The information provided by Du Xiaodi gave Cao Guangshan a new enlightenment. Pen & Fun & Pavilion www.biquge.info he started to study the tearing of steel plates again, and at the same time contacted Cai Xingquan through a long-distance phone call and asked him about the relevant techniques. Cai Xingquan heard that Li Qingshan and Du Xiaodi were at the scene, and said that these people can be trusted, especially for Du Xiaodi, he called a "little girl" affectionately, and he didn't know that Du Xiaodi was his junior relative.

Wang Jianguo's previous suggestions were ruthlessly ignored, Cao Guangshan combined with Cai Xingquan's guidance, and Li Qingshan, Du Xiaodi and others repeatedly discussed, put forward a set of reliable welding schemes, including using an electric grinding wheel to open two stress grooves near the weld, and then using acetylene flame to preheat the weld joint, and then welding while it is hot, and after the welding is completed, it is necessary to hit the steel plate with a small hammer to release the stress and so on.

Feng Xiaochen couldn't understand this set of craftsmanship, but he still kept following everyone and doing some work for everyone to fill in the gaps. Cao Guangshan's profession is not welding, there are some things he said that are not compatible with Li Qingshan and Du Xiaodi, so Feng Xiaochen needs to coordinate in the middle and use a language that both parties can understand to help them understand each other's meaning.

After the plan was properly discussed, Li Guoxing once again reported to the ministry by telephone. Dozens of experts organized by the Ministry of Machinery and the Ministry of Electric Power were in the conference room of the Ministry of Machinery, and after receiving the call, everyone had an urgent consultation, and agreed that this was the best plan that could be done on the spot, so a deputy minister issued an order to the site to start repairing.

After all these twists and turns, the sky has already darkened, and the train Feng Xiaochen and the others were originally on have already bypassed the accident site according to the adjusted running map. Li Qingshan took a group of apprentices and several other welders from other companies to start a night battle, taking turns around the fracture point of the steel plate. However, Du Xiaodi is the main force, she is relatively petite and can squeeze into the middle of the workpiece to weld, and other male workers can get in, but it is very inconvenient to use their hands and feet. In addition, according to Li Qingshan, among his three proud disciples, Du Xiaodi is the most skilled, and he doesn't dare to rest assured if he is replaced by others.

"Look at this girl, she was born to burn electric welding. ”

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

Feng Xiaochen smiled: "I don't think this little girl is very old, is there 20?"

"Not yet, I just turned 18 this year. Li Qingshan said.

"Only 18 years old?" Feng Xiaochen was a little surprised, wouldn't this girl also be a traverser, if it wasn't for the technology she brought from her previous life, how could she have practiced such skills at such a young age.

Li Qingshan said: "Her father is my apprentice, he was a welder before, and later he also worked as a riveter, and that technology is also one of the best in our factory." It's a pity that in an accident, one of his hands was useless, and he couldn't do anything. At that time, this girl was only 14 years old, so she entered the factory with her father's class and apprenticed with me. People say that the tiger father has no dog, and she is a tiger father and no dog girl. No matter how difficult the technique is, she can understand it at a glance, and she will try it once.

Xiao Gao and Xiao Liu, both of them, entered the factory at the age of 18, and they also studied with me for six or seven years, and they were stunned to be compared to this little girl. Last year, when the Yuema River Bridge was rescued, I took the three of them there, and Professor Cai liked her very much, and he had to recognize her as a goddaughter. The steel girder of the bridge is welded, and others can't get into it, but she can get into it, so in the end, she is mainly responsible for welding. Experts from the Ministry of Railways went to measure with flaw detectors, and all welds were grade 1. ”

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

Li Qingshan smiled: "Director Xiao Feng, I think you are also a genius, you are in your 20s this year?"

"Just over 20 years old. Feng Xiaochen said.

"Just over 20? Li Qingshan said, "Just over 20 years old, he is the director." Lin Bei Heavy Machinery I know, the technology is also top-notch, no one who has two ideas, it is impossible to be the deputy director of Lin Bei Heavy Machinery. Let's just say that we just discussed the welding plan, I think you are quite professional, although you are not in the welding industry, but you can understand what you hear, this is really not simple. ”

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

Tian Xing received instructions from the Ministry of Railways, and learned that the ministry gave him a 48-hour time limit for emergency repairs, and at the same time gave him an order to fully cooperate with the repair work.

This rush repair lasted 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 resounded with thunderous applause. Li Guoxing, Shang Jinglun, Tian Xing, Ou Guisheng and others shook hands with the experts and workers who participated in the emergency repair work one by one and thanked them. However, to put it mildly, Zhang Heping did make a great contribution, if he didn't go back and invite Professor Bao, Cao Guangshan, Li Qingshan and others, I am afraid that this work would not be able to be completed by relying on this cadre of Longshan Electric Machinery Factory.

The welding work is completed, but the effect is still to wait for the experts of the mechanical department to come to the inspection with a flaw detector, and only when the weld is sure that there is no problem, can the car be shipped. However, the unexpected happened, the plane in which the experts were flying was affected by bad weather and could not land at the nearest airport to the repair site, but was diverted to another airport 700 kilometers away. There was no direct train from that airport to the repair site, and if you consider factors such as changing trains, it would be at least 24 hours before the experts arrived.

"It's really a catch-up!"

When Tian Xing heard the news, he was so anxious that he stomped his feet. So far, the emergency repair work has only taken 12 hours, which is exactly within the time frame promised to him by Feng Xiaochen, far ahead of the time limit allowed by the Ministry of Railways. If the experts of the mechanical department can arrive at the predetermined time, then there is hope that the clamp truck will be started early tomorrow morning, so that the road jam time will be reduced to less than 24 hours, which will be a very perfect result.

The Ministry of Railways said it would allow 48 hours for emergency repairs, but this was based on the suspension of a large number of freight trains. It can be said that for every 1 hour of delay, there are hundreds of thousands of transportation 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 and Tian Xing's own political achievements. But who would have thought that a bad weather hundreds of miles away would disrupt Tian Xing's wishful thinking.

Seeing this situation, 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 eighty percent sure." ”

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

Li Qingshan didn't dare to say anything casually this time, he thought for a while before he said: "The stakes are very high, and the leaders should be in charge of this matter." ”

Feng Xiaochen said: "The current situation is that it will take at least a day and a night for the experts with the flaw detector to come over, and if something happens in the middle, it may be delayed." You are also clear about the significance of the Jinglong line, if a line is blocked, the entire northern road network will be completely chaotic, and an hour is hundreds of thousands or even millions of losses. If we are sure enough and have a certain plan to get the train to go, we can avoid these losses. ”

"Is that so?" Li Qingshan thought for a while, nodded solemnly and said, "I can play this package ticket, and there will be no big problems with the welds we weld." If I want to drive, I can stay next to that arm and keep an eye on the solder joints. If you notice that something is wrong, stop the car immediately and there will be absolutely no danger. ”

"If that's the case, that's great. Feng Xiaochen said, "Let's go and talk to Director Li and them together." ”

Li Guoxing, Shang Jinglun and others scratched their heads a little after listening to the plan that Feng Xiaochen and Li Qingshan said.

There is a certain risk in driving without going through a flaw detection test. In case there is a problem with the quality of the weld, and the arm tears again, causing the stator to roll off and crush the flowers and plants on both sides, who will bear this responsibility?

But if it is said that for the sake of safety, everyone will wait here for another day and a night, and the results of the flaw detection may not be any problems, which is too ignorant of the interests of the railway. What's more, the Longshan Electric Machinery Factory also hopes to start as soon as possible, so that the stator can be transported to the Hezhou Power Plant as soon as possible, so as to reduce the time pressure on the follow-up arrangement.

"I don't think we have to wait for the flaw detector. Master Li is experienced, and other welders on the scene also have some experience, so everyone's judgment on welding quality should be more reliable. In addition, we can also do some strain measures and fix the stator with sleepers, so that even if the arm cracks again, as long as it can be stopped in time, it can also ensure that the stator will not roll off the frame. Also, Master Li said that he can escort the car with him, observe the condition of the weld at any time, and stop the train before the weld cracks, so that we basically have no risk. Feng Xiaochen said to everyone.

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

"I support it in principle!"

"I think I can try!"

"Bet on it, 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 another bit and see how determined the ministry is. (To be continued.) )
