Regarding the situation introduced by Hu Changzheng, Guo Yonghe did not feel anything strange.

In the eighties and nineties, those foreign high-tech companies always treated Huaxia enterprises with this face, and did not respect Huaxia enterprises as real customers at all.

One of the famous examples is that Huaxia No. 2 Heavy Machinery Group Co., Ltd., located in Bashu Province, imported a set of large equipment from Germany, and after the installation, it was found that there were large cracks in the casting of a frame.

The size of this crack is that after the whole crack is cleaned, it can allow an adult man to lie in a large shape without the slightest crowding.

The leader of Huaxia Erzhong was stunned on the spot. This involves the entire production line, and the responsibility is huge.

The double emergency of burning eyebrows asks for support from a German manufacturer. The German manufacturer delayed for several months, and finally brought a team of experts to Huaxia Erzhong for repair.

The repair plan they proposed did not say that we would rebuild the frame for you, but used surfacing welding, and used argon arc welding to flatten this big crack.

The German expert group welded for three months, used up 20 tons of welding rods, and finally the crack was flattened.

Then the German manufacturer also sent a professional team to carry out flaw detection and testing on the flattened crack with ultra-detection and other instruments, and finally issued a report, requiring Huaxia Erzhong to use the entire set of equipment restrictively, and only use 70% of the original design capacity at most. Otherwise, all the consequences will be borne by Huaxia Erzhong itself!

Now Texas Instruments and Siemens' treatment of Zhongtian Aluminum Plant is just a repetition of the double story of China.

What made Guo Yonghe feel a little embarrassed was that Zhongtian Aluminum Factory proposed to repair it within three days.

If in the previous life, when he was the chief technician of the new energy vehicle giant, if it was said that there was a printed circuit board of an industrial computer that needed to be repaired within three days, it was really not difficult to say to him.

Because he himself is a top master in the maintenance of printed circuit boards, and even a member of the Precision Welding Branch of the International Welding Association, he not only has superb precision welding technology, but also has set up a personal precision welding laboratory to undertake some difficult printed circuit plug-in board maintenance business.

But now, let Guo Yonghe pat his chest and promise to repair a printed circuit board within three days, he really didn't dare to pack a ticket.

Repairs to printed circuit boards rely primarily on precision soldering technology.

Precision welding is actually a marginal science, no matter how advanced the theory in this field is, it is useless, and it mainly relies on a lot of practice to accumulate experience.

For Guo Yonghe, in his last life, his personal precision welding laboratory repaired tens of thousands of printed circuit boards, creating economic benefits of hundreds of millions, and his practical experience is also at the top level in the whole country, otherwise he would not have been selected as a member of the Precision Welding Branch of the International Welding Association.

But the problem is that no matter how rich the practical experience is, it also needs to be supported by professional equipment and instruments.

In the previous life, the precision welding laboratory he opened had all kinds of advanced instruments and equipment, but now, he is poor, and he doesn't even have the simplest electric soldering iron.

Although he can make some self-made equipment to replace the advanced equipment and instruments in his precision welding laboratory in the previous life, but doesn't it also take time?

If the failure of the printed circuit board of the industrial computer of Zhongtian Aluminum Factory is not serious, he only needs to make some simple equipment to complete the repair, then three days is enough for him.

If the printed circuit board of the industrial computer of Zhongtian Aluminum Plant is very seriously faulty, such as the partial burning of the printed circuit and the loss of insulation, carbonization in the full thickness, or the integrated block on the printed circuit board is burned, and the separation capacitor element is burned "flying" and other serious faults, then it involves cutting off the carbonized part of the substrate, inlaying the new dihydroepoxy resin board to replace the damaged substrate, installing a new integrated block, and may also involve the soft brazing between the separating capacitor components and the integrated block, etc.

The problem is that the integrated blocks and components on the printed circuit board are burned, but the procurement of these things is not under Guo Yonghe's control, in this case, let alone three days, that is, three weeks, Guo Yonghe does not dare to pack tickets.

"Section Chief Hu,"

Guo Yonghe naturally didn't dare to talk nonsense on this issue, "There are many faults in the printed circuit board of the industrial computer, and it is definitely not difficult to repair a small problem within three days, and if a major problem is encountered, the time limit is not easy to say."

"So I can't promise you anything now, I can only go to the scene and see the actual situation."

What Hu Changzheng said about the way of nature and Guo Yonghe is the truth.

In fact, he ran over to ask Guo Yonghe, and he didn't expect Guo Yonghe to be able to repair it within three days. Mainly with the idea of playing three poles with dates and without dates, if Guo Yonghe can repair it within three days, he will naturally make a lot of money, and his son will definitely be left by Zhongtian Aluminum Factory.

Even if Guo Yonghe can't fix it, his son Hu Dongqiang will not suffer any loss, at least to show the leaders of Zhongtian Aluminum Factory an attitude of actively participating in the affairs of the factory!

"It's okay! Technician Guo, whether it can be repaired within three days or not, I will remember your friendship! ”

Hu Changzheng said: "In the future, as long as there is anything useful to me, you just have to come to me, if I say one more word, you can just slap me!" ”

Listening to Hu Changzheng's rough words, Guo Yonghe couldn't help but laugh dumbly.

If you hadn't heard it with your own ears, who would have thought that these words would come from the mouth of the head of the equipment section of a large provincial factory?

Soon, they came to the Zhongtian Aluminum Factory.

Hu Dongqiang was standing at the gate of Zhongtian Aluminum Factory, waiting anxiously, when he saw the jeep of the Heavy Machinery Factory driving over, he immediately hurried to meet him.

"Dongqiang,"

Hu Changzheng pointed at Guo Yonghe and introduced: "This is Guo Technician from the internal distribution factory, he made a special leave to help you repair the printed circuit board, don't hurry up and thank him!" ”

"Thank you, Technician Guo!"

Hu Dongqiang looked at Guo Yonghe, who was about the same age as himself, although he was full of suspicion, but he obediently thanked Guo Yonghe according to Hu Changzheng's words.

No way, who made him want to stay in Zhongtian Aluminum Factory?

Regardless of whether this young technician Guo is reliable or not, it always doesn't hurt to give it a try.

"Hehe, it's all your own people, what's polite!"

Guo Yonghe waved his hand to Hu Dongqiang, "Let's go, take us to the scene to see what's going on!" ”

So Hu Dongqiang said hello to the doorman, then jumped into the jeep, took them into the factory, came to the equipment on the first floor of the factory office building, and knocked on the door of Li Weijin, the director of the office of the equipment department.

"Director Li,"

Hu Dongqiang reported respectfully: "My father invited Guo expert, who repaired the printed circuit board. ”

Li Weijin is a white and fat middle-aged man, who looks like Maitreya Buddha.

He couldn't help but be stunned when he saw Guo Yonghe standing next to Hu Changzheng.

Although Hu Dongqiang had already reported to him that Expert Guo was very young, he really didn't expect Guo Yonghe to be so young, and he looked as if he was the same size as Hu Dongqiang, who had not yet walked out of school.

"Expert Guo, hello, I really didn't expect you to be so young!"

Fortunately, he quickly came back to his senses, stretched out his fat hand, and greeted Guo Yonghe with a smile.

"Director Li, how are you! ”

Guo Yonghe shook hands with Li Weijin and replied with a smile: "I just look young, I am actually born in sixty-nine years, and I will be twenty-three years old soon!" ”

Li Weijin was almost choked by Guo Yonghe's words.

Even Nima is less than twenty-three years old, dare to say that she looks young?

Is this generation of young people so difficult to bring?

He stood firm and stretched out his hand to Hu Changzheng again, "Section Chief Hu, I'm bothering you!" ”

"Hey, Director Li, you're so polite!"

Hu Changzheng shook his head again and again and said, "I have known Expert Guo for a long time, and inviting him over is just a gesture. It's Dongqiang who works under you, and a lot of them make you worry about it! ”

After a few simple greetings, Li Weijin talked about the topic.

"Expert Guo, the situation is like this......"

Compared with the situation introduced by Hu Changzheng to Guo Yonghe in the car, Li Weijin's introduction has more content.

Originally, the main product of Zhongtian Aluminum Plant was alumina, and the last process in alumina production was the roasting of aluminum hydroxide. When the process of Zhongtian Aluminum Plant was put into operation, it adopted the internationally advanced flash roaster, and the industrial computer used in it was designed by Humboldt Vidack Company in Germany and produced by Honeywell Company.

A year ago, Zhongtian Aluminum Plant was ready to put into the construction of the second phase of the project, and at this time, the model of the flash roaster industrial computer equipment used in the first phase of the project was included in the list of obsolete equipment by Honeywell, and no equipment maintenance services were provided.

Therefore, Zhongtian Aluminum Plant decided to switch to Texas Instruments' industrial computer on the flash roaster production line of the first phase of the project, so as to prepare for the second phase of the project to be completely free of Texas Instruments' industrial computer.

Unexpectedly, Texas Instruments finally sold the industrial control department to Siemens in Germany, and Zhongtian Aluminum Plant jumped from one big pit to another!

"Director Li, I almost understand the situation!"

Guo Yonghe nodded and said: "I still ask Director Li to take me to the scene, I want to take a look at the damage to the printed circuit board in person, so that I can specifically judge whether it can be repaired and how long it will take." ”

"Okay, okay!"

Li Weijin nodded, led the way in front, and prepared to take Guo Yong and them to the equipment maintenance department.

As soon as he walked into the corridor, he was confronted by several people, led by a middle-aged man wearing a Pierre Cardin long trench coat, and his momentum was extremely extraordinary.

The middle-aged man caught a glimpse of Li Weijin and Hu Changzheng's father and son and Guo Yonghe behind him, and couldn't help but stop and asked Li Weijin: "Old Li, what are you going to do?" ”

"Director Zhang,"

Li Weijin hurriedly laughed and said: "Isn't the printed circuit board of the industrial computer of the flash roaster production line broken?" Xiaohu's father, a college student who was interning at our office, happened to know an expert who could repair printed circuit boards, so I asked him to invite this expert over to see if he could help us repair the printed circuit boards......
