"There are no problems with the overall design. Then it depends on the construction. As long as the quality is ensured during construction," Qin Tao said, "Especially the precision of the welding, there cannot be any problems. This project is led by Cong Gong
Take responsibility."
Cong Ju nodded: "Well, I will work hard and cooperate with the foreign supervisors."
This liquefied gas ship also has a unique feature. It is the first ship shipped by Mingzhou Shipyard to a foreign shipowner. There are many exemption clauses in the contract, so foreign shipowners are definitely worried. It must be
The most capable supervisor will be sent over, and it is not certain whether it will be Carrasco.
The ship was handed over to Cong Ju, who took on this responsibility without hesitation. The design was completed, and the next main task was welding. Speaking of which, she was very good at it.
"Gong Cong will be busy again in the future, but the factory will take good care of the employees' personal families. Gong Zhou will not have too important tasks. He can go to get off work on time and have enough time to pick up and drop off his children." Qin Tao said.
Cong Ju nodded: "Thank you."
"What a pity, this kind of ship waste is too serious." Yang Dawei was already sighing at the side.
Although the design is good, look at how much space is wasted under the five big balls? It would be great if these could continue to be loaded.
"Yes, so this kind of ship is a transitional one. We will still have to study membrane-type ships made of Invar steel in the future." Qin Tao said, "Of course, this will have to wait until our shipyard develops to a certain extent."
Now, it's just the beginning. They are the first in China to eat crabs, and they will become leaders in this industry in the future!
Moreover, after that time, the country will also issue guidance on domestically built ships and domestically transported goods. The natural gas needed by the motherland can only be transported by liquefied gas ships produced by the motherland itself. By that time, the demand for liquefied gas ships will be even greater.
.
Therefore, in the later stage, we must overcome the difficulties of natural gas ships built by advanced Invar Steel. Moreover, all technologies are our own. If we import technology from abroad at a high price and have to pay expensive patent fees, it is not worth it.
"Ding, ring, ring." At this moment, the phone in the conference room rang. Qin Tao picked up the phone and looked at the four-digit extension number inside, feeling a little strange.
"Hey, what's going on? What? Let's go over and take a look right away."
Putting down the phone, Qin Tao had a serious expression on his face.
"Qin Gong, what happened?" Cong Ju asked nervously.
"The welding workshop reported that the quality of the weld seam on the third aluminum alloy can being welded was not up to standard."
"What?" Cong Ju immediately ran out in a gust of wind.
The first aluminum alloy can was their trial product and was a complete success. The second aluminum alloy can was welded by the master craftsmen without Cong Ju being present. There was no problem and it is now being welded.
The one welded was the third one. Who would have thought that the quality was not up to par?
The first batch requires at least five aluminum alloy tanks. If the delivery time is delayed due to unqualified welding of these aluminum alloy tanks, they will need to compensate. What is more serious is that their reputation will be damaged and they will no longer be able to undertake natural gas ships in the future.
contract.
As the person in charge of this project, Cong Ju is very anxious.
Despite her small stature, she ran quite fast. She was the first to return to the welding workshop. She looked at the air holes in the welds and looked extremely ugly.
"Gong Cong, is there something wrong with the machine made by the islanders?" A master said: "The islanders are not kind, maybe there is something weird in the machine."
"That's right, if it doesn't work, we will weld it manually. This automatic equipment is just unreliable."
Amid everyone's discussion, Cong Ju looked at the weld carefully. There were many pores on the weld that should have been smooth. How could this happen?
Welding is a complex process. The liquid inside the molten pool cools to form a strong weld. Generally speaking, there are few bubbles inside the molten metal, and such dense pores will not be formed.
Qin Tao and Yang Dawei also arrived.
Qin Tao frowned, looked at the welds, then looked at the surrounding environment, and then said: "It should be the influence of air humidity."
"Air humidity?"
"Yes, the humidity below 60% is the best environment for aluminum alloy welding. If the humidity exceeds 70%, supersaturated hydrogen will appear in the molten pool during the welding process, and the weld will condense at the moment
, forming a large number of bubbles, rising in the liquid-solid two-phase molten pool, turning from bubbles into pores, and exposed from the surface, so now you can see that the surface of the weld is pores, but inside, there should be bubbles one by one."
"I really didn't expect that aluminum alloy welding is also related to the weather. It's time to enter the rainy season. So in our workshop, we can't weld a qualified aluminum alloy can?" The old worker's tone was full of disappointment.
.
"Yes, it should be a problem of humidity." Cong Ju also confirmed Qin Tao's analysis.
At the beginning, Cong Ju was led astray by everyone. Everyone was complaining about the automatic welding equipment, so she also suspected that there was a problem with the welding equipment. After Qin Tao's analysis, she realized that it was true during the previous training.
I've heard of it, but I didn't meet it that often, so I forgot about it.
"Then what's next? We can't just watch God work, can we?"
"Of course not." Qin Tao said: "We immediately purchased a large number of industrial air conditioning equipment to turn the entire welding workshop into a constant temperature and humidity system."
"What?"
Everyone was stunned again.
In this day and age, it would be nice to have a fan in hot weather, but air conditioning is impossible. At this time, Qin Tao actually said that he wanted to purchase an air conditioner for this place. Look at the space inside, how much air conditioning is enough?
And, how much electricity does that thing cost?
As a result, how much will their production costs increase?
"Qin Gong, does it have to be like this?" Even Cong Ju had some doubts.
Workers in this era can endure hardship. In the hot summer, they wear thick work clothes and climb to dangerous places to weld. After the work is done, they are all wet and no one complains. Who would ask for the installation of air conditioning equipment?
"Yes, it is necessary." Qin Tao said: "Now, we are only producing aluminum alloy MOSS cans. In the future, after using Invar steel, we will need to produce them in a workshop with constant temperature and humidity. We will not be able to wait for a while.
Weeks may turn expensive products into scrap. These are necessary, otherwise why would this kind of ship be sold at a high price?”
Don’t be afraid of increased costs, we sell them expensively!
What should be invested must be invested. In the past, the practice of doing things if conditions were met and doing things even if conditions were not created has become outdated. They must have a qualified working environment.
"Okay, then we will stop work first and conduct a strict sealing operation in the workshop before the equipment is installed in place." Cong Ju said.
…
Mingzhou Shipbuilding Industry Affiliated Primary School.
The school bell rang, and the campus immediately became lively. Primary school students lined up and walked outside. There was already a circle of parents outside.
"Daddy, daddy!" Lili shouted loudly, and then ran towards Zhou Yongfei.
"Lili, come, sit in the back." Zhou Yongfei carried Lili onto the back seat of the 28 bicycle, pushed her forward, and then went to pick up Niuniu from the kindergarten across the wall.
"Dad, in this exam, I ranked first in the class again, with a score of 100 points." Lili excitedly reported the good news to Zhou Yongfei.
"Well, not bad, Lili, I'll reward you with braised pork when I get home."
"Long live dad."
When they pushed the bicycle over, Niu Niu was already lying on the fence of the kindergarten, waiting eagerly.
"Daddy, daddy!"
Niu Niu was very happy. She shouted and ran towards Zhou Yongfei. Then Zhou Yongfei carried him to the beam with one hand. One after the other, the two daughters went home happily.
"Dad, is mom back?"
"Well, I'm back." Zhou Yongfei said: "Your mother just came back from the United States, but she will be busy building ships next, so she will probably leave early and come back late."
"Huh, mom is always like this. Dad, why don't you be busy in the factory and let mom stay with us at home?"
"Yes, and Uncle Qin, we haven't seen him for a long time."
Zhou Yongfei's face looked slightly embarrassed.
A family must make sacrifices, right? Cong Ju has always been a person who is willing to do business and has good skills. Therefore, when she was at Huating Shipyard, she was the backbone of the technology. Now that she comes here, she has to play a leading role.
As for Zhou Yongfei, when he came to the shipyard, he knew that the factory would take care of him, not many jobs were arranged for him, and the salary was very generous, so he was generally considered quite satisfied.
However, it is still a little embarrassing for a grown man to do housework and let his wife take the lead.
"Yes, I miss Uncle Qin too. Dad, the braised pork you made is not as delicious as Uncle Qin's." Lili said from behind.
Zhou Yongfei felt even sadder in his heart.
"Niuniu, Lili, have you seen the building over there? It will be built in two months. We will be able to move in this winter. Do you want to live in a new house?" Zhou Yongfei changed the subject.
"Dad, does Uncle Qin live with us? It would be nice if he lived across the door."
Why can't the topic be changed? I am your biological father!
Zhou Yongfei was riding his bicycle, feeling very unhappy. When he arrived at the door of the shipyard, he saw a familiar figure.
"Lao Zhou, Lao Zhou!"
Zhou Yongfei was immediately delighted: "Sihai? What kind of wind brought you here?"
"I was going home to visit relatives and happened to pass by here. I heard that you work here, so I came here to have a look." Li Sihai was also carrying a big net bag in his hand, which contained a lot of good things.
"Oh, let's go to my house." Zhou Yongfei greeted, then looked at the porter of the shipyard and said hello.
The family home is outside the shipyard, but Zhou Yongfei and the others are temporarily living in the dormitory, which is inside the shipyard.
As Li Sihai walked, he looked at the surrounding scene: "This Mingzhou Shipyard is really amazing. Now it can actually build natural gas ships. This is the only one in our country!"
"Uncle, my mother builds natural gas ships." Lili started to show off: "My mother is the best!"
"That is, Cong Gong used to be the top leader at Huating Shipyard. Our Zhongjiang Shipyard does not have this strength. Speaking of which, it is really unlucky. When I first said that we would assist in the construction, I went with it as soon as I got excited.
Zhongjiang Shipyard, if I had known earlier, it would have been great to have stayed at Huating Shipyard!"
Li Sihai began to beat his chest and regret his mistake.
"Lao Zhou, are you not getting good results there?"
"Yes, the missile boat business has declined, and the guided missile destroyer business has not come over either. The factory may not be able to survive!"
Zhou Yongfei frowned: "Sihai, as long as we have the skills, why are we afraid of not having a job? Mingzhou Shipyard is short of manpower. If you have an idea, I will say hello to you and the factory and let you come here to work. Here.
The salary is not low.”
"Then why are you so embarrassed?" Li Sihai felt a little embarrassed.
"It doesn't matter. When I first arrived at Huating Shipyard, we were apprentices in the same group. We have been friends for many years. We are still busy and can still help. Lili, Niuniu, you go home and do your homework first. I will take uncle there.
Find the factory leader."
In the shipyard office, Qin Baoshan looked at the people brought by Zhou Yongfei happily: "Our Mingzhou Shipyard is developing and growing, and we are in urgent need of all kinds of outstanding talents. Since Comrade Li Sihai is a skilled electrical installer, then we can keep him
Come down and work. Although there is no official establishment now, there is no difference in salary and benefits."
"Thank you, Director Qin." Li Sihai was very moved.
the next day.
"I worked at Zhongjiang Shipyard, and I am most familiar with the circuit of this kind of missile boat." Li Sihai came to the No. 1 dock and worked very hard.
"Really, you did a good job connecting the circuit of our missile launcher." Zhao Ling, the military representative, looked at the work results of the newly joined worker Li Sihai and was very satisfied.
"This circuit always had problems in the past. If it stays at sea for a long time, it will easily corrode. Therefore, we used a thermowell, which is much better than wrapping it with tape."
"Hey, there's a new worker here?" After Qin Tao came back, he made routine inspections every day. The first place he visited was the work station of the missile boat. When he saw the new face of Li Sihai, he was immediately curious.
"He's from Zhongjiang Shipyard. He has done this before and is very skilled. We don't have enough manpower to install this batch of missile boats, so we just have a capable man." Zhao Ling said.
Qin Tao nodded: "Well, good, come on, um, Representative Zhao, come over here."
Zhao Ling left with a natural expression and followed Qin Tao to the operation room nearby. No one was around. Zhao Ling thought Qin Tao was going to do something intimate. They were engaged anyway, so there was nothing to be shy about.
"Xiaoling, help me find out the origin of this Li Sihai."
"Huh?" Zhao Ling was a little surprised: "Are you worried?"
Li Sihai works quickly and skillfully. Apparently she has installed missile boat equipment before, so she feels relieved.
"I'm not worried about the people coming from Zhongjiang Shipyard." Qin Tao said: "We have to ask the Marine Corps members to pay attention to Li Sihai's actions."
The origin of the other party will not be falsified. This can be known after a quick check. Therefore, the other party should be from Zhongjiang Shipyard. However, it is precisely because of this that Qin Tao must be more vigilant.
Zhao Ling nodded: "Okay, I will arrange it."
Now that the business is over, do you want to have some intimacy now?
Qin Tao was just starting to lose his mind when the big brother made a loud noise.
"Hello? Purchasing S-300? Why am I the one doing this again?"
