Xie Zhenhua and other senior executives of the Red Star Plant were almost all present, and watched with joy as the electric locomotive slowly drove out of the delivery workshop.

In addition to almost all the top management of the Red Star Factory, there are many other people, such as production workers, technicians, management personnel and so on.

In addition, there are some people in the acceptance room, who are also happy. After several months of stoppage, the DJ4 has finally resumed production, and now a DJ4 electric locomotive is finally ready for delivery.

"Mr. Xie, thank you, thank you so much!"

Watching this brand-new DJ4 slowly drive out, the director of the acceptance room, with a grateful face, held Xie Zhenhua's hand tightly.

Xie Zhenhua said: "It's so polite, this is what we should do, if you really want to thank you, I think the most should be thanked is Jiuzhou Industrial Group." ”

"Yes, I will definitely visit several leaders of Jiuzhou Industrial Group, including Mr. Tang. The director said.

In the midst of everyone's happy eyes, cheers, and even warm applause, this DJ4 drove out of the delivery workshop. If you look into the factory building of the delivery workshop, you can see that there are two or three DJ4 electric locomotives inside, which are expected to be delivered in the next few days.

"Mr. Xie, the celebration banquet in the evening has been arranged, and all the relevant people in our factory have been notified in place, what do the people outside need to be notified?"

Xie Zhenhua said: "You can make your own decisions about who to invite, but one thing must be remembered, Mr. Tang of Jiuzhou Industrial Group must be invited, without their spare parts, it is impossible to have the delivery of our DJ4." ”

Since Jiuzhou Industry fully resumed the supply of spare parts for various electric locomotives of Hongxing Factory, all kinds of spare parts have been sent to Hongxing Factory one after another.

Hongxing Factory no longer has to worry about the lack of spare parts, whether it is Shaoshan electric locomotive or DJ4 electric locomotive, all of them have got rid of the predicament and embarked on the fast track of production.

Xie Zhenhua even carefully planned that with such a good production situation, at least 10 DJ4 electric locomotives would be produced every month.

Today's delivery is the first one since Xie Zhenhua took office, and the follow-up will be delivered one after another, one after another, about 10 units per month, which is not a big problem.

The first DJ4 was successfully delivered, which was completely exciting news for the Red Star Factory, and many employees were happy and hotly discussed.

"Mr. Xie has only been in office for a long time, and the first DJ4 has been successfully delivered. ”

"I've heard that in two days, another one will be delivered. ”

“……”

The people of the Red Star Factory are discussing this matter, everyone knows that this is just a good beginning, from now on, DJ4 will be delivered one after another, and the Red Star Factory has finally been completely reborn, completely getting rid of the predicament of the Taiwan Security Army era.

……

Jiuzhou Metro Branch.

Soon after the successful delivery of the first DJ4 of the year, the welding workshop finally started and the welding of some large parts began.

In the factory, one of the large welding equipment is already making a series of preparations, several workers are busy, and several technicians are guiding by the side.

On the huge welding platform, a number of large parts waiting to be welded have been hoisted, with a visual length of more than 20 meters, and welding will begin shortly.

Tang Feilai, accompanied by Ma Jianwei and others, personally went to the production site of the welding workshop, saw the large parts ready to be welded, and also saw the workers and technicians who were doing the pre-welding preparations.

Ma Jianwei said: "Boss, the preparation will be done soon, and welding will be carried out soon." ”

Tang Fei said: "Well, wait a minute, let's see with our own eyes, let's weld the situation." ”

This is a large welding equipment that can be exchanged in the system, with a high degree of automation, and multiple welding robots can move along long guide rails and can weld multiple welds at the same time.

Tang Fei wanted to see what the welding equipment produced by the system would be.

Under the guidance of technical personnel, the workers are operating step by step in accordance with the requirements of process technical data, mainly some preparations before welding.

If the workpiece that needs to be welded is clamped, the position meets the process requirements. The large tooling for clamping is very scientific, reasonable in design and easy to operate.

For such a large welding tooling, the design drawings are also from the system. In the detailed process and technical data produced by the system, a variety of process equipment is involved, and all of these tooling have detailed design drawings and operation instructions.

Many tooling has been manufactured to be used for the welding of parts, such as this large welding tooling, and with it, everything seems to be simpler.

Soon after, the preparations were ready.

Ma Jianwei said: "Boss, do you want to start welding now?"

Tang Fei waved his hand and said, "Let's start now, let's take a look at the welding situation." ”

With Tang Fei's consent, the technicians began to instruct the workers in the operation of the welding equipment, and it didn't take long for the equipment to start working.

The welding manipulator clamps the aluminum alloy electrode and starts the welding of the weld under the protection of argon. Multiple robots are working at the same time and welding at the same time.

Arc Splash!

The scene is very spectacular and very gratifying.

This kind of welding efficiency is very high, Tang Fei roughly estimated that such welding efficiency is not comparable to even ten skilled welding workers.

The weld is gradually taking shape and the length is getting longer and longer. Under the control of the numerical control program, the manipulator will change the angle from time to time in order to adapt to different welding positions.

"Boss, such a welding scene looks really gratifying!"

Tang Fei said: "Yes, in a few days, the other large-scale welding equipment will also be put into use, and the scene will be even more spectacular." ”

Gradually, many welds are welded into shape.

Tang Fei took the lead and walked over, getting closer, and could clearly see a welded weld. Someone shouted loudly with joy.

"Look, how beautiful the weld is, a typical fish scale weld, such a weld, so beautiful!"

"Yes, it's exquisite, at least at the level of a welding technician. ”

Everyone was extremely happy to see such a beautiful and delicate weld. Tang Fei also nodded with satisfaction, such a high-quality weld was a little beyond Tang Fei's expectations.

In addition to the advanced welding equipment, the welding process parameters of welding can be welded with this quality.

The welding process data produced by the system has detailed welding parameters, such as welding current, temperature and humidity requirements, welding speed and so on.

It is not surprising that such a high-quality weld is welded in strict accordance with these process parameters. Knowing this, Tang Fei thought happily in his heart, this time he really made a lot of money.

These technical data are all from the system, including design technical data, process technical data, etc. Using the R&D function of the system, spend some gold coins, and you have these technical data, although the normal R&D mode costs twice as many gold coins as the simple R&D mode, but the information is more detailed, and these gold coins are fully worth.

This is a large part, twenty or thirty meters long, the kind of long, short welds are enough to have hundreds, the workload of welding is huge, if it is manual welding, it is estimated that there will not be several days, and the welding will not be completed.

And on this large-scale welding equipment, several manipulators are welding at the same time, under the control of the numerical control program, the arc shines, the speed is fast, it is estimated that it takes about half a day, and the welding can definitely be completed.

Such a welding scene looked pleasing to the eye and was in a happy mood, Tang Fei was a little reluctant to leave, and watched there for more than an hour, and saw that the welding volume was completed by more than one-third, and then left.

In the entire welding workshop, Tang Fei went to other welding stations to take a look, and there were some small and medium-sized parts, which were manually welded.

No, there are some people next to a welding platform.

There were two welders, and there was also a young technician, looking like this, who was preparing to start welding a part.

Among them, the older welder, who looks to be in his forties, belongs to the experienced old workers, he leads, and the two young welders next to him are working on the preparation before welding.

The middle-aged worker said: "Xiao Zhang, you don't need to verify the process, can you just start welding directly?"

Technician Xiao Zhang said: "No need for process verification, you can check whether the welding parameters are correct, in addition, in strict accordance with the welding steps on the process technical data, there can be no deviation." ”

The middle-aged worker nodded.

This kind of situation, apparently he is the first to have a bad encounter. He used to work in a state-owned enterprise and has been engaged in welding, and in his career, he knows that the welding of new parts generally requires process verification, such as verifying the size of the welding current, the appropriateness of the groove size, and the sequence of welding.

Here, it's a bit strange that the official parts are welded directly without verification.

But the technician Xiao Zhang said so, and he did it, but he put a big question mark in his heart, and he was also a little worried, so the quality of the welded parts is estimated to be not very good.

With such worries in their hearts, middle-aged workers do not dare to be careless and weld in strict accordance with the requirements of the welding process.

The weld is formed little by little, and the first weld is welded.

The young worker next to him said with admiration: "Lao Liu, you are worthy of being a master, you really have a hand, how delicate and beautiful this weld is." ”

The middle-aged worker, that is, Lao Liu, he was also slightly surprised, he welded in strict accordance with the process parameters, and the quality of the welded weld was so good, he knew in his heart that the weld could achieve such a quality, and his technical level had a certain relationship, but it was not an absolute relationship.

"Lao Liu, that's good. The technician next to him also praised.

The quality of the first weld is good, Lao Liu is relieved a lot, throws off his arms, and carefully welds all the remaining welds, and this part is considered to be welded.

Put down the welding gun, loosen the welding work, so that the parts are no longer in a clamping state, but reach a free state, Lao Liu began to measure and detect the size of the parts.

After taking some measurements, Lao Liu had a ghostly expression.

"What's the matter, Master Liu. Xiao Zhang, the technician next to him, asked.

Lao Liu said: "What the hell, you come and measure." ”

Picking up the measuring tool and measuring several major sizes, Xiao Zhang was also surprised and said "huh" gently.

Coincidentally, Tang Fei came here accompanied by Ma Jianwei, and originally wanted to take a look at the welding of these parts, but when he saw them like this, he couldn't help but ask with concern.

"What's wrong, what's wrong?"

……

Today's three watches, the second one is sent!
