Great country craftsman Ai Ai Guo: Make a "welding torch" that will never go out

Hunan Daily All -Media Reporter Cao Xian Peng Yahui Liu Yinan

35 years ago, a domestic steel company imported the world's largest oxygen making machine. How to make more than 20,000 welds seams without leakage under the deep cold conditions of -196 ℃, it is a major problem in the industry.

At that time, the young welders of the Xiangtan Iron and Steel Plant Ai Aiguo and his companions boldly adopted the international advanced double -sided and double -sided synchronous welding technology to successfully overcome this difficulty. Many foreign experts said after communicating: "Your Chinese craftsmen are not easy!"

After hearing this evaluation, Ai Aiguo secretly resolved: "Focusing on one thing in a lifetime and concentrating on being a good welder." In 53 years, Ai Aiguo was accompanied by nearly 20,000 days and nights with electric light sparks in welders.

On September 2, 2022, at the opening ceremony of the first great country craftsman's forum, the winner of the Seventh Medal and the 72 -year -old artisan craftsman Ai Ai shared the four points of "being a good worker and striving to be a craftsman": persistent focus, Always be the same; diligent in studying, mastering technology; courage to fight hard, be willing to suffer; be willing to dedicate, morality.

The great country craftsmen grew up from ordinary workers.

In the process of growing up, Ai Ai Guo also encountered many "block tigers". In the 1980s, the National Steel Factory of the National Steel Factory launched a new type of blast furnace of the "flow -type" blast furnace. Ai Aiguo and colleagues have tried a variety of solutions, but they were not discouraged. They fought for 3 months in a row and finally laid down this "hard bone".

In recent years, Ai Aiguo has overcome more than 400 welding techniques for domestic companies, and improves more than 100 welding processes. The products that Ai Aiguo and the team, together with the team, are widely used in super engineering such as the Hong Kong -Zhuhai -Macao Bridge, the Natural Gas Pipeline of the Sino -Russian East Line, Daxing Airport, and CNOOC No. 1.

The working environment of the welder is difficult, and Ai Aiguo is always working hard. Once, the company sent Ai Ai Guo to go to Xiangtan Food Machinery Factory to solve the problem of copper pot welding. At that time, it was August that colleagues used gas welding flames to heat the outside of the copper pot to about 600 ° C every day. Ai Ai Guo used asbestos plate pads in the pot, jumped in and welded for a few minutes. Essence

In the "Ai Ai Guo Welding Lab" of Hunan Iron and Steel Group Xiangtan Iron and Steel Co., Ltd., Ai Ai Guo is still fighting. "The more honors, the greater the responsibility." Ai Aiguo consciously assumes the responsibility of technical inheritance and teaches skills without reservation. In recent years, he has not brought less than 600 apprentices, and most of them have become the backbone of the enterprise. 80%of the welding workers above Xiangang Steel have learned technology with him.

"As a welded craftsman, I want to be a 'welding torch that never goes off. Where can the party's cause need it? Where can I give all the light and heat." Ai Ai Guo said emotionally.
