Customized work clothes manufacturers take you to know welders under high temperature (I)

Electric welders under high temperature: work in 60 ℃ iron box for more than 8 hours, wear work clothes for 1 month and discard them

"Due to the large amount of welding flowers produced during welding, the clothes we wear will burn a lot of holes every day. Normally, a work clothes can be worn for three years. Here, they can only be worn for one month at most, and they will be scrapped." On July 24, the second day of the summer, at a construction site in Fuyang, Anhui Province, the sweaty electric welder Zhang Renkun introduced his work while drinking water. The picture shows Zhang Renkun working in the box on July 24.

Zhang Renkun is from Heze, Shandong Province. A month ago, he and six other villagers came to Fuyang, Anhui Province to take charge of the welding of the sliding platform in front of the Fuyang high-speed railway station. It is understood that the sliding platform in the charge of Zhang Renkun and several other villagers is all made of iron plates. In addition to the joints on the platform surface, all the joints inside the platform should also be welded.

"These days are continuous high temperatures, and the maximum temperature outside has reached about 37 degrees, so at noon, the temperature in the box under the sliding platform can reach about 60 degrees." Zhang Renkun said, because the box space is small, the heat and smoke generated during welding are dissipated slowly, so when working, we have to use a fan to blow continuously from outside to inside, so as to reduce the temperature in the box. At the same time, it can also disperse the smoke generated during welding and reduce the impact on the vision of the welders.

So, what is the feeling of working under the high temperature of about 60 degrees? "Because the air inside doesn't flow very much, it feels very hot and stuffy when you get inside, and you feel like you can't breathe. Don't mention working in such an environment, but you will soon sweat when you stay inside for a while." Master Zhu said that the sliding platform is supported by multiple boxes, and each box is an independent space with a length of about 4 meters, a width of about 4 meters, and a height of more than 2 meters, In addition to an elliptical hole between the box and the box, they work in such an almost closed space every day.

The photographer saw a rectangular hole on the sliding platform, in which a simple ladder welded with steel bars was placed. Zhang Renkun and his fellow villagers work inside the box through this ladder every day. "The ladder was scorched by the sun until noon. If you don't wear gloves when you come up from the box, you dare not touch it."

Although the temperature at the work level is high, Zhang Renkun and his colleagues wear thick work clothes and are "fully armed" from head to foot. He said that the biggest difference between electric welders and other types of work is that they will produce a large number of welding flowers during work. "If you don't wear work clothes to protect yourself when you work, the exposed parts are easily burned by the welding flowers generated during welding. Therefore, in order to prevent the welding flowers from falling on your body, you must" fully armed ", wear long-sleeved work clothes outside, and also wear thickened underwear inside. You can't have less than one hand cover, work cap, and protective mask."

The picture shows the dense holes on the work clothes of an electric welder burned by welding.

Because of sweating a lot, Zhang Renkun and his colleagues each carried a water cup for their own use, in addition to the large bucket of mineral water prepared on the construction site. He said that the model of the water cup they used was relatively large. It could hold more than 1 kg of water at a time, and was usually drunk twice. "Under normal circumstances, a person should drink more than four drinks a day. He sweats from work until he finishes his work. His clothes have not been dried."

Zhang Renkun said that among their fellow villagers, the oldest is 44 years old, and the youngest is only 35 years old. "Everyone has been engaged in electric welding for more than 10 years, and often goes to all parts of the country to do odd jobs or contract jobs, and the average income is about 400 yuan a day."

He said that the eyes would be uncomfortable after facing the welding gun for a long time, which is called "piercing" in their jargon. After "drilling", the eyes will be very uncomfortable, and often will not stop crying. The best way is to use frozen mineral water. However, for them, "drilling" has become used to.

It is understood that due to the tight construction period of the high-speed railway station, Zhang Renkun and his fellow villagers have to work in such an environment for more than 8 hours every day.

[Adherence under high temperature] Electric welders - with sparks!

The days of high temperature and heat,

It's as hot as a steamer outside,

However, there is a special type of work,

Not only do you need to wear long sleeves and thick clothes in the hot summer,

It also needs to endure the heat of 1500 ℃.

They are welders who deal with high temperature every day.

On the morning of July 18, the reporter saw in the production workshop of Zhenjiang Wande Machinery Co., Ltd. that the electric welders were busy and nervous, and the faces of each operator were red with the high temperature of the heated steel plate.

It is now three dog days, and the environment has reached an average temperature of about 34 degrees. There is a large barbecue mode outside and a concentrated heat wave in front of it, and the staff must wear long clothes to ensure their safety. Three factors make the staff's working environment like a big steamer.

Tang Wei, who has been engaged in electric welding for 13 years this year, was dripping sweat from his face when he took off the protective cover.

Tang Wei, an electric welder, said that when doing electric welding and gas shielded welding, we can't blow a little wind. The work clothes are relatively thick. The clothes are wet several times a day, and they are wet and dry. We stick to one for the family and the other for the company.

In order to cool down the workers in time, the company has also prepared a cold drink room in the workshop to do a good job in heatstroke prevention and cooling. These workers under high temperature, who are unknown in their ordinary positions, are devoting their light and heat. They are not only shedding and paying sweat, but also a heavy responsibility.

Gloves, masks, and goggles are everyday clothes. Noise, arc light and high temperature are accompanied by them.

Hu Hongbo, 49, is a welder in the equipment department of Hubei Dali Food Co., Ltd. He not only won the first prize in the argon arc welding competition of the 2016 Vocational Skills Competition of Hanchuan Federation of Trade Unions with his excellent welding technology, but also brought a number of skilled welders to the company.

Sparks splashed all over and it was hot and stuffy. On the hot day in July, Hu Hongbo put on a tight protective mask and entered the welding workshop.

After entering the company in 2005, Hu Hongbo has never been good at it. He has tried to sum up his experience step by step. The next year, he became the head of the welder group with his pragmatic character and superb technology.

It is easy to get started, but difficult to weld well. It is even more difficult to weld high-quality products. Zhang Yingsheng, the vice director of the company's equipment department, said that the company often carries out new product development and development, including the welding of new products with complex structure and high standards, which requires continuous improvement of the process. Such tasks are usually led by Hu Hongbo.

If defects such as dents and cracks are formed during the welding process, it is easy to cause impurity accumulation or stress concentration in the process of putting the pipeline into use, resulting in various adverse consequences. "The butt joint should be good and flat. When welding, the argon filled in and the welding current should be just right, otherwise there will be a dead corner." Hu Hongbo said that in the food industry, if the pipeline is welded because of incomplete penetration and incomplete fusion, it will be fatal for the transportation of materials.

Welders are special types of work. They should wear heavy protective equipment in summer and touch cold tools in winter. Yesterday, the high temperature in the welding workshop reached 43 ℃. Hu Hongbo's goggles were already covered with moisture and sweat was flowing on his face, but he had no time to wipe them. Because the electric fan cannot be blown during the welding process, the blowing of the electric fan will affect the welding forming and the welding effect.
