"Mr. Du, how much does this instrument cost?"

A young worker couldn't help but ask.

"Is this the price that Mr. Liu bought back from the United States? It's about 300,000 US dollars, which is more than 2 million yuan!"

"What? more than two million! Oh my god!"

Everyone was so frightened that they shrank their necks, and there were more than two million machines in one machine, which was terrible.

They don't know that this is the price in the US market, and if it is imported into China, the price will at least increase by two or three times, and it will not be able to come down without 10 million yuan.

"Don't pay attention to the price, I'm going to show you what this iron pipe looks like, Xiao Sun, take the pipe out!"

Soon this iron pipe was placed in front of everyone's eyes, yes, a position of the iron pipe was torn open a twenty centimeter long opening, neat, under nearly 100 atmospheres of pressure the iron pipe became extremely fragile, but the people present did not squeak, one by one eyes stared at the boss, they saw an incredible scene.

It's normal to tear up, but it's not the right place to tear it! Isn't it the right position where it should be welded? Why is it 20 centimeters away from the weld? This is not logical!

How is this possible? Even the best welders can only increase the strength of the weld to 90% of the overall strength through superb technology, which is a recognized criterion of the welding process, but now, this criterion has been broken!

"Everyone, see it, this is the process method, what did I just say? welding technology is not just splicing, with the more and more developed technology, the improvement of technology has also developed, many technologies are beyond our imagination, who of you can imagine that the development of welding technology can make people feel a little stone into gold?"

Duxin said with a smile.

"Mr. Du, is this technique the best in our country?"

"Well, it should be regarded as this, in fact, this technology has not yet been popularized in China, and it has just entered our country for a few months, and it was brought in by Mr. Liu from the United States!"

"Mr. Liu!"

Everyone heard the name of this legend again.

"This welding technology originated in the island country, they were created by a welding factory five years ago, and later the Americans also learned it, and it just so happened that Mr. Liu learned this technology in college.

However, even in the United States, this technology is still in the experimental stage, not fully understood, but Liu Lang is not an ordinary person, he learned and improved, completely understood this technology, and recorded all the steps in detail, I just learned a little skin, can only weld ordinary iron castings, as for more advanced parts, such as high-pressure pipe fittings, Stainless steel materials can't be finished yet, of course, it's only a matter of time, as long as I give me enough time, these materials can be strengthened welded, do you want to learn?"

"Of course you want to learn, whoever doesn't want to learn is a fool!"

Everyone shouted.

"Okay, then let's start with the basics......!"

Du Xin is right, this kind of reinforced welding process is a process that Liu Lang learned at Stanford University, and it is also "high-tech" in the United States.

This technology was created by the islanders in the early eighties, and was first applied to the welding of car doors, the previous doors were a piece of material one-time lamination molding, although the integrity is very good, but because of the limitation of pressing molding, the strength of the material is relatively low, which has potential safety hazards.

Later, after countless experiments, the workers of Fengtian Company finally created a process that could enhance the strength of the weld, with this process, two relatively small pieces of high-strength material could be welded together, and the strength of the weld was higher.

In this way, the door of the wind field car is made of two or even three pieces of stronger materials, and the strength is greater, which shocked the Americans.

The American Automobile Industry Association wants to learn this technology, so it cooperates with Stanford University, and the person in charge of the university happens to be Professor Hans of materials engineering, although Liu Lang is not his student, but he often listens to his classes, the other party likes Liu Lang very much, and sometimes takes him to his own laboratory, this project is not very important, and the other party is not taboo, and tells Liu Lang a lot of test data.

Well, when it comes to data analysis, especially data analysis in mechanical engineering, there is no one stronger than Liu Lang in this world, even ordinary computers can't do it, because computers also need algorithms to analyze, Liu Lang himself is an expert, and his brain comes with various parameters.

After nearly half a month of calculation and analysis, Liu Lang restored this process technique.

It was only in the United States that he had no way to conduct tests, and after returning to China, he let the engineers of Huaxia Industrial Technology who were proficient in welding technology be restored, and Du Xin was one of the leaders.

Of course, although Liu Lang found out this process, it is not something that can be operated by a random welder, there are nearly ten kinds of techniques alone, and three of the welding techniques are at least sixth-level welders can master the technology.

If you want to learn this process, first of all, you must have superb welding technology, and secondly, you must know a lot of welding mechanisms, this process is not a simple craft, it has a deep theory behind it.

Of course, the welding process can not achieve strengthened welding, welding materials, steel heat treatment, annealing each link has accurate calculations, which link can not succeed, Du Xin was able to succeed just now because the material is only the most ordinary cast iron, if it is replaced with stainless steel materials, he will spend a lot of time.

This kind of technology has not yet appeared in China, and no one has even heard of it, but there is no doubt that this technology is of great significance to the country, because in many projects, especially in the construction of thermal power stations, the fan blades of large thermal turbines are manufactured at one time, and the largest fan blades can exceed one meter, and the same will also encounter the problems of Fengtian company, and the strength cannot reach the highest, so the life will be very short.

If this welding technique is used, then this problem will be solved, and even larger fan blades can be welded.

Of course, as Du Xin said, this process is more and more difficult with the material of the material, iron castings are the easiest, Du Xin took more than two months to learn, and now the most difficult in China is high-pressure pipes and turbine fan blades of large thermal power plant units, if you want to weld these materials Du Xin also spent half a year to learn.

The better the material, the higher the welding material, you can't always use ordinary welding rods when welding high-pressure pipe fittings, no material, no matter how good the process is useless.

In addition, high-strength material welding also involves argon arc welding, which is much more difficult than electrode arc welding, and few people can operate it in Fucheng.
