In machining, there is no doubt about the importance of machining technology. Which process is in the front and which process is in the back are all particular, otherwise there will be a big problem.

That's why even the smallest factory has to have a process technician. A master like Yunkai is a master who concentrates on production scheduling, process arrangement, design programming and a series of other types of work. These things all go hand in hand.

After the design, it is necessary to take into account the process arrangement in the processing process, such a design can be processed, what kind of processing technology is used to reduce the cost and better effect? When arranging production work, we have to consider the process more, which process is ahead? Is the production capacity in your own hands able to do such a design requirement?

And so on and so forth, all of which have to be considered for craftsmanship.

But this tyrant in front of him is a bit of a tyrant, and he is not too young to see that he has been in this industry for many years, right? How can you not even know this most basic common sense?

How can this not make Yunkai's egg hurt?

"Uh, Brother Yun, can't aluminum alloy be welded and then heat treated?" Xu Changshuai asked in surprise, this guy in front of him can't fool himself, right?

At this time, his name for Yun Kai changed again.

"I don't think so. When the aluminum alloy is welded, a large amount of internal stress will be generated, and during heat treatment, the position of the weld is different from the hardness of the parts at both ends, and the internal stress is also different, which will cause the weld to crack because of the concentrated release of internal stress...... "Huang Kui is also a little uncertain, although he studied mechanics, but not specialized in materials.

Moreover, after coming out, I have always been engaged in machine tool sales, and I often deal with Yunkai who is engaged in technology, masters who understand craftsmanship and those bosses, for such a long time, I have never heard of anything to go to metal parts that can be heat treated after welding.

"No, it doesn't seem like it can't. It's simply not at all. The principle of what Huang Kui said is similar, and I don't bother to explain it to you, if you don't understand, you can ask others...... It's a shame that you've been in this industry for so many years! Yun Kai is still very disdainful of the tyrant in front of him.

Nima, isn't this an insult to your own skills!

"Well, Brother Yun, my master told me that a very hard material like high steel cannot be heat treated after welding. There is no problem with other softer materials......" Xu Changshuai said with an embarrassed face.

As soon as the connoisseur makes a move, he will know if there is one.

This Yunkai really deserves to be the first person of these small machine processing factory masters here in the Economic Development Zone!

"Nima, who sued you? If your master is in front of this, I have to give him a few slaps, such a person can also lead an apprentice? Isn't that? It's no wonder that young people nowadays are getting more and more rubbish ...... technology," Yunkai really hurts.

Angry. It's not because the guy in front of him doesn't know how to mess around, but because of his master.

Teacher, preach and teach to solve doubts.

But how can these irresponsible guys not make people angry when they teach their disciples like this? Although these are not related to Yunkai's dime, he has a very deep affection for this industry.

Originally, the machining industry has basically been faulted and learned technology in this era. It's not as much money as moving bricks on a construction site.

Your skills are not good, there is no problem when you are a master, after all, there is a teacher in a threesome. But if you don't know, you can't teach indiscriminately, right?

This is the simplest common sense problem, in case you encounter such a strange thing in the process personnel recruited by yourself in the future, then you still have to?

Moreover, the general company recruiting process technicians will not ask these basic questions.

"Yo. Handsome guy, you seem to be very old......" At this time, a girl with a pointed chin on Xu Changshuai's left said to Yun Kai dissatisfiedly.

This guy has been booming since he came in, and he didn't even stare at them, and he said things that were like listening to heaven for women like them.

"He is not old, but he has an ......old mentality," Huang Kui said with a smile for that woman.

"Forget it. I'm too lazy to tell you this, you won't understand it anyway......" Yun Kai's egg hurt, and seeing Xu Changshuai kiss the face of the woman on his left as if rewarding, Yun Kai was depressed.

This grandson. This is obviously showing off!

Nima, who only has tens of millions on hand, runs in front of himself to sè?

"Brother, give me a face......" Huang Kui saw that Yun Kai was leaving, and immediately became anxious, hugged Yun Kai, and whispered.

"Xiaoli, go outside to see why the food hasn't come up yet, what's the matter, I'm worried that we can't afford to pay or what?" Seeing that Yun Kai was angry, Xu Changshuai remembered that people with skills are people with tempers.

After the woman with a pointed chin named Xiaoli next to him left, Xu Changshuai said to Yun Kai: "Master Yun, I'm sorry, this girl is learning foreign languages, and she doesn't know anything about our business. I'm really asking you for advice, can you popularize these basic common sense? ”

"......" Yun Kai was speechless. Is this grandson's character flawed?

"Brother, I don't know much about these, popularize it, and go out in the future to fool people, right?" Huang Kui was also saying good things to Yun Kai on the side, and he blinked from time to time.

"Okay, I'll just talk about some basic things that I know, these things are right, I don't guarantee ......," Yun Kai said bitterly.

Huang Kui helped Xingmeng Machinery buy equipment, but he rarely made their money, and the local tyrant in front of him definitely made Huang Kui earn a lot, and it is very likely that he will buy it, so Huang Kui is so anxious.

"Any metal part, even if it is heat treated, must be completed before welding, because when welding, some of the physical properties of the material are changed, especially the position of the weld on both sides of the weld where it is connected to the welding material, which will generate a lot of stress. Some small parts are welded, and they may not be welded through because the welding technology is not up to par, so it is easy to crack in the case of sudden force...... "Yun Kai used his professional knowledge to explain to this tyrant, just like Huang Kuina's grandson said, these professional can fool people.

In fact, he said so much, it was simply a bunch of nonsense, and even if he said it, it would be difficult for a half-witted person like Xu Changshuai to understand.

What this stress is and how it is generated, I don't know what it is, unless I am a person who often deals with materials and various heat treatment processes, I can't understand it at all.

"Brother Yun, do you mean that any metal parts cannot be heat treated after welding?" was fooled by Yun Kai as if he was riding a rocket, knowing that Yun Kai stopped for a while, Xu Changshuai reacted.

"Yes!" At this time, the dishes were already coming up, and after Yun Kai sandwiched the plate of lobsters that were originally only one to Li Yun, who had not spoken all this time, he took a sip of wine before answering lightly.

There is only one lobster, and I don't know what this grandson thinks, if you want to be rich, you won't pick the door like this, right? How nice it is for one person!

"But my shelf is not heat-treated, what if the strength can't go up?" Xu Changshuai said in surprise. For Yun Kai's behavior, he was not surprised at all.

He is also from the front line of the workshop, and he knows that no matter how good the technology is, the salary will not be too high. However, Xiaoli with a pointed chin next to him was suddenly unhappy.

"Change the design, change the connection method, or change the material, use Tc4 titanium alloy, or stainless steel strength is much higher than 6o61 civil aluminum alloy ......"

"I've also considered stainless steel, but it's too heavy, and the cost of titanium alloy is too high," Xu Changshuai said embarrassedly......

After all, he is not a professional designer, for these things, he is completely confused, and he didn't learn much when he was a worker, and he knew everything very well through Guò Du Niang.

He didn't know at all that there were many professional things that he couldn't find on Du Niang, and they were all things that some half-guys like him came up with based on their own imagination in order to mix experience......

"Do you have the drawings with you? Show me......" Yun Kai gave Li Yun a few abalone again before saying to Xu Changshuai.

And Huang Kui's guy was also looking at the woman named Zhang Yi beside him at this time, as if no one owed her 1,800 yuan and hadn't paid it back, and he had always been courteous to the woman who had not said a word for so long.

Yun Kai estimated that this grandson should be chasing this sister. Otherwise, as soon as these dishes came up, he just grabbed the only lobster clip and gave it to Li Yun beside him, and he also picked up the things that were usually difficult to eat on the table for the women around him, such as abalone or something, for the woman's bowl......

"I haven't finished eating here yet......" Li Yun saw that the two women beside Xu Changshuai opposite were staring at him with angry eyes, and her face was suddenly covered with red clouds.

Yun Kai did this, it was really embarrassing, but she was full of joy, this man was ashamed of himself.

She also knew that with Yun Kai's current net worth, she didn't care about this thing at all, and probably deliberately pretended to look like she had never seen the world to disgust the woman who had offended him just now.

"Brother, you still have to leave me some......" On this table, not only Yun Kai can be cheap, Huang Kui also doesn't care, after filling the bowl for Zhang Yi, he is also doing a lot of work, and a plate of ten abalone suddenly disappeared.

However, after seeing Yun Kai bring that elbow in front of him, he immediately jumped up.

Yun Kai is a carnivore, so is he, elbows are his favorite, I didn't expect to be occupied by Yun Kai, how is this?

"You haven't eaten in eight lifetimes, or what's wrong?" At this moment, Xiaoli next to Xu Changshuai suddenly slapped heavily on the table and angrily scolded the two who grabbed the elbow.

And next to Xu Changshuai, another melon-seed-faced woman who has always pretended to be calm, with a faint smile on her face, and does not intervene, is also full of disdain......
