"Mr. Liu, the work is done, how about you take a look?"

Ma Ming clapped his hands and asked.

Liu Lang nodded.

"Perfect! Feng Lao, we have completed the welding, let's do a destructive test to see if our technology is up to standard!"

"Amazing, Liu Lang, these three workers of yours are really powerful, they are all eighth-level welders, right?"

"We're only Level 5 workers!"

Ma Ming walked over and said.

"Level 5 worker? Your level is only level 5 worker, how is it possible?"

If this level is a fifth-level worker, how can the seventh- and eighth-level workers present be embarrassed?

"They were fifth-level workers two months ago, but now! There is no problem with eighth-level, and the factory will promote them in the New Year!"

Liu Lang replied.

"Two months ago, you were still a level 5 .........?"

The people present were a little shocked, the skills of these three people improved a little fast, right?

"We use the best equipment in our factory, we have a digital display intermediate frequency furnace imported from the United States, as well as several digital display machine tools, material detectors, and material tubes......... The most important thing is that there are a group of best experts who train every day, Professor Xiong teaches us hand in hand, and Mr. Liu, his level is the first in China, if we don't learn well, there will be no reason!"

Ma Ming: They are very proud now, they don't feel anything in the factory, and they are used to using the best equipment in China every day, but when they go to Jibei, they see that this is not the case at all.

There are two ways, one is to teach by teachers, for example, many factories are old workers with new people, and then continue to practice in the work, if the old workers think that the new person is good, then teach him some experience, if he thinks he can't do it, I'm embarrassed, while playing!

This method is completely impossible in the North Industries Group, not to mention Professor Xiong, even Liu Lang will also teach his own experience, of course, whether you can learn it depends on yourself, but Liu Lang will simplify the complicated and cumbersome process to the greatest extent, so that people can understand it as soon as they hear it.

Then it's practice, which doesn't say, it's practice practice and practice, but how to practice then pay attention to the method, first of all, the tool of practice, the tool will not make the result greatly discounted, and then the method of practice, simply put, to strengthen yourself in the most scientific way.

Liu Lang's invention of a scientific practice method, can practice the brain reaction of employees and the coordination of hands and feet, such as riding a bicycle with the right hand on the handlebar, left hand on the right handlebar, which will quickly improve people's coordination, these seem to be small skills, but the training of the brain is very effective, for the use of the brain this magical organ, Liu Lang is the most vocal, he himself is an example of brain development to the limit of human beings.

With the teaching of famous teachers, coupled with the best equipment and the best training methods, the ability of the workers has improved rapidly in just two months, and many people feel that they have learned more skills in these two months than they have learned in the previous years.

"What? Your factory has an intermediate frequency furnace, a digital display machine tool, how is it possible?"

Feng Liyong was a little dazed.

"I bought these when I was in the United States!"

"Bought in the U.S., and they're going to sell us these devices?"

Of course, Feng Liyong didn't believe it.

"Hehe, Old Feng, let's not talk about this, the pipe fittings are all welded, give it a try!"

As far as Feng Liyong's big mouth is concerned, if he knew how Liu Lang bought these devices, it wouldn't be noisy all over the world!

"Okay, okay, then......... Director Zhao, let's test this steel pipe!"

At this time, Zhao Yongsheng was also a little excited, he felt that Liu Lang was not talking nonsense, just the level of these three workers, and the level of his factory was also top-notch, if Liu Lang was nonsense, could he send these three first-class workers?

Could it be that they really have mastered this magical craft?

"Quick, you two take this pipe to the third workshop, quick!"

Zhao Yongsheng pointed at the two and shouted, and the two workers hurriedly ran over and lifted the pipe, and then walked to another workshop with everyone.

Put the tube into the test instrument, fill the hydraulic oil and start the instrument ten minutes later.

This instrument does not have any digital display system, and can only rely on material data for testing, for example, the stress limit of the 304 model steel is about 4,000 tons of hydraulic press stamping, of course, the same material flaw detection experiment with different diameters and different wall thicknesses is also different.

According to the diameter and wall thickness of this steel pipe, the flaw detection limit is about 3,500 tons of stamping, and the operator will constantly pressure the instrument.

After about ten minutes, the pressure value on the instrument panel exceeded three thousand tons, and the huge hydraulic compartment began to tremble slightly, making a low roar.

Zhao Yongsheng and these people are accustomed to it, this hydraulic press can reach a maximum of 5,000 tons, which is produced by Henan Heavy Machinery Factory, and it can shake the ground out of the gap when it runs to the highest peak.

Now there are the best stamping machines in China that can reach more than 10,000 tons, and can change the diameter of stainless steel pipes with a diameter of more than one meter, but such a large stamping machine is imported from the island country, and the price is more than 6 million yuan, and there are only six or seven units in the country, three in Shencheng and none in Jibei Province.

When it exceeded 3,600 tons, a muffled sound was heard from the instrument, and the stress of the steel pipe wall could not withstand the huge pressure and was torn apart.

"Okay, start lowering the pressure!"

Zhao Yongsheng shouted at the operator, and the other party hurriedly pressed the button.

After a minute, the machine fell completely silent.

The steel pipe was torn open with a 10-centimeter-long crack about 30 centimeters from the weld.

If the welded steel pipe is tested, the crack will be produced in the weld, because the force of the steel pipe in the test chamber is uniform, the crack must be in the weakest stress place, the weld is equivalent to the scar of the pipe, no matter how good it is repaired, the internal damage will be received, which is the most basic criterion of welder technology, but now, this criterion has been broken.

"Also......... It's .........!"

Whether it is the experts of the Ministry of Electric Power or Zhao Yongsheng, their thinking is a little frozen, and they are all thinking: How is this possible?

But no matter how impossible, the facts are in front of us, and it's true.

"Everyone, this is only the compression test, you can also test the torsion, acid resistance and other indicators, these data will not be lower than the original material, of course, the biggest advantage of this process is the compression, the pressure resistance at the weld is about 10% higher than other positions!"

"Liu Lang, how did you do it?"

Feng Liyong asked excitedly.
