Military Heavy

Chapter 431 Failed

Liu Chuandong looked at Yang Fan.

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

Hope also rose in the hearts of Feng Wangdong and Sun Baoguo.

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

Liu Chuandong warned: "Old Sun, you must be careful, show your skills, and make it a one-time success without any problems."

He is also very hopeful of success.

Master Yang said that if the welding quality of this welding consumable is acceptable, it will make him a supplier of the 054 ship in the future, and he will be able to successfully open up the military industry market.

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

So long and so thin.

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

Everyone stood by the side, their hearts were fully raised, and they didn't even dare to breathe out, for fear of welding failure.

The place was quiet.

Only the slight sound of Master Sun's work.

He first looked at the things to be welded, and then looked at the welding process drawings. After he had an idea, he picked up the electric soldering iron and started to weld the first pin.

The whole process is very slow and very focused.

Yang Fan watched his welding from the side, and the scene when he saw Zhong Lihong welding could not help appearing in his mind, and he couldn't help making comparisons.

Obviously, Zhong Lihong's movements are much more skilled and faster, and she is full of confidence.And the master Sun in front of him seemed to have solid basic skills and standard movements, but there seemed to be a pressure and his movements were much slower.

When the first pin was finally soldered, he paused for a moment.

Everyone involuntarily took two steps forward and looked at it carefully. Sun Baoguo took over the joint and looked at it very carefully. The welding technician in charge even stepped forward, looking at it again and again.

"Well, the welding is not bad, and the quality is acceptable." The technician in charge said so.

Immediately, everyone felt relieved.

At least the beginning was relatively smooth, the first pin was welded qualified, and I saw hope all at once.

Welding follows.

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

Second root, third root, third root.
This cable connector has a total of 22 pins, which are very small and must be soldered one by one. As the number of soldered pins gradually increases, the difficulty becomes more and more difficult.

At the beginning, when the first pin was welded, the people of Dongjiang Shipyard seemed to see hope. Now, seeing that the number of pins increased and the difficulty increased, they were gradually sweating in their hearts.

The scene has been very quiet, no one made a sound.

People such as Feng Wangdong and Sun Baoguo, who were originally suspended, relaxed a little bit, but now they are suspended again.

After three or four 10 minutes, the soldering was finally completed. There are 22 pins in total, one of which is quite a few, and it looks pretty good.

But in the end, I don't know yet. It needs to be inspected by professionals, and the technician in charge will inspect it immediately.

After two or three minutes, he shook his head gently and reported: "Leaders, the welding is unqualified. There are a few weak welds, which will affect the electrical conductivity. In addition, there are two pins that are not welded properly."

There is more than one problem.

Some problems are related to welding experience. After all, Mr. Zhao has never welded such a thing. Some problems are related to welding materials, such as virtual welding, lack of penetration, compatibility of welding materials and pins Not up to standard etc.

Can not be done!
Welding was unsuccessful.

The entire scene was suddenly filled with an atmosphere of disappointment. Liu Chuandong was originally full of confidence, but suddenly he seemed a little embarrassed.

Yang Fan patted him on the shoulder lightly, and comforted him: "Mr. Liu, don't blame yourself too much. After all, this is the first time welding, and you have never encountered such a material as the pin."

Liu Chuandong glanced at Yang Fan gratefully. He originally thought that Yang Fan would be very dissatisfied if things were messed up.

But Yang Fan didn't, but comforted and encouraged him.

As for Feng Wangdong and Sun Baoguo, they were extremely disappointed, their hopes were shattered, their life-saving straw was gone, and they felt very uncomfortable.

After a long time, Feng Wangdong, who was the leader, represented Dongjiang Shipyard and thanked: "Master Yang, you have bothered. Although it didn't work, we still have to thank you."

Yang Fan seemed a little embarrassed, and said apologetically, "Oh, it's just that it didn't work out, and we'll have to continue trying to find a way."

Lu Huaqiang was very smart. Seeing that the atmosphere at the scene was not right and the leaders were not in a good mood, he quietly made a face to Liu Chuandong.

Then, Lu Huaqiang said: "Mr. Yang, if the matter is not completed, there is no need for us to stay here anymore. Lao Liu and I will go back first."

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

Lu Huaqiang, Liu Chuandong and Master Sun left.

After they left, everyone also left here. Feng Wangdong still had something to do, so he hugged Yang Fan, "Master Yang, I have something to do, so let's leave first."

After finishing speaking, he told Sun Baoguo: "Mr. Sun, treat Mr. Yang well."

Yang Fan hurriedly said: "Mr. Feng, go get busy. Mr. Sun and I happened to have another chat about welding materials."

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

Sun Baoguo personally brewed two cups of hot tea, one for each person, and sat down on the sofa, and said worriedly: "General Master Yang, it's impossible to go on like this."

Yang Fan nodded in agreement, "Well, our time is limited, and every day of delay means a day wasted. If the delay continues like this, whether the ship can be delivered on time becomes a big problem."

The two chatted for a while, and Sun Baoguo said, "Master Yang, can you change the design and change these cables into other models?"

If it can be changed to other types of cables, then there is no need to weld the joints, and the problem of not having imported welding materials will be solved.

However, Yang Fan shook his head lightly.

This definitely won't work.

More than half of the cables are of this type, and the latter are replaced with other cables. Two different cables are mixed together, which is a bit different, and it will also affect the performance of the entire ship.

Seeing Yang Fan deny the proposal, Sun Baoguo sighed heavily.

He was really helpless, helpless.

Yang Fan understood his feelings and comforted him, and finally left Dongjiang Shipyard full of pressure. After returning to Donghai Institute, he was still thinking about importing welding consumables.

Two days later.

There is still no progress in the Dongjiang Shipyard, and the headquarters also needs time. Therefore, the outfitting work of the first ship has stalled again.

The leadership of the entire Dongjiang Shipyard was under tremendous pressure, and they were almost out of breath. Some people thought pessimistically, do they really have to wait like this for more than ten days, or even twenty days, until the general headquarters came out of nowhere? Will foreign countries bring back the imported welding consumables needed?

Zhong Lihong and other female workers who were in charge of welding the cable joints also stopped completely, and instead of boarding the ship to outfit the cables, they stayed in the female workers' lounge.

This has been the case for several days.

Some female workers were cracking melon seeds, while others were knitting sweaters. As the squad leader, Zhong Lihong neither cracked sunflower seeds nor knit sweaters, but was extremely anxious.

There is no imported welding consumables, the cable joints cannot be welded, and the outfitting work has come to a standstill one after another. She sees it in her eyes and concentrates on it in her heart.

In the end, she held back and began to think of a way. She kept experimenting alone, trying to replace it with other brands of welding consumables, but unfortunately, it always failed.

Donghai 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 basis of the original design, and appropriate improvements have been made, especially the utilization rate of localized spare parts has been increased.

While watching seriously, the big brother on the desk rang loudly.

People from Donghai Institute usually make office calls, and those who are very familiar with Yang Fan also make office calls, because they know that Yang Fan should be at work at this time, maybe in the office.

After answering the phone, Yang Fan was slightly surprised that it was Liu Chuandong who called.
