v2 Chapter 162： So convinced by Mu Yang
Ten o'clock the next morning.
The three of Muyang set off for Sifang Factory and arrived in a few minutes.
However, the car could not go in directly. Mu Yang asked Li to park the car beside the gate. He wanted to get out of the car and call Feng Younan, the chief engineer of Nanche.
Feng Younan has been working in Sifang Factory for a long time, and he also proposed to invite Mu Yang this time.
After getting out of the car, Fatty glanced at the door with a width of 20 to 30 meters and praised: "The scale of this company looks very large, and it is magnificent." Mu Yang replied: "Of course, it covers an area of more than 2,000 acres and has an annual output value of more than 2,000 acres. billions of dollars. "
"Yangzi, you came all the way here from City H, and this company didn't hang a banner at the gate to welcome you, and made you wait here." Fatty complained in a low voice, feeling that Mu Yang was not taken seriously.
In Fatty's heart, Mu Yang is already a figure. Seeing that he is despised by other companies, he can't help but feel injustice for Mu Yang.
"Fatty, don't worry about this, Xinghai Company is not well-known in the machinery industry, and I'm not a big man. I was invited by the chief engineer of the group, Feng Younan, which is a personal invitation.
Even if he is the chief engineer of the group, he is not a local snake. The interpersonal relationship within a state-owned enterprise is complicated, not as simple as you think
Such large state-owned enterprises rarely hang banners if they are not inspected by higher-level leaders. "Mu Yang doesn't feel ashamed. After all, he has lived two lifetimes. Although he can't be flattered and humiliated, after accumulating his life experience, he will definitely be more indifferent to social affairs than Fatty, a fledgling college student.
In any case, he is currently a small person in a private enterprise.
He has a system and is a bull, but this is his secret, and he can't show it in front of others: I have a system, so I won't kill you.
"Okay, I don't know much about this." Fatty stopped speaking. When he came to other people's territory, he would not make trouble. He was like a little follower who would do whatever Mu Yang asked him to do.
Mu Yang called Feng Younan and said that he had arrived at Sifang Factory.
After hanging up the phone, I waited for more than ten minutes before I saw Feng Younan. After all, he was fifty or sixty years old, and he was out of breath if he walked in a hurry.
Feng Younan was also shocked when he saw the Rolls-Royce beside Mu Yang. He didn't expect that Mu Yang's car was of a high quality, higher than the general manager of the group.
Mu Yang read the surprised look in his eyes, and was a little embarrassed. Driving a Rolls-Royce to someone else's site was indeed a bit high-profile, but it was also the best way to show his strength.
Feng Younan laughed, walked over and shook hands with Mu Yang: "Mr. Mu, it's been a lot of hard work along the way. I thought you were coming by plane, so I'm going to send someone to pick you up. Unexpectedly, you guys drove all the way here."
He didn't know much about Xinghai Machinery Company, he just read the company's profile at the Industry Fair.
He suddenly felt that both himself and the leaders of Sifang Factory underestimated Xinghai Machinery Company.
"Mr. Mu, I hope you don't mind the poor reception." Feng Younan greeted politely.
Mu Yang smiled lightly: "Mr. Feng, you're welcome, I'm here for technical exchange, our company sells equipment to your company, and our after-sales service must be in place. I'm still worried that I won't be able to help you solve the problem. scold."
Feng Younan waved his hand and said, "Where, where, your handheld laser welding equipment is very useful, which has solved our welding deformation problem.
However, our production workshop and process engineers are not clear about the standard of laser welding seam, such as the welding width, the excess height, the penetration depth is qualified, and the equipment parameters are more suitable. "
Muyang said: "Well, this is easy to handle. In fact, our product manual also describes the recommended process parameters and welding seam standards."
Feng Younan sighed: "They have read it, but some details are not clear, and there are still many problems in the specific operation details that need to be connected with your company, so I can only trouble your company to send technicians to come over, I didn't expect you to come in person. ."
Mu Yang apologised a little: "I'd better come here in person. After all, it's a product I designed. It is estimated that the problems you encountered cannot be solved by ordinary technicians. I'm also very sorry for causing you trouble."
Feng Younan waved his hand and said it was fine. The problem was not the quality of the equipment. He was still very satisfied with the equipment of Xinghai Machinery Company.
"Well, it's fine if you come here, let's advance to the company." Feng Younan instructed the security guard to lead Li Yi to the parking lot to park, while he walked side by side with Mu Yang.
While walking, Mu Yang looked around the Sifang Factory and asked casually, "Mr. Feng, what is the output value of the Sifang Factory this year?"
"This year, it's estimated to be around 6 billion yuan."
"I heard that all high-speed trains are made of aluminum alloys, subways are made of stainless steel, and 160-kilometer trains are made of carbon steel. This statement is correct."
"Well, yes, you know it quite well. Oh, I almost forgot that you are also familiar with the welding process of the car body.
Feng Younan and Mu Yang chatted as they walked and walked to the subway car production workshop.
The fat man followed behind with Muyang's computer bag on his back. The driver, Li Yi, didn't follow. He sat in the car and waited for the boss.
Sifang Factory is a big place, and there is also a distance from the company gate to the subway car production workshop.
With Feng Younan with him, there was no obstruction along the way.
Walking through the office area and coming to the production area, Muyang saw the spacious workshop.
The bright floor paint, within the defined yellow line, the carriages are elevated one by one. At a glance, Muyang can see several rows and columns of carriages. This is a carriage that has been completely manufactured, and electrical appliances are being installed. .
After walking some distance, Muyang saw the aluminum alloy body manufacturing workshop.
The manufacturing process of aluminum alloy car body starts from the bottom frame. The bottom frame is first welded on the front, polished on the front and back, paved with the floor and airtight test, welded on the end wall, automatically welded on the front, back and side walls of the roof, and processed as a whole. Cab assembly welding:
Finally, it is a large combination of welding of the above-mentioned major components, straightening and leveling, and after the rain test is completed, the painting is started.
Fatty followed behind, looking around, very curious, and made a sudden realization, "Oh, it was produced like this." Passing through the high-speed rail production workshop, Feng Younan brought Mu Yang and Fatty to the stainless steel car body production workshop.
After entering the workshop, some workers were also a little curious when they saw Feng Younan bringing two young people into the workshop:
"Who is the young man next to Mr. Feng, and he is used to accompany him, the client? It's a bit different."
"Who knows, to see if they are talking and laughing, maybe it's his son."
"My son is a hairy, I heard that President Feng has only one eldest daughter, who is already married.
Listening to the discussions of these workers, it seems that Feng Younan is quite popular among the workers, which is related to his frequent roots in front-line production.
Feng Younan came to the production area of the No. 6 carriage. After seeing the welding supervisor, he asked him to gather the welders who were responsible for greeting the laser welding operation, saying that the experts from the handheld laser welding manufacturer had come.
The welding supervisor looked around, wondering: where? Or the young man next to you? Not like that.
They have a lot of experience in this line of work. Generally, they can be called experts. They are a little old, at least not a hairy boy in his early twenties!
The welding supervisor was suspicious of Mu Yang and Fatty beside Feng Younan.
Although there were doubts in his heart, the welding supervisor would not ask Mr. Feng in person, so that Mu Yang and Fatty could not step down. After all, Mr. Feng brought them here.
The welding supervisor has a good relationship with Mr. Feng, and Mr. Feng often helps them solve technical problems in the workshop. Some time ago, Mr. Feng mentioned this to him and asked the manufacturers of handheld laser welding to come over for technical exchanges.
In fact, when Xinghai Machinery Company transports the handheld laser welding equipment to the workshop of Sifang Factory, the technicians will follow the trucks and train the welders of Sifang Factory in theory and practical operation. The time is relatively short, but basically all The package teaching package will wait until they can get started before leaving.
But after a month of use, the welder found that many details of hand-held laser welding could not be understood, so he proposed to let Xinghai Machinery send people to the scene to explain the training, preferably an expert in this field.
More than ten minutes later, dozens of welders gathered in the No. 6 subway car production area.
The workshop was a little noisy, Feng Younan stood at a higher place, pointed at Mu Yang, and said a little loudly:
"Let me solemnly introduce to you, the person next to me is the general manager of Xinghai Machinery Co., Ltd., the inventor of the handheld laser welding equipment, Mr. Muyang Mu.
Mr. Mu is very young, but he is very proficient in welding technology. If you have any questions about laser welding technology, you can ask Mr. Mu for advice. I hope you will cherish this hard-won opportunity. Mr. Mu has come all the way from H city. not easy. "
After the introduction, everyone took a serious look at the young man in front of them.
They even invited the boss to come over instead of sending technical engineers. Some welders didn't quite believe what Mr. Feng said. They felt like they were just polite words from the people on the scene.
Muyang, a tall man, said directly and politely: "Mr. Feng is very polite, Sifang Factory is a great enterprise and has created countless national firsts in China, such as the first domestic high-speed EMU with a speed of 300 kilometers per hour in China... So, I It is a great honor to come to Sifang Factory to communicate with you.
Mu Yang first touted the Sifang Factory. When he said that these were the first in China, the workers immediately showed proud expressions on their faces.
Noticing the expressions of these workers, Mu Yang felt that the time was almost right, and continued, "Although hand-held laser welding is my own invention, it cannot be said that I am very proficient in laser welding operations.
Maybe the masters have been very handy in the application of laser welding equipment, and have summed up their own set of experience. I also hope that I can learn some dry goods from the masters. "
Mu Yang is very humble, but he doesn't belittle himself. He calls this problem-solving "equal communication". These old masters also want to save face. He said that these masters instantly increased their favorability to Mu Yang and gained "status". Equality, everyone can open their hearts to communicate
After Mu Yang finished speaking, he kept a faint smile on his face.
A master raised his hand and asked politely: "Mr. Mu, hello, I would like to ask what color is more suitable for this laser welding seam. Some colleagues say that silver is the best, but I don't think so, golden yellow. most.
Mu Yang turned his head and glanced at the old master who asked the question, without thinking about it, he answered directly: "This master asked a good question, and the key point of laser welding came up.
We are welding stainless steel. We used argon arc welding in the past. When the welding current is low and the welding speed is fast, the color of the weld is silvery white. As the welding current increases or the welding speed becomes slower, the color of the weld becomes golden yellow. Blue, then to dark blue, to gray.
The same is true for laser welding stainless steel. If it is silver-white, it looks good, but there may be poor fusion and shallow penetration. It is best to be golden yellow, and blue can also be used, but do not turn gray. Seam toughness deteriorates.
It's okay if the weld is a little gray, anyway, the weld will eventually be washed white. ’
"Thank you, Mr. Mu, I finally understand it."
After Mu Yang just finished answering this question, everyone felt that he answered very well.
Then, another worker master rushed to ask: "Mr. Mu, when the welding arc is received, the welding torch always sticks to the wire. How to solve this?"
Mu Yang replied quickly: "The question this master asks is indeed very common and troublesome.
Sticky wire, indicating that the welding wire is not blown.
Master, you can increase the welding power a bit, and then adjust the scanning width to about 2.7mm. Also, you can check whether the laser focus has hit the welding wire.
In addition, it is also related to the posture during welding. The arc end of laser welding is not as particular as other arc welding. After welding, it can be directly pulled away in the direction of the welding wire, and it is not necessary to stay on the welding seam.
If the wire sticks, click again to melt the wire. Occasionally sticky silk, this is difficult to avoid. ’
When Mu Yang was explaining, many workers suddenly understood, and shouted, "Oh, so that's what happened, no wonder"
Seeing that the workers listened to it, I felt like I didn’t invite Muyang over in vain. Although the laser welding equipment has been used for a month, the welding engineers still can’t understand the principle. This equipment is easy to master, but some key points are not Good to understand.
Next, many workers asked questions, and Mu Yang answered the adjustment of process parameters such as scan speed, scan width, peak power, duty cycle, pulse frequency, etc., and how each process parameter affects welding. I even did the welding myself. These workers were completely convinced by Mu Yang. They not only understood the technology, but also had a very skilled level of practical operation.
Perhaps the operation of hand-held laser welding is nothing, and it can be used skillfully without learning a few days.
What shocked everyone was that next, Muyang also showed them a large swing welding of argon arc welding, and it was a 45-degree fixed pipe **** welding with obstacles!
This position includes horizontal, horizontal, vertical, and overhead welding, and there is interference during welding. The difficulty of welding is the most difficult among the test items.
To put it this way, if we say that the learning difficulty of laser welding is 10 points, argon arc welding is 60 points, horizontal welding is 90 points, vertical welding is 100 points, and overhead welding is 150 points. The difficulty of 45-degree fixed pipe **** welding with obstacle interference plus obstacle welding is 200 points.
Qualification is 200 points, and Muyang Welding is very beautiful, you can score 500 points!
Therefore, the welders around were admired, and even Feng Younan was shocked.
"Niu Cha, the best welders in our factory are not as good as Mr. Mu!"
"Yeah, hand-held laser welding is a fool, but this argon arc welding is purely based on personal skills, and it won't work if you don't practice for a few years. Mr. Mu, you are so young, how can you master this skill? This fish scale welding looks like a machine. Welding makes no difference.
"I haven't been able to learn this big swing technique very well, and I can't swing it! And it's still such a high position difficulty!"
"I think the big swing is easy to learn. The problem is that vertical welding and overhead welding are difficult to weld, and obstacles are added. The problem is that the welding effect is very good, and there is no rework, so I have to admire it." One of the experienced welding technicians The welder was surprised.
Mu Yang saw that the workers admired him so much, how could he be embarrassed to say that he had hung up, his welding operation skills were already at the fifth-level intermediate level.
He had no choice but to laugh: "Practice makes perfect, so can you."
"No matter how skilled people are, they can't learn it. It seems that learning this big swing welding depends on your talent. Mr. Mu is amazing!" The workers gave him thumbs up. After hand-held laser welding, the workload of argon arc welding is greatly reduced.
Only through the communication did everyone know that Muyang is in his second year of sophomore year, but he is already the boss of two companies, and his assets are high, worth tens of billions of yuan, and the company's annual output value is also billions of yuan.
Of course, this was said by Fatty. He was a little unhappy that Sifang Factory didn't pay attention to Mu Yang when he entered the door.
Feng Younan didn't know much about Muyang's situation, and the other welders didn't know much.
The crowd was shocked again.
At such a young age, he is still worth tens of billions of yuan. In terms of assets, he is no worse than Sifang Factory.
The most admirable thing for these workers is that Muyang's welding skills are better than any of them. Some people can't compare to him after practicing for more than ten years.
The three of Muyang set off for Sifang Factory and arrived in a few minutes.
However, the car could not go in directly. Mu Yang asked Li to park the car beside the gate. He wanted to get out of the car and call Feng Younan, the chief engineer of Nanche.

Of course, this was said by Fatty. He was a little unhappy that Sifang Factory didn't pay attention to Mu Yang when he entered the door.
Feng Younan didn't know much about Muyang's situation, and the other welders didn't know much.
The crowd was shocked again.
At such a young age, he is still worth tens of billions of yuan. In terms of assets, he is no worse than Sifang Factory.
The most admirable thing for these workers is that Muyang's welding skills are better than any of them. Some people can't compare to him after practicing for more than ten years.
