Liu Chuandong looked at Yang Fan.

Yang Fan understood what he meant and said loudly: "Then start welding, hoping it will succeed."

Hope also arose in Feng Wangdong and Sun Baoguo's hearts.

The worker sat in front of the welding workbench, and the cable connectors were also placed on the workbench, and everything was complete.

Liu Chuandong reminded: "Old Sun, you must be careful and show your skills. You must succeed at one time. Never have problems."

He also hopes to succeed.

Chief Engineer Yang said that if the welding quality of this kind of welding material is good, it will make him a supplier of ship 054 in the future and he can successfully open up the military industry market.

Master Sun nodded and sat in front of the workbench to start work. First, he looked at the joints to be welded, and needed to weld the slender, golden pins.

So long and so thin.

This material seems to be a little different. I may have never seen it before, so you can't be careless, you must be careful. Master Sun thought so.

Everyone stood beside him, and their hearts were fully raised. They didn't even dare to let out a moment of excitement, for fear of failure of welding.

The scene was quiet.

Only Master Sun's slight voices made by his work.

He first looked at the things he wanted to solder, then looked at the welding process drawings, and after he knew it, he picked up the soldering iron and began to solder the first pin.

The whole process was very slow and very focused.

Yang Fan looked at his welding next to him, and the scene of seeing Zhong Lihong welding appeared in his mind, and he was involuntarily comparing it.

Obviously, Zhong Lihong's movements are much more skillful and faster, and she exudes a sense of confidence all over her body. The Master Sun in front of her looks solid in basic skills and has very standard movements, but it seems to be filled with pressure and has much slower movements.

The first pin was finally soldered, and he stopped temporarily.

Everyone couldn't help but take two steps forward and looked at it seriously. Sun Baoguo took the joint and looked at it very carefully. The welding supervisor technician even moved forward and looked again and again.

"Well, the welding is pretty good, the quality is qualified," said the supervisor technician.

Suddenly, everyone felt much more relieved.

At least the beginning was relatively smooth. The first pin was soldered and I saw hope all at once.

The welding is then carried out.

Master Sun was as focused as ever, very serious, and his movements were still relatively slow and his speed was not fast at all.

The second, the third, the third...

There are 22 pins in total in this cable connector, which are very small and must be welded one by one. As the number of pins soldered gradually increases, the more difficult it becomes.

At the beginning, the first pin was soldered, and the people at Dongjiang Shipyard seemed to see hope. Now, seeing the number of pins increased and the difficulty increased, I gradually felt a little sweat in my heart.

The scene was always very quiet and no one made any noise.

People like Feng Wangdong, Sun Baoguo and others, whose hearts were originally hanging a little, but now they are hanging again.

It took a full 30 to 40 minutes to finally be soldered. There were 22 pins in total, a lot of each, and it looked pretty good.

But I don’t know what happened. I need to go through a professional inspection, and the supervisor and technician immediately checked.

Two or three minutes later, he shook his head gently and reported: "Dear leaders, the welding is not qualified, and there are several false weldings that will affect the conductivity. In addition, there are two pins that are not standardized for welding..."

There are more than one problem.

Some problems are related to welding experience. After all, Master Zhao has never welded such things, and some problems are related to welding materials, such as virtual welding, no penetration, and the fusion between the welding materials and pins does not meet the standards.

No!

The welding was not successful.

The whole scene was filled with a disappointment all of a sudden. Liu Chuandong was originally full of confidence, but suddenly seemed a little embarrassed.

Yang Fan gently patted his shoulder and comforted him: "Mr. Liu, don't blame yourself too much. After all, it's the first time we soldering. You have never encountered such material as pin insertion."

Liu Chuandong looked at Yang Fan gratefully. He originally thought that if the matter was messed up, Yang Fan would be very dissatisfied. Even if he was not angry, he would at least show his face.

But Yang Fan did not, but comforted and encouraged him.

As for Feng Wangdong and Sun Baoguo, they were extremely disappointed. The hope in their hearts was shattered and the life-saving straw was gone. They felt very uncomfortable.

After a long time, Feng Wangdong, as the top leader, expressed his gratitude to Dongjiang Shipyard: "Chief Teacher Yang, you have troubled. Although you have not succeeded, we still want to thank you."

Yang Fan seemed a little embarrassed and said with apologies: "Oh, it's just that it didn't work out. We have to continue to think of another solution next."

Lu Huaqiang was very smart. Seeing that the atmosphere on the scene was wrong, the leaders were in a bad mood, he quietly gave Liu Chuandong a look.

Then, Lu Huaqiang said: "Mr. Yang, if the matter is not completed, we don't need to stay here anymore. Lao Liu and I will go back first."

Yang Fan said: "Yes, you guys go back first."

Lu Huaqiang, Liu Chuandong and Master Sun left.

After they left, everyone left here. Feng Wangdong still had affairs and hugged Yang Fan, "Chief Yang, I have something to do, leave first."

After saying that, he urged Sun Bao Guodao: "Mr. Sun, please entertain Chief Secretary Yang."

Yang Fan hurriedly said, "Mr. Feng, go and do your business. Mr. Sun and I will talk about welding materials again."

After watching Feng Wangdong leave, at the invitation of Sun Baoguo, Yang Fan entered Sun Baoguo's office and sat down on the sofa.

Sun Baoguo personally made two cups of hot tea, one cup for each person, and also sat down on the sofa and said worriedly: "Chief Yang, this won't work."

Yang Fan nodded in agreement, "Well, our time is limited, and every day we drag it means a waste of one day. If we drag it like this, can we deliver the ship on schedule? This has become a big problem."

After chatting for a while, Sun Baoguodao said: "Chief Yang, can you change the design and change these cables into other models."

If it can be changed to other models of cables, there is no need to weld the joints, and the problem of no imported welding materials will be solved.

But, Yang Fan shook his head gently.

This definitely doesn't work.

More than half of the cables are of this model, and the ones behind are changed to other cables. Two different cables are mixed together, which is a bit different, and will also have an impact on the performance of the entire ship.

Seeing Yang Fan denying this proposal, Sun Baoguo sighed heavily.

He really had no choice but to be helpless.

Yang Fan understood his mood and comforted him. Finally, he left Dongjiang Shipyard with pressure. After returning to Donghai Institute, he was still thinking about importing welding materials.

.........

Two days later.

There is still no progress in the Dongjiang Shipyard, and the General Command also needs time, so part of the outfitting work of the first ship has stopped.

The leadership of the entire Dongjiang Shipyard was under great pressure and almost breathless. Some people thought pessimistically, would they really have to wait like this and wait for more than ten days, or even twenty days, until the General Command brought back the imported welding materials they needed from abroad?

Zhong Lihong and several other female workers in charge of welding cable joints also stopped completely and did not board the ship to perform cable fittings, but stayed in the female workers' rest room.

This has been happening for several days.

Some female workers were eating melon seeds, while others were just knitting sweaters. As the squad leader, Zhong Lihong neither ate melon seeds nor knitted sweaters, but was extremely anxious.

Without imported welding materials, cable joints could not be welded, and the outfit work gradually stopped one after another. She saw it and kept it in her heart.

Finally, she resisted and began to think of a solution. She was experimenting non-stop and trying to replace it with other grades of welding materials, but unfortunately, it was a failure.

East China Sea Ship Design Institute.

Yang Fan is looking at a design drawing of the 054 ship. This new design drawing has been partially improved on the original basis and has been appropriately improved, especially improving the use rate of domestic spare parts.

While watching seriously, the big brother who was on the desk rang out loud.

If you are from Donghai Institute, you will usually call the office. If you are a person who is very familiar with Yang Fan, you will also call the office because they know that Yang Fan should be at work at this time, maybe in the office.
