Although Zhao Jingfu has a low education, after years of hard research, his mastery of welding materials and technology has reached the level of an expert, and he has become one of the few senior technicians in Fengyang Shipyard.

In particular, Zhao Jingfu has a unique skill, which is the welding technology of super-thick steel plates. This is what he has figured out based on the years of experience and his own understanding of the old workers in the shipyard. It can not only ensure the welding strength while increasing the welding speed, but also know that on-site welding of super-thick steel plates has always been a difficult point in the welding field, especially putting great requirements on the quality and physical strength of workers.

More than 10% of the steel plates used by Blue Whale this time are super thick steel plates. For Zhao Jingfu, he is familiar with the structural form of the steel plate in advance and has some control over possible problems during the welding process. In addition, the composition design of marine steel can be adjusted in time based on future welding performance to strengthen the body and welding strength of marine steel.

Fuhai Group and Hongan Steel discussed the research and development of F-class ultra-high-strength marine engineering steels in full swing at Hongan Steel Materials Research Institute.

Zhang Yujie submitted a basic force analysis drawing for the Blue Whale to Han Fangyun, pointing out that the F-class ultra-high-strength marine steel developed this time is used in the main force-bearing parts of the Blue Whale column and upper platform, and has been under tremendous pressure.

According to the requirements of fatigue, structure and other aspects, F-grade ultra-high strength marine steel needs to reach at least 690mpa or above, and must have excellent low-temperature toughness, welding performance and corrosion and crack resistance, and the thickness specifications need to be 100mm.

This product is named f690 super thick marine board.

Han Fangyun looked at the detailed stress analysis table in her hand and understood that the R&D task she took on this will be one of the biggest challenges she has been in the metallurgical industry.

"General Engineer Zhang, don't worry, our Hongan Steel will do our best to carry out research and development work day and night, and bring out qualified products within the specified time limit!"

Han Fangyun's reassurance did not make Zhang Yunjie feel safe. He knew that before the steel plate appeared in front of him, all the guarantees and promises were empty talk, but Hongan Steel's attitude still made him very pleased. After all, it was not an easy task to complete the research and development of a high-tech variety in such a short time.

"Okay, thank you Director Han for your hard work. This is Comrade Zhao Jingfu, a senior technician of our Fuhai Group. He is our welding expert. Although his understanding of materials cannot be comparable to that of Hong'an Steel's colleagues, he is responsible for the heavy welding of this offshore engineering. Therefore, Director Han must seriously consider his ideas and opinions at that time!"

Zhang Yujie knows that he doesn't have to worry about the quality of materials. Hongan Steel itself is a special steel production base, and its quality is absolutely guaranteed. What needs to be considered now is future welding issues. After all, the F-class ultra-high-strength marine steel developed this time is not only the steel plate itself has extremely high strength, but also has another feature, that is, its super-thickness.

Extra-thick steel plates over 100 mm are a test of welding capabilities. They tried every means to weld the materials they provided before. If they participated in the welding work in advance during the research and development process, it will be a great help for timely adjustment of the material alloy composition and strengthening the final welding effect, and will also be a great improvement for future welding work.

Zhao Jingfu was listening carefully to the understanding and analysis of the materials between the two parties. Seeing that Zhang Yujie mentioned him, he hurriedly stood up.

"All the experienced teachers here are all experienced teachers. I am a young student. In my future cooperation, I would like to give you some advice and make this series of marine plates a world-class!"

"That's right, if we want to do it, we must be first-class! I agree with Master Zhao's idea very much!" Han Fangyun immediately stated, "When we develop materials, we need the addition of practical operators like Master Zhao to encourage us to improve the material characteristics and better serve everyone!"

The two sides reached a consensus in a pleasant atmosphere, that is, to do their best to complete this material development task within the time frame to meet the needs of the Blue Whale.

After the consultation, Zhang Yujie with Fuhai Group's troops evacuated, leaving only Zhao Jingfu in Hong'an Steel responsible for assisting in the development of F-class ultra-high-strength marine engineering boards.

Before leaving, Wei Yuhui selected some reference books that Zhao Jingfu could use and left for him.

"Precautions for taking care of your health!" Wei Yuhui said with a smile, "You can't abuse even if you have capital!"

Zhao Jingfu smiled and compared her biceps to her, which made Wei Yuhui giggle for a long time.

Looking at the departure of the Fuhai Group team, Zhao Jingfu was also a little sad, but more lonely. Fortunately, Hong'an Steel also knew about this situation and provided him with more convenient living conditions.

Zhao Jingfu also knew that he was not here to enjoy the happiness when he stayed in Hong'an Steel. If he did not complete the research and development of F-level ultra-high-strength offshore boards within the specified time limit, he might have become the sinner of Fuhai Group.

"Director Han, I plan to move to your Iron and Steel Research Institute, so it is convenient for communication. What do you think?" Zhao Jingfu immediately found Han Fangyun.

Han Fangyun looked at Zhao Jingfu in surprise. In her heart, this young man from the coastal area would definitely dislike Hong'an Steel's environment, so he arranged for him to live in Hong'an Steel's hotel.

Although he came to help, most of the technical points were listed in the consultation minutes. As long as you ensure that there are no problems in the general direction, you can basically check the test records every day, and this kind of life is not a grievance.

He didn't expect that Zhao Jingfu took the initiative to ask to live in the Iron and Steel Research Institute. No matter how good the treatment is in that place, it will definitely not be as easy as the hotel's life!

"Director Han, the time given by the company is urgent, so I have to be a little concerned. After all, the Whale Dream Project embodies all of us Fuhai people's desire for the future and the will to innovate independently. If any accident occurs, I really can't explain it!"

Han Fangyun understood Zhao Jingfu's thoughts, and she also knew the importance of the marine board to the Blue Whale. This can be seen from Zhang Yujie's personal leadership.

"You can come to the research institute, but the hardware facilities here may not be as good as hotels. You have to take care of this!" Han Fangyun said with a smile.

Zhao Jingfu looked indifferent, "What's the matter? When I was in a shipyard, I encountered welding tasks. I lived on the scene all day and night, and even lay in the steel pipe to rest. There is always a bed in the research institute, right?"
