Bai Yi and Chen Yaoyang looked for prestige, only to find that the fitter Master Lei didn't know when he had entered the warehouse, and at this time, Master Lei's eyes were wide open, the cigarette bag and pot that were originally held in his left hand fell to the ground at some point, and the golden tobacco was accompanied by a little firelight, rolling on the ground, Bai Yi saw this, couldn't help but be stunned, and hurriedly asked: "Master Lei, what are you ......?"

"Chief Bai, do you really know the cold welding process?" Master Lei didn't care about the cigarette pouch and pot under his feet at all, and stepped forward with an arrow, his heavy and powerful left hand pinched Bai Yi's arm, his face was eager, his eyes looked at Bai Yi in front of him excitedly, and asked again: "Do you really know the cold welding process?" ”

"Uh...... Not too much, but generally understand! Bai Yi was taken aback by Master Lei's sudden move, and then grinned again, Master Lei seemed to find that the strength in his hand was too great, so he hurriedly let go of his hand and said apologetically: "I'm really sorry, I really ...... after listening to the cold welding process It's really ...... Alas...... Speaking of which, our craftsmanship is too poor, otherwise ......"

As he spoke, he glanced meaningfully at the scrapped machinery in the warehouse, and sighed helplessly: "Otherwise, there wouldn't be so many machines that would be treated as scrap!" ”

It turned out that Master Lei had been exposed to the cold welding process in his early years, which was still in the warlord period, because most of the machinery and equipment of Baiyun Factory were purchased from Europe, so the maintenance of the machinery also needed to be carried out by European engineers, and the repair of damaged guide rails of machine tools was an important part of it. Pen ~ fun ~ pavilion www.biquge.info

At the beginning, the Europeans repaired the guide rail method is not unusual, basically to replace, but just a year before the surrender of Japan, Baiyun factory suddenly came a group of German engineers, they are very unique in the maintenance method of the equipment, especially the repair of the guide rail is an unprecedented method, not only simple, fast, after the repair is even more firm and abnormal, not even a trace of repair can not be seen, not to mention the Chinese workers at that time, that is, those Japanese engineers who think very highly of themselves are dumbfounded.

"It wasn't until Japan surrendered in 45 that the captured Japanese engineers confessed that the German engineers' method of repairing the guide rails was called the cold welding process, and those little Japan also knew this, because the Germans also regarded this process as a treasure, and even their allies the Japanese were not allowed to touch it.

Back then, thanks to my kid Spirit, I secretly watched the on-site operation of some Germans, and I also thought of some ways afterwards, but after many years, nothing was achieved, and I could only watch these good machines scrapped one by one, alas......"

Master Lei's last sigh expressed his extreme helplessness, no way, for the current China, every machine is a valuable asset, but often for various reasons, the broken machinery cannot be repaired, and becomes a pile of scrap iron, which may be because of a screw, maybe because of a small gap.

After 70 years, this trivial problem may not be surprising, a student who has just graduated from a technical school may fix it, but at the beginning of 49 years today, because of the lack of advanced technology and means, these small problems will become a fatal killer of a machine, in a word, there is no industrial base in China, there is no ability to maintain the machine!

Looking at Master Lei, who was beating his feet and beating his chest, Bai Yi's heart was also mixed, but more urgent, so Bai Yi stepped forward and grabbed Master Lei's left hand and said warmly: "Master Lei, don't be sad, it may not work if it's too complicated, but it's not too much of a problem to repair a guide rail strain!" ”

"Really?" When Master Lei heard this, the sadness on his face was suddenly swept away, and Bai Yi nodded: "Really, I also came back from the Soviet Union, before I joined the Soviet Army, I also interned in their factory, I have seen this kind of process, it sounds very powerful, it is nothing more than using some media such as iron powder, with a certain proportion of adhesive, under the condition of room temperature, the method of bonding steel and other materials together!" ”

The cold welding process is actually a gluing method, but the process is more complicated, and most of the glued materials are industrial parts such as metal, because it produces the same effect as welding, and there is no high temperature generated during welding, so it is called "cold welding process".

Bai Yi also learned this process when he was a graduate student in his previous life, but it was carried out with a more advanced cold welding machine at that time, but his tutor still introduced a more basic cold welding process, after all, most of them who studied military equipment had to be assigned to the logistics and maintenance department of the army and serve as professional maintenance personnel of the equipment.

Under actual combat conditions, if the cold welding machine fails, and the equipment needs to be repaired by the cold welding process, it needs a more concise and fast method, and the basic cold welding process just solves this problem, as for the "building block" machine tool is the same, field maintenance is not so particular, how simple how to come, and the "building block" machine tool is a good way to adapt measures to local conditions that Bai Yi learned.

It's just that what I didn't expect is that what I learned in my previous life has become the golden finger of today's emergency, Bai Yi sighed that creation made people at the same time, but also glad that he was not bothered by the world when he was in the military school, and studied seriously, otherwise at this moment, he would also face these "scrap copper and rotten iron" will also be one head and two big!

Of course, Bai Yi can't say anything about these situations, but fortunately, his body has the experience of studying in the Soviet Union and serving in the army, which can be used by Bai Yi to dig well, as for whether someone will investigate this in the future, Bai Yi is not very worried.

In those years, the Soviet Union was fighting against Germany again, and it was a mess for a long time, even the high-ranking Soviet marshal had some inexplicable deeds, let alone his little student soldier, so where to push everything to the Soviet Union, Bai Yi said that there was no pressure.

"Cold welding process? Chief Baike, did you say that this cold welding process is not the kind that is burned by fire, but glued? ”

After listening to the conversation between Bai Yi and Master Lei, Chen Yaoyang on the side suddenly had a little insufficient head, just started listening to the cold welding process, he thought that he was using a welding machine to burn the metal up, but when he heard it, he realized that it was not like that at all, people were glued, which simply subverted his previous inherent thinking, he couldn't help but widen his eyes, looked at Bai Yi in surprise, and asked noncommittally: "Is this ...... This...... Will this work? ”
