Listening to Wang Jianguo squatted in the car to talk about his master, Du Xiaodi, an 18-year-old female welder of Tongyuan boiler Factory, had long been angry under the car.She is one of the three apprentices Li Qingshan took to Beijing to participate in the welder competition, the other two are male workers, the age is older, is Du Xiaodi's brother.

Just now, when everyone came all the way from the bus, Wang Jianguo gathered around a few of them to talk about how capable they were, and also "Xiaodi" long "Xiaodi" talked to her for a short time, once said to ask her to go to the mountain province to ride, a chance to say that there is a chance to teach her a few hand welding tricks, three sentences upside down two words is the gymnasium beam that the ass.

Feng Xiaochen did not hear the words in front of him, and did not know what happened to the gymnasium beam.Du Xiaodi and Li Qingshan have long known that it is actually an ordinary steel beam, and the load-bearing is tens of tons.As for the province only chose Wang Jianguo to weld this steel beam, on the one hand, Wang Jianguo is indeed a little technical, not a false name, on the other hand, because Shanbei Province itself is only an agricultural and animal husbandry-based province, the number of subordinate industrial enterprises in the province, locality and county levels is not as good as the number of enterprises in a city in Tongyuan City.Wang Jianguo can feel that Laozi is the first in the world in the mountains, because there are no tigers in the mountains.

Wang Jianguo in front of Du Xiaodi line to play talent reasons, Du Xiaodi and her brothers Gao Liqian, Liu ambition are like a mirror, that is because Du Xiaodi is beautiful, this Wang Jianguo must be moved.Just now, Gao Liqian and Liu Xiong stood under the car, squinting at Wang Jianguo, whispering about cutting this boy into a few pieces to be more hateful, they have even discussed whether they are using a shear machine or directly to do gas cutting, the only uncertainty is that the skin is so thick, with ordinary equipment in the end can not be cut.

Hearing the master's call, Du Xiaodi rushed forward, jumped on the straight, and jumped on the clamp truck.Wang Jianguo saw the beauty come up, his heart was happy to open flowers, and hurriedly gave up a position, wanting Du Xiaodi to squat beside him.Du Xiaodi would be willing to stick together with him, directly squeezed into the middle of Li Qingshan and Feng Xiaochen, but did not expect that this would just become face-to-face with Wang Jianguo.The two bouquet of thieves' eyes almost stuck in her face, making her feel as if she were disgusted by a drop of bird droppings.

“Xiao Di, look at this rift, it doesn’t look like the one on the Prancing Horse River Bridge?”Li Qingshan did not notice Wang Jianguo's performance, he pointed to the crack and said to Du Xiaodi.

Du Xiaodi looked at Wang Jianguo in a busy way, then took a magnifying glass from a kit on his back, approached the parts of the rift, and nodded and said, "I think it's very similar, you see, this is the flake structure of Professor Cai."

“What do you mean?”Feng Xiaochen asked.

Du Xiaodi turned to look at Feng Xiaochen, and looked back at Li Qingshan, not knowing whether he should explain to Feng Xiaochen.Li Qingshan said: "Feng is a technical expert, you talk to him about the last situation, let him help determine."I don't remember much about Professor Tsai's, if you remember well, just say it."

“Well, all right.”Du Xiaodi was obviously quite respectful of his master, she turned around, pointed to the rift, and said to Feng Xiaochen: "Chief Feng, look at the cracking situation of metal on this crack, can you see that there is a vertically organized crack?"This kind of cracking, called layer-like tearing, that is, this steel plate is actually stacked layer by layer, and the stator behind it rushes forward, and the steel plate is torn into several layers, because each layer is not as thick as it used to be, and it will be disconnected and become what it is now."

“Dad, that’s what you say, isn’t it?This is obviously a piece of steel, where is there a layer of layer?"Wang Jianguo said.

Many people did not pay attention to him, Feng Xiaochen took Du Xiaodi's magnifying glass, carefully recognized it, nodded: "It is a little of this feeling, I think I still ask Cao to see, he is an expert in metal materials, must know this more."

Feng Xiaochen said that Cao Gong refers to Cao Guangshan, deputy chief of the Jiangcheng Iron and Steel Factory, who has just been on the fissure in the car for visual identification, and judged that there may be defects when forging.Hearing Feng Xiaochen call him, he stepped on the iron ladder by the side of the car and came to the cracked arm.

In such a small place, it is difficult to get more people.Feng Xiaochen handed Wang Jianguo a sign of the look, Wang Jianguo paused, and finally stood up unwillingly, giving up the position to Cao Guangshan.Just now, Feng Xiaochen introduced himself to everyone, and Wang Jianguo knew that he was a deputy director in a large enterprise, and his heart was somewhat timid.He can not put Li Qingshan such as the eight-level seniors in the eyes, but dare not provoke Feng Xiaochen such a powerful, which is also a kind of public do not fight with the official performance.

“You say this is a layered tear?I’ve heard that, but I haven’t seen it specifically.“Little Master, who are you listening to this concept?”After Cao Guangshan looked at the crack with a magnifying glass, he asked Du Xiaodi.

Du Xiaodi said, “Professor Cai of Beijing University of Technology, and I don’t understand.”

“Professor Tsai?“Professor Tsai Xingquan?”Cao Guangshan asked.

“Yes, it is him.”Du Xiaodi Dao.

“Do you know him?”Cao Guangshan asked in amazement.Professor Cai Xingquan is famous in the field of metal materials, Cao Guangshan has played with him several times, and he is not familiar with it, but he is quite admired for his talent.Now I heard that this little girl in front of her actually knew Cai Xingquan, and he could not help but be surprised.

Li Qingshan said next to him: "Last year, there was a danger in the province of Prancing Horse River Bridge, and the steel beams were cracked, and I took a few of them to participate in the repair.At that time, the province invited Professor Cai to do analysis, and the layer-shaped tearing was what he said.”

"That's it, I know it."Cao Guangshan had a look of surprise on his face and said, "The Prancing Horse River Bridge is a very legendary thing in our industry."Using welding to repair the steel structure of the overloaded bridge is an initiative.Yes, I remember that at that time, I was responsible for the welding of steel beams, a female worker under 20 years old, is it you?”

Speaking of this, he looked at Du Xiaodi, his eyes full of admiration.

Du Xiaodi, who was just talking about it, suddenly nodded, and her face also passed a red halo, and she said with a low head: "The province asked my master to weld, but the space under the bridge is too small, my master and my two brothers can't go in, only I can drill in, so let me go."

“Wonderful, great!Reload the bridge, I heard that it is still welded, you are such a little girl... Yi, Master Li, you are really a famous teacher out of the apprentice ah!"Cao Guangshan praised it.Outsiders see the lively, inside the doorway, how difficult a thing, the layman may not see, but the people in the circle are aware of it.Cao Guangshan did not personally participate in the Prancing Horse River Bridge rescue, but he heard some of the industry's peers talk about some technical details, and he could imagine the difficulty.

Feng Xiaochen couldn't help but turn his head to look at Wang Jianguo, and saw that the muscles in his face were already somewhat stiff, and the eyes that were burning just now staring at people's sister paper suddenly became dim.

What is a face-to-face face, this is called a face-to-face face!

He had just boasted with people all the way that he had welded a steel beam in the gymnasium, and also said that he would teach Du Xiaodi a few strokes, but he did not know that people played more than ten times as long as he wanted.Welding traffic heavy containing the car of the bridge steel beam, even the vice president of the Jiangcheng steel plant in the family are amazed at their own technology, he Wang Jianguo's two sons are enough to show in front of people?

Most importantly, they were a lesbian, and they were seven or eight years younger than him.In the past seven or eight years, Wang Jianguo has just begun to learn whether electric welding is good, but the little girl has been able to stand alone.

Cao Guangshan sighed and returned to the original topic, and he asked, “Did Professor Cai say in detail what happened to this layer-shaped tear?”

Du Xiaodi: “He said it.Listening to him, this layer-shaped tear has been studied in few people in the past because it happens much less than other cracks.He said that the International Welding Society has conducted case studies since the early 1970s, and only 22 cases have been counted since last year.He said that the reason for this situation is that the casting steel ingots is mixed with bubbles or other impurities, and when the rolled steel, these bubbles or impurities are pressed into strips, resulting in mezzanines in the material.The steel that rolled out in this way looks like a whole piece, but it is actually a layer of structure.

Cao Guangshan himself engaged in steel, and he understood what was going on.Du Xiaodi's narrative is somewhat inaccurate, it is estimated that it is not very understanding Cai Xingquan's explanation, and it may be that Cai Xingquan deliberately said more popularly when he explained it.Cao Guangshan combined with his own knowledge analysis to know the principle, he even nodded: "reasonable, reasonable, from the shape of the crack, indeed in line with this layer tear situation."So, Xiaodu, was the case with the last Prancing Horse River Bridge, too?”

"That's it."Du Xiaodi answered.

"That is to say, your last repair plan can be used on this time?"Cao Guangshan said again.

The force of the railway bridge will not be smaller than the current hydraulic pole arm, and the vibration generated by the high speed of the train is also much larger than the vibration of the clamp truck running smoothly at a speed of 40 kilometers per hour.In addition, the restoration of the Prancing Horse River Bridge is intended for long-term use, and this time, the repair of the clamp truck only needs to cope with the transportation of the next few hundred kilometers.If the last repair solution is feasible, then this time according to the hoist painting, it should be no problem.(Unfinished.)
