Seeing that it was Tang Fei, whether it was the technician Xiao Zhang or the middle-aged welder Lao Liu, they were all shocked, and they were a little excited in their hearts, thinking in their hearts, this is a big boss!

Taking a deep breath, Xiao Zhang tried to calm his mood a little, and then said: "Boss, we have finished welding this part, but it is very strange, the size of the part is all qualified, and the score is exactly the same." ”

Without the slightest error!

This is the main reason why Lao Liu had a hellish expression just now, he has been a welder for so many years, and it is the first time he has encountered such a strange thing.

Generally speaking, such a large-sized part that is tailored together by multiple plates and profiles will have more or less all welding deformations, which will inevitably affect the size of the part.

Lao Liu said with emotion: "This is a part I welded, I am ready to scrap, I didn't expect that the quality will be so good, all sizes are not bad." ”

Knowing what was going on, Tang Fei laughed happily.

The process and technical data produced by the system is one aspect, in addition, it has a BUFF of quality +2, and under this collective halo, the overall quality of the product has virtually gone up a big step.

Welding is carried out in strict accordance with the technical requirements of the process, and the product is qualified, or it is normal to directly reach the level of excellent products!

Tang Fei explained a few words to everyone, and specially instructed that welding should be carried out in strict accordance with the process requirements, and the welding parameters and welding process steps should be exactly the same.

Everyone nodded hurriedly and took Tang Fei's instructions to heart.

In the welding workshop, Tang Fei stayed for almost a whole morning, watched the welding of many parts, and the longest thing he saw was the large-scale welding equipment.

Towards the end of the morning, the large part on this large welding machine was finally welded, and the technicians and quality personnel were already inspecting it.

Undoubtedly, this large part is welded very beautifully, the quality is first-class, whether it is the technicians, or the quality personnel, they feel very satisfied.

In the afternoon, the workers were already preparing for the welding of the first large part, and the cut profiles of various shapes and the profiles with good materials were assembled by the workers and fixed with large tooling, ready to start the welding of the second large part.

Jiuzhou Metro Branch, in the major mechanical processing plants, gradually began to process various parts, and in each plant, the number of workers gradually increased.

Red Star Factory.

Xie Zhenhua is satisfied with the return from the production site, he has to go to the production site almost every day to take a look, mainly focusing on the Shaoshan series, DJ4 electric locomotive production and manufacturing.

The current situation is very good, Jiuzhou Industrial Group's spare parts are endless, constantly sent to the Red Star Factory, there is no need to worry about the shortage of spare parts, the Red Star Factory has to do is to make every effort to organize production, and produce all kinds of electric locomotives.

When I returned to my office, I sat down on the sofa chair in a good mood, and thought to myself, I really want to be grateful to Jiuzhou Industrial Group, without their strong support, there would be no Red Star Factory today.

Well, I haven't seen Tang Fei for a few days, and I don't know what he's busy with, but at this time, is he in the Hexi factory or in the Hedong factory.

Thinking like this in his heart, his secretary knocked on the door and came in, "Leader, in the past few days, I heard that the movement of the Jiuzhou Metro Branch is very big." ”

"Oh. Xie Zhenhua suddenly became interested.

At the beginning, Hongxing Factory also wanted to do subways, but because of upper-level factors, it did not give the subway to Hongxing Factory in the end, but positioned Hongxing Factory as a large-scale electric locomotive manufacturing base in China, specializing in the production and manufacture of various electric locomotives.

Hongxing Factory and subway manufacturing missed each other, but Xie Zhenhua was still very interested in the production and manufacturing of the subway, and after listening to the secretary's report, he immediately asked with great interest: "Tell me quickly, what are the big moves." ”

The secretary said: "The factory area of Jiuzhou Metro Branch has been completed, and a few days ago, they began to process some preliminary processes, and at present, I heard that many parts have begun to enter the welding process. ”

"Oh, it's really not small, it's so quick to get into the welding of parts!"

"Well, I've heard that there are some big parts, and I'm starting to weld them. ”

"Ah, it's progressing so fast. ”

Xie Zhenhua is from a technical background, and he knows that the trial production of the subway, in the initial stage, should be crossing the river by feeling the stones, which is tentative, requiring repeated process verification and design verification, and the whole process is bumpy.

Unexpectedly, the subway trial production of Jiuzhou Industrial Group was so fast, and it actually blossomed in full swing, and some large parts have begun to be welded.

It's unbelievable!

Xie Zhenhua thought in his heart, I must take the time to go over tomorrow to take a look, this is a subway manufacturing, the only one in China, and there is no other branch.

Originally, there were two or three subway manufacturing enterprises in China, but their start was much slower, either in the planning and construction stage of the plant, or in the negotiation stage of technology introduction.

There is no experience in subway manufacturing in China, and there is a lack of related technology, if you want to take a shortcut and manufacture the subway as soon as possible, the best way is to introduce subway manufacturing technology from abroad, and carry out manufacturing on the basis of ready-made technology.

These domestic subway manufacturing enterprises started much slower. The progress of Jiuzhou Metro Branch is relatively fast, not only the construction of the plant has been completed, the installation and commissioning of production equipment has been completed, but also the production and manufacturing have been started, and in a short period of time, the welding of some large parts has begun.

Xie Zhenhua has been engaged in electric locomotives all his life, and he knows that he has entered the welding of large parts, and it is not far from successfully producing and manufacturing the whole train body.

After the car body is manufactured and the paint is sprayed, the final assembly process can be carried out, and it is not far from the successful production and manufacturing of the first subway.

It's unimaginable!

Unbelievable!

If it weren't for knowing that his secretary wouldn't lie, Xie Zhenhua really thought that all this was fake, and since it was true, then he was going to take the time to take a look tomorrow.

……

Jiuzhou Metro Branch.

In each plant, all kinds of spare parts are being manufactured. Tang Fei came to the Hexi base again, and after taking a look at the production site first, Tang Fei entered the huge subway assembly workshop.

This plant is the largest in the entire first phase of the project, with a large area, high standards and large engineering volume. However, it has been fully completed and the installation phase of some assembly stations has begun.

The design of the assembly station is very scientific and reasonable, and the design drawings are also from the technical data of the system. The installation of the assembly station is currently underway.

In the assembly plant, the ground is so clean that it can shine the human figure, and under the guidance of some technicians, some people are working on the process layout in the plant.

On the green epoxy resin floor, various channels and areas are drawn with yellow paint, and various signs are pasted, and the essence of lean production and 6S management is vividly reflected here.

"Brother, are you in the Hexi factory?"

Tang Fei received a call from Xie Zhenhua, "Old Xie, you have also arrived at our Hexi factory." ”

Xie Zhenhua said: "On the way over, I will arrive at the gate of your factory in a few minutes. ”

"Lao Xie, I'm waiting for you at the gate. ”

If it were someone else, Tang Fei would definitely not go to the gate to greet him in person, but Xie Zhenhua is his old friend, and he helped himself a lot in the initial stage of his own business.

Walking out of the assembly plant quickly, along the straight avenue in the factory, a few minutes later, Tang flew to the gate of the factory, and within two minutes, he saw Xie Zhenhua's car.

Seeing Xie Zhenhua get out of the car, Tang Fei said: "Old Xie, your speed is so fast!"

Xie Zhenhua said: "The three bridges of Qingjiang are open to traffic, everything is much more convenient, starting from Hongxing Factory, it didn't take long to cross the bridge directly, and soon arrived in Hexi." ”

This is also the fact that Qingjiang City has developed rapidly in recent years, spanning Hexi and Hedong, not only the previous Qingjiang Bridge, but also the Qingjiang Third Bridge has been opened to traffic, and the fourth and fifth bridges are also under construction.

"Lao Xie, let's go, go to our factory and have a look. ”

This is exactly what Xie Zhenhua wanted, he specially took the time to rush over from the Red Star Factory, not only to go to the factory area of Jiuzhou Metro to have a look, but also to see the production and manufacturing of the first subway.

Under the leadership of Tang Fei, Xie Zhenhua walked into the factory, he had not been here for a long time, and when he came in, he said that the change was really big.

Not only has the greening work done well in the factory area, but the factories are very neat, modern and large, generally exceeding 10,000 square meters.

Walking into one of the factories, Xie Zhenhua saw that there were already a lot of workers working inside, and there were also a lot of parts being machined.

"Brother, you're making so fast!"

Tang Fei said with satisfaction: "Well, the progress is okay, some large parts have been welded." ”

What, already welded!

Xie Zhenhua also thought that some large parts had begun to be welded, but he didn't think that some of the large parts had been welded, and this speed was really amazing.

Xie Zhenhua's interest was even higher, and he took the initiative to say, "Brother, I want to go to your welding workshop to have a look, is it okay?"

Of course.

Tang Fei took Xie Zhenhua, the two talked and laughed, walked out of the machining plant, and walked towards the welding factory. Tang Fei also introduced his current Jiuzhou Metro branch by the way.

After listening to the introduction, Xie Zhenhua expressed regret, if Hongxing Factory and Jiuzhou Industrial Group cooperated to make a subway together, it would be great.

Tang Fei comforted: "Lao Xie, the Red Star Factory's specialized production and manufacturing of electric locomotives is also a good thing, and if you concentrate on one thing, you will definitely be able to make great achievements." ”

In this way, Xie Zhenhua nodded slowly, and he also made up his mind to do the electric locomotive with his heart.

The two walked into the welding workshop.

After coming in, Xie Zhenhua was stunned, not only saw two very large and very advanced welding equipment, but also saw a behemoth on the welding platform of one of the welding equipment!

……

Today's third watch, the third watch is over, thank you!
