The next morning, the leaders of Guilu also held a warm welcome ceremony, in the small hall of the factory, and then moved to the conference room and held a small meeting.
At the meeting, the performance of aluminum alloy materials was mentioned again, and Qin Dong once again raised it.
The chief engineer of Guilu is named Guan Renjie, who is also an old material expert, as soon as he heard what Qin Dong said, he couldn't help but stand up and say loudly: "Qin Gong, of course we are very aware of the importance and urgency of this model, but any scientific research project must follow the law, of course we will do our best to ensure that the design index requirements are met in the shortest possible time, but we have to give us a little time, right?"
” Qin Dong smiled and said, "We can wait, but the navy may not be able to afford to wait."
Chief Engineer Guan, it is clear that you will only be given half a year to solve the problem of aluminum alloy materials for the new missile boat, even if our design unit can help you fight for it, is that one year enough?
” Chief Engineer Guan also seemed to have a temper tantrum, and when he saw Qin Dong say this, he couldn't help but slap his palm on the table anymore, knocking down the teacup in front of him.
Wang Hongsheng, the director of Guilu, hurriedly persuaded: "Lao Guan, what are you anxious about?
Something to say!
” Wang Hongsheng knows very well that Chief Engineer Guan is very skilled and is a few experts in China, and Qin Dong is also a material expert, and the two are about the same age, so it is estimated that these two people are on the bar.
If it really started a quarrel at this first meeting, then if the above heard about it, I was afraid that they would be held accountable.
After all, the chief division unit is equivalent to the commander-in-chief of the model, and these subcontractors must be treated as if they were guests.
How do you know that Guan Renjie didn't buy it and said: "Lao Wang, don't care!"
Isn't it half a year?
I, Guan Renjie, have made a military order here today, and if we fail to develop aluminum alloy materials that meet the requirements of the design indicators of the new missile boat within three months, I will voluntarily take the blame and resign and leave this industry from now on!
If we complete the task in three months, then what can we say?
Can you 701 hand over all the marine aluminum alloys to us?
” Qin Dong smiled and said: "I can't promise you this, I don't have that power, I'm just a little designer, but I can suggest to the leaders of the institute, whether I can agree or not is the leader's business!"
” Of course, Qin Dong couldn't agree, because he really didn't have the power.
Of course, he didn't want to gamble with the other party, so he just took the opportunity to vent the emotions gathered in his heart.
He was deflated by Shen Huan, and now he feels that it is impossible to eat deflated in this precious aluminum.
Before Guan Renjie could say anything, Wang Hongsheng, the factory director on the side, hurriedly dragged him back to the chair and gave him another look.
Only then did Wang Hongsheng turn his head to Yang Xiaoyi and Qin Dong and said, "That, Chief Master Yang, I'm really embarrassed, Lao Guan has this temper, and the comrades in our factory know it."
Don't be angry with him, I'm here to apologize to you on his behalf, and let's get down to business, ah!
” Yang Xiaoyi hurriedly said: "Director Wang, don't say that, our Qin Gong is also at fault in this matter, okay, don't always worry about this matter, let's go back to the topic."
The importance and urgency of this model must be well known to everyone, and the above requires us to complete the design and development within three years, and complete the delivery task.
Three years is not a long time, and it is not a short time, but it is indeed a bit short for a model of weapons and equipment.
Generally speaking, it takes more than 10 years to design and develop a large and medium-sized warship, and it takes more than five years to develop a small warship. ” Everyone here couldn't help but get nervous, this development cycle is indeed a bit short.
"That's not to mention, our model uses more than 70% of the new technology, so you can imagine how difficult it is.
If our supporting units can complete the research and development tasks ahead of schedule, then our overall progress will be accelerated a lot.
Of course, I still think that speed is important, and quality is even more important.
The special structural materials for ships have the characteristics of long development cycle and high technical content, although we are small boats, but we cannot ignore them.
Take our submarine high-strength steel as an example, it took 30 years from the project to the successful development, of course, our aluminum alloy materials are improved on the basis of the existing ones, but the difficulty can also be imagined, here I want to represent our design institute, thank you for your strong support to us!
Thank you!"
Wang Hongsheng, the director of the factory, hurriedly stood up and said: "Chief Master Yang, don't be like this, we are all for the model, for the country, I assure you that we will definitely come up with products that meet the design requirements in the shortest possible time, please rest assured!"
” Yang Xiaoyi said happily: "Then thank you so much Director Wang."
However, we will strengthen communication in the future, especially in the welding process, and I hope that we will also cooperate with the comrades in the shipyard to do a good job in this regard. ” Wang Hongsheng looked at Shen Huan and said: "Shen Gong, in the future, we will strengthen cooperation between the two sides, the welding of aluminum alloy materials is indeed quite difficult, I hope we can solve this problem together!"
” Shen Huan smiled and said, "Director Wang, it's no problem."
In fact, the welding process of aluminum alloy hull is not so difficult, I have seen our precious aluminum product information, and we have also used your aluminum alloy products before.
The difficulty of welding aluminum alloy materials lies in the fact that the linear expansion coefficient is large, the thermal conductivity is strong, and it is easy to warp and wave deformation during welding, so it is more difficult to build an aluminum alloy hull than a steel hull.
Our new missile boat will be built with an all-welded structure, and we are working on a pulsating production line, if this kind of production line is built, it will solve many process problems, such as precision control, deformation control, etc.
Realize the rapid mass construction of new missile boats. ” Guan Renjie laughed on the side: "Little comrade, do you really have confidence?
Can you represent you Jiangnan Changxing Shipbuilding Group?
” Since Guan Renjie is not an expert in the shipbuilding system, he still doesn't know that Shen Huan is already the youngest expert in the shipbuilding system, he thinks that the shipyard has sent a craftsman at random!
Because Shen Huan is indeed too young, much smaller than Yang Xiaoyi.
Shen Huan said without humility or arrogance: "Chief Engineer Guan, of course I can represent our company."

Our company has long studied aluminum alloy welding technology, such as tungsten TIG welding and molten JGG welding.
Of course, now we are also studying plasma welding, friction stir welding and other processes, and it seems that the application of MIGG welding and friction stir welding is more promising.
If our pulsating production line is successful at that time, we can apply a large number of welding processes based on automatic welding and assisted by manual welding to achieve a high degree of automation and pulsating production. ”
