Can a welder weld, how long does it take to weld and there is no harm to the body?

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.

Mainly for the eyes, the arc light has a radioactive hazard to the body, as well as the lungs, the smoke from welding, I do this, although I know, but what can I do? Life is forced! Be protected.

You need to know that the smoke and dust generated in the welding process still stay in the strong electromagnetic field for a long time, which is harmful to the body, so it is very important to have regular special physical examinations!

Books on welding expertise or consultation with the doctor at the Occupational Disease Diagnosis Center can give you a satisfactory answer.

Let's give you a reference: Don't let the arc light shine directly on the **, otherwise it will cause **disease or deficiency. Your eyes will deteriorate badly after you turn 60 onwards, so try to protect your eyes as much as possible.

When welding, there can be no ferrous metal on the body, such as belt buckles and keys, because electric welding can form a strong secondary magnetic auxiliary injection around the metal.
