The information provided by Du Xiaodi gave Cao Guangshan a new revelation.He resumed researching the tearing of the steel plate, and also contacted Cai Xingquan through a long-distance phone call and asked him about the relevant technology.Cai Xingquan heard that Li Qingshan and Du Xiaodi were at the scene, and even said that these people could be trusted, especially for Du Xiaodi, who called a "little girl" and was very close, and did not know what kind of relatives Du Xiaodi were his descendants.

Wang Jianguo's previous suggestions were ruthlessly ignored by everyone, Cao Guangshan combined with Cai Xingquan's guidance, and Li Qingshan, Du Xiaodi and others repeatedly discussed, put forward a reliable welding program, including using electric grinding wheel to open two stress groove near the weld, and then preheating the solder joint with acetylene flame, and then welding while hot, after welding, after welding, it is necessary to use a small hammer to knock the steel plate to release stress.

This set of technology Feng Xiaochen also can not understand, but he has been following the people, to do some work to pick up the gaps.Cao Guangshan's profession is not welding, he said that some things with Li Qingshan, Du Xiaodi they are not, at this time, Feng Xiaochen needs to coordinate in the middle, in a language that both sides can understand to help them understand each other's meaning.

After the plan was discussed properly, Li Guoxing once again reported to the Ministry by telephone.Dozens of experts organized by the Ministry of Machinery and the Ministry of Electricity were stationed in the conference room of the Ministry of Machinery, and after receiving the phone call, everyone held emergency consultations and agreed that this was the best solution that could be done on the spot, so a deputy minister issued an order to the site to start repair.

After this twist, the sky has darkened, Feng Xiaochen their original train has been based on the adjusted operating chart around the accident location.Li Qingshan with a dry apprentice and several other enterprises of the welder began to fight at night, around the steel plate fracture point in turn.However, the main force is Du Xiaodi, her body is relatively small, can squeeze into the middle of the workpiece to weld, other male workers can drill in, but then want to play hands and feet is very inconvenient.In addition, according to Li Qingshan, among his three proud students, he also had to count Du Xiaodi's most exquisite technology, and he did not dare to be reassured by others.

"Look at this girl, she was born with electric welding."

Li Qingshan stood under the car, looked at Du Xiaodi's welding gun from time to time burst out of the welded flowers, and proudly said to Feng Xiaochen.

Feng Xiaochen smiled, “I don’t think this little girl is too old, is there 20?”

"Not yet, this year I'm just 18 years old."Li Qingshan Road.

“Only 18 years old?”Feng Xiaochen was somewhat surprised, this girl will not be a crosser, if not the technology brought by the previous life, how can it be so young to practice such a skill.

Li Qingshan said: "Her father is my apprentice, previously a welder, and later also worked riveting, that technology, in our factory is also one of the best."Unfortunately, in an accident, one of his hands was scrapped and nothing could be done.At that time, the girl was only 14 years old, and she put her father's class into the factory and apprenticed with me.People say that the tiger father has no dog, she is the tiger father dog.It’s hard to see the technology, she’ll understand it, try it once.

Xiao Gao and Xiao Liu, both of them, entered the factory at the age of 18, and I also studied for six or seven years, and were compared by this little girl.Last year, the Prancing Horse River Bridge was in danger, and I took the three of them, and Professor Cai liked her very much, and had to recognize her as a dry girl.The bridge steel beam welding, others can not drill in, is she can drill in, so in the end is mainly responsible for welding out.The experts of the Ministry of Railways tested with the flaw detector, and all the welds were first-class.”

“There seems to be a genius in this world.”Feng Xiaochen murmured.

Li Qingshan smiled, “Director Xiao Feng, I think you are also a genius, how many are you this year?”

“I was just 20 years old.”Feng Xiaochen said.

Just 20 years old?What a great thing.Li Qingshan said, “Just over 20 years old is the director.”I know that the technology is also top-down, and people who don't have two sons can't be deputy director in Linbei heavy machine.Let's say we just discussed the welding program, I think you are very professional, although not dry welding this line, but what you can understand, this is not easy."

"Master Li has won the award, in fact, I have learned a lot from you."Feng Xiaochen said.

Tian Xing received instructions from the Ministry of Railways, learned that the Ministry gave a 48-hour repair time limit, but also gave him the order to fully cooperate with the repair work, he did not dare to slack off, with a few people busy before and after to find a variety of tools, consumables, but also let the passing train stop here temporarily, sent hot meals hot dishes.

This repair was done until late at night.With the completion of the last weld, Li Guoxing announced that the repair work was successfully completed, and the scene suddenly sounded thunderous applause.Li Guoxing, Shang Jinglun, Tian Xing, Ou Guisheng and other experts and workers who participated in the repair work shook hands one by one to thank, and even Zhang Heping, who had slept in the sleeper compartment, also enjoyed the treatment of being warmly thanked.However, to say, Zhang Heping is indeed indispensable, not that he ran back to ask Professor Bao, Cao Guangshan, Li Qingshan and others, just because of this man of Longshan Electric Factory, I am afraid that he could not complete this work.

Welding work is completed, but the effect, but also need to wait for the mechanical department experts to carry the flaw detector to test, only to ensure that the weld is no problem, can the start of the car.However, the unexpected situation occurred, and the plane on the experts encountered the impact of bad weather, and it was impossible to land at the nearest airport to the scene of the repair, but was ready to be reduced to another airport 700 kilometers away.From that airport to the repair site, there is no direct train, if you consider the change of car and other factors, experts arrived at least 24 hours later.

“Anything really catches up!”

Heard the news and was in a hurry to get on his feet.So far, the repair work has only taken 12 hours, just in time that Feng Xiaochen promised him, far ahead of the time limit allowed by the Ministry of Railways.If the experts of the mechanical department can arrive at the pre-speaked time, then the clamp truck has the hope of starting tomorrow morning, so that the time of road obstruction can be reduced to within 24 hours, which will be a very perfect result.

The Ministry of Railways said that there is a 48-hour rush time, but this is based on the suspension of a large number of freight trains.It can be said that every delay of one hour is hundreds of thousands of transport losses.If Tian Xing can resume the operation of the line within 24 hours, it will be of great benefit to the smooth flow of the entire road network or the performance of Tian Xing himself.But who had thought that a bad weather hundreds of miles away had disrupted Tian Xing's plan.

Seeing this situation, Feng Xiaochen quietly pulled Li Qingshan aside and asked in a low voice: "Master Li, are you sure of the quality of welding?"

Li Qingshan paused for a moment and replied, "I can be 80% sure."

"If that's the case, then we don't do the flaw detection and drive directly, do you think there is a problem?"Feng Xiaochen asked again.

Li Qingshan did not dare to speak casually this time, he thought for a while, only to say: "It is a matter of great importance, this matter or please let the leaders take charge."

Feng Xiaochen said: "Now the situation is that experts with flaw detectors must have at least one day and one night to come over, in case something happens in the middle, maybe they will have to delay."The meaning of the Jinglong line is also clear, a line blocked, the entire northern road network is completely messy, an hour is hundreds of thousands or even millions of losses.If we are sure enough, and if we have a certain plan to let the train go, we can avoid these losses.”

“Is that so?”Li Qingshan thought for a moment and nodded solemnly: "I can play this package ticket, the welded welded, there will be no big problem."If I want to drive, I can stay next to that arm and observe the solder joint at any time.If the situation is found to be wrong, stop immediately, there will be no danger.”

"If so, that would be great."Feng Xiaochen said, "Let's go and talk to Li's director together."

Li Guoxing, Shang Jinglun and others listened to Feng Xiaochen and Li Qingshan's plan, and their heads were scratched.

Driving without detection is risky.If there is a problem with the quality of the weld, the arm is torn again, causing the stator to roll down and crush the flowers and plants on both sides, who will bear the responsibility?

But if in order to be safe, everyone is foolish to wait here for another day and one night, and the results of the flaw may not be any problem, which is too much to pay attention to the interests of the railway.What's more, Longshan Electric Factory also hopes to drive early, so as to transport the stator to the Hezhou power plant as soon as possible, and reduce the time pressure when the follow-up arrangement.

“I don’t think we have to wait for the flaw detector.Master Li is rich in experience, other welders on the spot also have some experience, everyone's judgment of welding quality should be more reliable.In addition, we can also do some strain means, with a sleeper to fix the stator, so that even if the arm is cracked again, as long as it can stop in time, it can also ensure that the stator will not roll off the frame.In addition, Master Li said that he could escort the car, observe the situation of the weld at any time, and stop the train before the weld cracks, so that we are basically no risk."Feng Xiaochen said to the people.

“What about everyone’s opinion?”Li Guoxing looked at the people and asked.

“I support it in principle!”

“I think I can try!”

“I bet you, I think it’s worth it.”

People are talking.Li Guoxing listened to the opinions of the people, thought for a while, and said:

"Well, I'll ask the Ministry again to see how determined it is."(Not completed.)
