Great warships

Chapter 201 Commencement of Building an Aircraft Carrier

Qin Tao was originally engaged in shipbuilding, but ended up getting involved in the aviation industry, so he was not doing his job properly.However, after chatting with Mr. Song, he was still very proud. In the future, the 611 Institute will do some business, which can be regarded as subsidizing the research and development of military aircraft, and he has done a good deed.

In the future, if Mr. Song and the others come up with the J-[-], free their hands, and bring out the vertical take-off and landing fighter jets along the way, it will be even more against the sky.

But these are things for the future. Now, of course, I still have to do my own thing.

Mingzhou Shipyard.

Crackling firecrackers sounded, and Qin Baoshan stood on the newly built slipway and said loudly: "Today is the completion ceremony of our [-]-ton slipway, and our President Qin has returned. Now, he is welcome to speak to us. "

As soon as Qin Tao came back, he caught up with the ribbon-cutting, and he was extremely excited. He looked at the brand new [-]-ton cranes on both sides of the berth, the shiny track below and the scaffolding that had been erected, and tried his best to calm down. Mood, said: "For our Mingzhou Shipbuilding Industry Group, this is a new beginning! Now, the slipway has just been completed, and we will build a [-]-ton aircraft carrier. Next, there will be ten ships on this slipway. Cargo ships and oil tankers of the [-]-ton class, warships of tens of thousands of tons, and even aircraft carriers of tens of thousands of tons! Our big ship of Mingzhou Shipbuilding Industry Group will also set sail and ride the wind and waves!"

"Now, I also announce that the first steel plate has been officially cut for the Chakri-Nalubet aircraft carrier!"

In his voice, the plasma cutting machine imported from abroad began to spit out flames. Compared with oxyacetylene flames, the cut surface is more neat, and it can even be welded without grinding. It is a good tool for speeding up shipbuilding.

Although the contract had been signed, the start of construction still waited until Qin Tao came back. This was also because the new berth had to be opened.

After the first steel plate was cut, everyone applauded again. Under the eyes of countless people, the crane lifted the steel plate to the hydraulic bed, and began to shape it. After being pressed into a qualified shape, it can be welded on the ship's berth.

After Qin Tao announced the steel plate cutting, he looked at Steven, the shipowner's representative who was in charge of supervising the work.

"Mr. Steven, do you want to say something?"

Although this [-]-ton aircraft carrier was built for Siam, the Siamese also knew that their own technical level was unreliable, so they hired Westerners to supervise the work.

Steven is from Vickers Shipyard in the UK. Although they didn't get the order, they sent a representative to supervise the manufacturing, which is considered a recognition.

Steven nodded, walked towards the microphone, and looked at the people below: "In the future, I will supervise the construction of this aircraft carrier. Although there are many places on the design drawings that use civilian standards, I will follow the standards of warships." If there are any mistakes, you will be reworked! You can scold me behind my back, but as long as it does not meet my requirements, I will not sign for you!"

Hmph, who are you scaring?

Hearing his words, the boatmen below were somewhat disapproving. If they had never had contact with foreigners before, they might not be used to it. But now, the natural gas ship has always been manufactured under the supervision of foreigners. Cong Gong and those foreigners chatted and laughed happily, and dealt with it properly. The foreigners have to give Cong Gong a thumbs up!

"For example, now, you have enough manpower. In addition to welding the hull, you can also weld the saddle tube test pieces inside the hull first. I request X-ray inspection for these test pieces."

With the continuous development and growth of the shipyard, all kinds of equipment are also available, and there are also X-ray machines for inspecting welding quality. Everyone is used to X-ray inspection of test pieces, but this kind of saddle pipe has never been used. Pass!

After all, if you are not proficient in the craft, not to mention the X-ray machine, it is easy to find problems even visually.

Looking around the world, no representative of the shipowner requested that this kind of workpiece be inspected with an X-ray machine. This Steven is purely trying to make things difficult for others!

What are Saddle Tubes?
In fact, it is a circular pipe, which is connected with other pipes to form a tee. If it is thinner, such as a water pipe, it can be connected directly to the tee connector. However, if the pipe is thicker, then you have to Welded.

When welding, the inserted circular tube and the inserted circular tube need to cut off a part of the contact part to match. The cut of this part is the same as the saddle, so it is called the saddle tube.

This kind of cutting and welding is a test of the welder's skills.

Steven is the new official's third fire, and he wants to show off his prestige.

"In that case, I'll weld a test piece and show it to Mr. Steven." Just then, a petite figure came out.

"Cong Gong!"

The current Cong Ju is taking the lead on the natural gas ship. She did not participate in this lively ceremony, otherwise she would have to stand on it. After all, she is a senior executive of the shipyard. However, she is not interested in these, just passing by.

What's more, Cong Ju's body was also wearing ordinary welder's clothing, coupled with her thin figure, she was not inconspicuous at all.

Qin Tao knew that Cong Ju was here to kill the vigor of the representative of the foreign ship owner, so as not to make the other party look like no one.

"Cong Gong, give way, let me do it." At this moment, another voice sounded: "If you come on stage, it means that there is no one else in our shipyard! I will come first, if I fail, you will come again Come on."

Welder Zhang Yang also stood up!
Cong Ju has been in Mingzhou for a long time. Under her precepts and deeds, she has brought together a large group of backbone welders. Zhang Yang, like Zhao Changshui, is also an old welder in Mingzhou Shipyard.

Hearing Zhang Yang's words, Cong Ju smiled, and just about to nod, Steven said there: "No, I want her to weld, if her test piece is okay, then this project will be exempted from inspection in the future, if She is not good at soldering, all the soldering pieces have to go through the X-ray machine!"

After going through the X-ray machine, it is not a matter of saying a word, and it is not just a waste of some electricity. It requires film. All the saddle tubes of this aircraft carrier have to be photographed, and the film alone will cost tens of thousands of yuan!

Now, Steven has fallen for Cong Ju. In his eyes, the thin Cong Ju must not be very skilled. Like a brush.

"Mr. Steven, are you sure?" Qin Tao looked at Steven with great interest. This guy was going to come up to show his prestige first, but now he was directly abused by Cong Ju. That scene must be beautiful.

Steven nodded: "Yes, it's her!"

"Sister Cong Ju, please show me your skills, and let Mr. Steven have a look. Our Mingzhou Shipyard is Crouching Tiger, Hidden Dragon."

So, on the welder's console beside the slipway, countless people formed a circle.

Although it is a test piece, it can't be wasted. What is welded is a normal workpiece. Cong Ju said to the people on the side: "Excuse me, prepare the materials, a two-meter-long six-inch tube, and a one-meter-long four-inch tube." Tube."

Six inches and four inches are both imperial units. If converted to a standard, they correspond to DN150 and DN100 respectively, and the inner diameters are 150 mm and 100 mm respectively. The diameters of these two pipes are different!
This kind of welding is not easy. At this time, looking at the two pipes with different diameters, the expression on Steven's face became wonderful.

How is this going?

Could it be that this seemingly unremarkable welder is really capable?

Steven was a little curious.

"Give me the angle grinder." Cong Ju continued.

When Cong Ju's slender right hand picked up the angle grinder, Steven couldn't help but said: "Don't you need to stake out first?"

To weld the two pipes together, an opening is required, which is similar to the ancient mortise and tenon structure, and the opening is a complicated curve.If described by mathematical knowledge, it is called a hyperbolic parabola, the equation x^2/a^2-y^2/b^2=2z(a, b>0).

An experienced master will wrap the tube with a piece of paper, determine the size of the paper, then fold the paper in half, and then draw lines on the paper. After various operations, cut it out with scissors, re-embrace the tube, and draw with a pen Draw that curve, so that the shape of the opening can be determined, and the two butt joints can only be cut after the two joints are drawn. (Using this piece of paper, the dimension reduction operation was successfully realized, changing the three-dimensional shape of the nozzle to the two-dimensional plane of the paper.)
Later, with a computer, you can stake out directly on the computer, that is, calculate the equation, then print out the paper and mark it directly.

In the West, the complex curves of various joints are almost all computer lofted and then processed, and some machines can even cut them automatically.

What now?
This short female worker actually wants to start directly?Or use an angle grinder?It is estimated that it is a straight cut!
Thinking of this, Steven has a feeling of watching the show again. Watching the female worker cut it, there will be problems, and it is impossible to look directly at it after welding.

hum!The angle grinder sounded, Cong Ju held the vibrating machine in her hand, and approached the side of the six-inch tube, and then, sparks flew.

There was a loud noise, and the flake-shaped grinding wheel was already in close contact with the six-inch tube. Then, Cong Ju's hand moved habitually, and the sparks also began to change direction.

Still not a straight cut?
Steven was a little curious.

Cong Ju moved very quickly, and the angle grinder quickly made a circle around the side of the six-inch tube. Finally, when Cong Ju closed the angle grinder, there was a bang, and the cut part fell down, revealing a mouth.

When he saw the opening, Steven suddenly laughed: "The two sides are asymmetrical! What are you going to do? Is this a waste product?"

If you want to poke the four-inch tube into the side of the six-inch tube, you have to make an opening on the six-inch tube, and the opening must be at least symmetrical on both sides, right?

"Sixth saddle pipe." Cong Ju replied, and then continued to cut one end of the four-inch pipe.

Number six saddle pipe?what is this?
Although Steven is the representative of the shipowner, this is also his first day here to work. He has not come into contact with the design drawings yet, and he does not know what the No. [-] saddle pipe is.

It's just that other people are looking at Cong Ju with admiration.

"Cong Gong is too powerful."

"I thought I could become a teacher, but I didn't expect that I only learned the fur of Conggong!"

"Cong Gong, you are the person I admire the most!"

Everyone is applauding, which means that this workpiece is not a waste product. Therefore, this asymmetrical opening should be done on purpose. What kind of workpiece is this?
Suddenly, Steven came to his senses: "Does this have to have a certain inclination?"

Oh God, can you not be so awesome?

Welding two pipes of the same caliber into the shape of a tee is already the ceiling of ordinary people. Only a very small number of excellent welders can do the welding of two different calibers. , the thin-looking welder in front of him not only needs to weld tee pipe joints of different calibers, but also has a certain inclination angle!

(If you describe it, it is the same as a tree branch growing on the trunk. Our cluster workers just want to weld the branch to the trunk, which is the difficulty.)
Because of the inclination, the openings on both sides of the interface must be asymmetrical, and symmetry is a right angle.

"That's right, No. [-] saddle pipe, with an inclination of [-] degrees, is the most technically difficult of all saddle pipes." When the sound of the angle grinder stopped, Cong Ju replied: "Now, Mr. Steven Check it out."

As Cong Ju said, she moved the one-meter-long four-inch pipe. The polished opening poked at the opening of the six-inch pipe. On the ground, the two were perfectly combined. Not even a gap!

Perfect, so perfect!
In Europe, only a CNC cutting machine can cut out such a perfect interface. Now, the other party didn’t even draw the wire, just holding an angle grinder, and fiddled with it!

Needless to say the next welding, Steven was completely shocked by the cutting skills alone. When the butt joint was done, he saw that the seams were perfectly fitted, and Steven raised his thumb: "OK, OK, you are the best, I admire you! This saddle tube is worth it.”

"That can't be done." Cong Ju said: "Now it's just preparing materials, and the welding has not officially started yet. Now, we have to start welding!"

As she spoke, Cong Ju picked up the welding handle with her right hand, and poked the welding rod on the seam, sparks burst out, and Cong Ju turned her head aside.

Nima, can you stop hitting people like this?This is blind welding!
Cong Ju only picked up the welding handle without a mask, so she couldn't see the weld seam with her eyes. The arc contains strong ultraviolet rays, which are harmful to eyes.

Experienced old welders can weld a beautiful straight fish scale pattern with their eyes closed, but now they are welding curves!

Cong Ju can accurately follow the weld seam without looking at it?How unnatural this must be!

Steven was completely shocked.

God, there is no such thing as a welder in the West, but this thin female worker in front of me can actually do it?

Steven's eyes kept staring at the welding sparks, not even afraid of hurting his eyes.

"Come on, everyone, help to look through."

Following Cong Ju's greeting, everyone came over and helped to turn the tree branch-like device half a circle, exposing the unwelded part underneath.

The electric welding in Cong Ju's hand sparked again.

"Square ruler." Cong Ju shouted.

The extra-large square was placed on the pipe, and the two lines at a [-]-degree angle coincided with the centers of the two pipes.

The sighs of the crowd resounded again.

"If I weld, I have to adjust it repeatedly and fix it with fixtures. Master Cong Gong's eyes are more accurate than a ruler!"

"That's right, Mr. Cong's job is absolutely dead!"

Cong Ju smiled, raised her right hand, wrote 123 on the tube with chalk, and stood up.

"As long as Mr. Cong welds it, there will be no waste products. I really want this 123 mark to be my own." Zhang Yang said.

In Huating Shipyard, Cong Ju's serial number is 123. Every product she has welded will write 123 on it, which is convenient for accountability, and 123 has become a glorious mark.

Representatives of demanding foreign shipowners will sign when they see this mark, without any inspection at all.

After coming here, Cong Ju still kept this tradition.

"Ma'am, your technique is perfect!" Steven said, "In the future, these saddle tubes will not need to be inspected by X-ray machines."

"That's not okay, Mr. Steven, my soldering piece hasn't been inspected by a strict X-ray machine yet, how can this work?"

"No, no, no need." Steven shook his head again and again: "You have the best welders in the world here, I am very assured that your skills are better than any welders I have ever seen."

"What about other people's technology?"

"With a welder like you leading the team, I believe they will all follow your example, and they don't need to go through the X-ray inspection anymore."

Cong Ju showed his hand, and Steven was completely convinced. At this moment, his eyes were full of admiration.

"It would be even better if you come to lead the team to weld this ship." Steven continued.

Cong Ju shook her head: "I'm sorry, the schedule for our boat is also very tight, and I will come when I finish working on that boat."

Following the direction of Cong Ju's finger, Steven saw the natural gas ship in the dock over there, and his eyes were full of admiration: "It turned out to be the welder who welded the MOSS tank, no wonder the technology is so good!"

"She's not a welder, she's the engineer in charge of that ship." Qin Tao said.

What, the engineer in charge?Steven looked at Cong Ju with adoring eyes: "You are an engineer, and you actually weld yourself. I admire your spirit!"

"Thank you." Cong Ju looked at Qin Tao: "Boss Qin, our MOSS tank will be hoisted soon. Would you like to guide me?"

"I can't talk about guidance. I'll go and have a look." After Qin Tao finished speaking, he looked at Steven: "Mr. Steven, the current general manager of this ship is the director of our shipyard, please believe , we will definitely strive for perfection, excuse me."

Qin Tao strode out with Cong Ju, and when he left the slipway here, Qin Tao said with a smile: "Sister Cong Ju, you are in Huating Shipyard, have you welded this thing?"

Cong Ju smiled: "Sure enough, I can't hide anything from you. In the Huating Shipyard, I used three months to weld more than 2000 saddle pipes. From the initial pass rate of [-]% to the final pass rate [-] percent."

Experienced masters are all trained. If Cong Ju hadn't welded thousands of pieces, how could he be so familiar with them? Even the lines of the saddle pipe interface are clearly remembered, and they are all transferred to his hands. Kung Fu.

If you change to another workpiece, it is not necessarily the case.

Although Cong Ju is young and thin, she has climbed to the top of the welder industry.

When we arrived at the dock, the hoisting work had already started.

The shiny aluminum alloy tank was hoisted by a crane, and the operator of the crane was also the most skilled worker in the shipyard. At this time, the huge aluminum alloy tank was steadily moving towards the opening at the front of the liquefied gas ship. The diameter of the opening is only forty centimeters larger than the opening of the aluminum alloy tank. If there is a slight deviation, there may be a scratch. Once a scratch occurs, the aluminum alloy tank will be useless!

The crane driver's operation was extremely smooth. The huge jar entered the first opening steadily, and then fell down smoothly.

"Tighten the installation!" Cong Ju shouted loudly.

The aluminum alloy tank cannot be directly welded to the steel hull, so, at the contact part, a special transition joint made of aluminum alloy, titanium, nickel and stainless steel is used through explosive welding. This joint, Cong Ju After a whole month of tinkering, it finally matured.

When the setting sun went down, the first aluminum alloy tank body was finally installed, and the aluminum alloy shell was no longer visible. A layer of special heat insulation material began to be wrapped around the outside of the spherical tank.

"It will take another two weeks to install the entire tank, together with the laying of the pipeline." Cong Ju said to Qin Tao: "The next step is the installation and commissioning of the equipment on the bridge. It can be delivered, earlier than our scheduled delivery time."

Qin Tao nodded: "Although this ship was built later, and the technology is very difficult, everyone worked overtime during the whole construction process and endured hardships. I am very happy. Our shipyard has a group of workers who are not afraid of hardships. .”

"The shipyard didn't treat us badly." A nearby boatman said to Qin Tao while arranging insulation materials: "We have overtime pay for overtime work, so we can make more money. Those who have gone to college, and those who go to big cities to work People in business, people in business, do not make as much money as us, so how can we not work harder?"

Those who make atomic bombs are not as good as those who sell tea eggs, and the income of the workers in the shipyard exceeds that of those who sell tea eggs. So, what are they not satisfied with?
The workers of this era are so sincere.

Qin Tao smiled: "As long as you work with me, Qin Tao, you will have meat to eat. We are playing with technology, not relying on labor cost advantages. If you work hard, your life will get better and better in the future."

Although everyone doesn't understand the advantages of labor costs, they all know that being a worker under Qin Tao is the happiest worker in the country!
