While Liu Lang was "brainwashing" everyone, a meeting was being held in a conference room in the Ministry of Industry building in the capital. The host was Minister Jiang Botao. Sitting on his right was Minister Hou Changfa of the Ministry of Electric Power.
On the other side was Wang Zhendong. There were many other people attending the meeting, including managers and technical engineers from enterprises affiliated to the Ministry of Industry and the Ministry of Electric Power. Feng Liyong was also sitting among them.
As the organizer of the meeting, Jiang Botao spoke first.
"Everyone, it's a bit rushed to invite you all for a meeting on the fourth day of the Lunar New Year, so I'd like to apologize to you first! But today is the first day of work. Our country has a slogan, time is money, and we are all making money.
Yes! No?"
"Minister Jiang is right. In fact, I proposed this meeting. It is a joint meeting between the Ministry of Industry and the Ministry of Electric Power!"
Hou Changfa said.
The people below remained silent, but the two big leaders spoke. What could they say?
"What is the content of this meeting? It's very simple. Everyone must know about Fucheng Industrial Zone, and Norinco. This is Liu Lang's company. I won't explain who Liu Lang is... Just here
Ten days ago, Liu Lang and Vice Minister Wang Zhendong went to Jibei City. Norinco hopes to obtain the pipe fitting welding project of Jibei Power Plant. Our meeting today is to discuss this matter!"
Jiang Botao's words left many people confused. What is the discussion about this matter?
"Minister, there is nothing to say about Liu Lang's level. He went to the United States to study for two years. God knows what kind of high technology he learned. This project can be done if he says it can be done. I firmly support it!"
A director of the Ministry of Industry immediately expressed his support for Liu Lang. Just kidding, who in the Ministry of Industry does not know the relationship between Liu Lang and Jiang Botao? Fucheng Special Economic Zone relies on his Norinco Group, even if Norinco does not have the corresponding capabilities.
Got to support.
"We are not talking about Liu Lang's ability or not. Mr. Feng, you should introduce him!"
Hou Changfa frowned and pointed at Feng Liyong.
"Okay, let me tell you!"
Feng Liyong stood up immediately.
"Ten days ago, Mr. Liu... By the way, Mr. Liu is Liu Lang. Mr. Liu and Vice Minister Wang arrived at the Jibei Power Plant. At that time, I was in charge of the Jibei Power Plant bidding there. Mr. Liu proposed to participate in the welding project. At that time
I think this matter is unreliable. Norinco Group
After all, the group has only been established for a few months. What ability do they have to compete with foreign companies? Later, he said that he had mastered a reinforcement welding technology, which is to make the joints stronger than the raw materials through welding. Isn’t this a joke? I thought at the time that he
What a big liar!"
Feng Liyong's words first stunned many people, and then they began to shake their heads.
Reinforcement welding technology? The strength of the joint is greater than the original material. This is really a big joke.
Everyone present is considered an expert. Those department heads may not understand complex technologies, but welding is the most common and common technology, and they more or less understand it.
The most critical technology in welding technology is the combination of the welding material and the steel itself. It is not just "gluing", but the internal crystal lattice of the two materials must also fit together to form a unified stress internally.
This fusion must of course be carried out at high temperatures, and high temperatures can destroy the internal structure of the material, which will affect the strength of the material.
Nowadays, domestic welding all uses metal materials with a lower melting point than the base metal as the filler metal. The liquid filler metal is used to wet the original base metal, fill the gap, and finally achieve the connection.
The melting point of the filler material is lower than that of the base metal, so the strength is naturally lower. The strength of the combined weld will inevitably be lower than the original base metal. With domestic welding technology, it can reach 80% of the original strength of the base metal.
This is very good. In order to make up for this 20% deficiency, the welding seam generally needs to be thickened. The result is a "scar" on the base material. Not to mention ugly, the most important thing is that it affects the entire body.
The overall structure is nothing in some "silly" projects, but for projects with precise calculations of the structure, the appearance of this "scar" will affect the overall bearing strength, and this "scar" is just
Adding some hardness will greatly reduce other properties such as toughness and conductivity. It is a helpless move with huge shortcomings. Even in China, this process is not advocated.
This is a principle of welding technology, and it is also the case in Western developed countries. Of course, their technology is much better. The strength of the weld is almost the same as the base material, and other properties are much stronger than in China. This is mainly
Because their welding materials are very good, and the temperature, heat treatment of the base metal, cooling and other details are controlled very carefully, as well as the welding workers' techniques.
The welding level in foreign countries is much better than that in China, but they only use welding to make the weld more complete and closer to the base metal. I have never heard that the welding will be stronger than the base metal after welding is completed.
Feng Liyong told everyone that Liu Lang had created a new welding technology, which completely subverted everyone's imagination, and no one believed it.
Many people at the venue felt that Liu Lang was making things up. Only a few people, including Jiang Botao and Hou Changfa, had no reaction.
"Expert Feng, hurry up and get to the point!"
Wang Zhendong shouted to Feng Liyong.
"Okay, let me tell you the key points!"
Feng Liyong smiled and nodded.
"Everyone, Mr. Liu now has this technology. This technology is the most advanced technology in our country and even the world!"
Feng Liyong's words made the scene instantly quiet at first. Everyone stared in disbelief, but then the venue became excited.
"Impossible, how can you have such technology? Feng Liyong, what evidence do you have, bring it out immediately!"
"Is this Liu Lang so powerful? If it is true, then our country has a technology that has reached the international level!"
Some people questioned and others were happy, and the scene became a mess.
"Everyone be quiet, be quiet!"
Jiang Botao patted the table.
Feng Liyong continued.
"I know there are many people who don't believe it, but that's the fact. That day, Mr. Liu asked his three workers to weld the 304-type steel pipe on site. By the way, that steel pipe is right here!"
Feng Liyong pointed to a corner of the venue. A steel pipe with a length of 70 centimeters and a diameter of 30 centimeters was there. Five experts immediately walked over and leaned over to look at it carefully.
"The weld is very smooth and the appearance is almost the same as the base material. This kind of welding technology is very clever! I have never seen it before!"
One expert said, staring at the weld.
"This crack is caused by stamping and is 30 centimeters away from the weld. If it is caused by post-welding inspection, there is no doubt that the strength of the weld is greater than the base material!"
Another expert looked at the crack and said.
"Stamping can only prove strength, other indicators cannot explain it. Feng Liyong, you should have other indicator data there!"
"That's right, I got this steel pipe back and did various tests a year ago. All the data are very close to the base material, almost the same as the base material!"
Feng Liyong nodded and said.
"Oh, close to the parent material? Not more than the parent material?"
This answer is somewhat unexpected, especially those officials, who thought that the overall performance exceeded the base material.
However, the experts were so excited when they heard the answer that they all started dancing.
