Bean Castle Print: Welder of Nuclear Power "Great Artery"

[Struggler Zheng Youth · First -line Story] Bean Story Print: Weller of Nuclear Power "Great Arterial"

In the workshop of the CAP1400 modular prefabricated factory, the humid air is wrapped in rust. A young man wearing a thick welding uniform guards near a thousand degrees of welding machines, accompanied by dazzling arc light and splashing welding slag. Every time he breathed, moved, and changed his posture, he moved steadily in his hands.

The young man is the youngest senior technician of Shandong Nuclear Power Equipment Manufacturing Co., Ltd. Dou Cunjin.

In 2003, the 14 -year -old beanca seal entered the Jinan Technician College to study welding. When he first came into contact with welding work, he had large and small welding scars on his arm, legs, and belly. "Otherwise, let's change the door." Parents looked very distressed.

"No, since I learned it, I have to stick to it!" Dou Cun's slightly green face showed his determined eyes, no matter how hard or tired, he had no complaints. Soon, he became the best among his peers, and was affirmed many times during the internship work.

In 2008, it coincided with the peak period of the construction of the three -generation nuclear power AP1000 in my country, and was eager to learn more welding methods and technologies with beans and printed, and came to Shandong Nuclear Power Equipment Manufacturing Co., Ltd.. Originally, he thought that he could show his skills with his existing internship experience. However, when he saw the master welded the materials strictly with a beautiful fish scale pattern, he felt a huge gap.

"The original nuclear electric welding has higher standards and craftsmanship requirements. I can't drop the chain!" He turned around and had been thinking about how to improve his skills. As a result, the bean seal collects abandoned welding sticks every day after work, and worked overtime to practice welding. As soon as I have free time, I went to ask the masters to ask the masters. It was 10 % in the morning and night. This is more than a year.

In these passing time and consumed welding, he found that the strip electrode arc welding technology used by the company's stainless steel welding was spending time consumable. In a welding, he boldly put forward his idea: "I think stainless steel welding is better to use the" carbon dioxide gas protection welding "."

In a few months, the company's test results completely confirmed his thoughts, and "two -guarantee welding" is indeed much better than arc welding. The "two -guarantee welding" generally implemented on stainless steel has increased production efficiency by nearly tripled, which greatly saves production costs.

Since then, Dou Cun Yin ran on the way to explore new crafts and master new skills, and put forward more stringent requirements for himself: "If you pay ten times the effort, it is not good to do it, then you will work hard. Weld. "

In 2017, important progress of the major CAP1400 demonstration engineering nuclear power plant in the water pile has made important progress, marking that my country has a large advanced nuclear power technology with independent intellectual property rights. "my country's independent innovation 'big nuclear power' sailed! This is even greater than previously introduced foreign AP1000 power generation!" The bean deposit seal participating in the CAP1400 project is difficult to hide excitement, but the problem has followed.

Nuclear -level pipelines are the "great arteries" of nuclear power equipment. The increase in diameter and increased thickness of the pipeline increased the difficulty of welding. The original experience was difficult to come in handy at this time. The shift is completed day and night.

"Although it is hard to participate in the CAP1400 project, each of us is full of pride. This is our Chinese creation. Its welding must be seamless." Doing the work must be perfect. The belief is also the benchmark he established.

The heart is in one art, and its art must work. Different from conventional welding, nuclear welding has clear regulations on the requirements and classification of personnel qualifications. In order to prove your ability and create more value, beans not only have conventional welding qualifications at the nuclear power site, but also have more than 20 qualifications such as pipelines such as carbon steel, stainless steel, double -phase steel and structural modules. At the age of 25, he was rated as a national advanced welding technician. At the age of 27, he has been a national technical expert. He has maintained a record of 100%of the welding rate for many years.

"It is my greatest luck to be able to advance with the autonomy of the three generations of nuclear power in my country. In the future, I will still contribute to the manufacturing and high -quality development of nuclear power equipment through continuous efforts and continuous learning." Dou Cunyin said.
