Just when Lu Jiadong was pondering, Liu Liang drove the car into the Wanshan factory, and at this moment, Liu Liang glanced at the rearview mirror on the car, and saw that Lu Jiadong was still pondering, so he asked in a low voice:

"Master Lu, I'll send you home first, let's rest and rest today, can you see it?"

"Oh" After listening to Liu Liang's words, Lu Jiadong came back to his senses: "I have already made an appointment with Chief Master Zhu, I remember that his place of residence is not far from here, right?"

"It's not far, just turn a corner!"

Liu Liang said that he hit the steering wheel, and the car turned into a quiet alley, and stopped in a brand-new courtyard after a while, which is a temporary residence built by Wanshan Factory for the military experts gathered here, although it is not as luxurious as the villa of later generations, but it also has a unique charm of the southwest courtyard, and the most important thing is that it is quiet here, so it is welcomed by old military experts such as Zhu Guangrong and Liang Shouye.

At this time, Lu Jiadong had already come to the door of Zhu Guangrong's residence, stretched out his hand and knocked on the door a few times, and after a while, an extremely impatient voice came:

"Who? Didn't I say it all, wait until I'm done calculating this set of values, what do you guys do?"

"Zhu Chief, it's me, Xiao Lu!"

"Little Lu?" As soon as Lu Jiadong's words fell, he heard an incredible exclamation from the room, followed by a rush of footsteps, and then a thin, haggard but happy face appeared in front of Lu Jiadong's eyes:

"When did you come back? Why didn't you give me an early notice?"

"I called you three days ago"

"Smack~~~"

Without waiting for Lu Jiadong to finish speaking, Zhu Guangrong held the pencil hand. He slapped it on the head fiercely: "Look at me, alas! Don't say more, come in, come in, have you eaten?"

Zhu Guangrong was talking, and suddenly realized that something was wrong. Lu Jiadong and Liu Liang not only stopped the steps they had just taken, but also had a hint of strangeness on their faces, and it was only then that Zhu Guangrong found that the entire house was messed up with discarded straw paper, sketches, accidentally spilled ink, and gnawed steamed buns, so that there was no place to put his feet!

"Well, I've been so busy these days. Forgot to pack it up, or else"

"It's fine!"

Without waiting for Zhu Guangrong to finish speaking, Lu Jiadong waved his hand indifferently. In fact, his surprise was not like Liu Liang's pure surprise, but with a long-lost sense of intimacy, anyway, as a technical nerd. Lu Jiadong asked if there was no wife Chen Ziyue to help take care of it. It is estimated that it will not be much better, so when I saw the scene of Zhu Guangrong, not only did I not feel disgusted, but I got a lot closer, and then raised my eyes and asked:

"Master Zhu, do you have noodles and eggs here?"

"Yes but"

Zhu Guangrong is a little embarrassed, he has devoted his body and mind to the development of new tanks these days, which makes Zhu Guangrong, who is already not paying attention to the subtleties in life, even more so that he has no time to pay attention to the troubles outside of work, so over time. The house became what it is now, and he didn't feel anything when he went in and out alone. Now that the guests came, they knew that it was messy, so their faces turned red and looked very embarrassed, but Lu Jiadong smiled nonchalantly:

Ryoko, I haven't eaten your egg noodles for a long time, show your hand today!"

"You can rest assured, Master Lu, I guarantee that it is the same taste as Lao Wanshan Factory!" Liu Liang responded, then rolled up his sleeves and walked towards the kitchen inside, Zhu Guangrong saw this, and felt very embarrassed, looked at Liu Liang who entered the kitchen, and then looked at Lu Jiadong in front of him, he didn't know what to say for a while, Lu Jiadong naturally knew what Zhu Guangrong was thinking, stepped forward to hold Zhu Guangrong's arm, and said with a smile:

"Liangzi's poached egg noodles are a must in Wanshan Factory, you can taste it later, anyway, I haven't eaten it for a long time, and I'm a little drooling when I think about it, oh, by the way, I wish the chief master, how is our new tank going now?

Although Zhu Guangrong is an old tech nerd, his emotional intelligence is not bad, and he can naturally see that Lu Jiadong's behavior is not deliberate, so his good impression of Lu Jiadong in his heart has been raised several levels, not to mention that Lu Jiadong has also turned the topic to technology, which has also reduced Zhu Guangrong's embarrassment a lot, and his voice has returned to its former calmness:

"During your time abroad, the heat treatment of the cross-torsion tube of the torsion bar suspension system, the precision machining of the pivot bearing, the precision manufacturing of the long-barreled smoothbore gun, the mass production of the tungsten core projectile of the deshelling tail armor-piercing projectile, and the control and handling of the fire extinguishing and explosion suppression system have all been properly solved, and it should be said that most of the production processes involving the new tank have been solved, but"

As he spoke, Zhu Guangrong's face was shrouded in irrepressible helplessness and disappointment, Lu Jiadong couldn't help frowning when he saw this, and then sat down on the bench in the back room and asked puzzledly:

"Several important difficulties have been overcome, so what process can't solve?"

"Weld!"

"How can it be welding?"

Zhu Guangrong's simple two words, but Lu Jiadong was very shocked, he discussed with Zhu Guangrong before going abroad, especially in the production process of new tanks, the two initially set more than a dozen major items, nearly 100 small items of production process research planning, including welding process.

But because the difficulty of this technology is not high, the two of them invariably classified the welding process into the last few of the small projects, but they didn't expect that a few months later, all those ultra-difficult process projects were solved, but they planted a heel in the most inconspicuous welding process, which made Lu Jiadong unable to figure it out anyway.

Not to mention that Lu Jiadong couldn't figure it out, even Zhu Guangrong, who had been leading the development of the new tank in the past few months, couldn't figure it out. Although the new tank has changed from the previous cast turret to a welded turret, it should be said that it is more complicated to manufacture. However, as a product that has been used for many years and has mastered a fairly proficient production process, Zhu Guangrong believes that there is not much technical difficulty in applying the welding process on a large scale on the tank.

However, to everyone's surprise, this process that should be the most problematic has become the most problematic, and Zhu Guangrong didn't take it to heart at first, just organized the old welders and masters of several factories together. engaged in a key attack, but after a few months, there was no effect at all.

At first, Zhu Guangrong thought that the welders were cheating and refusing to contribute, but he didn't understand it until he learned more about it. The welding of the tank is not simply to put two boards together, and directly use a welding torch to burn a weld, which is a great knowledge.

So Zhu Guangrong immediately organized capable forces to tackle key problems, and the result was two months in a flash. Seeing that other supporting processes are all completed. However, the welding process has not made any progress, which directly leads to the delay in the completion of the final assembly of the new tank prototype, and it is so anxious that Zhu Guangrong jumps to his feet, but he also has to face the current reality:

"That's right, it's the welding process!"

Zhu Guangrong looked very tired in his words, one hand subconsciously put on his forehead, and gently rubbed the temples on both sides, while Lu Jiadong picked up the hot water bottle next to him. poured a glass of water for Zhu Guangrong, and then asked:

"What is the specific problem? It stands to reason that we should be very mature in the welding process!"

"Little Lou. You take a look at this first!" Zhu Guangrong first took out a copy of the materials he had just written from the desk next to him and handed it to Lu Jiadong, and then continued:

"Since the founding of the People's Republic of China, after so many years of construction, the welding process is indeed much more mature than the general processing technology, but those are ordinary welding with a relatively low technical level, and our new tank uses composite armor, and the metal characteristics and density of the material are very different from ordinary metal materials.

Therefore, ordinary welding can not be applied at all, and only high-tech welding processes such as argon arc welding can be used, but even so, due to the influence of factors such as temperature and degree of control, the outer wall of the armor is often deformed and cracked, and the weld will also appear fine cracks after cooling!

You are holding in your hand the numerical record of the welding of the top shell of the tank that I just sorted out, the armor is relatively weak, so the deformation is even more serious, and the welding seam forming is also difficult to control, just yesterday we also did experiments, such a welding effect, even ordinary bullets can not resist, and it is impossible to carry out combat missions at all!"

"That's right, materials and equipment are indeed reasons that cannot be ignored!" Lu Jiadong nodded, then put the materials in his hand aside, and said firmly again:

"But even that can be compensated for by a wealth of experience and skill!"

"Xiao Lu, although your words are good, but Wanshan, Guinan and even Yunnan factories do not have the corresponding technical accumulation in this regard, let alone experience, in fact, not to mention this Wanshan factory, which has been producing tank armored vehicles in the north, is also the first time to contact the welding turret, they also encountered similar problems, of course, their experience is definitely richer than Wanshan, so with my old relationship, I seconded a few welders with them, but if you want to completely conquer it, it will take a certain amount of time!"

As soon as he heard that Zhu Guangrong had already moved foreign aid, he asked curiously:

"How's the skill of these welders?"

"How is it? I don't think it's good!" Without waiting for Zhu Guangrong to answer, Liu Liang didn't know when he had walked in with noodles in hand, then put the noodles on the table, and continued in a complaining tone:

"Anyway, I don't think they're workers, it's more like the boss of a businessman."

"Boss~~~Boss~~~ Boss Liu!"

Liu Liang said the same thing, not only Liu Liang said the same thing, in an inconspicuous small factory on the west side of Wanshan Factory, a young man in his twenties, walking with two meat buns, shouted towards a shining spark not far away

At this moment, the shining spark suddenly went out, and in the dim light, a man flashed, holding a welding torch in one hand and a mask in the other, shouting to the young man who came in:

"If you don't come yet, I'm going to starve my grandfather to death" (To be continued.) )
