements. The correct selection of current is explored by welders in long-term practice, because the technical basis of welders is different, and the current used when welding the same facilities is also different.

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.

Practice more, no matter what you do, learn from scratch, start small, and take your time.

Start with fillet weld and then butt weld.

1. The new welder is easy to burn out the iron plate, and the important factor is that the thickness of the iron plate is not certain, so it loses its sense of proportion when adjusting the current size, resulting in the burning of the iron plate.

2. When welding, the hand needs to be kept stable and welded, and the arms must be clamped tightly to avoid shaking, so that the welding can be uniform and beautiful.

3. When welding, the zigzag and dot type are generally used for welding, so that the welded seam texture is clearer.

4. When welding, the welding rod and the iron plate should be kept at an angle of 45 degrees, which is conducive to the uniform distribution of molten iron, and the weld will be smooth.

5. When carrying out the upward welding operation, because the molten iron is easy to fall, it is necessary to take the form of spot welding, so that the sintering will be more firm.

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, but the current training of welding professionals is far from meeting the needs of social employment. In particular, there is an extreme shortage of talents in the fields of second guarantee welding, argon arc welding, and manual arc welding technology, which has created a large demand for welding skills, urgent demand, and high salary. Ordinary professional welding talents, the monthly salary can reach 6,000 to 10,000 yuan, and the special welding industry is even as high as tens of thousands of yuan.

This kind of personnel does not need to have a high degree of education, as long as they have the spirit of being practical and capable, hard-working, and learning technology, they can be employed with high salaries. It is hoped that aspiring young people, laid-off workers, and veterans who want to master welding technology will realize their dream of high wages as soon as possible and drive their families out of poverty and become rich.

Question: Ok.

1. The basic skills of the body and body are stable, and it is necessary to squat and stand steadily, and adapt to the welding operation of various postures.

2. The hand should be steady, if you can pour out a uniform and straight water line with the kettle, the hand is very stable when welding the electric weld.

3. The eyes should be clear, the hands should be accurate, distinguish the molten iron and the slag of the coating, control the molten iron, and separate the slag.

4. Be careful, be able to persevere, summarize more, ask the master for advice, master the characteristics of the electric welding machine, summarize the common welding current of weldments of different thicknesses, summarize the common current of various welding positions, summarize the common welding current of weldments of different materials, summarize the welding precautions in different environments, and ask questions about the practice process.

In practice, it is to weld more, operate more, connect some welding projects, and constantly improve skills and technology.

I hope the above content can help you, dear, I wish you a happy life, all the best, happy and happy. [Flowers] [Flowers] [Cow Blessing To] [Niu Fu To] [Heart] [Heart].

If you are a novice to learn welding, you can practice these three transport techniques first, which can make you progress faster.

Electric welding for three and a half days will be done if you don't learn Find a master and follow it for a few days, but if you want to do it well, it is not so fast Or the factory likes to recruit old welders.

To learn welding, you need to find the right master, and you can only pay it.

Learn skills carefully.

And don't forget about the theory.

Theory is related to the need for a special work operation certificate, and it is necessary to take the test before you can practice.

While learning technology, you must take the operating certificate.

Go to formal training to learn and learn, so that you can learn it. Hefei Red Star School is a good choice.

This has something to do with World ...... Warcraft

Learn mechanical drawing first.

Able to read drawings.

Understand welding symbols.

Only then do you know the welding, how many welding angles, how the weld is and so on. Including: material structure, welding drawing, welding principle, structure and working principle of various welding equipment, manual arc welding, gas welding, gas cutting, argon arc welding, carbon dioxide gas shielded welding operation process and practical operation methods, as well as various welding quality testing.

Welder is a special type of work, arc light to human eyes and ** if not protected will be harmed, just welded weldments do not wear good gloves to move will burn hands, knock welding slag if not protected will also hurt people. At the same time, the operability of welders is very strong, and most people want to learn welders well, the reason why some people lose interest is because people feel that the effort is not proportional to the progress of the welding level, coupled with the damage of the arc to the eye or the damage of the weldment opponent pushes these people away from the door of learning.

Handle welding is the most widely used, simple but the most test of hand stability technology, for reference.

Before learning electric welding technology, I should have an idea, what company I want to enter, I need to learn electric welding or carbon dioxide gas shielded welding or argon arc welding, which positions to learn, whether it is flat welding, flat fillet welding or horizontal welding, vertical welding, vertical welding, and vertical welding. If you learn it, you can apply it in your work, and you should be targeted.
