Several eyes were all focused on Yang Fan.

The scene suddenly became extremely quiet!

After a few seconds, Chen Shaohua asked in a trembling voice: "You... do you really have a way, can you... solve the problem of welding cracks?"

He has a good understanding of Yang Fan.

Knowing that Yang Fan is steady and does not brag, he would definitely not say this if he was not sure. Because of understanding this, hope suddenly arose in his heart, and even his words were filled with tremolo.

Solving the current problem of welding cracks is something he dreamed of.

Last night, for this problem, he tossed and turned and couldn't fall asleep. He was under great pressure, anxious and extremely anxious.

Now, it seems like I see hope all of a sudden!

Yang Fan nodded gently and said confidently: "I think I have found the root of the problem, we will know it after a try."

Really!

Very good!

God bless you!

In an instant, Chen Shaohua was extremely surprised and excited. He almost held Yang Fan's hand tightly, hoping to try how to solve the problem of welding cracks.

"Then try it quickly." Chen Shaohua waved.

In order to weld the cracks, he racked his brains and spent countless nights. Wu Mingze also wanted to know where the problem lies.

"Director Yang, come and guide you, I will weld whatever you say." Wu Mingze said.

Yang Fan nodded and pointed to the welding pad and said, "I think the problem lies in the welding pad. I looked at your welding carefully and thought that this pad is not well-paid. The gap between the pad and the welded steel plate is relatively large, so it must be tightly padded, and it is best not to have any gaps."

Is it really a problem with the pad?

Wu Mingze thought something.

He had also suspected the pads, but after fiddling with them for a long time and personally welded the test pieces, there were still welding cracks. As for the pads, they had to be tightly padded and there was no gap, he had never done it specifically like this.

Cao Ping next to him obviously had doubts about this and reminded: "Director Yang, the pad is not necessary when welding. There are some steels, and weld it well when we pull the pad apart. I think it should not be much different if we use the pad or not when weld this new steel grade."

Yang Fan shook his head gently.

If it were before, he would not have doubted the inconspicuous pad. Now, he finally remembered how welding cracks occurred and how to solve them at the beginning of the construction of the first ship of the 052 ship. The problem lies in this pad.

Chen Shaohua obviously trusted Yang Fan very much and decided to say, "Don't say so much, Master Wu, just try welding a test piece as Director Yang said."

"Can."

Wu Mingze nodded in agreement, and he really wanted to try it out. Is the problem really lies in the pads. So he arranged the test pieces according to Yang Fan's requirements and used the pads to tightly pad them. It was confirmed that it was very tight and there was almost no gap, and then he picked up the welding gun.

Sizzle...

The sound of welding sounded again, the arc shining, very bright and dazzling.

The scene was very quiet, no one spoke or spoke.

After a while, Wu Mingze finished welding, put down the welding gun, put down the welding mask, and looked at the welded specimen.

During the welding process just now, he seemed to have a slight feeling, as if it was different from before, and a strong hope quickly rose in his heart.

After a while, after the test piece had cooled down almost, Wu Mingze picked up the test piece wearing gloves and looked carefully under the light.

Chen Shaohua, Yang Fan and Cao Ping all came over, focusing all their eyes on this specimen, and carefully looking at the welds on it.

The welds are still very beautiful, with standard fish scale welding.

He is worthy of being the welding king of Donghai Factory!

This level is really extraordinary.

After watching for a long time, the expression of happiness appeared on the faces of several people. Cao Ping even shouted loudly, "There are no cracks, but there are no cracks. It's amazing!"

Just moving the pad!

It's just a tight cushion.

The effect is so good, and it will be immediate!

The welding crack that had been around forever disappeared.

Chen Shaohua smiled, smiling happily.

Wu Mingze also breathed a long sigh of relief.

Yang Fan suggested, "To be safe, we will use the method just now to weld two more test pieces to see if they are all the same."

"Yes, yes, weld two more specimens." Chen Shaohua strongly agreed.

Soon, Wu Mingze picked up the welding gun again. It didn't take long to use the two test pieces, and everyone looked at the two test pieces carefully under the light.

"There are still no cracks found!"

“It’s so unbelievable!”

“…”

After a burst of joy and excitement, everyone's heart was at least halfway down. In order to be more secure, Yang Fan suggested: "Please take these three welded specimens, let's go to the testing laboratory and have a good test."

"Yes, yes." Chen Shaohua raised his hands to agree again.

So, the four of them took these three test pieces to the testing laboratory and started a series of professional testing.

Passed the lift test!

Passed the bending inspection!

Passed the microscopic test....

A series of professional tests have passed all!

Suddenly, the testing laboratory cheered, especially the technicians involved in the testing, jumped and shouted, and seemed extremely excited.

As for Chen Shaohua, no one is happier than him. The stone pressing in his heart completely disappeared and the welding was qualified, which means that the obstacle had been successfully moved. Next, the sectional manufacturing workshop can be welded and the first ship can be manufactured in sections.

All his eyebrows were stretched out. He had grown much older, but suddenly he seemed to be younger again. His originally gray face gradually became rosy.

He was full of red and full of energy!

Yang Fan also smiled happily, and the problem of welding cracks was finally solved.

The news spread very quickly.

When Lu Guodong received the call, he put down everything at hand without saying a word and arrived at the testing laboratory as quickly as possible.

He held Yang Fan's hand tightly and said gratefully: "Comrade Yang Fan, on behalf of Donghai Shipyard, I would like to express my gratitude to you. If it weren't for you, we wouldn't know when we would solve the problem of welding cracks."

Faced with the thanks from the top leader of the Donghai Shipyard, Yang Fan still seemed very modest.

"Yan is so heavy, I just made some suggestions. It's the one who passed the welding process by Master Wu Mingze."

"Comrade Yang Fan, you are too modest."

News has spread almost throughout the Donghai Shipyard, not only in segmented manufacturing workshops, but also in the technical system of the Donghai Factory.

"Director Yang is so awesome!"

"Yes, it's really a bit of a sudden!"

"The problem of welding cracks has not been solved for so long, and he actually solved them. I can't believe it."

“……”

Donghai Factory was discussing this matter hotly, and many people were full of admiration and gratitude for Yang Fan in their words.

At noon, Lu Guodong warmly invited Yang Fan on behalf of the Donghai Shipyard. Almost all the senior executives of the entire Donghai Shipyard attended the luncheon.

This treatment, this specification!

It is estimated that besides Yang Fan, only those leaders who came to inspect and investigate may have it.

.........

Capital.

052 Ship General Command.

Commander-in-chief Huang Keping sat in the office and read several documents and reports. He thought to himself that the Donghai Shipyard encountered a problem of welding cracking, and this problem has not been solved. I don’t know how long it will bother them.

On the vast sea with a huge weather, a small welding flaw can lead to the tragedy of ships and people being killed. Huang Keping is very worried about this.

After thinking about it, I thought in my heart that I would take time to go to the East China Sea Shipyard to cheer them up and not let their morale be depressed.

Just as he was thinking about this, there was a knock on the door outside the office door, and his secretary walked in happily, as if there was a huge happy event.

As a secretary, of course I know what the leader thinks.

He knew very well that Commander Huang had been paying attention to the construction of the first ship, especially he was very worried about the welding cracking problems encountered by the East China Sea shipyard.

Now, the problem has been solved!

As soon as he came in, he reported very excitedly: "Shou Chang, the problem of the Donghai Shipyard has been solved. Director Lu Guodong personally called the General Command to report."

What!
