The information provided by Du Xiaodi gave Cao Guangshan a new inspiration. He started to study the steel plate tear again, and also contacted Cai Xingquan via long-distance phone number and asked him about relevant techniques. Cai Xingquan heard that Li Qingshan and Du Xiaodi were on the scene, and repeatedly said that these people were trustworthy, especially when he called Du Xiaodi "little girl" intimately. Those who didn't know thought Du Xiaodi was his junior relative.

Wang Jianguo's previous suggestion was ruthlessly ignored. Cao Guangshan, combined with Cai Xingquan's guidance, discussed with Li Qingshan, Du Xiaodi and others repeatedly and proposed a reliable welding plan, including using an electric grinding wheel to open two stress grooves near the weld, then preheat the welding points with an acetylene flame, and then welding while it is hot. After the welding is finished, you must tap the steel plate with a small hammer to release stress, etc.

Feng Xiaochen couldn't understand this set of craftsmanship, but he kept following everyone and did some work to fill in the gaps. Cao Guangshan's major was not welding. Some of the things he said were not in line with Li Qingshan, Du Xiaodi and others. At this time, Feng Xiaochen needed to coordinate in the middle and use language that both parties could understand to help them understand each other's meaning.

After the plan was discussed, Li Guoxing reported to the department again by phone. Dozens of experts organized by the Ministry of Machinery and the Ministry of Electricity were guarding the conference room of the Ministry of Machinery. After receiving the call, everyone held an emergency consultation and agreed that this was the best solution that could be achieved on the spot. So a deputy minister issued an order to start the repair to the site.

After this twists and turns, it was already dark. The train Feng Xiaochen and his friends were riding bypassing the accident site according to the adjusted operation diagram. Li Qingshan and his disciples and several other welders from other companies began to fight at night, taking turns around the breaking point of the steel plate. However, Du Xiaodi was the main player. She was petite and could squeeze into the middle of the workpiece to weld. The other male workers could get in, but it would be inconvenient to use their hands and feet. In addition, according to Li Qingshan, among his three proud disciples, Du Xiaodi was the most skilled. If it were others, he would not be relieved.

"Look at this girl, she is born to be a solder."

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

Feng Xiaochen smiled and said, "I think this little girl is not old, are there 20?"

"It's not yet. I just turned 18 this year." Li Qingshan said.

"I'm only 18 years old?" Feng Xiaochen was a little surprised. This girl wouldn't be a time traveler, right? If it weren't for the skills brought by her previous life, how could she have mastered such skills at such a young age?

Li Qingshan said: "Her father is my apprentice. He was an electric welder before, and later he worked as a riveter. That technique is one of the best in our factory. Unfortunately, in an accident, one of his hands was ruined and he couldn't do anything. At that time, this girl was only 14 years old, so she took over her father's class and went to the factory to apply to me. People say that she is a tiger father without a dog, and she is a tiger father without a dog. No matter how difficult the technique is, she can understand it at first sight and try it once.

Xiao Gao and Xiao Liu, both of them entered the factory at the age of 18. They studied with me for six or seven years, but were compared by this little girl. Last year, I took the three of them to the rescue of the Yuemahe Super Bridge. Professor Cai liked her very much and insisted on recognizing her as her kid. The steel beams of the bridge were welded, but others could not get into it, so she could get into it, so in the end she was mainly responsible for the welding. Experts from the Ministry of Railways took the flaw detector to test, and all the welds were level one."

"It seems that there are indeed geniuses in this world." Feng Xiaochen murmured.

Li Qingshan smiled and said, "Director Xiao Feng, I think you are also a genius. How many 20 yuan do you have this year?"

"Just over 20 years old." Feng Xiaochen said.

"Just just over 20 years old? It's amazing." Li Qingshan said, "I've just over 20 years old and I've been the director. I know Linbei Heavy Machinery, which is also of great technology. It's impossible for a person who has no chance to become the deputy director of Linbei Heavy Machinery. Let's just talk about the welding plan just now. I think you are quite professional. Although you are not in the welding industry, you will understand what's going on. It's really not easy."

"Master Li has been awarded the award. Actually, I have learned a lot from you." Feng Xiaochen said.

Tian Xing received instructions from the Ministry of Railways and learned that the department had given him a 48-hour emergency repair deadline and also issued an order to fully cooperate with the emergency repair work. He did not dare to neglect it, and he led a few people to find various tools and consumables for everyone. He also asked the passing trains to temporarily stop here and delivered hot rice and hot dishes.

The emergency repair was carried out until late at night. With the final weld completed, Li Guoxing announced that the emergency repair work was over successfully, and thunderous applause suddenly echoed. Li Guoxing, Shang Jinglun, Tian Xing, Ou Guisheng and others shook hands with the experts and workers participating in the emergency repair work one by one to thank them. Even Zhang Heping, who had been sleeping in the sleeper carriage, enjoyed the treatment of being warmly grateful. However, to be honest, Zhang Heping did make a contribution. He didn't run back and invited Professor Bao, Cao Guangshan, Li Qingshan and others. This person from Longshan Motor Factory alone would probably not be able to complete the work.

The welding work has been completed, but the effect is so good. We still need to wait for experts from the machinery department to come over to check. Only by ensuring that there is no problem with the weld, the train can be departed. However, unexpected situations arise. The plane the experts are riding in is affected by bad weather and cannot land at the airport closest to the emergency repair site. Instead, they are ready to land at another airport 7 oo kilometers away. From that airport to the emergency repair site, there is no direct train. If factors such as changing trains are considered, it will be at least 24 hours later for experts to arrive.

"This is really something that's happening!"

When Tian Xing heard the news, he was so anxious that he stomped his feet. The emergency repair work has only taken 12 hours so far, just within the time limit that Feng Xiaochen promised him, far ahead of the time limit allowed by the Ministry of Railways. If experts from the Ministry of Machinery can arrive at the time that was agreed in advance, then the clamping car has the hope to start early tomorrow morning, thereby reducing the road blockage time to within 24 hours, which will be a very perfect result.

The Ministry of Railways said that 48 hours of emergency repair time were allowed, but this was based on the suspension of a large number of freight trains. It can be said that every hour delay would result in hundreds of thousands of transportation losses. If Tian Xing could restore the line operation within 24 hours, it would be of great benefit to the smooth flow of the entire road network or Tian Xing's own political achievements. But who would have thought that a bad weather that was hundreds of miles away would disrupt Tian Xing's wishful thinking.

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

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

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

Li Qingshan didn't dare to say anything casually this time. He thought for a while before saying, "It's important to be a big deal. Please ask the leaders to make the decision on this matter."

Feng Xiaochen said: "The current situation is that experts with flaw detectors will have to wait at least one day and one night to come. If something happens in the middle, it may be delayed. You also know the significance of the Beijing Dragon Line. If a line is blocked, the entire northern road network will be completely in chaos. One hour will cost hundreds of thousands or even millions. If we are confident enough and have certain plans to allow the train to drive away, we can avoid these losses."

"That's right?" Li Qingshan thought for a while, nodded solemnly, "I can make this promise. There will be no major problems with the welds welded. If I want to drive, I can stay next to the arm and observe the situation of the welding joint at any time. If the situation is wrong, stop immediately, and there will definitely be no danger."

"If this is the case, that would be great." Feng Xiaochen said, "Let's go and talk to Director Li and the others together."

After hearing the plan mentioned by Feng Xiaochen and Li Qingshan, Li Guoxing, etc., they all scratched their heads a little.

There are certain risks when driving without flaw detection. If there is a problem with the quality of the weld, the arm tear up again, causing the stator to roll off and crush the flowers and plants on both sides, who will bear the responsibility?

But if we are just for the sake of safety, we will wait here for a day and a night, and the result of the flaw inspection may not be any problem, which is too unwilling to take the interests of the railway seriously. What's more, Longshan Motor Factory also hopes to drive early so that the stator can be transported to Hezhou Power Plant as soon as possible and reduce the time pressure during subsequent arrangements.

"I think we don't have to wait for the flaw detector. Master Li is experienced. Other welders on the scene have certain experience. Everyone's judgment of welding quality should be relatively reliable. In addition, by doing some strain measures, fixing the stator with sleepers, so that even if the arm cracks again, as long as it can stop in time, it can ensure that the stator will not roll off the frame. Also, Master Li said that he can escort the vehicle with the vehicle and observe the situation of the weld at any time, and stop the train before the weld cracks. In this way, we basically have no risks." Feng Xiaochen said to everyone.

"What about everyone's opinions?" Li Guoxing looked at everyone and asked.

“I support it in principle!”

"I think it can be a try!"

"Go a bet, I think it's reliable..."

Everyone expressed their opinions. After listening to everyone's opinions, Li Guoxing thought for a while and said:

"Okay, I'll ask the Ministry for instructions and see what the Ministry is determined." (To be continued.)8
