A nation's industrial development begins with junior engineers.

As mentioned earlier, the railway system is like an independent kingdom.

If outsiders want to get anything done for them, it's extremely difficult. Let alone getting a few precious enclosed carriages for any kind of modification.

But Jiang Xia is different; he has the Ministry of Railways badge.

Within minutes, Wang Dadan received the news and immediately called.

"Hahaha! Comrade Xiao Jiang, I heard you have another great idea?"

"Yes, Uncle Wang, how about learning about mobile cold storage?"

"Xisuo!"

"Simply put, it's like installing a giant refrigerator inside the train carriage..."

After some explanation, Wang Dadan quickly made his decision: "I'll arrange for a few carriages to go there tomorrow! You can have someone over there receive them..."

"Huh? Don't you need to discuss this in the meeting?"

"Tsk, you underestimate your Uncle Wang, don't you? You're still discussing this? By the way, how are you spending the New Year? Want to come over for a nice meal? Uncle Wang is going to speak at the meeting! Come and listen!"

"Oh! Okay! But Uncle Wang, your speech might need some revisions in a few days!"

After a moment's thought, Wang Dadan recalled some unknown events surrounding this young man, and his eyes lit up: "Great! Uncle is waiting for your good news! I'll write this speech myself!"

"How about I send the wagons over today?"

"Ming, I've got some processing equipment ready. Could you please take it to the people in Zhuzhou for me?"

As Jiang Xia spoke, he took out the assembly diagram for friction welding and gestured to Lao Wang to deliver it to the confidential workshop.

Ironically, the first patent application for friction welding was actually filed by an engineer from Big Brother in 1956. Unfortunately, it was the United States, across the ocean, that further promoted it. Later, the United States transferred the technology, and Japan thoroughly understood the technology, then dumped related equipment on its American patron.

At the same time, relying on this technology, they also managed to gain a significant foothold in my country's white goods industry in later generations.

But now.

Is a friction drive system difficult? Isn't it just a flywheel that stores energy and then releases it during welding?

Flywheels, let alone small cannons, look at all those punch presses lined up in the workshop, every single one of them has a flywheel spinning like crazy.

And there's the upsetting system, hey, isn't it just about applying axial pressure?

The hydraulic components on a 1000-ton free forging machine will tell you, we can do it!

As for the cooling system, don't forget the five-bladed mini fan on the air fryer. That's something you could enlarge and use on a large blackfish...

Little fan, beep beep, I won't stop until I catch you a cold!

However, the control unit is a bit lacking, but that's okay. We can just treat it as a dedicated welding device for copper and aluminum parts. Once Dr. Lan Ying's integrated circuit comes out, we can replace it!

To say that Hongxing Steel Rolling Mill could produce this friction weld in one night is an underestimation of their capabilities.

Once machining reaches a certain scale, it will only become more and more advanced.

……

In a certain place in Beijing, several high-ranking leaders were looking at the report that Comrade Jin Guang had just submitted.

"We had no guns, no cannons, the enemy made them for us!"

The bearded man waved his arms and directed the group to sing, which made everyone laugh for a while.

"Excellent! This shows that our comrades, whether in local areas or in the navy, are doing their work quite thoroughly!"

The first guardian flicked his cigarette ash, a satisfied smile returning to his previously weary face.

"Sir, do you think we should publicize this matter? Wouldn't publicizing it be too provocative to the other side?"

"Heh, exciting? I'd love to! Ideally, they'd all come out in force! We could finish them off in one fell swoop! Mosquitoes, fleas, and the like—we'd swat them all dead!"

"Hahaha! Commander, I think you've overestimated them. If they had that kind of courage, I'd think highly of them! With their retreat skills, I bet they're just playing the victim with the bald eagles again, begging them to sell them some more weapons!"

"Ha ha ha ha……"

"That's perfect! Let's give this sea snail another go! Hey, maybe Comrade Jin Guang will jump for joy again!"

“Isn’t that perfect? ​​If they buy it, it’s like we have it too!” Another old man clapped his hands and laughed.

The First Guardian waved his hand, a wisp of ash sliding down: "This matter absolutely needs to be publicized! Let the enemy know that we are not to be trifled with! Just like ten years ago!"

"Furthermore, we should combine propaganda with the story of the firecrackers. One firecracker and one sea snail will let the enemy know that we are becoming increasingly formidable!"

All attendees nodded in agreement.

only……

"Sir, should we change this name? Maybe something like 'Changying'?"

"Hahaha, it's good to make changes! By the way, let me see who invented this sea snail. It seems to be one of our researchers who copied it from the Alliance, right?"

"It's not really a copy anymore, because the relevant comrades have made a lot of improvements on the original. It can be said that the performance of the Hailiuzi has surpassed the original in every aspect. Not to mention anything else, the range has increased by a lot!"

As the attendees introduced themselves, the First Guardian nodded slowly and said, "How about we call it..."

Ok?

Why does this name on the R&D list look so familiar?

Oh, this little brat. Well, of course, no one else would have such an unreliable name.

However, this is still better than that series of "based on".

"Well, after hearing this name for a while, it actually sounds quite down-to-earth, like our old 'homemade guns' or 'homemade cannons'! Let's just consider it a reward for him!"

The old man smiled and decisively settled the matter.

However, the old man's next action surprised everyone.

"Come on, show my humble work to the little guy, so he can find inspiration from it when he's naming his child next time he's feeling accomplished. Our good young man should still have some of these qualities..."

"Hmm...it needs to have some romantic elements!"

The old man thought for a moment and then changed his wording.

There's no way around it; the researchers' rigid attitude has become deeply ingrained, and even the elderly don't know how to comment on it, ultimately ending with "romantic."

The little one is an exception, except his literary skills are a bit lacking...

However, no matter how many times he changed it, the staff who received that collection of poems were still green with envy.

……

Jiang Xia, completely unaware of this, is facing a double bombardment from Li Huaide and Yang Youning.

"Hey, you little rascal, I won't even mention the four-cylinder engines we were assigned earlier, we're really too busy to handle them all, but you're assigning this one too?"

This was Yang Youning's voice, filled with grief and indignation.

"Oh, Xiao Jiang, this thing looks simple, but the copper tubes inside are so thin. No other factory could make it like this! It has to be our factory. Why should we do the work for someone else?"

This is Li Huaide's melodious, sweet cry.

Jiang Xia unceremoniously pushed away the two large heads that were leaning towards him.

"I need this urgently. Can you guarantee that the refrigeration system will be ready within two days?"

"can!"

The two factory directors spoke in unison.

"Nonsense! Only those units on Unit 331 that copied it before have spare parts stored..."

"Alright, the blueprints are here anyway. Once the air compressor can be made smaller, you can make the truck-mounted refrigeration unit..."

"By the way, don't you want to eat seafood during the Chinese New Year?"

Li Huaide licked his lips: "I want to!"

Yang Youning was still grumbling on the side when Jiang Xia looked at him and said, "The old company commander has lost weight again recently. I heard that seafood is quite nutritious and can also calm the nerves..."

"Oh, and one more thing! Turn this refrigeration system down a bit. If it's placed in the textile workshop, there will be a cool breeze during the hot summer..."

Tsk, thinking of his own "Shudao Mountain", Yang Youning's imagination was filled again.

"it is good!"
