"Perfect! Mr. Feng, we have completed the welding. Now let's do a destructive test to see if our technology is up to standard!"
"Awesome, Liu Lang, these three workers of yours are really awesome. They are all level 8 welders, right?"
"We are only level five workers!"
Ma Ming came over and said.
"Level 5 worker? Your level is only level 5 worker? How is that possible?"
If this level is a fifth-level worker, how can it be so embarrassing for those seven-level and eighth-level workers present?
"They were Level 5 workers two months ago, but now! There is no problem with Level 8 workers. After the new year, the factory will promote them!"
Liu Lang replied.
"Two months ago, I was still a Level 5 worker...?"
The people present were a little shocked. Didn't the skills of these three people improve a bit quickly?
"Our factory uses the best equipment, including a digital display medium frequency furnace imported from the United States, several digital display machine tools, material detectors, and enough material tubes... The most important thing is that there is a team of
The best experts train every day, Professor Xiong teaches us step by step, and Mr. Liu, his level is the best in the country. It will be unreasonable if we can't learn well!"
Ma Ming and the others are very proud now. They have no feeling in the factory. They are used to using the best equipment in the country every day. But when they go to Jibei, it is not like this at all. What kind of equipment does this power plant use?
Is it corny? Is this a human thing?
How to train talents? There are two ways. One is to teach by teachers. For example, in many factories, old workers lead new people and then practice them continuously at work. If the old workers think that the new people are good, they will teach them some experience. If they think that they are not good, they will teach them.
, sorry, let’s go and play!
This method is completely impossible in Norinco. Not to mention Professor Xiong, even Liu Lang will teach everything he has learned. Of course, it’s up to you whether you can learn it, but Liu Lang will learn the complicated skills
The tedious process is simplified to the greatest extent so that people can understand it at a glance.
Then it’s practice. It’s hard to say, just practice, practice and practice. But how to practice depends on the method. The first is the tool for practice. If the tool is not good, the result will be greatly compromised. Then there is the method of practice. To put it simply,
Use the most scientific method to strengthen yourself.
Liu Lang invented a scientific exercise method that can train employees' brain reactions and hand-foot coordination. For example, when riding a bicycle, use your right hand to hold the handlebar and your left hand to hold the right handlebar. This will quickly improve people's coordination ability.
These may seem like small tricks, but they are very effective in training the brain. Regarding the use of this magical organ, the brain, Liu Lang has the most say. He himself is an example of a brain that has been developed to the limit of human beings.
With the guidance of famous teachers, coupled with the best equipment and the best training methods, the workers' abilities have improved rapidly in just two months. Many people feel that the skills they learned in these two months are better than those they learned in years before.
They have learned a lot, and they still can't see the difference between them, but compared with other factories, it is immediately obvious, and the difference is not even a little bit.
"What? Your factory has an intermediate frequency furnace? A digital display machine tool? How is that possible?"
Feng Liyong was a little confused.
“I bought these when I was in the United States!”
"Bought in the United States? Will they sell us these devices?"
Of course Feng Liyong didn't believe it.
"Haha, Mr. Feng, let's not talk about this anymore. The pipe fittings are all welded. Let's give it a try!"
If Feng Liyong, that big talker, knew how Liu Lang bought these devices, he would make a fuss all over the world!
"Okay, okay, then...Director Zhao, let's put this steel pipe to the test!"
At this time, Zhao Yongsheng was also a little excited. He felt that Liu Lang was not talking nonsense. The level of these three workers alone was top-notch in his factory. If Liu Lang was talking nonsense, could he send these three first-class workers?
?
Could it be that they really mastered this magical craft? If so, it would be a big deal!
"Quick, you two take this pipe to the third workshop, quick!"
Zhao Yongsheng pointed at the two men and shouted, and the two workers hurried over to lift the pipe, and then followed everyone towards another workshop.
Put the tube into the test instrument, fill it with 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 304 model steel is about 4,000 tons of hydraulic press. Of course, the same material with different diameters and different wall thicknesses can be tested.
The experiments are also different.
Based on the diameter and wall thickness of this steel pipe, the flaw detection limit is probably 3,500 tons of stamping, and the operator will continue to pressurize the instrument.
About ten minutes later, the pressure value on the instrument panel exceeded 3,000 tons, and the huge hydraulic tank began to vibrate slightly and made a low roar.
People like Zhao Yongsheng are used to it. This hydraulic stamping machine can reach a maximum capacity of 5,000 tons. It is produced by Henan Heavy Machinery Factory. When it reaches its highest peak, it can shake out gaps in the ground.
At present, the best stamping machines in China can reach more than 10,000 tons and can reduce the diameter of stainless steel pipes with a diameter of more than one meter. However, such a large stamping machine is imported from the island country and costs more than 6 million yuan. The total number in the country is only
There are six or seven stations, including three in Shencheng and none in Jibei Province.
When it exceeded 3,600 tons, a muffled sound was heard from the instrument. The steel pipe wall could not withstand the huge pressure and was torn apart.
"Okay, let's start reducing the pressure!"
Zhao Yongsheng shouted to the operator, who quickly pressed the button.
After a minute, the machine went completely silent.
A ten centimeter long crack was torn in this steel pipe, about thirty centimeters away from the weld.
If a destructive test is performed on a steel pipe made of a single piece of material, cracks will occur randomly. If a welded steel pipe is tested, the cracks will definitely occur at the weld, because the force on the steel pipe is uniform in the test chamber, and the cracks must be at
Where the stress is weakest, the weld is equivalent to a scar on the pipe. No matter how well it is repaired, internal damage will occur. This is the most basic rule of welder technology, but now, this rule has been broken.
"It's...it's really...!"
Whether it is the experts from the Ministry of Electric Power or Zhao Yongsheng, their thinking is somewhat frozen. They are all thinking: How is this possible?
But it is no longer possible, the fact is before our eyes, it is true.
"Everyone, this is just a compression test. You can also test it for torsion resistance, acid resistance and other indicators. These data will not be lower than the original material. Of course, the biggest advantage of this process is compression resistance.
The pressure resistance of the weld is about ten percent higher than that of other locations!"
