Not only Professor Zhao was surprised, but Tong Xia, who was flat on the side, also made slight waves, and looked at Zhuang Jianye with some surprise, not to mention Wu Ping, who had long forgotten what to persuade or not, and asked with some surprise and envy: "Really, Mr. Zhuang, our group also has an electron beam welding machine, which is from Germany and France?"

Zhuang Jianye suddenly had a black line in his head, and said in his heart that your Xiangzhou factory seems to have not been officially merged into Tengfei Group, why did it become us?

Wu Ping also felt that he seemed to be a little too reserved, and just thought about explaining a few words with a smile, he listened to Professor Zhao over there and said: "Xiaozhuang, when I participated in the introduction of technology and equipment for the French 'Dolphin' helicopter, it involved electron beam welding machines.

Because the price in France was too expensive, it was transferred to West Germany, but it was only the introduction of electron beam welding guns and supporting power supplies, and domestic universities and scientific research institutes were responsible for the development of vacuum chambers, and a total of five sets were made, two sets were given to the turboshaft 8 production plant, two sets were given to the Northeast Aviation Development Plant, and the remaining set was taken by the aerospace department, so it wouldn't be this set in your hands, right?"

Electron beam welding machines have a wide range of applications in aerospace, and Tengfei Group is one of the few enterprises that spans the two major business sectors of aerospace.

Especially in the aerospace field, many people in the industry have given high recognition and extreme praise to Tengfei Group, and some people even said unabashedly that if there is no Tengfei Group, the domestic aerospace industry may regress by ten years.

This is in stark contrast to the criticism of the aviation department that Ascendas Group has nothing but a focus on money, which is also an important reason why Ascendas's reputation has become increasingly polarized after the establishment of the Ministry of Aeronautics and Astronautics.

It is precisely because of this that many cadres of the old aviation port even said sourly that the Tengfei Group, which was obviously born in the aviation port, is now like the old aerospace.

As an authority in the aviation industry, Professor Zhao has naturally heard of these things, although with his authority, he can't touch what Tengfei Group provides for the aerospace department, but from the aerospace department's evaluation of Tengfei Group, it is not difficult to see that what Tengfei Group does is absolutely not ordinary.

Based on this, it is understandable that the electron beam welding machine taken by the aerospace department was allocated to Tengfei Group, and a manufacturer that can provide important products to the aerospace department cannot be oversupported.

In any case, the electron beam welding machine also has a great boost to the production of helicopters, which is undoubtedly good news for Professor Zhao.

There is good news, the mood is good, the mood is good, the old man has more words: "En~~ Yes, this is the real family background, I didn't come in vain this time, I can finally see good things, I remember that a few years ago, when Xiao Tong and I participated in the introduction of the 'Dolphin' helicopter, we were busy with the electron beam welding machine for more than three months." ”

"Three months and twelve days. Tong Xia added on the side, her voice was very crisp.

Professor Zhao nodded: "Well, it is indeed long enough, and in the end, I just bought the core spare parts, and made a 2.1-meter-long, 1.3-meter-high, 1.1-meter-wide electron beam welding machine...... Hey, why haven't you seen the GDH-15 electron beam welding machine?"

Talking all the way about the past and the benefits of the electron beam welding machine, the group came to a large factory, just entered Professor Zhao and swept slightly, and did not see the electron beam welding machine he was familiar with.

Zhuang Jianye pointed to a huge equipment about ten meters long and about 4 meters high in front of him, and said in a somewhat modest tone: "Professor, this is the electron beam welding machine used by our group, the model is EJ9, and the GDH-15 electron beam welding machine you said We applied with our superiors, but unfortunately it was not approved to us." ”

"Ah~~ I didn't approve it for you, so you ...... It's a big ...... EJ9？”

At first, Professor Zhao didn't react, he smiled very calmly, and his gray hair was not messy, but the next moment he realized something, raised his eyes to look at the EJ9 electron beam welding machine in front of him, and his old eyes suddenly widened as if they were cracked, and his tone immediately became rhythmic.

I want to say that you didn't get a small one to make a big one, and I felt that it was inappropriate to change my words to EJ9, but around it, my tone was about to twitch, and I was obviously shocked by the electron beam welding machine I saw.

Not only Professor Zhao, Wu Ping and Tong Xia also looked at the electron beam welding machine in front of them in surprise, their eyes were full of incredulity, you must know that the two of them are not people who have never seen the world, following Professor Zhao's authority, they have never seen any good things, but the EJ9 in front of them still shocked them.

GDH-15 electron beam welding machine is really good, the core technology is West German technology, the whole is not bad, can be compared with the length of the vacuum chamber in front of you is 7.5 meters, 2.8 meters wide, 2.5 meters high, the space area is 53.2 square meters, using 45KW and 110KW two electron beam welding guns and EJ9 with automatic welding capabilities.

The 2.1-meter-long, 1.3-meter-high, and 1.1-meter-wide GDH-15 electron beam welding machine can only be regarded as a younger brother, oh no, the younger brother has to add a small word in front of it.

You must know that the GDH-15 electron beam welding machine can already do a lot of things that were unimaginable in the production of engines and aircraft.

At 7.5 meters, 2.8 meters wide, 2.5 meters high, and with a space area of 53.2 square meters, the EJ9 is almost ten times that of the GDH-15 electron beam welding machine.

"The core welding equipment of the EJ9?F-14 central wing box?"

I don't know how long it took, Professor Zhao, who was standing in front of the EJ9 electron beam welding machine, finally came back to his senses and asked, but before anyone could reply, he replied to himself: "Yes, yes, it's EJ9." ”

As he spoke, he turned his head and looked at Zhuang Jianye with shining eyes, pointed to the things being processed inside and asked, "What is being processed here?"

Zhuang Jianye nodded: "It is the central wing box of the advanced light transport aircraft we are developing. ”

"En~~" Professor Zhao nodded, then stood outside the safety line and carefully looked at the processing process inside, and sighed with satisfaction: "The space is really big and the efficiency is really high, it's a pity...... Quantity......"

"Uh...... Professor Zhao, there are four sets of equipment of the same type in our group, and the one you are looking at is only one set, one set is in the Zero degree Factory, and the other two sets are in the Tengfei Aviation Power Plant. ”

Professor Zhao, who was emotional, just wanted to express EJ9 with some regret, although EJ9 is good, the singular number is too little, and he listened to Zhuang Jianye's quick introduction, his old eyes widened uncontrollably again, and he couldn't care about the white hair that was already a little scattered, and suddenly turned his head and changed his voice instantly: "You have ...... in your hands Four sets?"

Zhuang Jianye smiled modestly: "I originally wanted to do ten sets, but you always know that Western countries look at this thing closely, and it is difficult to get it, and in the end only four sets will be obtained, otherwise...... Forehead...... What's wrong with you, Professor? Don't roll your eyes, hey...... Don't scare me, Professor......"
