Chapter 175 MOSS tank quality issues (additional update)

"There are no problems with the overall design. Then it depends on the construction. As long as the quality is ensured during the 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. The most capable overseer will be sent over, and it is not certain whether it will be Carrasco.

 The ship was handed over to Cong Ju, and Cong Ju shouldered this responsibility without hesitation. The design has been completed, and the next main task is welding. When it comes to this, she is very good at it.

"Gong Cong will be busy again in the future, but the factory will take good care of employees' personal families. Gong Zhou will not have too important tasks. He can go to and from get off work on time and will have enough time to pick up and drop off his children." Qin Thao said.

 Cong Ju nodded: "Thank you very much."

“What a pity, this kind of ship waste is too serious.” Yang Dawei was already sighing from the side.

Although the design is good, look at the bottom of the five big balls. How much space is wasted? 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 not happen until our shipyard develops to a certain extent."

 Now, it’s just the beginning. They are the first in the country to eat crabs, and they will also become leaders in this industry in the future!

Moreover, in the future, 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 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 cans. If the delivery time is delayed due to unqualified welding of these aluminum alloy cans, they will need to compensate. What's more serious is that the company's reputation has been damaged and it will no longer be able to accept natural gas ship contracts in the future.

 As the person in charge of this project, Cong Ju is very anxious.

Even though she was thin, she ran quite fast. She was the first to return to the welding workshop. She looked at the air holes in the welds and her face was extremely ugly.

“Cong Gong, is there something wrong with the machine made by the islanders?” An old master said: “The islanders have bad intentions, maybe there is something weird in the machine.”

“That’s right, if it doesn’t work, we will use manual welding. This automatic equipment is just unreliable.”

Amid everyone's discussion, Cong Ju looked at the welding seam carefully. There were many pores on the welding seam 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. Only after Qin Tao analyzed it like this did she realize that it was true during the previous training. I've heard of it, but I didn't meet it 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 convert the entire welding workshop into a constant temperature and humidity system.”

"What?"

 Everyone was stunned again.

In this day and age, it is good 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?

 Also, how much electricity does that thing cost?

 As a result, how much will their production costs increase?

 “Qin Gong, does this have to be the case?” 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, and 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 even if conditions were met and creating conditions without conditions 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.

 “Dad, 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 next to 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, that’s good, Lili. I’ll reward you with braised pork when I get home.”

 “Long live daddy.”

By the time she pushed her bicycle over, Niuniu 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 another, 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, there is also Uncle Qin, we haven’t seen him for a long time.”

Zhou Yongfei's face was slightly embarrassed.

 As a family, there must be a sacrifice, 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 technical backbone. Now that she comes here, she has to take the lead.

Zhou Yongfei, when he came to the shipyard, knew that the factory would take care of him, not many jobs would be arranged for him, and the salary would be very generous, so he could be considered relatively satisfied.

 However, it is still a little embarrassing for a grown man to do housework and let the women of his family 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 this topic be changed? I am your biological father!

Zhou Yongfei was riding his bicycle, feeling very unhappy. When he came to 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 worked here, so I came here to take a look.” Li Sihai also held a large 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 temporarily live in the dormitory, which is inside the shipyard.

As he walked, Li Sihai 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's right, Cong Gong used to be the top leader at Huating Shipyard. Our Zhongjiang Shipyard doesn't have this strength. Speaking of which, it's really unlucky. When I first said that we wanted to 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 business of missile boats has declined, and the business of guided missile destroyers has not come over. I am afraid that the factory will not 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 work here. 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 in love for many years, so we can still help with this little work. Lili, Niuniu, you go home and do your homework first, and 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 is 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 formal 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 get corroded easily. Therefore, we used a thermowell, which is much better than wrapping it with tape.”

“Hey, a new worker is here?” After Qin Tao came back, he made routine inspections every day. The first place he visited was the missile boat work station. When he saw the new face of Li Sihai, he was immediately curious.

"He is 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 person." Zhao Ling said.

Qin Tao nodded: "Well, good, come on, um, Representative Zhao, come 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 already engaged anyway, so there was nothing to be shy about.

 “Xiao Ling, help me check 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 other party's origin will not be falsified. This can be known after one 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 make arrangements."

 Now that the business is done, do you want to have some intimacy now?

 Qin Tao was starting to lose his mind when his eldest brother made a loud noise.

“Hello? Purchasing S-300? Why am I doing this again?”
