"Worker Academician" Chen Jingyi: The Heavy Weapon of the Country "Welds" Guards See the truth in the subtleties

Zhongxin Wanghai, 5 May -- Title: "Academician Workers" Chen Jingyi: The Defender of the Heavy Weapon of the Country "welds" sees the truth in the subtleties

This "May Day" holiday, Chen Jingyi, chief technician of China Shipbuilding Group, chief technician of Jiangnan Shipbuilding (Group) Co., Ltd. (hereinafter referred to as Jiangnan Shipbuilding), and winner of the 16th China Skills Award, rarely stopped the welding torch in his hand to accompany his daughter who was about to take the college entrance examination; Just two days before the holiday, after more than a year of research and continuous experimentation, a new welding process he tackled made a major breakthrough, which made the second generation of Jiangnan shipbuilding "welding king" after the founding of New China quite excited.

The China Skills Award is the highest government award in the field of skilled talents in China, and it is a top honor given to high-skilled talents, and is known as "Worker Academician".

Chen Jingyi recalled that when he learned the news of winning the China Skills Award, he was working on a key project welding problem on the "Fujian Ship", "I was very happy, I felt that my skills were recognized, and my efforts were rewarded accordingly." ”

Chen Jingyi has his own views on the title of "worker academician". In his opinion, the research of front-line workers is different from the research of academicians, and front-line workers are still based on skills, and on this basis, there are innovations and improvements. For example, he said, in the field of welding, skilled personnel first have good ideas, and then practice, and the final result must be reflected in improving quality and efficiency in the production process.

With more than 30 years of experience, Chen Jingyi adheres to the concept of "research is for application", constantly explores how to overcome the welding of new materials, and has achieved significant research results in the welding process of dissimilar steel, non-ferrous metal, high alloy steel, low temperature steel and castings.

In the eyes of everyone, all major national projects undertaken by Jiangnan Shipbuilding, all major projects encounter welding problems, Chen Jingyi always rushes to the forefront, always takes the lead in key technology research, China's completely independent design and construction of aircraft carrier "Fujian ship", large surface ships "Nanchang ship" and "Haikou ship", polar research ship "Xuelong 2", ocean-going survey ship "Yuanwang 7" and other well-known big countries and heavy weapons have his struggle, have recorded the story of his overcoming key technical problems, is a veritable heavy weapon of the country." Weld "Guardians.

In the process test and welding technology research of special materials in the early stage of the construction of the "Fujian Ship", Chen Jingyi led a number of welders to complete the segmented construction of the "Fujian Ship" simulator, successfully broke through the high-efficiency welding technology of a variety of high-strength steel of the "Fujian Ship", and successfully applied it in the construction of the actual ship, which increased the welding efficiency of the high-strength steel of the hull structure by 2-3 times, which not only greatly shortened the construction cycle of the Fujian ship, but also made the ship save nearly <> million yuan in welding consumables and labor costs in terms of construction costs.

In the construction of "Nanchang ship", Chen Jingyi innovated the process flow, strictly controlled the assembly gap and accuracy of important equipment, adopted more than 10 welding processes and nearly 20 types of tool tooling, successfully controlled the construction accuracy and strength requirements of the equipment, and completed the production of key structures with high quality and efficiency, providing a technical basis for the production of similar structures of subsequent series of ships.

For Chen Jingyi, he still remembers the "most difficult hurdle" in his work: when simulating the structural welding process of a national strategic product, due to the narrow position of the frame space and the weld to achieve 100% nondestructive testing, he thought of the method of carrying a rotating frame and placed a cylindrical head with a diameter of 3 meters here. Chen Jingyi erected 3 I-beams on the smooth surface, repeatedly "cut" and then welded, which played a role in reaction force and reduced the probability of deformation in the welding process. After 1 month of welding, it was finally completed, and it became his longest "work". "It's hard, it's hard, but I have to do this craft well."

While actively carrying out the application of new technologies, the promotion and application of operating standards and patents led or participated in by Chen Jingyi has also improved the technical level of the construction of national heavy weapons.

Chen Jingyi said that the work of electric welding is dirty and tiring, but welding is a "beautiful and wonderful art" that must be seen in the details. "Personally, I chose welding out of my desire for stable work and curiosity and interest in the technology."

In 1989, Chen Jingyi came to Shanghai to become a "Shanghai drifter", and in 1990, he entered the Jiangnan shipbuilding machine assembly workshop and became a ship pipe welding apprentice. After more than a year of wandering, Chen Jingyi felt that this job was not easy to come by, and from the moment he entered the machine workshop, he secretly decided that he must learn the craft of welding.

At work, Chen Jingyi rushed to do whatever work he wanted, welded a pipe, took the teacher to weld another pipe after passing the inspection, and rarely rested. Chen Jingyi's proactive attitude is deeply liked by the teachers, who provide technical guidance to him whenever they have time. In this way, his welding technology has advanced by leaps and bounds, and he can complete various welding tasks independently in less than two years.

Jiangnan shipbuilding has a long history and has always had the habit of inheriting masters and apprentices. "Craftsmen must not only be highly skilled, but also cultivate talents for future generations", this is the tradition inherited by Jiangnan Shipbuilding. Today, Chen Jingyi is like a master, the welding technology he has learned and mastered is unreservedly passed on to young welders, he has trained more than 9 welders in 500 categories of special steel for Jiangnan Shipbuilding with the national skill master studio as the carrier, in the words of his co-workers, "Chen Jingyi used the welding torch in his hand to create a bond of inheritance." ”

Since his first participation in welding competitions in 1996, Chen Jingyi has participated in various domestic and international competitions for many times, won gold medals repeatedly, and transformed his experience of "gold winning" into results, cultivated a large number of welding high-skilled talents, and enjoyed a reputation inside and outside the industry. His apprentice Chen Yifeng won the first place in the 2012 "Jiake Cup" International Welding Competition, and won the title of "National Technical Expert" in the same year; Led apprentice Chen Guogan to the Czech Republic to participate in the 19th "LINDE Gold Cup" International Welding Competition, and won the first place in MIG/MAG gas shielded welding.

"We should pay attention to the selection of front-line skilled talents to participate in the skills competition. A platform of skill competition can cultivate a skilled talent, can drive a large number of people, to lead the face, everyone's creativity, work enthusiasm are mobilized. Chen Jingyi believes that it is most important for young apprentices to endure hardships and like welding, because only love can persist. He also believes that with the improvement of China's high-skilled talent system and policies, the improvement of the training system, and the stronger social atmosphere of respecting skills and respecting labor, more and more young people will embark on the road of serving the country with skills.

"Over the years of work, I have deeply realized that the development of the motherland also brings opportunities for personal development. I will continue to use the welding torch in my hand to 'weld' more powerful heavy weapons and cultivate more outstanding skilled talents. Chen Jingyi said. (End)
