Not only Professor Zhao was surprised, but Tong Xia, who had a dull face on the side, was also slightly confused. She looked at Zhuang Jianye with some surprise. As for Wu Ping, let alone Wu Ping, who had already forgotten what to advise or not, asked with some surprise and envy. : "Really? Mr. Zhuang, our group also has an electron beam welding machine? Is it from Germany or France?"
Zhuang Jianye suddenly felt a black line on his forehead and thought to himself: It seems that your Xiangzhou factory has not been officially merged into the Ascendas Group. How come it has become us?
Wu Ping also felt that he was a little too unreserved. He smiled and was about to explain a few words to smooth things over when he heard Professor Zhao over there say: "Xiao Zhuang, I was involved in the technology and equipment of the French 'Dolphin' helicopter." When introduced, electron beam welding machines were involved.
Because the price charged by France was too expensive, it was later transferred to West Germany. However, it only introduced electron beam welding guns and supporting power supplies. Domestic universities and scientific research institutes were responsible for the development of vacuum chambers. A total of five sets were made, and two sets were given to the turbine shaft. 8 production plant, two sets were given to the Northeast Aviation Development Factory, and the remaining set was reportedly taken away by the aerospace department. Could it be that this set fell into your hands? "
Electron beam welding machines are widely used in aerospace, and Ascendas Group is one of the few companies that spans the two major business segments of aerospace.
Especially in the field of aerospace, many people in the industry have highly recognized and praised Ascendas Group. Some people even bluntly said that without Ascendas Group, the domestic aerospace industry may be set back ten years.
This is in sharp contrast to the criticism from the aviation department that Ascendas Group is only focused on money and has no regard for anything else. This is also an important reason why Ascendas Group¡¯s reputation has become increasingly polarized after the establishment of the Ministry of Aeronautics and Astronautics.
Because of this, many cadres from the old aviation industry even said sourly that the Ascendas Group, which was clearly born in the aviation industry, now behaves like an old aerospace company.
As an authority in the aviation industry, Professor Zhao has naturally heard of these things. Although he cannot touch what Ascendas Group provides to the aerospace department due to his authority, it is not difficult to see from the aerospace department's evaluation of Ascendas Group. What Ascendas Group does is definitely extraordinary.
Based on this, it is understandable that the electron beam welding machine taken away by the aerospace department is allocated to Ascendas Group. A manufacturer that can provide important products to the aerospace department cannot be supported too much.
And this also put a bit of a full smile on Professor Zhao's calm face. In any case, the electron beam welding machine also greatly assists the production of helicopters, which is undoubtedly good news for Professor Zhao.
If you have good news, you will be in a good mood. When you are in a good mood, the old man will talk more: "Well~~ Yes, this is the real family wealth. I didn't come here in vain this time. I can finally see good things. Remember A few years ago, when Xiao Tong and I were involved in the introduction of the Dolphin helicopter, we worked on the electron beam welding machine for more than three months."
"Three months and twelve days." Tong Xia added in a crisp voice.
Professor Zhao nodded: "Well, it's indeed long enough. In the end, I just bought the core spare parts and built an electron beam welding machine that is 2.1 meters long, 1.3 meters high, and 1.1 meters wide. The technology in this field was integrated into the machine at once." It is a big step closer to the world's advanced level and fills the gap in the country. I think the aerospace department is also interested in this, so they bought one Hey, why haven't I seen the gdh-15 electron beam welding machine?"
Talking about the past events and the benefits of electron beam welding machines, the group came to a large factory. When they entered, Professor Zhao took a quick look and did not see the electron beam welding machine he was familiar with.
Zhuang Jianye pointed to a huge piece of equipment in front of him that was about ten meters long and about four meters high. He said in a somewhat modest tone: "Professor, this is the electron beam welding machine used by our group. The model is ej9. What did you say?" We applied to our superiors for the GDH-15 electron beam welding machine, but unfortunately it was not approved for us."
"Ah~~ If it is not approved for you, then you will make a big ej9?"
At first, Professor Zhao didn't react. He nodded and smiled very calmly, with his gray hair intact. But the next moment, he realized something. He raised his eyes and looked at the ej9 electron beam welding machine in front of him. His squinted old eyes looked like they were cracked. His eyes widened suddenly, and his tone immediately changed his rhythm.
I wanted to make a big one if you didn¡¯t get the small one, but I thought it was inappropriate and changed my words to ej9. However, my tone was almost twitchy. 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 disbelief. You must know that they are not people who have never seen the world. Following Professor Zhao, this authority, they have never seen anything good. , but the ej9 in front of them still shocked them.
The gdh-15 electron beam welding machine is indeed good. The core technology uses West German technology and is not bad overall.It can be compared with the ej9, which is 7.5 meters long, 2.8 meters wide, 2.5 meters high, and has a space area of ??53.2 square meters. It uses two electron beam welding guns, 45kw and 110kw, and has 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, a small word has to be added in front of the younger brother.
You must know that the gdh-15 electron beam welding machine can already do many things in engine and aircraft production that were previously unimaginable.
7.5 meters, 2.8 meters wide, 2.5 meters high, with a space area of ??53.2 square meters, the ej9 is almost ten times that of the gdh-15 electron beam welding machine, and the things it can do are naturally even more unimaginable.
"ej9? The core welding equipment of the f-14 central wing box?"
I don¡¯t know how long it took, but Professor Zhao, who was standing in front of the ej9 electron beam welding machine, finally came to his senses and asked, but before anyone could reply, he replied to himself: ¡°Yes, yes, yes, It¡¯s ej9.¡±
As he spoke, he turned his head and looked at Zhuang Jianye with bright eyes, pointed at 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."
"Yeah~~" Professor Zhao nodded, then stood outside the safety line and carefully watched the processing process inside, sighing with satisfaction: "The space is so big, the efficiency is so high, but it's a pitythe quantity"
"Um Professor Zhao, our group has four sets of the same type of equipment. What you see in front of you is just one of them. There is another set at the Zero Degree Factory and the other two sets at the Tengfei Aviation Power Plant."
Professor Zhao, who was feeling emotional, was just about to express some regrets that although ej9 is good, there are too few odd numbers. When Zhuang Jianye quickly introduced it, his old eyes widened uncontrollably again, ignoring his already scattered white hair. He suddenly turned around and his voice suddenly changed in tone: "You havefour sets on hand?"
Zhuang Jianye smiled modestly: "Originally I wanted to get ten sets, but as you know well, Western countries take this thing seriously and it is difficult to get it. In the end, I only got four sets, otherwise um Professor, you What's wrong? Don't roll your eyes, hey Professor, don't scare me"
