Zhang Yujie tried his best to downplay the situation, but Zhao Jingfu still suddenly felt that the heavy responsibility on his shoulders was so arduous, like a Mount Tai weighing on his head, and his heart, which had been calm and composed in the face of countless arduous and complex welding tasks, began to beat wildly.
Yes, if the F690 cannot pass the low-temperature CTOD test, the Blue Whale cannot be built. This will bring a series of effects that are difficult to predict.
Zhang Yujie also felt Zhao Jingfu's uneasiness. He understood that such a heavy burden fell on this ordinary welder. Even if he was a master of welding and a senior technician, he would probably be at a loss when facing this situation.
"Don't worry, the group company has also begun to conduct various calculations and studies on the experimental data of F690. You are not fighting alone, nor are you a team. The experimental scientific research team is fighting. Behind you are Fengyang Shipyard and all Fuhai people.
backing!"
"I understand!" Zhao Jingfu nodded solemnly.
Zhang Yujie is a man of action. He then carefully read Zhao Jingfu's f690 welding data several times. After reading it for a long time, he did not find any connection.
As reported by Zhao Jingfu, the appearance of pores is not only related to voltage, current and temperature, but may also be related to special changes in solder and f690 at high temperatures.
After all, f690 and solder are both new materials, and with the thickness of f690 exceeding 100 mm, everything is unknown.
This situation is very complex, and a slight change in data may cause unpredictable consequences.
"The situation is indeed complicated!" Zhang Yujie picked up the data in his hand again and shook his head slightly while looking at it.
Even though he was a veteran in the field of offshore engineering equipment for decades, he seemed a little helpless in the face of this situation.
"Yes, Mr. Zhang, we have experimented hundreds of times, adjusting the current, voltage and temperature, hoping to find the specific reason for the appearance of the pores, but now you can see it too!" Zhao Jingfu sighed and shook his head,
"No progress so far!"
"Who said there is no progress at all?" Zhang Yujie pointed to the test report on the table, and then pointed to the waste materials in the test site, "See, this is progress. As long as we eliminate these unfavorable factors, we will be close to the dawn of victory.
It’s getting closer!”
Hearing what Zhang Yujie said, Zhao Jingfu's nervous mood gradually calmed down. It turned out that even the chief engineer was helpless in the face of such an extremely complicated situation. It was natural for him, a welder, to not be able to find the cause.
While the two were talking about the test, the workers in the test team also went to work one after another. Everyone saw Zhao Jingfu discussing the issue of air holes in a low voice with a middle-aged man. They thought it was a staff member sent by the shipyard's technical department, so they thought it was a worker sent by the shipyard's technical department.
They immediately gathered around and started chatting.
It was too late for Zhao Jingfu to stop him, but Zhang Yujie didn't care. He listened carefully to the thoughts of these workers. Although what the workers said was what he expected, he still felt that these grassroots workers were not as expected as they were.
, just focused on working without any understanding of the entire engineering principle.
He couldn't help but look at Zhao Jingfu. It was said that a team led by a raging army, a den of bears, and a lion would be able to gallop across the grassland, while a team led by a sheep would only end up being eaten.
Zhao Jingfu not only has outstanding strength, but the team he leads is also unique.
"Okay, have you finished sharing your thoughts and opinions?" At the beginning, the workers talked about technical issues. After they finished talking about the problems, they started to go a little out of line.
Normally, it would be a joke among the workers, but this is the chief engineer. If some words get out, I am afraid that Mr. Hu of the shipyard will not look good.
"Hurry up and get to work. Mr. Zhang has important things to do and I don't have time to talk nonsense with you guys!"
As soon as Zhao Jingfu said these words, the workers who were still laughing and joking around him suddenly looked at each other.
Chief engineer?
"Squad leader, where is the chief engineer?" For the workers, the chief engineer is already the most skilled person among them, and it is also a goal that they will never achieve in their lifetime.
"Nonsense, haven't you seen the chief engineer of our shipyard?" Zhao Jingfu cursed, "This is chief engineer Zhang of our Fuhai Group, the commander-in-chief of the Whale Dream Project!"
Chief Engineer Zhang Yujie, Commander-in-Chief of Whale Dream Project!
When the workers heard this, they immediately didn't dare to say anything. Then you looked at me and I looked at you, as if you felt the danger was coming.
"Everyone's ideas and suggestions are very good. I have also written them down and let the technical department comprehensively verify them when I get back. Thank you very much!"
"Okay, everyone, let's continue working. We must completely find the cause of the f690's pores!"
When the workers saw this, they immediately dispersed and immediately began to continue the welding test. For a time, the entire test site was filled with smoke and the heat rose rapidly. Even though there were more than a dozen large fans, it was of no avail.
Zhang Yujie looked at the heat wave in front of him and couldn't help but sigh in his heart. The workers in Fuhai are the cutest and most dedicated. Everyone said that the work is tiring, and this is the real hard job!
"Master Zhao, I will also contact Hong'an Steel after I return and let them put forward some feasible suggestions as much as possible. In addition, the company and the shipyard will also strengthen cooperation. You and the inspection department will work together to produce the data, and then let them
The technical department will propose corresponding test plans and fully support your work, which is better than finding a needle in a haystack like you!"
"Okay, with the full support of the technical department, I believe that the problem with the f690 will be found soon!" Although Zhao Jingfu was not sure, with so much departmental support, he felt relieved. It was better than himself and
The inspection department is much better off working alone.
After Zhang Yujie returned, he immediately established a research team for the F690 low-temperature CTOD test. He served as the team leader, and Hu Yufeng, general manager of Fengyang Shipyard, served as the deputy team leader. Technical personnel from Fuhai Group and Fengyang Shipyard's technical department were gathered to tackle key problems and conduct all tests.
Data are analyzed and tested.
Subsequently, Hong'an Steel also sent the latest news. After Director Han Fangyun mobilized R&D personnel to conduct a comprehensive analysis and study, no abnormality was found in f690. It was recommended that the current and voltage be effectively controlled during welding operations, and it was proposed
Corresponding current, voltage and temperature control ranges.
For Zhao Jingfu, this suggestion can greatly reduce the intensity and number of tests, which is excellent news. However, even so, Zhao Jingfu still faces an arduous task.
